FAQ's

UPDATE 14/01/22: PLEASE EXPECT EXTREME SHIPPING DELAYS.

All couriers including: Australia Post, Aramex (formerly Fastway) Couriers Please, Toll & FedEx (formerly TNT) are experiencing extreme volumes of parcels and limited staff resulting in shipping delays. 

All courier services are still delivering during this time however with lockdowns, temporary facility closures, fewer flights and limited staff there are significant delays in the estimated delivery times. 

From the couriers:

Like many businesses in Australia, several of our depots have been impacted by positive COVID cases and the necessary isolation time required to ensure safe re-entry to the workplace. This has had a flow-on effect to our call centre teams and our Courier Franchisees. As many businesses have not yet re-opened after the holidays, this is causing additional delays.

The regions most impacted are Melbourne, Sydney, Adelaide, Geelong and Bendigo, with delays of 3-5 days for delivery into these regions. Perth is also experiencing delays of up to 5 days as a result of unprecedented delivery demand and staffing shortages.

Our U RESIN Flex UV, Standard UV, Thick UV & Liquid Glass resin systems are all a simple 1:1 ratio by volume.

This means for a total of 200ml, you will require 100ml of Part A (Resin) & 100ml of Part B (Hardener)

This depends on the ambient temperature as well as the temperature of the resin.
When both the resin and room temperatures are between 22- 25 degrees Celsius the working time for our art systems are between 45-60 minutes.

The cooler the resin and weather, the longer the working time you will have. The warmer the resin and weather, the shorter the working time you will have.

Ideally the temperature for both the resin itself and room/working area should be between 22 - 25 degrees Celsius.

Avoid working in high humidity as this can affect the finish of your project.

Our Artwork resins have a Pot Life of 45-60minutes depending on the temperature of both the Resin and the Room. (Refer to "What is the pot life of the Art Resins?") 

If the outside/room temperatures are higher than the recommended 22-25degrees, then this will also mean the temperature of the resins are higher and will lead to the resin having an accelerated curing time.
I.E. If the temperature is 30degrees, you may find you only have a working time of 30-45minutes.  

Overheating your resin whilst working with it, can also increase the cure time and lower the working time of the resin. It is important to keep your heating element (heat gun, butane torch, etc.) at least 20cm away from the resin surface and ensure you keep moving the heat source, rather than heating in one spot for too long. 

Too much pigment (Excess of 10% colour to resin) in your resin will also lead to the resin speeding up as this is changing the natural chemistry of the resin. 

Finally, high volumes of resin can also cause the resin to cure faster. The more volume in the cup, the more of an exothermic reaction is created which will lead to the resin going off faster. To prolong this process, it is best to seperate the mixed resin into smaller cups (with your pigments, etc.) and not allow large volumes in one particular container. 

We recommend using either our 400ml, 1L or 2L Measuring jugs with measurements provided which you can measure equal parts of A and B into before mixing.
With a stirrer or scraper begin mixing the resin and hardener together.
Mix for 2 minutes ensuring you scrape the sides/walls and the bottom/edges of the container. Once you have mixed well, we recommend pouring the mixed material into a new measuring container and mixing for an additional 1 minute, for the best results.

All of our resin systems have varying temperature resistances. All temperature resistances are based off the cured and post cured, CLEAR epoxy resin. It is also based on a minimum pour depth. Meaning if the resin is poured less than the minimum depth, it can result in being softer, which would have a lower heat tolerance.

Please note that temperature resistances will vary when additives or colours are used, as this changes the natural chemistry of the resin.

Below are the temperature resistances of each system:

- U RESIN Flex UV can withstand up to 50 Degrees Celsius

- U RESIN Standard UV can withstand up to 80 Degrees Celsius

- U RESIN Liquid Glass can withstand up to 90 Degrees Celsius

- U RESIN Cast can withstand up to 110 Degrees Celsius

- U RESIN OceanCast can withstand up to 110 Degrees Celsius

Our Coating systems (U RESIN Flex UV, Standard UV & Liquid Glass) are based on a minimum depth of 2mm.
Our U RESIN Cast system is based on a minimum depth of 10mm.
Our U RESIN OceanCast system is based on a minimum depth of 50mm.

If the resin is being used for something that contains heat, (for example U RESIN Liquid Glass is being used on a coaster) if a coffee cup were to sit on the coaster and it softens, this is not to worry. Once the heat source has been removed, the resin will return back to its original hardness.

Definitely Not!! Water will not help and only ruin your art. Water-based products are also no good for resin art as water and resin will repel and cause issues when trying to cure. 

Safety is extremely important, especially when working with epoxy resins!

If you are under 16 years of age or pregnant, please DO NOT use epoxy resin (of any brand). 

All of our products come with basic safety & working instructions. We would also recommend finding a suitable and comfortable respirator with P2 filter protection, if you are unable to work in a well ventilated, low-traffic area.
Nitrile gloves should also be worn whenever handling or working with resin. 

For more information on Safety Procedures, please email us with the resin system you are using, for a digital copy of the (M) SDS.

We recommend you don't.
Our Systems have been primarily designed for art purposes and do not have the correct properties for using as a kitchen surface/ high wearing surface top. 
If you are creating coffee tables, or more decorative tables/ display pieces with low wear and use, then our systems will be fine to use. As they are designed for Art.

We would recommend the U RESIN Liquid Glass system for decorative table tops. 

If you are trying to create cells or lacing in your resin artwork, we have described the best techniques on how to create them.

You can read more about creating cells and lacing here: https://www.uresin.com.au/blog/how-to-create-cells-lacing/

Absolutely! Whilst a new layer can be done sooner, for the best surface and adhesion, we recommend letting the initial resin layer to cure for 24 hours before pouring additional layer.
If you are leaving the piece for longer than 24 hours, we recommend you sand the artwork first, to ensure better adhesion to the new layer.
The possibilities are endless, as are the layers! 

This yellowing is due to oxidisation of the Hardener (similar to a banana). The more air/moisture it is exposed too whilst unmixed, the more noticeable the yellowing will appear. The longer the Part B sits or is left open the quicker the yellowing will occur.

Yellowing is generally more noticeable in large volumes (i.e. will be more noticeable in a 5L bottle as opposed to a 500ml bottle which less volume)

The Resin is still perfectly fine to use, and you will notice that once it is mixed together with the Part A, the colour will dilute and be clear to use with pigments, etc. 

To delay the yellowing, make sure the resin is away from direct sunlight and kept in a dark dry and preferably cool area, with the lids tightly sealed. 

No.
As each resin is formulated differently, it is best to avoid mixing different resins together.

By mixing resins together, you make get dimples, webbing or tacky spots (just to name a few) throughout the art due to a reaction or lack thereof between different brands.
However, applying separate layers of resin on a piece of art is completely ok. We recommend sanding in-between layers. 

Artworks can become dimpled or rippled from a number of factors, including but not limited to the following: 

1. Type of resin - some resins are far too thin/ low viscosity and when applied to a surface will not cover the surface enough. 

2. Unmixed/ Uncured resin - When the proper reaction has not occurred or the resin is not properly mixed this can cause issues in the art.

3. Using a heat gun or flame too close or for too long to the resin can also cause ripples and dimples.

4. Not enough resin - If a board is 40cm and requires 300ml of resin, we generally recommend mixing and applying more and allowing the excess to drip off. By applying less than necessary and trying to stretch it, can cause the resin to dimple. 

5. Contamination - If you are using alcohol inks, oil paints, or there is an oily residue on the surface and it is not completely dry or cleaned prior to applying resin, this can also dimple as the resin will repel. 

Resin can remain sticky or tacky for a couple of reasons:

1. Bad mixing - If your resin was not mixed thoroughly for 2-3 minutes, scrapping the sides and bottom of the container, there can be unmixed resin on your piece.

2. Incorrect ratios - If you have too much resin or hardener, there is excess of one part that has nothing to bond too, which will leave tackiness on the art surface. 

3. Contamination - If there is something existing on the surface or something that is mixed into the resin that acts as a repellent, this can cause the resin to stay uncured and tacky. 

Yes, you can add as many pigments to your artwork as possible. 

We generally stick to a simple rule of 5 colours when creating an artwork: Black or White - Light, Medium, Dark Shade and a Metallic. 

Colour pigments can be mixed together to create a new shade of colour, turn a transparent pigment opaque or turn a pigment metallic/ shimmery. 

Whilst you can use many colours, we recommend only using 2-5% colour pigment to resin ratio to ensure the best effect and finish.

Both the Part A Resin and Part B Hardener have different densities which means that both parts have different weights.

For our 'Art Resins', the Part B is heavier than the Part A resin.
For our 'Casting Resins' the Part A is heavier than the Part B Hardener.

When measuring out by volume, depending on the ambient temperature (hotter or colder), this changes the specific gravity of the material which can affect the measurements being used. Hence why it isn’t unusual to have some of one component leftover.

However, Please Note: By adding more hardener to the system will not 'kick' or speed up the epoxy. By altering the ratios, it can cause excessive blushing. negatively affect the cured strengths and curing times and potentially ruin the finish over time.

If you are going to use Alcohol Inks in or with epoxy resin we recommend testing in small amounts/ samples first.

As alcohol inks are solvent-based they can react very differently in each resin system. Every epoxy resin system is formulated differently and contain varying ingredients, so no 2 resins will provide the exact same results each time. 

By adding Alcohol Inks into resin, will cause the resin to become highly flammable if exposed to excessive heat or a direct flame. 
As alcohol inks are not lightfast colourants, they will generally always fade, bleed or change colour. In some instances this is straight away, and for others it can be days, months or years. There is no specific timeframe of when this will occur. 
We would recommend the use of the Epoxy pastes in minute amounts to create a transparent effect for the best results. 

We do our best to have consistent supply of the range of pigments we manufacture. However sometimes if a raw ingredient is unavailable or delayed, this can cause delays in us being able to remanufacture. 

UPDATE: 15/11/21: Any colour that is currently out of stock, will not be available until the new year, after our Christmas Break. 

Unfortunately, due to current workload, we do not have the current capacity or raw materials to re-manufacture our colour range at this time.

Our U RESIN Balm is 100% made of a blend of Natural Bees Wax and Citrus Oil. It is made in Australia and from all locally sourced materials making it food safe as well as smell great. 

Yes, the measuring cups you can find on our website here can easily be reused, as long as you have measured and mixed correctly. 

There are a few ways for the measuring jugs to be cleaned and reused: 

1. Leave your mixing stick in the jug and allow it to cure, then using the mixing stick, pull the hardened resin out. 
2. Leave the resin to cure at the bottom, then once cured push around the sides and bottom of the jug to create an air pocket and then pull the hardened resin out. 
3. Tip the measuring jug upside down onto painters plastic or a drop sheet and all the resin to drain out. Then peel off once the resin has cured. 
Solvent (i.e. Isopropyl Alcohol) can then be used to wipe the jug clean if needed. Ensure the jug is thoroughly dry before re-using with resin to avoid any contamination.

Alternatively, silicone measuring cups can easily be wiped out and cleaned straight after use, or the resin can be peeled out once hardened. We would recommend avoiding solvents to clean the jug as this will deteriorate the silicone jug and make them unusable. 

Resin can be quite the sticky mess, meaning if you aren't careful it can get all over your tools and accessories that you are using. Here are the best ways to clean and keep clean, the tools you use. 

1. Heat Guns - Cover the handle and switch with masking tape and remove once dirty/ hard. If your switch gets stuck, use another heat source to warm the resin and scrape off with a sharp tool, until it can be moved again. 
2. Measuring Cups - See "Can I re-use my measuring cups?" 
3. Mixing Sticks - If you are using a wooden mixer, the resin can be cut or sanded down to be reused, however we generally would not recommend this. Using a Plastic mixer would be a much better alternative and wiping with Isopropyl Alcohol after use. 
4. Pigments - Using a baby wipe drenched in white vinegar is the safest way to clean up spilled pigment. 
5. Accessories - If the tools are made from polypropylene or polyethylene, the resin should not stick, and once cured can be peeled off and reused. Alternatively wiping the tools down straight after use with Isopropyl Alcohol will also help keep the tools clean and reusable.  
6. Painters Plastic - Resin will not stick to painters plastic, so this is the best option to use on your table and floor surfaces as once the resin has cured, it can easily be peeled off.

Ensure your artworks have no sticky spots or uncured resin, and allow the artworks to fully cure before packing and shipping to your customers. 

We have a video available on our YouTube Channel with how we pack artworks before shipping them off. Find our video here.

We would also recommend wrapping in tissue paper first, and then finishing with cardboard or a box to ensure the best safety of your artworks when shipping. Fragile tape or stickers are also handy.

Our U RESIN Cast & OceanCast resin systems are all a simple 2:1 ratio by volume.

This means for a total of 300ml, you will require 200ml of Part A (Resin) & 100ml of Part B (Hardener)

Yes, Absolutely! 

We have 2 main epoxy resin systems designed for these purposes: U RESIN Cast & U RESIN OceanCast.

Both offer slightly different properties, however work in the same way. You can find the full information on both in the description section of each product in the 'Shop' 

Click here to download your FREE .pdf on how to use our U RESIN Cast system. 

Click here to download your FREE .pdf on how to use our U RESIN OceanCast system. 

Our U RESIN Cast has a pot life of 50 minutes at ambient temperature. It is a very fast curing system with a High Exothermic temperature.

Our U RESIN OceanCast has a pot life of 280 minutes at ambient temperature. It is a very slow curing system with a medium-low Exothermic temperature.

You can find more information for each product under their description in the 'shop' section.

This depends on the ambient temperature, resin temperature, type of resin and volume of resin that is poured. 

Generally for our Art Resins, after the pot life is finished, it will be touch dry in 6-8 hours. 

For our U RESIN Cast, after the pot life is finished, it is generally touch dry in 4 hours. 

U RESIN OceanCast, after the pot life is finished, is generally touch dry in 48 hours. 

Again, temperature and volume dependent for each system. Overall the warmer the room and resin, the faster the cure time. The cooler the resin and room, the slower the cure time. 

A full/post cure is 7-10 days after becoming touch dry. However, this is based on the clear resin itself and an average temperature of 22-255 degrees celsius. If it is colder (Winter time) resin will take longer to fully cure and we would recommend upwards of 21 days if you are creating items (i.e. coasters) to sell. 

Our U RESIN Cast is designed to be poured anywhere between 5 - 20mm per layer. Additional layers can be poured once initial layer has cured to build up to the desired thickness. 

Our U RESIN OceanCast is designed unlike any other system available in Australia. It can be poured anywhere between 50 - 100mm per layer. We recommend that you do not pour less than 50mm deep, due to the very slow cure time. 

You can find more information on each product in their description in the 'Shop' section.

Safety is extremely important, especially when working with epoxy resins!

If you are under 16 years of age or pregnant, please DO NOT use epoxy resin (of any brand). 

All of our products come with basic safety & working instructions. We would also recommend finding a suitable and comfortable respirator with P2 filter protection, if you are unable to work in a well ventilated, low-traffic area.
Nitrile gloves should also be worn whenever handling or working with resin. 

For more information on Safety Procedures, please email us for a digital copy of the (M) SDS. 

Ensure that you store your Resins in a cool, dry area.
Do not allow for direct sunlight as this will cause the resin to yellow.

Yes, absolutely. 

Ensure your resin has cured completely for a minimum of 48 hours before sanding. 

Any sandpaper grit will work with resin. By re-coating the resin, it will remove any visible scratches made to the bottom layer. 

Yes. Any of the pigments, powders or pastes available on our website can be added into our U RESIN Cast or OceanCast systems to create a river table or other casted object. 

See 'How much pigments should I add?' for more information. 

When creating a river table or other casted objects, we recommend adding no more than 10% colour to resin.
Ideally, 2-5% of colour to resin for the best results.

The more pigment that is added the more concentrated the colour will be. 

Any more pigment in the resin can cause the resin to be uncured or soften the resin. 

If you are using moulds (i.e. Jewellery, coasters, etc.) and want a clear pour, you are best to use our U RESIN Cast system.
This system has been designed to be poured in 5-20mm thickness with crystal clear clarity.

Colours can also be added to these pours. 

Our Flex UV, Standard UV, Thick UV & Liquid Glass have all been designed as flat surface art coatings and will become cloudy, the thicker the (clear) pour. 

Find our U RESIN Cast & Liquid Glass systems used in moulds on our Youtube Channel: https://www.youtube.com/channel/UCbIJ7BwoSuSh0rDcs3mZVRQ

Epoxy resin generally does not stick to polypropylene, polyethylene & Silicone. 

These are the best materials to create a mould from, however it would depend on the overall size. 

Melamine or ply are also options for large moulds, however you will need a good form of release. "Sheathing tape" is a good option to line the moulds with, however we would still recommend the use of a release agent. 

A silicone spray like: EaseRelease or a release wax will work as good agents to assist in de-moulding. 

Depending on what material your mould is made from, most can be re-used when taken care of. 

Silicone Moulds - Silicone moulds can easily be reused countless times as long as heat sources and solvents are kept away from the silicone surface. Both these things will deteriorate the silicone, meaning you will get less uses out of them. By using a Silicone Mould Release Spray, before pouring your items will also help prolong the life of the mould for more uses.

HDPE - High Density Polyethylene is a great mould option, especially for larger casting projects.  It is a very versatile thermoplastic that will provide both support and a good quality finish to your project. Again this can be reused if taken care of, and a Silicone Spray would be recommended for prolonged use. 

Melamine - Melamine is a great and more cost effective mould substrate for large projects like river tables. However, these can be a little harder to reuse, as if it is not properly conditioned beforehand the resin can stick, and make result in mould breakage. A Silicone Wax or Mould Spray is highly recommended as well as a sheathing tape on the base and sides for better mould release. 

Both our U RESIN Cast and U RESIN OceanCast can be turned on a lathe once they have fully cured. 

We would recommend either our U RESIN Cast or U RESIN OceanCast for casting/ deep pours depending on how you are wanting to create your project. 

U RESIN Cast  www.uresin.com.au/product-category/u-resin-cast/ - This is suitable for casting 5 - 20mm in 1 pour, per layer (so 2-3 layers would be necessary for your projects). It is a fast curing & High exothermic system meaning you would be able to re-pour another layer 4-6 hours after the gel (temperature dependent). 

U RESIN OceanCast www.uresin.com.au/product-category/u-resin-oceancast/ - This is suitable for casting 50 - 100mm in 1 pour, per layer. It is possible to pour 35-50mm thick, however as it is a very slow curing & Low exotherm system it would mean your de-mould time would be longer than normal. However, this would be the best option if you are wanting to do a single layer pour. 

If the U RESIN Cast is poured deeper than the 20mm depth limit, it will create a very high exothermic reaction. 

U RESIN Cast has a naturally high exothermic temperature when poured between 5 - 20mm. When poured over this amount, it will overheat the resin which will cause the resin to smoke and potentially crack, among other issues. 

If the resin cracks during your pour, it is not all bad news! It can be patched by re-pouring resin into the cracks/gaps. 

By pouring below the recommended minimum depth for U RESIN Cast can cause the resin to appear webbed or mirky looking. The resin needs to reach the minimum depth to allow the exothermic reaction to occur and provide a glossy-like finish. 
If you are wanting to pour below the 5mm minimum depth, we recommend you use our U RESIN Liquid Glass system instead. 

By pouring below the recommended minimum depth for U RESIN OceanCast, this will slow down the cure time much further. All information on the product is based on a 50mm pour. It is a naturally slow curing system with a low exothermic reaction, so by pouring below the recommended amount can increase the cure time by more than 48 hours. (Results and cure times will significantly vary depending on the total weight and volume of the pour).

Micro bubbles are one of those quite difficult things to deal with in projects that can sometimes be unavoidable. Generally speaking, there are a few reasons why they occur:

1. Moisture Contaminated Resin - If you are working with 'old' resin (perhaps that has been used/ opened multiple times before) this will mean, over time moisture has entered the containers which would have reacted with the resin. The older the resin, the higher chances of micro bubbles forming.

2. Unsealed Surfaces - This is a huge one, as most timber surfaces will need some kind of sealer to ensure the resin does not react with any moisture or contaminants. See our Blog Post for more info.

3. Additives/ Embedding - Items like coffee beans, flowers, shells or similar, if not properly

4. Excess Heating - When working with heat, it is very important to keep the heat source moving and not stay in one spot. By giving excess heat to one spot, will leave to more bubbles forming as it is accelerating the curing process of the resin.

Bubbles will naturally occur during the mixing process. If you are using a drill for a large volume pour, this will draw more air into the resin and cause more bubbles to form. 

Once you begin to pour your resin, bubbles will begin to automatically disperse at the U RESIN Cast & OceanCast are very low viscosity systems, with excellent bubble dispersing properties. 

We recommend you avoid excess heating of the resin, as this will increase the resin temperature and can cause a faster exothermic reaction. Pour you resin, and allow the resin to flow and self-level and disperse bubbles on its own. After 5-10mins with a butane torch (or similar) very lightly move the heat over the resin from approx. 10cm away and hover over the entire surface. Keep the heat moving and avoid staying in one spot as this can scorch the resin and cause it to smoke. 

If you have mixed and poured your resin and notice it is smoking, this can be caused from too much heat being added to the resin or by the volume being poured. 

By constantly applying heat to the resin to remove bubbles, will cause the resin to heat up faster than normal and cause smoke. 

If you have poured a substantial volume of resin or poured past the recommended maximum depth, this can cause the resin to create a high exothermic reaction, which can cause the resin to smoke. The more volume, the more heat will be generated. 

It is very possible for the U RESIN Cast or U RESIN OceanCast to crack. This is generally caused by the exothermic reaction (high volume pours) or if the resin was restricted/braced in some way. 

If you do have cracks in your pour, by gently separating the cracks further with a flat head screwdriver or similar, and re-pouring resin into the cracks, will allow the cracks to fill and cover any significant difference between the pours. 

When purchasing either our U RESIN Cast and U RESIN OceanCast systems you may notice that the bottles/ kegs are not entirely full. This can be shown in the product images on our website. 

To assist it keeping our products as cost effective as possible, we use a range of bottles and kegs that are universal to fit all of our resin systems in. The bottles are then filled to the specific weight size for each particular resin kit. 

For example, a 6L U RESIN Cast kit will be packed as: 

Part A Resin: 4000mls (4 Litres) in a 5 Litre Bottle 
Part B Hardener: 2000mls (2 Litres) in a 2 Litre Bottle. 

If you are pouring on an art board or just trying to create a small barrier to avoid resin spillage, masking tape can be used. Depending on the area you are trying to dam, we would generally recommend 2-3 layers of tape in a criss cross pattern to create the best barrier and support for the resin. 

If you are pouring in a large mould, creating river tables and are trying to find a non-sticking tape, we would recommend the use of a sheathing tape, similar to the American brand; Tuck Tape.
