Q: I want to create coasters, which JR resin should I use?

For casting solid resin coasters, we suggest our ArtCast Slow Set epoxy. If you’re coating mdf coasters, we suggest DiamondCote, or Art Resin. We suggest to allow approximately 14days to cure prior to placing items on top of the surface. More detailed info on our resins and project compatibility can be found here.

Q: Can I place food on the Resin Section of my project?

Food safety & epoxy resin: Epoxy Resin generally speaking, is completely cured at 7days (when mixed & measured correctly, and allowed to cure in appropriate conditions), which means it is stable and inert - and in-turn complies with FDA regulations. FDA regulations for cured epoxy resin and food contact, generally refers to indirect contact. The above is relevant when there are no pigments added, so a clear coat may be required over your pigmented layer. To our knowledge, there is no FDA certification for Epoxy Resin & Food Safety. You can also access our Safety Data Sheets here for further information. A few things to note - Food safe & epoxy resin generally refers to indirect contact. For coating serving boards, we suggest pouring on the handles of the board, and not over the entire board. A coating epoxy, like ArtCote or DiamondCote is most ideal. You could sand and polish the surface of your epoxy resin project and apply a food safe wax if you chose. You can coat/cast with an epoxy resin, then apply a coat of our WaterCote polyurethane, which is food safe, if you chose. It can be applied by pouring or by brush, roller or by spray (upon dilution) and is self-levelling. Keeping in mind an epoxy resin surface should not be cut on. We suggest not applying any brand of epoxy resin where one’s lip will touch . Kindly note our WaterCote & Epoxy Resins are not suitable for the dishwasher and it is best to hand wash coated pieces only. For more detailed information on our epoxies and selecting the right resin for your specific project, we recommend using our Project Helper - it offers a comprehensive guide to resin characteristics and compatibilities.

Q: Why is my casting soft, malleable, or bendy after it has cured?

Soft, malleable, or bendy project is often due to improper mixing ratios (commonly too much hardener), insufficient curing time, or poor curing environment. Ensure the correct ratio of resin and hardener, mix thoroughly, and maintain a stable temperature around 23°C (73°F) with low humidity. Allow 24-48 hours for complete curing, depending on the product and conditions. If issues persist, check the product instructions or contact customer service for help.

Q: Why does my casting have wet/uncured resin on the bottom?

This issue usually comes from incomplete mixing or incorrect mixing ratios - commonly too much Part A. Its important to ensure to measure the resin and hardener as per the label directions, and mix thoroughly, scraping the container's sides and bottom. Environmental factors like temperature (20-25°C or 68-77°F) and low humidity are also crucial for proper curing. For more help, contact our support team at JustResin.

Q: Where can I install my Resin Art Project?

We suggest to install indoors, out of direct sunlight, and not in damp areas

Question 3

I want to create a Resin River Table with timber, which resin is best?

Accepted Answer

For this application, we suggest our ArtCast Slow Set or our RiverPour.
ArtCast Slow is designed for small casting applications and is ultra-clear, UV stable and super high strength, it can be poured up to 20mm deep (depending on surface area, and ambient temperature). However multiple pours can be completed to achieve greater depths.RiverPour Deep Pour epoxy is ideal for medium (3kg) to large (40kg) castings.RiverPour is a clear deep casting epoxy resin system that has been designed specifically for River Tables. A single pour can cast up to 50mm deep at 25c, with a pot life of 4 hours which will allow a lot of time for preparation and degassing if needed. Pours of up to 50mm deep (2inch) at 25C can be conducted without any fan assistance, however deeper pours can be achieved at a lower temperature and with fans.The key point of difference between the two is that RiverPour is specifically designed for medium to large River Table pours and is very slow curing with a 4hour pot life & >36hrs touch dry. 
Whilst ArtCast Slow is designed for smaller castings, it can be used for filling timber voids, although it does have a quick pot life of approx. 40mins and touch dry in <24hours.

Question 10

Where can I install my Resin Art Project?

Accepted Answer

We suggest to install indoors, out of direct sunlight, and not in damp areas

Question 11

Can I turn your Casting Resins on a lathe?

Accepted Answer

Yes, absolutely! We do suggest to allow a 7day cure prior to turning and or sanding

Question 12

Can I sand your Casting Resins?

Accepted Answer

Yes, all of our resins can be sanded back, and then polished - with finishing & polishing compounds. Micro mesh is great too.

Question 13

How should I mix/stir my Resin?

Accepted Answer

Pour the resin and hardener together and stir thoroughly for 3-5 minutes until combined throughout (no stringy bits).
Scrape the walls and base of the mixing vessel as you mix. Remember that a lot of material often sticks to the sides of the mixing container and even the mixing stick.
When your resin is measured correctly and mixed, you can now use your epoxy resin.
Use the next 35-45 minutes (note that work time depends on the specific epoxy resin you are working with) to spread the resin on your chosen surface. Or into a mould and remove the bubbles. This time-frame is your working allowance before the mixture starts to cure and thicken. Ensure you have adequate working time to apply the resin properly.

For detailed mixing & measuring steps, see our Step-by-Step Guide.

Question 19

Why do some ArtCast bottles arrive not completely full?

Accepted Answer

When purchasing ArtCast, the bottles may arrive not full, and details can be found on the product description.
To keep costs down, we have set size bottles available to us, and they are filled accordingly to the kit purchased.
For a 400ml ArtCast Slow Kit >
Part A : 300mls (in a 500ml bottle)
Part B : 100mls (in a 250ml bottle)
Total kit : 400mls

You may weigh the bottles to double check, if any further issues, please let us know :)

Question 20

Why do I have either Resin or Hardener left over?

Accepted Answer

We realise that it's hard to extract every last drop from the bottles, and due to this, we take it in our stride to provide you with up to 10% more of Part A up to 5% more of Part B, although it could be more

Question 21

What's the best tape to use?

Accepted Answer

We find 3M blue painters tape to be of great assistance when taping up edges and/or underneath the artwork

Accepted Answer

Most certainly!
You receive Resin (Part A) + Hardener (Part B)

Question 24

Can I pour a second, third, fourth layer on my Resin Art?

Accepted Answer

Of course, you can! Sanding is not required either. Your next layer may be a clear, a transparent layer, a clear & pigmented layer or a complete pigmented layer (in case you didn't like your first layer) - options are up to your imagination!

Question 25

Can I add water to my Resin as I do with flow/pouring medium?

Accepted Answer

No! Water & Resin are not friends

Question 26

Why has Part A gone cloudy in the bottle?

Accepted Answer

This can occur when the Resin is exposed to cold temperatures, even during transit.
You can fix this by placing some hot water in a bucket. Place the closed bottles into the bucket, keeping the lid on, and lid above the water - ensuring water does not leak in. Leave for approx 10 minutes, dry, give a good shake, and allow for the resin to return back to normal room temperature prior to use.

Question 27

What are some possible causes of Resin going hard in the cup?

Accepted Answer

1. More than 10% ink/pigment/acrylic paint to Resin ratio used
*Making note that some acrylic paints or pigment additives may not be compatible and may accelerate curing due to high water content
2. Too much Part B, measuring is to be precise
3. Room being too warm, 22-25degrees is ideal
4. Leaving mixed Resin in a confined space (eg cup, jug) will accelerate curing and could encounter aggressive exothermic reaction

Question 28

How long should I wait till I sand my Resin Art project?

Accepted Answer

We suggest allowing a full cure of approx. 7days, prior to sanding.

Question 29

How long should I wait till I pack & send my Resin Art?

Accepted Answer

We suggest allowing a full cure of approx. 7 days, prior to packing and shipping

Question 30

When packing my artwork for shipping, should I use bubble wrap?

Accepted Answer

We recommend not to use bubble wrap as the first layer, as it may leave marks/indentations in your artwork. Best to use a flat foam of approx 2mm thickness, wrap the piece with the foam, and then wrap with bubble wrap. Depending on the size of your artwork, you may be able to purchase cartons online or you can always makeshift a box! Use lots of filament tape & fragile tape too

Question 31

Why is my artwork still sticky/tacky after 24hours?

Accepted Answer

Firstly, it does depend on the epoxy resin you are working with, some cure slower than others.

Generally speaking, a coating epoxy will at least be touch dry at 24hrs - if its not, it can come down to a few causes...
- Room temp not ideal
- Incorrect Resin mixing or mis-measuring
- Too much tint or pigment incompatible with your epoxy 
- Adding anything out of the ordinary, outside pigments designed for use with resin.

Be sure to mix your Resin thoroughly, until you have a clear consistency throughout, no stringy bits at all & paying attention to the sides & bottom of the cup!

Question 32

Is Resin Art easy?

Accepted Answer

Resin Art is loads of fun & with lots of practice, experimentation and knowledge of the products you are using - it will become second nature to you

Question 33

Why do I have pitting/dimples on my artwork?

Accepted Answer

There are many variables that can assist with this being the outcome, generally speaking contamination, overheating or too thin of a coat of Resin will cause this.

Question 34

What steps should I take to clear coat my Acrylic Pours?

Accepted Answer

For clear coats over acrylic pours, here are steps that may assist:
1. Allow the acrylic pour to dry for at least 1 week, must be completely dry
2. If silicone, or silicone like substances have been used, clean away the silicone thoroughly with isopropyl alcohol and a cloth (test in a small section to ensure it does not ruin the painting) - allow to dry
3. Use a spray varnish or mod podge to seal the acrylic pour, and allow to completely dry
4. Pour the clear coat, gently heat, allow to cure (7days for a full cure).
 
Note - Taping up edges for clear coats can assist, and remove the tape when the resin becomes tacky, usually at approx. the 40min mark however this does depend on ambient temperature, and viscosity of the resin.

Question 35

What does viscosity mean?

Accepted Answer

Viscosity refers to the thickness of the product - low meaning thinner (ie. water), and high meaning thicker (ie. honey)

Question 36

Will my Home Decor item scratch?

Accepted Answer

We suggest to care for them like any other piece of Art. However being wear & tear items, over time and repeated use, micro scratches may appear on your Home Decor items

Question 37

How do I care for my artwork?

Accepted Answer

Dust with a soft feather duster or soft cloth - avoid detergents

Question 38

Why do I have either Resin or Hardener left over?

Accepted Answer

We realise that it's hard to extract every last drop from the bottles, and due to this, we take it in our stride to provide you with up to 10% more of Part A & EX and up to 5% more of Part B, although it could be more

Question 39

How long should I wait till I place items on top of my Cured Resin Art?

Accepted Answer

Generally speaking, a very minimum of 7days - however the longer you leave it, the harder the finish

Question 40

What is the ideal temperature my studio should be before I begin pouring?

Accepted Answer

Between 22 and 25 degrees Celsius

Question 41

What safety precautions should I be taking whilst creating Resin Art?

Accepted Answer

Be sure to always follow safety instructions & labels, for each product you are using, no matter the brand or product.

Question 42

How do I apply a clear coat?

Accepted Answer

Ensure surface is completely level & clean, pour a thick even coat, remove air bubbles gently with heat and allow to cure

Question 43

How long should I wait till I flip my artwork over & sand?

Accepted Answer

Always best to allow 7days to cure prior to flipping over and sanding

Question 44

How do you remove the drips from the rear of your paintings?

Accepted Answer

Options are giving the backs a sand once fully cured, use a popstick under the edges as its curing to wipe away the drips, or use painters tape underneath and remove the following day - whichever works best for you.
Alternatively, you could use Petroleum Jelly, however we personally prefer not to - As, in the case of it touching where your Resin is meant to go, your resin is going to repel & it's not going to adhere! (Not fun mid pour!!)
It's recommonended to use a mask & goggles whilst completing the task of sanding.

Question 45

How long should I wait till I pack & send my Resin Art?

Accepted Answer

Its always best to allow a minimum of 7-14 days to cure.

Question 46

Does humidity affect the finish of Resin Art during curing stages?

Accepted Answer

Yes, high humidity can affect the finish, we recommend to pour during temperatures between 22-25 degrees Celsius and not whilst  high humidity is being experienced for optimum results

Question 47

Why do I need to use a torch or heat gun when creating my Resin Art?

Accepted Answer

To remove micro air bubbles and pin point areas for movement - be sure not to burn the Resin!! We suggest to gently heat in continuous sweeping motions, keeping in mind to not be too close or hold in one spot for too long
