If your epoxy pour is too thick, the reaction can create too much heat, resulting in a product that does not cure properly with cracks or excessive bubbles. The rule of thumb is if you can make an imprint with your fingernail in the epoxy you can pour again and the epoxy will chemically bond to the previous layer.
How thick can epoxy be poured?
As long as you pour in 1/8″ layers, you can go as thick as you like. The reason we recommend this thickness is two-fold: first, it allows the bubbles to escape properly, and second, it avoids any excessive overheating of the resin. So for best results always pour in a 1/8″ layer, and you’re good to go!Feb 6, 2021.
Can you pour epoxy 2 inches thick?
Our Deep Pour Epoxy Resin is not made for coating or thin layers. Deep Pour Resin is made for casting half an inch to 2 inches deep. We recommend pouring a minimum of 1/2 inch depth up to 2 inch depth when working with Deep Pour Resin.
Will thick epoxy cure?
Generally, epoxy cures faster when the air temperature is warmer. Exothermic heat is produced by the chemical reaction that cures epoxy. In a thicker mass, more heat is retained, causing a faster reaction and more heat. The mixing container’s shape and the mixed quantity have a great effect on this exothermic reaction.
How thick can you pour West System epoxy?
While it is a slower curing system, it still should not be poured more than ¼” deep at a time. We have found that building up castings ¼” at a time allows the epoxy to cure without overheating.
How many square feet will a gallon of epoxy cover?

Why is my resin thick?
Temperature If it’s colder than that, the resin will be thicker and harder to mix, will have more bubbles and will take longer to cure until it’s dry to the touch.
What is considered a deep pour epoxy?
With the ability to pour the resin between 2-4 inches deep you are guaranteed a solid finish that won’t warp when exposed to heat or moisture. The depth of the pour also protects it from breakage, and guarantees a solid, non-flex shape.
Why is epoxy not hardening?
If your epoxy resin hasn’t cured properly, this means that the chemical reaction between the resin and hardener was not able to take place. Sticky resin is typically caused by inaccurate measuring or under mixing. Try moving your piece to a warmer spot: if it doesn’t dry, re-pour with a fresh coat of resin.
How do you fix sticky epoxy?
How to easily fix sticky Resin Recoat: Add another fresh layer of doming resin on top of the sticky spots. Move your artwork into a warmer spot for 24 and let it dry ( resin drying time 20-24 hours ). Sand the entiry sticky surface off with 80-grit sandpaper and pour another resin coat layer.
Why is my UV resin still sticky after curing?
Like most UV resins it’ll be tacky after only curing for a few minutes. That’s normal since UV resins harden fast but take some time to fully cure. It’s because it’s overheating while curing. Doing it in thin layers or curing it slowly (weak light) will greatly reduce this problem.
What should you not put in resin?
Paper, plastic, fabric, metal, clay, wood, natural elements, glitters and powders, and any combination of these elements work well. Things that contain moisture should be avoided, for example, fresh flowers and leaves. The water will react with the resin, turning the leaves and petals brown.
How do you seal wood before epoxy?
Simply coat the wood with a thin layer of wood epoxy resin and allow to cure. This will provide an adequate seal before you add more epoxy resin for wood.
How good is West System epoxy?
5.0 out of 5 stars This is one of the BEST EPOXY SYSTEMS on the market. Excellent Resin when mixed with West System 205 Hardner. They also make other hardeners with different cure times , for different applications.
Will epoxy set in cold weather?
Some resin/hardener combinations are formulated to cure in temperatures as low as 35°F. However, simply using a hardener that cures in colder temperatures does not guarantee dependable bonds. Epoxy can be used at cold temperatures but must be handled and applied with techniques adapted to cold temperatures.

Can you pour epoxy over cured epoxy?
Can I put another coat of epoxy over cured epoxy? Yes. Since the epoxy has cured a chemical bond is not possible so what is called a mechanical bond is needed. This simply means that the cured epoxy has to be lightly sanded before the next coat is applied: the first coat should have a matt, almost white, surface.
How long should you wait between coats of epoxy?
When using epoxy, it can be a helpful process to add a second layer, but you want to make sure to follow the correct procedures. With most coating epoxies, if you are trying to build up to your desired thickness, it is recommended to pour your second coat once the first coat is tacky to the touch (usually 4-6 hours).
Should I sand between coats of epoxy?
Sanding will not only get out the imperfection but will also serve to provide some tooth between the first and second layers. It will look very scuffed in the short term but do not worry, once you pour the second coat over top, all of those sanding marks will disappear.
