After thoroughly mixing the resin and hardener then pour your epoxy resin into your mold at the recommended depth of 1/8 to 1/4 inch. At this depth it may require multiple pours to reach your desired depth. We recommend pouring each layer at 1/8 to 1/4 inch then applying a bubble release technique (see details below) then let the resin cure for 4 to 5 hours before pouring the next layer.
Repeat the process and the bubble removing technique on each layer until you reach the desired depth. This method may require patience but will achieve a gorgeous crystal clear finish. Each layer will bond to the previous layer and will have a seamless appearance. It will also achieve perfect casting when adding pigments. Make sure it is upright and level during the entire process.
Tips for Releasing Bubbles-Various Bubble Removing Techniques
1. You can use a propane torch 4 to 6 inches away from the mold in a quick waving motion. (the torch will be far enough away to release the bubbles without effecting the silicone mold with heat)
2. You can use a small barbecue lighter quickly over the surface to release bubbles.
3.You can use a heat gun very quickly and carefully over the mold but from a distance because the heat gun produces a lot of high heat. Don’t leave it too long or it could melt the silicone mold.
4. You can lightly blow air on your mold at a distance through a straw that is at least 3 inches from your mold to release bubbles.(make sure to only blow out through the straw and that it is a safe distance from the resin)
5.Heat up the end of a screwdriver with a lighter until it is very warm then put the warm screwdriver into the resin where the bubbles are and move it around. The heat will help release the bubbles.
Note: It’s a good idea to keep on eye on your project and use the bubble removing technique for up to an hour after pouring in case any additional bubbles surface.
