The maximum depth to pour is approximately 1/8”- 1/4" thick. If depths thicker than 1/8”- 1/4" are desired, multiple coats are necessary. You must wait at least 4 to 10 hours between coats to allow sufficient curing and cooling. Attempting to pour thicker can cause the epoxy to generate excessive heat which in turn will cause more air bubbles, possibly cracking and shrinkage. You will be able to pour up to unlimited depths if you follow the instructions.
