Great question. MAS Table Top Pro should not be applied thicker than 1/8” - 1/4” per coat. Deeper coatings can be achieved by step pouring multiple layers. Exceeding max coating thickness may cause MAS Table Top to heat up and exotherm upon hardening which could cause it to yellow, distort or even crack in extreme cases. Each layer MUST be allowed to cool to room temperature (70-80°F) before over coating or adding additional layers. Once cooled, you can pour the next layer without additional surface prep all the way up until you can no longer indent a fingernail into the previous coat. No sanding necessary. That should be around 2-4 hours after pouring, but warmer temperatures will set faster, and cooler temperatures will set slower. Large batches of mixed epoxy will also cure much more quickly than small batches. If allowed to cure past the point of being able to indent a fingernail, then you will want to lightly scuff sand between coats to promote adhesion. As a general rule, if you can sand, you should. Be sure to clear away any sanding debris with a clean cotton rag and an oil free solvent like denatured alcohol before your next pour.
