TotalBoat TableTop Epoxy can be applied directly over TotalBoat ThickSet Epoxy.
For instances where the ThickSet is newly poured and is firm but not fully cured to a hard material, TableTop Epoxy can be applied directly over it without any surface preparation.
For instances where the ThickSet has already cured to a hard material, the surface must be completely clean and have no possible surface contaminants. If there are any surface blemishes, they can be lightly sanded out with 220-grit sandpaper. Sanding the entire surface before applying TableTop Epoxy is not required, but will promote the best bond for the new layer of TableTop Epoxy.
