A single component, solvent based, V.O.C. compliant sealer used as the first prime coat over unpolished concrete countertops such as the Ashby System. Penetrates to achieve a superior bond and pops the colors of the concrete to help create a natural stone appearance. Mix 1 to 1 with Acetone and apply three thin coats minimum (15 minutes apart) before grouting using an electric cup gun sprayer. Apply 2 coats minimum after grouting to seal the grout before applying CounterSeal 2. Ashby Super Seal is another option that can be used as a primer in place of CounterSeal 1 and 2. CounterSeal 3 can be applied directly over Super Seal.
