Hacker Industries, Inc. knows that one of the key jobs of a floor underlayment is to provide a substrate for your finished floor goods. This is why we have introduced a line of TopCoat and Sealer products, which will assist your floor covering installer to produce the best possible result.

Hacker Floor Primer is designed to enhance the bond between a FIRM-FILL Gypsum Concrete and existing structural substrate (wood, concrete, or existing floor coverings).

Hacker Floor Sealer is a clear, water based, vinyl acrylic co-polymer sealer that is recommended over Hacker Floor Underlayments (depending on the specified finished floor covering adhesive).

Hacker TopCoat® SP is an acrylic based, film-forming surface preparation agent designed to meet ASTM F2419-05 compliance requirements for use on Thick Poured Gypsum Concrete Underlayments specified to receive resilient floor coverings. When used in conjunction with Hacker floor underlayments, Hacker TopCoat® SP provides optimal surface bonding conditions for most floor covering adhesive products.
