Hacker Floor Underlayments
Product Benefits: Abrasion Resistant

We know how important it is not to rub your underlayment the wrong way

This is why we developed Hacker TopCoat and branded sealers specifically for use in conjunction with poured gypsum underlayments, including FIRM-FILL Gypsum Concretes and GYP-SPAN Radiant. Applied after the gypsum concrete underlayment is completely dry, the Hacker TopCoat or sealer improves the abrasion resistance of the underlayment, providing a durable surface ideal for virtually any finished floor covering
