Enhance the bond of underlayment to finished floor covering

GSL® All Purpose Sealer (APS) is recommended for use on all GSL® (family of products) installed systems to enhance the bond of underlayment to finished floor covering.

GSL All Purpose Sealer applied to surface of gypsum underlayment will eliminate any dusting creating a durable surface resistant to incidental moisture, resulting in an ideal surface for most floor coverings. One coat is all that is required, just mix at a 1 to 3 ratio with water and apply using approved methods.
