SP-888 is a copolymer emulsion designed for use with S-2200. SP-888 seals the substrate and improves the bond strength of S-2200 to substrates. SP-888 is supplied at a high solids ratio and is diluted 1:1 (by vol.) with clean water at the job site. SP-888 is low foaming, non-toxic, non-flammable and easy to apply. SP-888 meets or exceeds ASTM 1059 requirements for Type I or Type II Latex Bonding Agent. SP-888 is recommended for use with S-2200 to seal substrate and improve bond strength of S-2200 self-leveling underlayment to various substrates, concrete, brick pavers, ceramic tile and exterior grade plywood.
