Tremco’s SX302 – Moisture Tolerant Latex Underlayment
SX302 can be used prior to the application of a liquid applied dampproof membrane. It is a moisture tolerant, cement based, latex underlayment developed for use in domestic, light commercial and light industrial environments. With a compressive strength of 25 N/mm², SX302 can be applied using a hand trowel to spread with a maximum application thickness of 6mm on minimized adhesive residues and 10mm on sound substrates.
Tremco recommends thorough subfloor preparation before applying SX302. The surface should be free of contaminates such as oil, grease and laitance and any other contaminants and should be vacuumed or swept clean. For absorbent or porous surfaces, Tremco would recommend CS150 Acrylic primer or CS190 Gritty Primer, however, SX302 can be applied directly onto concrete or sand/cement screeds. The success of the system is dependent on the stability and bond of the underlayment to the substrate.
