Silencure SRT, Acrylic Curing & Sealing Compound with Silane

ChemMasters’ Silencure Solvent Replacement Technology—SRT is a patented pure acrylic copolymer curing and sealing compound for new concrete installations. When applied to fresh concrete Silencure SRT produces a non yellowing clear continuous film that effectively cures fresh concrete and provides a tough protective acrylic film.

Silencure SRT’s unique technology forms an effective curing and sealing film with a proprietary blend of siloxanes that penetrate capillary pores of fresh concrete forming a silicone matrix within the concrete preventing water and salt penetration.

Unlike other silane or siloxane treatments Silencure SRT is applied to fresh concrete curing to ASTM C 309 and AASHTO M-48, Type 1 & 1D, Class A&B and is designed to meet most State D.O.T. Requirements for NCHRP 244, Series II & Series IV water absorption and chloride protection. There is no need to wait 28 days before applying a product for long term protection.

Application:

For Best Results: Do not apply Silencure SRT if the temperature will drop below 50°F within two hours of application. Protect people, vehicles, property, plants, windows, and all non masonry surfaces from product splash, residue, fumes, and wind drift.

Apply Silencure SRT after all bleed water has dissipated and within 2 hours of final finish. Applying Silencure SRT after two
hours may result in poor penetration and lead to blotchiness, blistering and peeling. Do not apply over free standing water.
Apply Silencure SRT with a low pressure, airless, sprayer equipped with a fan nozzle 0.50 to 1.0 gpm or a hand pressurized sprayer with a ‘Cats Eye’ nozzle. ensure spray equipment is clean and dry before adding Silencure SRT.

The optimum spray pattern is an 8 to 12” fan. Hold sprayer tip 8 to 12” from the surface of concrete. Apply uniformly leaving no pinholes or gaps. Do not allow material to puddle. Silencure SRT may be applied with a short nap roller when application will not mar surface and will be complete within 2 hours of final finish.
