CastorCrete® SL

CastorCrete® SL

APF CastorCrete® SL is a gauge rake and trowel-applied cementitious polyurethane slurry, installed at 1/8-inch (3.18 mm)to1/4-inch (6.35 mm) to protect concrete from extreme physical and chemical abuse. It is resistant to impact and abrasion and stands up to steel wheeled cart traffic. It is unaffected by hot cooking oils, animal fats, and common solvents. APF CastorCrete® SL has been formulated to compensate for the difference in the coefficient of thermal expansion of concrete and will resist constant service temperatures up to 200°F (93°C). APF CastorCrete® SL can be purchased with an anti-microbial additive to inhibit the growth of fungi and other micro-organisms.

APF CastorCrete SL is an environmentally friendly product, made with natural, sustainable raw materials. It contains low VOC. APF CastorCrete SL is applied 1/8- to 1/4-inch (3.2 to 6.3mm).

APF CastorCrete SL may be applied to green concrete (7 - 10 days @ 70ºF) and concrete substrates indicating 100% moisture (ASTM F2170).

APF CastorCrete SL is a rapid turnaround flooring solution to minimize downtime. APF CastorCrete SL is installed as a one-step system without a primer and returned to service quickly after installation. APF CastorCrete SL may be top coated with APF CastorCrete TC or TC Aliphatic, a cementitious polyurethane top coat to create uniformity of performance and appearance. APF CastorCrete SL may also be top coated with APF POLYASPARTIC 7500, POLYUREA 5100, EPOXY 600 or 900 for enhanced chemical, abrasion, and UV resistance.
