Styro-Roc Hard Coat Finish for EPS Foam
Styro-Roc is a simple to apply hard coating for various types of rigid foam. It is a premix coating, which can be hand brushed, rolled or sprayed with ordinary painting equipment such as a hopper gun or a pressure pot sprayer. It provides a strong, lightweight uniformly smooth appearance, which can be coated with any type of solvent or water base paint.
Styro-Roc
can be used to coat wet-cast concrete molds carved from EPS foam. It seals and
waterproofs hot wire cut or carved EPS foam shapes for outdoor installations.
This product provides a 15-20-minute working life after mixing the A and B
components and an unlimited pot life when using the pressure pot sprayer.
Styro-Roc is dry to touch within 30 minutes, and full-cure is achieved after
48 hours at 72 degrees Fahrenheit. The viscosity of this material should not be
reduced.
Styro-Roc is a replacement for 2 component plural application hard coating products, which require the use of expensive high pressure spraying equipment.
