APPLICATION AND USAGE AMOUNT*

For bare, uncoated roofs use 1.5 Gal of CRS Waterproofing Primer Per 100 Sq. Ft and let it dry for up to 48 hours before applying CRS Silicone topcoat.

• Use 2 Gal. per 100 Sq. Ft. of CRS Silicone topcoat on previously primed or coated roofs.*

1. Prepare surface for CRS Silicone application by pressure washing and cleaning surface .
2. Reinforce any suspect areas such as seams and dripedge (cap sheet), seams and penetrations (metal), and keyways (shingles) with CRS Mastic
reinforcing fabric, or self-adhesive roofing tape as needed.
3. Primer surface with the proper high-grade primer such as CRS Waterproof Primer, NXT GP Primer, or NXT Metal Prime.
4. Apply CRS Silicone as one thick coat over clean, primered roof surface. Coating surface must be completely dry or problems with adhesion or
delaminating may occur.
5. Use all contents within one day of opening.
*Usage amount will vary depending upon how old or dry the roofs are.

Mixing and Storing Procedures
No thinning or reducing is necessary. Product may separate over time. Use a power mixer or paint stick to quickly stir coating before use. Containers are packaged to keep latent moisture from prematurely starting the curing process. It is highly recommended to use entire container once opened, but if storage is needed, reseal with a layer of mineral spirits or dry nitrogen.
