Guidelines for roof restoration and application of fluid-applied, seamless roof coating system on concrete roofing.
Concrete is porous and will absorb water. Common problems such as crazing, scaling or spalling can cause roof leaks and rebar corrosion. Concrete slabs store the sun's heat during the day and release it into the building at night. High-performance, fully reinforced elastomeric roof coatings systems from Lexis will provide unparalleled thermal and moisture protection.
Bare concrete can absorb moisture and cause adhesion issues with newly installed coatings. Lexis recommends protecting the slab by applying a primer or basecoat whenever there is a chance of rain.
Our most popular system gives you the great adhesion and tensile strength of polyurethane plus the ponding and UV resistance of silicone. No primer needed.
Solvent-based, silver polyurethane roof coating with 300% elongation and 70% solids. Base coat and primer in one for flat roofs.
Solvent-based, silicone roof coating with 267% elongation and 69% solids. Stands up to permanent ponding water conditions.
Low-VOC system suitable for projects located in California. It uses a 2 component epoxy primer as an adhesion promoter and a high solid silicone roof coating.
Water-based, two component epoxy primer provides superior anchorage of silicone roof coatings on difficult substrates.
Solvent-based, silicone roof coating with 190% elongation and 97% solids. Stands up to long-term ponding water conditions. California VOC Compliant.
