T2424 elastomeric roof coating is easy-to-apply and provides lasting protection that exceeds Title 24 “cool” roof requirements.
Use wire brush, steel wool or industrial paper to remove old paints, grease and/or rust from roof surface. On steel that is rusting, apply a metal primer first coat.
Using patching compound repair all leaks prior to applying roof coating. For larger openings use fiberglass tape. Be sure repaired surface is dry before applying roof coating.
Pressure wash and remove debris.
Repair seams and cracks using fiberglass or fiber mesh.
Allow surface to dry completely before applying coat. To improve weather and water resistance, use fiberglass or fiberglass mesh to entire surface area then apply roof coating.
Do not use on polyurethene foam roofing or roofs without proper pitch and drainage. Use brush or roll to apply two or more coats to clean and repaired roof surface. Do not apply below 50-degrees or to a damp surface. Do not apply when humidity is high.
Generously apply to prepared surface. Allow to dry and apply second coat. To improve adhesion of fiberglass mesh to surface, use roof coating as a primer or use an adhesive fiberglass mesh. See also elastomeric roof coating.
