Description

Calbar Roof Paints have been preserving and restoring metal roofs for almost 90 years. This is a unique product developed to withstand the harsh treatment that weather and ultra-violet degradation can inflict on a metal roof. It will not blister or peel and when applied correctly will be maintenance free for a minimum of ten years. Proper preparation is the key to success. Approximately 80% of all paint failures is due to improper surface preparation so this step should not be overlooked. Begin by power washing the entire surface with 3500 psi. Much of the old paint and rust will be removed. Using TSP (Tri-Sodium Phosphate) in the power washer or alone with a scrub brush will insure a very clean surface. Rinse the TSP thoroughly. For a metal roof that has been previously coated with an aluminum asphalt coating, much or all of it can be removed by hitting the metal surface with a 1 inch rubber hose. The asphalt will pop off of the roof, and the coating that is potentially damaging to your metal will be removed.After cleaning the roof, inspect for weak areas that can cause leaks such as flashing, seams, pin holes and fasteners. If these are defective, repair with CRS (Calbar Roof Seal) or CRS and Mesh. CRS is also an exceptional rust inhibitive primer, and can be used in place of the 10-520 primer for maximum rust protection. (See Step 1)
