SURFACE CONDITIONER F9910 (For single ply sheet rubber)
The weathering process combined with airborne dirt and pollutants creates a thin layer of deposits on all exposed surfaces. These deposits are difficult to remove and reduce the adhesion of paints and protective coatings. This Surface Conditioner is designed to stabilize these deposits on single ply sheet rubber and improve the adhesion of Liquid Rubber®. An improved bond will be more pronounced over newer and less weathered rubber as well as with older more weathered surfaces. Moderately weathered rubber will still benefit from the use of Surface Conditioner but to a lesser degree, since Liquid Rubber® generally develops better mechanical adhesion here thus masking the influence of the Conditioner.
EPDM sheet rubbers will absorb solvent from the Surface Conditioner and from Liquid Rubber. This will cause the rubber to swell, which may result in wrinkling or bubbling. This condition is temporary and the rubber will usually recover its original shape as the solvent slowly evaporates. Some older brands of rubber exhibit more pronounced swelling and may not recover completely. Potential problems can be avoided by first doing a small area as a test before coating the entire roof.
Clean single ply rubber by scrubbing surface with a detergent solution. Thoroughly rinse with water and let dry. Apply a thin coating of Surface Conditioner with a roller or bristle brush. Work a small area repeatedly until surface looks uniform without leaving any puddles before moving on. Solvent will evaporate quickly leaving a slightly tacky surface behind. Clean soles of shoes before walking on treated surface. Liquid Rubber® may be applied to treated surface immediately or days later if further dirt pick-up is prevented.
COVERAGE: 200 square feet per gallon on single ply sheet rubber.
