M620 SilvrMastic
Rubber Aluminum Mastic

USES: M620 SilvrMastic effectively seals around chimneys, vents, pipes, air conditioning equipment, skylights, drains, flashings, and sheet metal. SilvrMastic also repairs surface fissures, and stops leaking nail heads. SilvrMastic is compatible with SEBS, APP, and SBS modified bitumen roofing products and will adhere to most surfaces including roofing, wood, metal, glass, and concrete.

DIRECTIONS: M620 SilvrMastic is friendly to apply. Apply with a broad putty knife. Warm SilvrMastic to room temperature for easiest application. Do not apply SilvrMastic if rain is imminent either during or immediately following application. Clean gravel, dirt, vegetation, and debris from the application area. Make sure the application surface is smooth, firm, dry and frost-free. Apply directly from the container without diluting. Seal areas exposed to water penetration with SilvrMastic. Generously apply a minimum .5" thick layer of SilvrMastic over the exposed area. Make 3 layer repair with SilvrMastic and PolyWeb over fissures or to reinforce degraded areas. First trowel a generous application of SilvrMastic over the application area and beyond the width and length of the PolyWeb you intend to install. Second, lightly trowel the PolyWeb into the SilvrMastic. Third, carefully trowel a generous application of SilvrMastic over the entire repair, making sure to completely cover the PolyWeb. For severe fissures, apply additional layers of PolyWeb and SilvrMastic.

DESCRIPTION: M620 SilvrMastic is a quality rubber aluminum mastic. Select raw materials, including have been formulated to make SilvrMastic a premium aluminum mastic. SilvrMastic provides superior elastic performance against thermal shock, the daily expansion and contraction of a roof caused by temperature changes. In addition, the sun's UV rays attack the roof membrane making it brittle and weak, inducing membrane ruptures during thermal shock cycles. SilvrMastic is your best defense against these attacks. With SilvrMastic, your roofing installations will perform much longer. SilvrMastic is asbestos free.
