Product Information Sheet
A460 AtcoStop
All Weather Damproof Coating

USES: A460 AtcoStop protects surfaces exposed to the weather. AtcoStop is an excellent protective coating for foundations, gutters, concrete, metal, and wood. It can also be used over corrugated metal, metal flashings, and equipment to prevent rust and corrosion. AtcoStop will adhere to most surfaces including wood, metal, rubber, plastic, glass, and concrete.

DIRECTIONS: A460 AtcoStop is friendly to apply, even in cool to moderate temperatures. Warm AtcoStop to room temperature for easiest application. Clean away all dirt, vegetation, and debris from the application area. Severely rusted areas shall be cleaned of all loose rust, primed with zinc chromate or red lead, and allowed to dry before applying AtcoStop. Applications over newly poured masonry shall be done after complete drying to prevent water blisters. Use a medium stiff bristle brush or asphalt cutback spray equipment to apply AtcoStop directly from the container, without diluting. AtcoStop applies as a smooth paint-like consistency. To apply a protective coating with AtcoStop, first seal any leaking penetrations and repair all surface breaks with M300 RubrMastic. Then, generously apply AtcoStop at the rate of 3 gallons per 100 square feet. For maximum protection and reduced energy costs, apply M800 RubrStar over the AtcoStop. Allow the AtcoStop a minimum of 90 days to set up before applying the RubrStar.

DESCRIPTION: A460 AtcoStop is a leading edge cutback foundations coating manufactured from 100% oxidized asphalt. AtcoStop forms a waterproof surface and provides good weather protection over metal and masonry surfaces. Its excellent penetrating qualities eliminate the need for priming. AtcoStop 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. AtcoStop is your best defense against these attacks. With AtcoStop, your waterproofing installations will perform much longer. AtcoStop has an Underwriters Laboratories (UL) Class A Fire Rating. AtcoStop is asbestos free.

SPECIFICATIONS: A460 AtcoStop exceeds the standards of the American Society for Testing and Materials ASTM D 3019, Type I, Grade 1. Maximum VOC is 300 grams per liter.

PACKAGING: A460 AtcoStop is available in 5 gallon pails.
