Installation

Thoroughly mix the coating before application. All surfaces must be dry and free of dirt, debris, algae, mildew, oil, talc, loose granules or any other foreign matter that may prohibit adhesion. Power-washing and/or priming surfaces may be necessary to enhance adhesion or limit asphalt bleed-through. ALSAN COATING SIL 402 can be applied using a brush, roller or airless spray equipment. ALSAN COATING SIL 402 is intended for use as a direct-bond, single-pass silicone roof coating. Apply at a minimum rate of 1.5 gallons per 100 square feet for a minimum dry film thickness (DFT) of 22 mils. Application rates vary by project and warranty, please consult the Roof Coatings Technical Manual for full list of coverage rates and warranties. NOTE: ALSAN COATING SIL 402 is a moisture cure product. Once containers are open and exposed to the air, a skin will form on the material, which must be removed before use.

Please refer to the SOPREMA Roof Coatings Technical Manual for additional application guidelines.

Denver Union Station – Denver, Colorado

When the Denver Union Station was to go through a remodel, SOPREMA’s COLPHENE® BSW product was selected to waterproof the building.
In 2011, SOPREMA met the challenges of waterproofing the building envelope with the COLPHENE BSW system to ensure a seamless watertight solution. Over 170,000 sq ft of COLPHENE BSW was used as a waterproofing membrane.

Parkland Hospital – Dallas, Texas

The new hospital featured flat rooftops at multiple levels that all needed to be made watertight for decades to come. The roofing system needed to be designed in a way that accounted for a helipad, consistent rooftop traffic, extensive rooftop equipment, lightwells and various utility platforms. A lot stood in the way of Anchor Roofing, the installer, but the meticulous planning for the project meant that all contingencies had been considered by the time application of the waterproofing system began.
