Ponding Water
The Roofseal Silicone Top membrane is not affected by ponding water; however, the National Roofing Contractors Association considers ponding water on any roof undesirable and recommends that all roof systems be designed and built to ensure positive drainage. (See the NRCA Roofing and Waterproofing Manual).
Flammability Characteristics
Roofseal Silicone Top Coatings carry Class "A" Non-Combustible and Class "B" Combustible credentials as tested under UL 790 procedures over spray foam and single ply roofing systems. Contact Davlin Coatings or refer to the UL directory for specific information. Consult Davlin Coatings for any specific questions regarding the application of this product.

Application Equipment
- Application Equipment: This product may be sprayed, brushed, or rolled. Due to the high viscosity of the material, a high-pressure airless paint pump capable of producing a minimum of 3500 PSI at the spray gun head should be used. The pump should have a minimum of 3 gallons per minute output and be fed by a 5:1 transfer pump to prevent cavitation. Always use components rated for pump pressure. Hoses should be BUNA-N jacketed for prevention of moisture contamination. Hoses should have a minimum I.D. of 3/4" and an adequate working pressure. The spray gun should be high pressure (5000 PSI) with reverse-a-clean spray tip, having a minimum orifice of .030 and a 50° fan tip.
- DO NOT USE hose that has been used for Acrylics or other waterborne coatings because the liner absorbs moisture and initiates the silicone cure process.

Safety & Health
- Limitations
Product Limitations
Not recommended for continuous immersion service, for use in cryogenic tank, or cold storage roofing applications without a vapor barrier, or directly over modified bitumen, asphalt or coal tar built-up roofing systems without a sealer.
Weather Restrictions
It is not recommended that this product be applied at tem- peratures below 50* F (10° C), or if rain is expected within 1 hour of application. Roof- seal Silicone Top may be applied at lower temperatures, however the cure time will be extended.
