Enhances the adhesion of PS #220 and PS #250 silicone roof coatings to galvanized steel, aluminum, granulated modified bitumen membranes, wood and masonry. Excellent Alkali resistance. Rain resistant after 3 hours. Contact KM Coatings Technical Services for clarification of unusual surfaces or project conditions.
- Application Instructions
Surface Preparation:
All surfaces to receive coating must be clean, dry and free from any foreign matter such as dirt, oils, grease or other debris that could inhibit the adhesion capabilities of the newly installed products. Metal surfaces that display rusting or other oxidation, to be prepared with a grinder or wire brush as needed to remove surface contaminants. Existing roof systems to be visually inspected for conditions that may adversely affect adhesion or performance of newly installed products. Repair any visible deficiencies such as splitting blistering and buckling with KM Acrylicaulk, KM Brush-It Acrylicaulk or KM1213 Elastomeric Mastic and Prime Polymesh or T272. Visually inspect all metal and non-metal flashings, edges, drains, valleys and through-roof penetrations and repair as needed by project conditions. Do not apply to wet or visibly damp surfaces, surfaces previously covered with coal tar based products or Kynar® finishes. Concrete surfaces cured with wax/resin based compounds can inhibit adhesion.
Application:
Mix well prior to application.
Application rates vary:Galvanized Steel 1⁄2 gallon per squareAluminum 1⁄2 gallon per squareBituminous, granulated membranes 2⁄3 – 1 gallon per squareWood 1⁄2 – 2⁄3 gallon per squareConcrete / Masonry 1⁄2 – 2⁄3 gallon per squareKM 1P may be applied by high pressure spray equipment. Smaller work areas can be accomplished with medium nap roller or a brush. Product which is applied heavier than recommended will affect performance detrimentally. To improve adhesion, allow to dry for 12 hours. Drying times will vary depending on application rate, porosity of surface, temperature and humidity. Maximum wait time for initial application is 72 hours. Do not apply if there is a threat of inclement weather or contaminates that would affect adhesion of subsequent products. If product is rained on after the allowable 3 hours, let dry prior to applying silicone. Minimum application temperature is 45°F as long as this is 5°F above the dew point. Maximum application temperature is 120°F.
- Spray Equipment
KM 1P can be applied by conventional airless spray equipment designed for the purpose of field application of fluids, paints and coatings. Back rolling the primer/bleed blocker is required when the product is sprayed. The following minimums are recommended:
Pump: 1.6 gal/min output; 2,500 psi
Gun/Tip: Airless hand gun. Reversible tip with orifice sizes ranging from 0.19—0.25 and a fan angle of 40° or 50°.
Hose: Minimum inside diameter of high pressure nylon hose of 3⁄8" to 100'; for any hose over 200’ the inside diameter should be 1⁄2".
Refer to equipment manufacturer product guidelines.
