PERMASEAM™

PERMASEAM™ Metal Roof Lap Sealant is a white, elastomeric acrylic, nylon and fiberglass fibered, waterproofing adhesive, Liquid Seam Sealer and Primer. A waterborne, latex based, high resin content formula that contains minimal fillers and pigments. Designed as an easy to apply labor saving quick seam sealer on metal roof panel seams but can be used on most any type of roof seam. Nylon stranded fibers and fiberglass impregnated into the dried resin rich sealer enables excellent strengthening and bridging of seams and any other surfaces to which it is applied. This product is not recommended to seal problem seams and seams with a high degree of flexing or any gaps exceeding 1/16 of an inch; please inquire about our PERMATAPE™ Polyester Waterproofing Seam Tape or PERMASTIK™ Butyl Tape Self-Adhering Waterproofing Seam Tape. PERMASEAM™ will bond, seal and waterproof most new or existing roofing surfaces.
PERMASEAM™ rejuvenates, revitalizes and strengthens the surface to which it is applied, helping to prevent cracking, efflorescence, spalling and segregation. The bond that is formed between PERMASEAM™ and any subsequent coatings eliminates any possibility of moisture under the finish coat thus extending the coating’s life considerably.

SURFACE PREPARATION:
For proper adhesion it is essential that the surface is prepared properly. Clean Exterior Surfaces by thoroughly pressure washing with a water and chlorine solution using at least 1500 P.S.I. to remove any previous coatings, dirt, grease, and other foreign materials, especially mold, mildew and algae. PERMASEAM™ will resist mildew growth but will not kill mildew already on the surface. Rinse thoroughly. Remove loose paint and powdery substances. Patch any holes, cracks, seams, imperfections, etc. that exceed 1/16 of an inch, with PERMAPATCH™, Waterproofing Caulk & Sealant.

Metal:
Clean surface of all grease, oil and foreign matter before priming. Rusted metal and uncoated metal must be primed with METAL-PRIME™, a Red Iron Oxide Primer Sealer. Use a degreaser on galvanized or coated metals which have oils or surface. treatments. Check PERMASEAM™ adhesion on galvanized or coated metal by applying to a small area and evaluating after 48 hours. If lack of adhesion is present after evaluating, metal must be lightly scuffed without penetrating the coated finish or galvanizing. If applicable, use METAL-PRIME™ to spot prime the penetrated areas, then use PERMASEAM™ for area to be coated.

APPLICATION PROCEDURE:
Stir well before using. Do not thin, use product as is. Do not apply when temperatures are below 45 degrees Fahrenheit or when humidity is very high. Do not apply when coating will be subjected to rain or heavy dew before it has had enough time to dry (approx. 2 to 4 hours). Drying time will vary depending on temperature, humidity and location. Apply using brush or roller. Spread primer uniformly sealing seam and surrounding areas. Spread Rate will vary depending on substrate. Apply PERMASEAM™ at least 16 mils wet film thickness. Check seams after application and apply additional coats if necessary. Wait at least 6 hours before applying additional coats or a compatible primer, paint or coating.

APPLICATION HINT:
Puncture pour holes in five-gallon pails and pour a liberal bead directly on seam and follow with roller to distribute to seam and surrounding areas.

CLEAN UP:
Clean up all spills, tools and overspray immediately while the coating is still wet with warm soapy water.
