Kool Roof

Premium White Elastomeric Roof Coating

DESCRIPTION: Kool Roof Bright White Elastomeric Coating is a premium grade, water-based, acrylic elastomeric, “rubber-like” roof coating. Kool Roof is non-toxic, non-hazardous, non-flmmable. When properly applied clean, dry, mechanically sound roof Kool Roof will provide years of water-tight protection.

Kool Roof is easily applied with brush, roller or airless spray equipment; it provides a highly protective barrier which will reflect the damaging heat and destructive UV rays from the sun. High solar reflectance can have a significant effect on reducing roof temperatures, which can lead to a reduction of interior temperatures.
SURFACE PREPARATION: All unnecessary and non-functional equipment must be removed from the roof. The substrate must be pressure washed prior to the application of Kool Roof. A minimum working pressure of 1,500 psi should be used to remove all dirt, dust and previous paints & coatings, which are delaminating. Thoroughly rinse roof surface after cleaning. TSP (trisodium phosphate), or appropriate cleaner, can be used along with a deck brush to clean the roof, after which the roof must be thoroughly rinsed with clean water. If the roof has an excess amount of oil or grease, a degreaser may be required and scrubbing with a deck brush may be needed. Rusted metal roofs must be wire brushed and primed with a metal primer/ sealer before Kool Roof is applied.
APPLICATION: First, make sure all repaired areas are sufficiently sealed and dry and that the primer has been applied evenly. Any deficiencies in the roof system must be corrected before proceeding. Choose the morning of a warm day to apply the Kool Roof. Apply with a 3/4" long nap exterior roller or medium bristle latex paint brush. Coating is to be applied in two coats. Ideally, second coat should be applied perpendicular to the first coat. Allow twenty-four hours between coats. Humidity and temperature will vary dry time. On a cool humid day, the dry time will be longer. Care should be used not to over roll or brush coating on to roof surface. DO NOT apply to surfaces with less than 1/2 inch per foot slope. DO NOT apply in a ponding water area. DO NOT apply to any areas where ponding water exists. This product can also be applied with airless spray equipment, 3,000 psi, 2 gpm with a .631 tip.

NOTE: If the roof becomes too hot (over 95F/ 35C) during application, it is recommended to delay further application until the next morning when surface temperatures are cooler. Excessive roof temperatures may cause blistering of the coating.
APPLICATION RATES: per coat (three coats required for warranty)
Metal 100 sq.ft./gal
Single-ply 100 sq.ft./gal

COLOR TINTING : Universal colorants can be used to tint coating to pastel and light colors. Tint to coating ratio is not to exceed 4 ounces of colorant per gallon. NOTE: Field tinting will void manufacturer's warranty.
PRECAUTIONS: Surface to be coated must be clean, dry and mechanically sound. The roof must have positive drainage, NO PONDING WATER AREAS. Roof surface temperatures must be between 50F - 90F (10C - 32C). DO NOT apply if heavy fog, dew or rain is expected within 24 - 48 hours of application. Do not applywithin4hoursofsunset. Lowtemperaturesandhumidity will increase dry times. DO NOT allow liquid coating to freeze. It is recommended that UV resistant sunglasses are used during application. When transporting product, care should be taken to assure that the lid is securely fastened to the bucket and that bucket is in an upright position. DO NOT heat sealed container or store where temperatures reach or exceed 120F (48C). Buckets are to be secured so that they do not roll or tumble over, which may cause a leak or other damage. Never transport full or partial buckets in vehicle where passengers are present. Bucket shifting can cause bodily harm. Not recommended for areas where foot traffic may occur.
