Kool Seal Elastomeric Primer is formulated with a specialized acrylic latex polyer that forms an elastomeric sealant. It is designed to perform on troublesome roof surfaces and ponded water situations. It is recommended for use on rolled roofing, bonded tar and gravel, BUR, modified bitumen and most asphaltic surfaces. It is not required or recommended for metal or coated metal roofs. The rubber-like properties that allow expansion and contraction with the roof provide an excellent surface for application of Kool Seal Premium White Elastomeric Roof Coating (63-600) or Kool Seal White Elastomeric Roof Coating (63-300).

This product is a rubberized undercoating primer and MUST BE TOPCOATED. This primer is light grey in color and is designed to improve the adhesion of elastomeric roof coatings on troublesome surfaces. Do not use on roofs with a slope of 1/2" or less per foot. Do not apply when the temperature is below 50°F or is expected to drop below 50°F before the coating has completely dried.

Choose from a 1 gallon container.
