Featuring a 67-foot roll length and 40 mil thickness, it offers high adhesion and flexibility with a rubberized asphalt adhesive that resists cracking and drying. Compatible with a wide range of substrates, it provides reliable protection against wind-driven rain and ice dams, backed by a 10-year limited warranty. ## Description The MFM Wind and Water Seal is a self-adhering roof underlayment with a non-slip polymer film. It has a high-temperature, rubberized asphalt adhesive that will not crack or dry while remaining protected by a split release film that is removed once the underlayment is installed. Make sure to install Wind and Water Seal underlayment with proper ventilation, because it is considered to be a vapor barrier. Wind and Water Seal is compatible with most sealants and primers and can be applied to plywood, OSB, foam insulation, house-wrap, rigid vinyl, and masonry, as long as the surface is clean and dry before application. This particular underlayment is ideal for protection against ice dams or weather conditions such as wind-driven rain because of its reliable, uniform thickness. It is recommended to apply this underlayment in temperatures over 50Β° F on decks that have a minimum slope of 3:12. This protective barrier is most effective when stored out of direct sunlight. Once applied, Wind and Water Seal must be covered within 60 days of the installation. MFM backs the Wind and Water Seal with a 10-year limited warranty. High elongation, flexible, and accommodates to the contraction and expansion of the application surface The minimum slope is 2in. per foot for installation. Self seals around fasteners. Overlapping guidelines for easy installation.
