Henry Moistop Sealant 20 Fluid Ounce Sausage

Henry Moistop White Sealant is designed to make weatherization easier and to save you time on the jobsite. Henry Moistop Sealant is both a moisture-resistant sealant and a flashing. Henry Moistop Sealant is fully compatible with all of the Henry products. Henry Moistop Sealant delivers excellent adhesion and moisture resistance to a wide range of building materials, surfaces and structures. Henry Moistop Sealant also provides flexible, gap-free flashing even around curved intrusions and can fill construction joints up to ½ inch thick. As part of the Henry 1-2-3 moisture control system, Moistop Sealant is designed to withstand the rigors of the jobsite and the elements. Henry Moistop Sealant will adhere and perform in uncontaminated joints with most common construction substrates which include but are not limited to concrete, exterior gypsum, stucco, EIFS, aluminum, galvanized surfaces, glass, wood and polyvinyl chloride (PVC). Due to the vast numbers and types of surface coatings and treatments available, Henry recommends pretesting Moistop Sealant on the surface in question. Sealant compatibility testing is not required for Henry’s full line of flashing products and weather-resistive barriers. All surfaces should be clean and clear of any surface contamination. In the case of some exotic coatings, priming or other surface treatment may be necessary.
