SG-40 is a modified acrylic base roofing coat that's an alternative to asphalt emulsion roof primers. SG-40 locks onto the existing roof system providing exceptional resistance to blistering - even under prolonged ponded water conditions. The technology used in SG-40 produces a coating that offers excellent adhesion to a variety of roof substrates in use today: granulated cap sheet, metal roofs, polyurethane foam roofs and single-ply roofs found on older buildings. Combined with specguard's SG-54 topcoat product, SG-40 offers complete system continuity providing a uniform roof system that won't peel or blister under the most demanding conditions.
