Description: Bostik Webpatch® 90 is a fast-setting, gypsum-based material designed for interior installations and may be used to patch floors, walls and other surfaces. Floor covering can be installed after just 1 hour from patch application. Bostik Webpatch 90 may be used to fill up to 1/2” deep over properly prepared concrete, masonry, cementitious backer board and structurally sound exterior grade plywood (interior/dry use only). When used properly, this product provides a fast-setting surface that will not check, crack or break up. The Webpatch 90 may be mixed with Bostik 425™ Multi-Purpose Acrylic Latex Admixture instead of water for improved performance.Information provided by Bostik |
