Built for the construction period between framing and sale, Fortify is a clear, concentrated mold and moisture resistant, breathable sealer for the protection of the framed structure including sub flooring, joist systems, wall cavities and sheathing. It provides a 12 month warranty to the builder.


From the time that construction materials hit the lumber yard to the time that a building is dried in, the natural environment drives moisture content up. Increased moisture content on primarily wood or wood-based materials supports mold growth. The result can be increased costs to clean the materials during the construction process resulting in less net profit and potential delays. If discovered after project completion, even higher demolition, remediation and reconstruction costs are probable. Fortify, suitable for pre-construction or spray-in-place applications. It protects construction materials prior to dry-in with a breathable but mold and moisture resistant barrier.
