Protective coating for wood and concrete forms
Form Seal is a high performance one component moisture cure urethane
that is ideally suited to coat porous wood or concrete formwork. This abrasion and chemically resistant material forms a tough waterproof film that will preserve the life of wood and concrete forms.
All surfaces must be clean and dry before application. Concrete: Prior to application of Form Seal prepare surface with light dust blast or by acid wash. Rinse thoroughly and allow to dry. Wood: Sand rough wood to a smooth surface. If wood grain rises after the first coat, sand lightly before applying second coat.
Apply Form Seal by brush or roller. Two coats are recommended for maximum protection.
First coat: On concrete, thin first coat one to one with solvent (toluene, Xylene). On wood, thinning is not necessary. Allow first coat to cure (typically 2 - 4 hours).
Second coat: For both wood and concrete, apply material directly from container, no thinning is needed. Do not wait more 24 hours to recoat as the first coat will become so hard it will not allow a second coat to stick to it.
300 - 400 sq. ft. per gallon per coat.
