The film has a high degree of flexibility and works extremely well pre-treating wood and concrete formwork where medium re-use of up to 40 casts are expected. Form Seal can be used to seal all types of wood or concrete formwork. Application : Remove any grease or oils form the surface prior to use. Brush, roll or spray a thin coat of Form-Seal. If the surface to be coated is porous it is best to apply a dilute solution of 2-parts Form Seal and 1-part Xylene to assure better penetration. Apply a second or third coat to the surface while the first coat remains tacky to assure proper adhesion. If the first coat has dried prior to the application of subsequent coats lightly sand the surface to roughen it and create a better anchor profile for proper adhesion. Note: When applying Form- Seal to concrete mix it is best to lightly sandblast or acid etch the surface prior to applying the coating. If acid etching is preferred, it is best to wait a minimum of 48 hours before proceeding with the Form Seal, allowing for thorough drying of the concrete substrate to be coated. Coverage : 1 gallon yields 300-400 sq. ft. per coat. 2 coats recommended. Specifications: Specific Gravity: 0.985 Tensile Strength: 3,500 psi Drying Time: 2-1/2 hours Elongation: 150% Impact Resistance: 160 in-lbs Read manufacturers' data sheets for complete specifications, installation procedures, and MSDS precautions.
