PIERI® FORM SEAL 245 Data Sheet

Polyurethane Form Sealer

Product Description

PIERI® FORM SEAL 245 is a glossy, hard, attractive polyurethane coating that provides outstanding resistance to abrasion, wear and spillage of acids, solvents, salts, alkalis, and water. PIERI® FORM SEAL 245 has a high degree of flexibility and is smooth, slick and hard, which reduces soiling and dirt pickup. Coverage: approximately 150-200 ft2/gal (3.7-4.9 m2/L)


PIERI® FORM SEAL 245 is used to seal wood or concrete formwork and reduce inconsistent absorption. PIERI® FORM SEAL 245 provides temperature resistance to 200°F (93°C).

Directions for Use

Remove any oil and/or grease from the surface prior to use. Spray, roll or brush a thin coat of PIERI® FORM SEAL 245 on the surface. If the surface is very porous, apply a dilute solution of 2 parts PIERI® FORM SEAL 245 and 1 part xylene or toluene to assure better penetration. Apply a second or third coat (undiluted) to the surface while the previous coat is slightly tacky (~25-30 minutes) to improve adhesion. If the previous coat is allowed to dry, sand the surface lightly to roughen it before adding any additional coats. Allow to cure completely for at least 24 hours.
