Lin-Seal White




NO. 354-PD



Technical Description
SEALTIGHT LIN-SEAL WHITE Curing and Anti-Spalling Compound is a true water-base, white pigmented, high solids solution of boiled linseed oil. When properly applied, it provides an impermeable seal which optimizes water retention. The white pigments reflect the heat producing rays of the sun to keep the concrete surface cooler and prevent excessive heat build-up.

SEALTIGHT LIN-SEAL WHITE meets maximum VOC content limits of 350 g/L for Concrete Curing Compounds as required by the U.S. EPA Architectural Coatings Rule.

SEALTIGHT LIN-SEAL WHITE Curing and Anti-Spalling Compound is ideal for use in preventing the spalling and scaling of concrete surfaces. Use on bridge decks, parking garage decks, ramps and/or any concrete surface exposed to water, salts or other deleterious materials. Increases the durability of concrete to prolong its life.
