LIN-SEAL penetrating and anti-spalling compound is a specification-grade formulation of boiled linseed oil in mineral spirits. LIN-SEAL is specifically compounded to prevent the spalling and scaling of concrete. This type of penetrating compound is recommended by many state Departments of Transportation for prolonging the life cycle of concrete exposed to water, de-icing salts and other destructive materials.

Surface Preparation
Surfaces to be sealed must be clean and dry. Remove all dirt, oil, grease, curing compounds and other substances that would prevent the proper penetration of the LIN-SEAL.

Application Method
Apply at temperatures between 40-90° F (4-35° C). New concrete should be cured a minimum of 28 days before application. Apply using an industrial sprayer. A Chapin 1949 sprayer with a 5797 spray tip that produces a flow of ½ gallon (1.89 L) per minute under 40 psi (0.276 MPa) of pressure (or equivalent) is recommended. AVOID PUDDLING in low areas. If puddles occur, brush or roll them out. Annual reapplication may be necessary.
NOTE: Proper application is the responsibility of the user and/or specifier. The user and/or specifier shall determine suitability of a product for a specific application, and assume all related responsibility. Field visits by, or conversations with W. R. MEADOWS personnel or their representatives, are for the purpose of making technical recommendations only and are not to supervise applications or provide quality control on the jobsite.

Coverage
Apply at the rate of approximately 300 ft.²/gal. (7.36 m²/L). A second application at approximately 600 ft.²/gal. (14.73 m²/L) is recommended for increased protection and spall prevention.
NOTE: Use of fillers, extenders or additives in the concrete mix may result in higher porosity. To achieve proper protection, adjust coverage rates to compensate for the resulting penetration.

Clean up
Use mineral spirits or other suitable petroleum solvent to clean tools and equipment. Materials soaked with linseed oil (rags, paper towels, absorbents, etc.) may spontaneously catch fire if improperly disposed. (See precaution below.)
