DATA SHEET 7110-501
501 SEALMASTIC solvent-type dampproofing is an asbestos-free asphalt compound containing an exclusive wetting agent to convert a naturally hydrophobic surface to a hydrophilic surface to assure proper coating adhesion. 501 SEALMASTIC is flexible and will span small holes and hairline cracks. The product will withstand temperature changes and will not crack under normal expansion and contraction.
501 SEALMASTIC solvent-type dampproofing is ideal for reducing dampness and moisture infiltration through foundation walls, parapets, fire walls, tanks, culverts, cisterns, and bridge abutments. The product is also applicable for stone-backing, above-grade cavity wall applications, and below-grade masonry wall dampproofing. 501 SEALMASTIC also helps to minimize internal structural damage from mildew and mould. With the addition of a reinforcing fabric, it can also be used as a waterproofing coating.
- Ready to use … no heating or thinning required.
- Dries rapidly … fast and economical way to protect concrete and masonry foundation walls from moisture penetration.
- Easy to apply … no special equipment needed.

Surface Preparation … All surfaces to be coated must be thoroughly cleaned of all scale, loose mortar, dust, rust, dirt, oil, grease, and other foreign matter. Use a wire brush, sandblast, or other methods in keeping with good construction practices. Before product application, fill voids, cracks, and holes in concrete with cement mortar and allow to dry. At temperatures below -20˚ C, use a prime-coat of 600 ASPHALT PRIMER from W. R. MEADOWS, applied at a minimum rate of 4.1 m2/L (200 ft.2/U.S. gal.). Apply at least one coat of 501 SEALMASTIC at a minimum rate of 0.39 – 0.74 m2/L (16 – 30 ft.2/gal.). Do not apply in rain or when rain is threatening.
Application Method … Apply 501 SEALMASTIC with suitable spray equipment. Contact W. R. MEADOWS technical services for more information on spray equipment.
Backfilling … Backfilling should be done within 24 to 48 hours after application. Protect cured application from damage by using PROTECTION COURSE (VIBRAFLEX® PC) and MEL-DRAIN™ from W. R. MEADOWS. Prolonged exposure to ultraviolet sunrays should be minimized.
Cleanup … While still wet, material may be removed with mineral spirits. Once dried, the material can be removed with kerosene or petroleum naptha. Solvent manufacturer precautions should be adhered to when using a solvent for cleanup.
