Invisible penetrating stain blocking masonry sealer for DENSE SURFACES

Application Guide

IMPORTANT NOTE: Before use on a job, thoroughly test this product in an inconspicuous area to assure performance and appearance. Use only in well ventilated areas.

All surfaces to be treated must be clean and free from dirt, moss, mildew, laitance, efflorescence, and any other contaminate that may interfere with the penetration or reaction of Stain Block Elite masonry sealer to the applied surface. Remove all dirt, wax, oil, paint or sealers with appropriate cleaner, chemical stripper or abrasive blasting. If muriatic acid has been used the surface must be flushed with clean water and neutralized with a pH neutralizer. After cleaning, allow surface to dry 24 hours prior to sealer application. Allow new concrete to cure for at least 14 days before application of sealer. Protect greenery from over spray.

Stain Block Elite masonry sealer can be applied with a sponge, brush, roller, or most types of spray equipment. On dense surfaces one coat, applied to saturation, is all that is required to seal the surface which will assure long lasting protection.  For small areas, a pump-up garden sprayer is convenient. For large commercial installations an airless spray system is recommended. Do not apply Stain Block Elite masonry sealer during wet weather or when surface temperature exceeds 90°F. Application to a damp surface or incompletely cured concrete may cause a hazy appearance or loss of adhesion. Air and surface temperature should be between 50° and 90°F for 24 hours following application. Additional gloss and protection are available with added applications. After each coat perform “water penetration test” (see below).

Brush ................................... synthetic bristle brush.
Roller ............................ "1/4" nap lambs wool roller.
Airless sprayer tip size ................... 0.013" - 0.015”
