SUPER BLOCK™ is a white, fast drying, acrylic waterproofing, highly alkali resistant, bonding primer sealer and stain blocker. It is a waterborne, acrylic multi-use bonding primer. This high performance latex stain killer effectively seals most stains including: water, lipstick, tobacco, nicotine, inks, crayons and knots or sap streaks. Product has excellent resistance to and sealing of tannin stains. It resists checking and cracking when used over bare exterior plywood, T-1-11, Douglas fir or yellow pine. The bond that is formed between SUPER BLOCK™ and the finish coat eliminates any possibility of moisture under the finish coat thus extending the coating’s life considerably. It is designed as a primer coat and stain blocker for most any latex based paint or coating.

SURFACE PREPARATION:
All surfaces must be sound, dry, clean and free of oil, grease, dirt, mildew, form release agents, curing compounds, loose and flaking paint and other foreign substances. All exterior surfaces must be prepared by thoroughly pressure washing with a water and chlorine mixture using at least 1500 P.S.I. to remove any previous coatings, dirt, grease and other foreign materials, especially mold, mildew and algae.
NEW SURFACES: Prepare new surfaces as follows: Concrete, Masonry and Plaster - Cure at least fifteen days before painting, poured in place concrete must cure for at least seven days and the pH must be 9.0 or lower. Roughen slick poured or precast concrete and remove sealers by chemical cleaning or abrasive method such as sanding. Rinse thoroughly with water and allow to dry. Drywall - Remove sanding dust. Wood Interior - Sand smooth and dust clean. Exterior - Counter sink nails. Caulk with latex-type caulk. Slight discoloration on staining woods is normal. If discoloration is considerable, apply a second coat for improved protection. Steel & Metal - Prime & prepare any rust or bare metal with METAL-PRIME RED-OX™ metal primer.
PREVIOUSLY PAINTED SURFACES: Wash to remove contaminants. Rinse thoroughly with water and allow to dry. Sanding not required if the surface is properly and thoroughly cleaned (scuff sanding is required only on glossy, hard, slick or dense surfaces which are subject to high levels of moisture). Remove loose paint. Scrub heavy chalk areas and overhead areas such as eaves with soap and water. Rinse surfaces clean with water and allow to dry for 24 hours. Prime bare areas with primer specified under NEW SURFACES.
APPLICATION PROCEDURE:
Mix thoroughly before use. May be applied by brush, roller or spray. No thinning required. Effectively seals most water stains, inks, crayon, ballpoint pen marks, lipstick, bleeding paints, knots, sap streaks, tobacco, nicotine stains. Some stains may require a second coat. Some highly sensitive stains may require the application of a solvent-based stain sealer for best results. For exterior applications, stop painting at least two hours before you expect heavy dew, rain or temperatures below 45℉ (7℃). For maximum stain resistance, allow four hours before top coating. Low temperature, high humidity, thick films or poor ventilation will increase these times.
Airless Sprayers: Use at least a 1 gallon per minute piston type airless sprayer with a minimum tip size of .017. Remove all line filters and gun filters before spraying.
CLEAN UP:
Clean up all spills, tools and overspray immediately while the coating is still wet with warm soapy water.
NOTE:
SUPER BLOCK™ will not hide stains completely by itself. Once a paint or coating is applied, the stain or blemish should be noticeably sealed. If stains persist, the application of a solvent-based stain sealer may be necessary.
