Description

ALLPRO® PRIME & SEAL™ Acrylic Water Sealant is a clear, water-based acrylic sealer formulated for use as a clear finish coat on interior brick and masonry surfaces or to reduce moisture penetration on exterior, above grade, non-porous aggregates, such as brick, stone, smooth masonry, and other moderately dense substrates. The product can also be used as a bonding type primer over chalky surfaces or as an additive to acrylic latex paints to help improve adhesion over most painted or unpainted vertical surfaces, including masonry, concrete, block, wood, and aluminum siding. When dry, Prime & Seal provides a subtle satin finish to the substrate. Easy-to-use water clean-up formula.

Uses

Ideal for use as a water repellent on smooth concrete and masonry, stucco, brick, stone, adobe, drywall, plaster, grout, pottery, galvanized metal, vinyl siding, and more. Prime & Seal can also be used as a masonry conditioner for binding moderately chalk-laden surfaces prior to final coating with top quality exterior latex house paint or elastomeric coating. By sealing the substrate surface, Prime & Seal increases the overall waterproofing performance of topcoats, as well as extending top coat coverage - a cost saving advantage.

 

Limitations Do not use over extremely dense or polished surfaces. Do not use on extremely porous surfaces. It is not suitable for use over asphalt surfaces nor is it recommended for below grade applications. ALLPRO Prime & Seal will not prevent water penetration through structural cracks, defects, or open joints. The application of Prime & Seal will reduce the vapor transmission rate of the substrate which can result in a "blushing" effect to the surface during extremely moist conditions. Do not apply when temperature of surface or air is below 50 degrees F (10 degrees C). If rain or threatening weather is expected within 8 hours, delay application until dry conditions. Never apply to frozen or frost covered substrates. Do not apply product to wet or water saturated substrates or when relative humidity is above 90%. Not for use below grade or under water. Do not use on horizontal surfaces. KEEP FROM FREEZING.

 

Surface Preparation The most important factor in achieving a durable, quality finish is proper surface preparation. The substrate must be free from all surface contamination such as dirt, dust, laitance, mold, mildew, mortar, mill scale, loose paint, surface efflorescence, grease, oil, excessive chalk, and foreign matter. The removal of grease, oil, and dirt is best achieved by pressure cleaning while utilizing commercial degreasers. Neutralize chemical cleaners, and complete tuck-pointing, crack and delamination (spalling) repairs prior to the application of Prime & Seal. Remove previous coatings by mechanical means (Caution: read all warning statements pertaining to dust masks, etc.). Do not apply over coated surfaces without testing for compatibility and adhesion.

Efflorescence is best removed by scraping and wire brushing the surface. Dust, dirt and chalk are best removed by high-pressure water blasting. To determine if the chalk has been sufficiently removed, wipe hand over the dried surface; if a powdery colored residue is still visually evident on the hand, then more high-pressure water blasting is required to remove this chalky layer to a practical bare minimum. Removal of laitance and any other under bound chalk-like matter is best achieved by etching the surface with a dilute solution of Muriatic acid; i.e., 4 parts water to 1 part Muriatic acid. Note: Always be sure to read all manufacturers' instructions pertinent to degreasers and Muriatic acid solutions prior to use.

 

Application Apply when temperature of surface and air is above 50 degrees F (10 degrees C). Prime & Seal is alkali resistant, and can be applied to masonry surfaces 14 days after construction.

Cementitious Surfaces:
Prime & Seal is ready for use. Do not thin. Apply Prime & Seal to a clean, dry surface by roller, HVLP (high volume low pressure spray system), or airless spray system. For maximum effectiveness, two (2) coats should be applied, allowing four hours between applications. Areas not being coated, such as windows and shrubbery, should be protected from overspray. Prime & Seal may be mixed in a 1-1 ratio with acrylic paint to produce a pigmented primer/sealer or used, by itself, as a clear bonding primer/sealer over chalky surfaces. To improve the weatherability of latex paints, add Prime & Seal in a 1-4 ratio (approx. one gallon of Prime & Seal per 4 gal. latex paint.

Wood:
Due to its water repellent properties and built-in U.V. resistance, All Seal protects wood from the premature damaging effects of repetitious water absorption while allowing the wood to age naturally. Prime & Seal can be applied to most above-grade wood building construction*. Follow above directions.

*Do not use on wood that has been recently surface treated with insecticides and/or chemical preservative compounds that prevent dry rot.

 

Clean Up Clean equipment with soap and water.

NOTICE: This product contains solvents. reports have associated repeated and prolonged occupational exposure to solvents with permanent brain damage. Intentional misuse by deliberately concentrating and inhaling the contents may be harmful or fatal. For emergency information within the United States, call (800)424-9300; outside the U.S. call (703)527-3887 [CHEMTREC]. For additional safety and chronic hazard information, refer to Material Safety Data Sheet for this product. See label analysis for list of primary ingredients. Close container after each use. If sanding is done, wear dust mask to avoid breathing of sanding dust. IMPORTANT! Spray equipment must be operated with care and in strict accordance with manufacturer's instructions. Avoid breathing vapor, spray mist or sanding dust. Wear an appropriate, properly fitted respirator (NIOSH/MSHA approved) during and after application unless air monitoring demonstrates vapor/mist labels are below applicable limits. Follow respirator manufacturer's directions for respirator use. FIRST AID: In case of skin contact, wash off quickly with plenty of water, then soap and water; remove contaminated clothing. For eye contact flush immediately with large amounts of water, especially under lids, for at least 15 minutes. Obtain emergency medical treatment. If swallowed, obtain medical treatment immediately. If inhalation causes physical discomfort, remove to fresh air. Restore and support continued breathing. Have trained person give oxygen if necessary. If discomfort persists or any breathing difficulty occurs, get medical help. In case of spillage, absorb with inert material and dispose of in accordance with applicable regulations.
