A premium interior/exterior waterproofing formula that uses the latest water-based silicone technology designed to penetrate surfaces up to 1/2". This waterproofer creates a barrier inside the surface that keeps water out, but lets trapped water vapors escape; reducing corrosion, spalling, efflorescence and freeze-thaw damage. It reduces staining due to mold, mildew, algae growth and ensures greater durability of the surface. The protection is not worn away with normal use. It protects long after the water beading is gone!
- Concrete & Masonry Waterproofer No. 980 - MSDS
Independent Testing: Passes Federal Specification SS-W-110-C 4.3.2 for water repellency on porous masonry materials and conforms to ASTM E-514, a wind-driven rain test.
Where To Use
A premium formula that uses breakthrough water-based silicone technology to protect horizontal and vertical masonry surfaces such as concrete block, split face block, pavers, stucco, porous or dense brick, unglazed clay tile, exposed aggregate concrete, sandstone and slate. Ideal for untreated driveways, garage floors, patios, foundations and walkways.
Not recommended for use on basement walls or floors subject to hydrostatic pressure (active leaks or continuously damp spots).
CAUTION: Sealed surfaces may become slippery when wet. Use caution when walking on surface when moisture is present. Apply in sections so wet material does not have to be walked on during application.
(The following steps are recommended for best results.)
New concrete must cure for a minimum of 30 days.
REMOVE OLD COATING, if present, for proper penetration and adhesion.
CLEAN: Remove dirt, oil and grease stains with BEHR® NO. 990 CONCRETE CLEANER & DEGREASER. For mildew stain removal, use BEHR NO. 62 MULTI-SURFACE CLEANER & MILDEW STAIN REMOVER. Follow all label instructions.
Repair cracks and holes in the concrete with a Portland cement-based crack filler. All surface repairs should be done at least 3 days prior to application.
TEST: Check for an unseen waterproofer on the surface by sprinkling a few drops of water on the surface to be topcoat-treated. If water completely absorbs into the surface within a few minutes, the surface is porous enough to accept the treatment. If water beads or stays on the surface, you may have a previous treatment that needs to be removed. If so, you will need to strip the entire surface with a chemical stripper. For exterior, use BEHR NO. 64 15 MINUTE QUIK-FIX® DECK FINISH REMOVER & WOOD RESURFACER to remove latex- or oil-based finishes. For 100% acrylic water-based products, use a conventional paint stripper. Refer to product label for specific instructions. For interior, use a chemical stripper designed for interior use. After stripping, re-test surface for repellency.
ETCH: For smooth or new concrete, or for surfaces with efflorescence, use BEHR NO. 991 CONCRETE ETCHER & RUST REMOVER. Follow all label instructions. Wear appropriate eye, skin and apparel protection when applying etching solution. Protect plants and other surfaces from splashing. TIP: Use a plastic watering can to evenly spread the etcher. Working in small sections, apply solution into surface with a stiff bristle broom. On sloped surfaces, work from the lowest point to the highest. Allow etching solution to remain on surface for 5 to 10 minutes. Scrub while rinsing thoroughly with clean water and allow surface to dry. For best results and time savings, use a pressure washer to remove dust and residue.
Repeat the water penetration test.
DO NOT THIN. Stir or shake before applying. Milky white color of product makes it easy to see coverage but it dries clear.
Avoid applying sealer in direct sunlight or to preheated surfaces. Use product when air and surface temperatures are between 50-90°F (10-32°C). Surface must be thoroughly dry for penetration of product.
May be applied by brush, roller or a pump sprayer. Apply until saturated by brush, roller or garden sprayer to a dry surface at the spread rate of about 250 sq. ft. per gallon. Specific spread rates for common materials are:
Clay tile or sandstone 100-150
Concrete cinder block 100-150
Split face block 150-200
Broom-finished concrete 150-200
Unsealed brick (Porous) 150-200
Exposed aggregate 250-300
Unsealed brick (Dense) 300-400
Smooth, hard-packed concrete 300-400
After 5 minutes, remove any surface residue or puddles by spreading product to drier areas or by wiping up excess with a clean cloth.
On vertical surfaces, apply from the bottom up and saturate well.
Allow surface to dry 24-48 hours, depending on temperature and humidity. Once dried, rough, vertical surfaces may be coated with an oil- or latex-based paint or primer. Do not paint horizontal or smooth surfaces after applying this product.
BEHR NO. 980 CONCRETE & MASONRY WATERPROOFER does not need to be applied every year like most other waterproofers. The treatment remains deep in the surface, even if the surface does not bead water. Reapply only if water quickly absorbs into the surface.
Clean all equipment immediately with warm, soapy water. Properly dispose of all soiled rags and protect unused product from freezing. To recycle or properly dispose of paint in your community, call 1-800-CLEANUP (U.S.A. only) or visit www.Earth911.org.
