- Product Highlights
- CP-500W is clear, non-yellowing and does not change the color or appearance of typical surfaces to which they are applied. Buildings and structures stay cleaner because conditions which contribute to staining are reduced and dirt rinses away more readily.
- Advantages
Effective on most vertical or horizontal exterior, above-grade masonry surfaces. Natural substrate color and surface textures are unaffected, with little to no gloss created.
Benefits of this product are:
- Excellent resistance to water intrusion
- Deep penetration into the substrate
- Exhibits good beading effects
- 100% water vapor permeable
- Mildew and fungus resistant
- Efflorescence protection
- High resistance to alkali attack
- Freeze thaw protection
- Can be reapplied to treated surfaces
Chemical Products' state-of-the-art protective treatments have developed a reputation by architects and building professionals as the premier solution for water repellents and sealers. Chemical Products' is dedicated to solving the destructive influence water intrusion and other elements have on building materials.

Applications & Uses
- Applications
- Application Area
- Applications
- Recommended surfaces include: architectural precast or cast in place, concrete, brick, mortars, natural stones, limestone, granite, sandstone, terra cotta, ceramic tile and grout, adobe, exposed aggregate products, Portland cement stuccos, plaster and concrete masonry units. Protects horizontal surfaces such as pavements, sidewalks and plazas. It should also be used on vertical surfaces with leaks and or where extra protection is desired. Also protects bridges, parking decks, airport taxiways and aprons, piers and marine structures, and other surfaces requiring outstanding corrosion resistance and protection from chloride penetration. For use on brick masonry to protect against the entrance of wind-driven rain. To reduce the effects of mildew, efflorescence, and stains from concrete and masonry.
- Pretreatment For Paint
- Water can penetrate through most paints and coatings. This leads to damp substrates and blistering and peeling of paint. Pretreating concrete, masonry, or stucco with CP-500W prior to painting keeps walls drier and extends the life of the paint. CP-500W is compatible with most latex and other paints. But to assure compatibility between paint and pretreatment, a small test application is recommended. Note: Do not use a pretreatment or allow overspray on metal or other nonporous surfaces to be painted.
- Limitations
Not intended for below-grade waterproofing. CP-500W will leave a residue on non-porous substrates such as glass windows, metal frames and painted surfaces. Caution should be taken with specialty coated glass or plastic windows. Check compatibility before application. Protect materials which can be damaged by solvents. Do not apply when following conditions are present:
- Ambient or surface temperature less than 40° F or predicted to fall below 40° F within 24 hours following application.
- Rain within 72 hours prior to application or predicted within four hours after application.
- Wet or frozen substrates.
- High winds which could cause excessive overspray.
Application should be completed by qualified applicator with experience applying water repellents. Application equipment should be clean and free of foreign materials which could be dissolved and deposited on surfaces to be treated. Contact CPI for additional precautions and information on compatibility with specific materials.
- Vertical Surfaces
- Mix well before using. Test small area before starting general application to assure desired results and coverage rates. Before application, precautions should be taken to protect the surrounding area from overspray. Apply when surface and air temperatures are between 40°F to 110°F. Provide adequate ventilation. Apply in a flooding application, from the bottom up so the material runs down 6 to 8 inches below the spray pattern i.e. “wet on wet”. A wet treated surface may be agitated with a soft bristle scrub brush to ensure more even distribution and greater penetration. Remove overspray from non-targeted surfaces immediately with soap and water. Apply to southern exposed areas during coolest part of the day.
- Horizontal Surfaces
- Mix well before using. Pretest to measure material coverage rates. Before application, precautions should be taken to protect the surrounding area from overspray. Apply enough material so that solution stands for 60 seconds before completely penetrating the surface. Solution should penetrate the surface and should be fully absorbed. Puddling or ponding may cause darkening or surface discoloration after curing. Brush or broom any excess solution to spread material to untreated areas. If applicable, block all drains and use absorptive coverings to contain run-off of excess material. To avoid unnecessary clean-up, use soap and water to remove overspray as soon as possible.

- Installation
Best results are obtained by applying CP-500W on clean and dry substrates. All surfaces must be cleaned to remove all traces of dirt, dust, efflorescence, mold, salt, grease, oil, asphalt, laitance, curing compounds, paint, coatings and other contaminants. Acceptable surface cleaning methods include shotblasting, sandblasting, waterblasting and chemical cleaners. If chemical cleaning agents are used, neutralize and wash off residues completely. Allow surface to dry at least 72 hours after water cleaning. Check with your Chemical Products Industries, Inc. representative to verify suitable cleaning methods, products and that the surface preparation is adequate. As a standard procedure, fresh concrete should be allowed to dry for 28 days before application. All repointing must be completed and allowed to cure at least 3 days. Concrete repair and replacement must be completed prior to application. Patching materials, caulking, sealing materials, traffic paint must be fully cured before applying CP-500W. In addition, the actual amount of material that is used for each application is dependent on the absorptive capacity of the substrate. Before applying, it is recommended that preliminary tests be carried out to determine usage and to test the effectiveness of the treatment. Precautions should be taken to protect the surrounding area from overspray.
Application: Apply water repellents as early as practical to protect substrates during construction, but not before wall cap, flashings, and roof are in place and water trapped in structure has been drained. Spray apply CP-500W by low-pressure (150 psi maximum) pumping equipment with a wet fan type spray nozzle. Alternate methods include nap roller (1”) or by brush. Required application rate varies from 70 to 175 sq. ft. per gallon depending on surface texture and absorbency.
