- Not intended for below-grade waterproofing. Should not be applied if the surface temperature is below 32° F or above 100° F, if rain is expected within two hours following application, or if high winds or other conditions prevent proper application. If rain has preceded the application, the surface should be allowed to dry at least 24 hours. Caution should be taken with specialty coated glass or plastic windows. Check compatibility before application.

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 SW-244-100 VOC except when using asphaltic sealants and other products which are susceptible to solvent attack. While CPI Water Repellents are compatible with most sealants, specific products should be investigated prior to use.
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. Check with your Chemical Products Industries, Inc. representative to verify suitable cleaning methods, products and that the surface preparation is adequate.
Before applying, it is recommended that preliminary tests be carried out to determine usage and to test the effectiveness of the treatment. A coverage rate of 200-250 square feet per gallon is recommended for dense concrete structures including high rises, parking garages and bridge decks.
SW-244-100 VOC should be applied by low-pressure (15 to 25 psi) pumping equipment with a wet fan type spray nozzle. Alternate methods include nap roller (1”) or by brush.
On vertical surfaces, apply in a flooding application from the bottom up so the material runs down 6 to 8 inches below the spray pattern. On horizontal surfaces the liquid material should pond on the surface at least 5 seconds before being absorbed. Coverage rates on horizontal concrete surfaces range from 125 to 400 sq. ft. per gallon. For best results two applications are recommended with the second application applied using a wet on wet technique, i.e., the surface is wet from the first application but not glossy. During application, precautions should be taken to protect the surrounding area from overspray and run off.
