Silicone Sealant Performance — at Urethane-Competitive Prices

Need an economical solution for your small- to mid-size projects, without compromising performance? You can’t get better protection for the price than with DOWSIL™ Contractors Concrete Sealant (CCS) and DOWSIL™ Contractors Weatherproofing Sealant (CWS). Unlike organic urethane products, these durable silicone sealants:

  • Are virtually unaffected by UV light, ozone, rain, snow or temperature extremes
  • Stay flexible and maintain adhesion, even while being stretched or compressed over time
  • Will not crack, split or tear

Plus, unlike many urethane or acrylic products with no published warranty, CWS and CCS carry the 5-Year Weatherseal Limited Warranty from Dow Consumer Solutions, a trusted business that stands behind its claims.
