Product Description

Sikafloor Proseal W is a one part water dispersed acrylic emulsion designed to cure, harden, and seal fresh or hardened power floated floors it will also improving abrasion and impact resistance.

Sikafloor Proseal W is a one part water dispersed acrylic emulsion designed to cure, harden, and seal fresh or hardened concrete. Sikafloor Proseal W provides the ultimate way to seal power floated floors and structures made out of concrete and is made up of a curing compound which works to limit the surface from drying and cracking.

Best Uses

Sikafloor Proseal W is best used in commercial and industrial environments for providing an anti-dust treatment all the while improving abrasion and impact resistance to concrete floors. Sikafloor Proseal W is highly suited to indoor use where solvent based products cannot be used due to health and safety regulations.

  • Excellent moisture retention; meets requirements of ASTM C-309
  • Water dispersion
  • Suitable for indoor use where solvent-based products cannot be applied because of health and safety regulations
  • Helps control dusting for both new and existing concrete floor surfaces
  • Effectively cures and seals concrete surfaces in a single, economic operation
  • Non yellowing
  • Easy application by spray or roller
  • Sikafloor®-ProSeal W is used for optimum curing and sealing of fresh concrete floors and structures
  • Curing compound in order to limit surface drying and cracking
  • Provides curing and sealing for Sikafloor® dry shake hardeners
  • Anti-dust treatment and improvement of the abrasion resistance of existing concrete surfaces
  • Suitable for exterior and interior application


Fresh concrete: The concrete must be prepared by suitable power or manual floating / tamping techniques.
Hardened / old concrete: The substrate must be prepared by suitable mechanical preparation techniques such as high-pressure water or abrasive blast cleaning equipment. All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum.

For fresh concrete, apply immediately after finishing techniques have been completed. Apply in a continuous even film by low-pressure spray unit. The suitability of spraying equipment must be confirmed by trials. Application also possible by brush or roller. To achieve the highest visual aesthetics and performance, a second coat is recommended. Wait for first coat to dry tack free before applying a second coat.

Surface and Environment

Sikafloor Proseal W can be used for both interior and exterior applications on both new and existing concrete floors that works to provide a highly protective coating.
