Product Description

Sika Sikafloor ProSeal 90 is a solvent based, clear acrylic resin polymer solution used to cure, harden and seal fresh or hardened concrete floors.

Best Uses

Sikafloor® ProSeal-90 is used for optimum curing and sealing of fresh concrete floors and structures. ProSeal 90 is ideal as a curing compound in order to limit surface drying and cracking and provides curing and sealing for Sikafloor® dry shake hardeners.

Sikafloor® ProSeal-90 is suitable for exterior and interior application as an anti-dust treatment and improvement of the abrasion resistance of existing concrete surfaces.

  • Excellent moisture retention
  • Curing efficiency 90% (ASTM C-156)
  • Good adhesion to old and new concrete
  • Quick drying
  • 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


Fresh concrete:
Surface must be free of bleed water and of sufficient strength to withstand finishing operations. 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 jetting or abrasive blast cleaning. All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum. If in doubt apply a test area first.

Sikafloor® ProSeal-90 is supplied ready for use. Stir thoroughly before use for a minimum of 2 minutes using a low speed electric stirrer (~300 rpm).

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.
