Sika® Florseal WB

Test panel applications should be made prior to general application on exposed aggregate, concrete block, stone, precast, coloured concrete, etc. to determine acceptability. Since Sika® Florseal WB may not provide bond for cementitious or other adhesives. Sika Canada recommends that a test trial be performed by the adhesive manufacturer or overlayment applicator prior to general application.

Sika® Florseal WB is not recommended for sealing metallic aggregate hardened floors.

Do not use Sika® Florseal WB-18 & -25 on floors treated with wax or on surface where a solvent-based cure and seal agent is still present.

Maintaining the initial glossy appearance on smooth concrete surfaces may require periodic recoating in the heavy traffic areas.

New or existing concrete, best results are obtained with Sika® Florseal WB-18. Wait a minimum of 72 hours after concrete placement to apply sealer. Existing concrete (minimum 28 days old) surfaces can be sealed with either Sika® Florseal WB-18 or Sika® Florseal WB-25. Do not over apply sealer, use coverage rates list above under “Sealing New” or “Sealing Aged Concrete”. Test samples are recommended to confirm an acceptable result.

Defective mortar, open joints and spalling should be repaired. Surface must be structurally sound and free of foreign matter such as grease, oil, dirt, and incompatible sealers and coatings. Degrease and remove rubber tire marks followed by a thorough rinse with clean water. Apply product to dry surface at 7.4 to 9.8 m2/L (300 to 400 ft2/gal US) depending upon the porosity. Second coat is necessary for maximum protection. Apply after 4 hours drying time at 7.4 to 14.7 m2/L (300 to 600 ft2/gal US.)

For an excellent sealer and added protection to concrete cured with Sika® Florseal WB-18 & -25, apply a second coat after 28 days of curing. If not previously applied when curing concrete, apply two coats, second coat four hours after the first coat. Area to be sealed must be cleaned and free of all foreign matter such as dirt, rubber marks, paint, etc. Apply product at 7.4 to 9.8 m2/L (300 to 400 ft2/US gal) to dry surface.

Application should be made immediately following the final finishing operations as soon as the “sheen” of bleeding water on the surface has disappeared and slab can support the weight of an applicator.

Apply by spray, brush, long nap roller, or lamb wool applicator. For best results, Sika Canada recommends a low-pressure garden-type sprayer with neoprene hoses. Apply uniformly to form a continuous film.

Stir well prior to use, ensuring thorough agitation and distribution of any settled material throughout the liquid. Where necessary, use a paint straining mesh or fabric to collect any material which has formed a surface skin; the presence of which is a consequence of a reaction during packaging and is not representative of any reduction in product quality.

For light traffic, the drying time is 4 hours. And for normal traffic, the drying time is 12 hours.

Also, Sika® Florseal WB-18 & -25 are designed as an initial curing and sealing treatment only, not as a long-lasting traffic bearing coating.

Sika® Florseal WB is dry to the touch after 45 min, but to have maximum hardness, the drying time is 7 days.
