Vulk - Finseal Glow WB - Water based concrete sealer

Typical Properties

Cure & Seal System (AS3799 Compliant)

Finseal Glow WB is recommended for use in conjunction with Aardcure WBS cuing membrane. Apply Aardcure WBS at 1L/5m2 at time of placement followed by Finseal Glow WB as the system topcoat, either on the same day or at the end of project after suitable preparation. This system is AS3799 compliant and provides a solution to construction issues with curing and subsequent coating compatibility.

Curing Time

Curing is dependent on the temperature. The sealer is usually touchdry in approximately 30 minutes at 25˚ C

Estimating Data

Coverage is approximately 5m² per litre per coat. Theoretical coverage for a 2 coats application is approx. 50m² per 20 litre drum.

The properties of the substrate such as porosity and profile will influence the coverage rate and number of coats required

Surface Preparation

Areas to be treated must be clean, dry, free from oil, grease and surface curing compounds.

Freshly Laid Concrete

After surface finishing the concrete must be free of bleed water and sufficiently set to be firm and able to be walked on without marking or damaging the surface.

For New Uncured Concrete

Remove all dirt, grease, oil, paint or curing compounds with Finseal Paveclean / TyreClean or suitable general-purpose cleaner or stripper. Thoroughly wash and pressure clean surface.

A light acid etch prior to application is recommended to ensure unreacted laitance is removed prior to applying to new stamped or exposed aggregate concrete.

Pressure clean surface at minimum 2000psi to prepare for sealing. Allow surface to dry prior to application of the sealer.

Existing Unsealed Concrete

Ensure surface is thoroughly prepared and dirt, grease, staining, oils and contaminants are removed with Fincare Paveclean / TyreClean followed by thorough scrubbing or pressure washing at minimum of 2000psi.

A light acid etch prior to application is recommended to ensure unreacted laitance and loose cementitious material is removed prior to sealing and increase penetration of the prime coat.

Pressure clean surface with a minimum 2000psi to prepare for sealing. Allow surface to dry prior to application of the sealer.

Previously Sealed Concrete

• Ensure surface is thoroughly prepared and dirt, grease, staining, oils and contaminants are removed with Fincare Paveclean / TyreClean followed by thorough scrubbing or pressure washing at minimum of 2000psi.
• Assess any existing sealer is sound, free of delamination and surface whitening. Undertake a cross hatch pull off test to a small area to assess adhesion of existing coating for further sealing.
• If the existing sealer is unsuitable it is recommended that this be completely stripped off prior to new sealer being applied.

Sealer Application

Apply Finseal Glow WB with a low pressure spray unit, lambswool roller or broom.

Care must be taken not to apply thick coats as excessive build may cause the film to blush when subjected to ponding.

A minimum of 2 coats must be applied as part of the sealing system.

Application Method

First Coat

• Slowly stir the material until thoroughly mixed to ensure an even look and sealing properties.
• Apply sealer with low pressure spray unit, lambswool roller or brush at sufficient rate to achieve consistent coverage in even coats.
• Pour material into a tray for application by roller or brush. If spraying, ensure to back roll or broom out any puddles or uneven application areas.

Second Coat

• Apply the second coat in the opposite direction to the first without thinning.
• Subsequent coats can be applied when tack free and a recoat window of 24 hours for chemical adhesion without further preparation.
