Vulk - Finseal Glow HD - Heavy duty solvent based sealer

Typical Properties

Curing Time

Curing is dependent on the temperature. The sealer is usually touchdry in approximately 30 minutes at 25˚C.
Protect the sealed surface from rain, water and sprinkler systems for a minimum of 6 hours. Accessible to foot traffic after 24 hours and vehicle traffic after a minimum of 5 days.

Estimating Data

Coverage is approximately 4–5m² per litre per coat. Theoretical coverage for a 2 coats application is approx. 40–50m² per 20 litre drum.

Surface Preparation

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

New Concrete

Freshly laid concrete should be left to cure for a minimum of 14 days prior to application, unless treated with Finseal Glow 24, a same day sealer after finishing.

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.

On ‘tight’ trowel finished concrete surfaces a heavier acid etch preparation may be required to increase penetration and adhesion of the material.
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.

If sound, the existing sealer should be reactivated via application of Finseal Glow 100 solvent and agitated with a solvent resistant broom. Allow to dry before commencing sealing.

Sealer Application

• Apply Finseal Glow HD with a solvent resistant spray unit, lambswool roller or broom.
• A minimum of 2 coats must be applied as part of the sealing system.
• Slowly stir the material until thoroughly mixed to ensure an even look and sealing properties.

Priming

To Resurfaced Concrete

• Apply Finseal Glow HD diluted 20% with Finseal Glow X Xylene to the resurfaced concrete and leave for minimum of 2 hours before applying second coat.

To previously sealed concrete

• Apply Finseal Glow HD diluted 20% with Finseal Glow X Xylene to the resurfaced concrete and leave for minimum of 2 hours before applying second coat.

To new cured or existing unsealed concrete

• Apply Finseal Glow P – Primer / Sealer and allow to dry for minimum leave for minimum of 2 hours before applying top coat.

Application Method

First Coat

• Apply sealer with solvent resistant 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.
• Allow minimum of 2 hours between subsequent coats and a recoat window of 24 hours for chemical adhesion without further preparation.
