Reprotec Blockseal is an aqueous polymer, specially designed to impregnate porous surfaces and imparts a transparent barrier against oil and water, thereby providing stain resistance and release characteristics. It does not alter the appearance of the substrate or its vapour permeability.It also functions as a water, oil and stain repellent on non-porous surfaces.
- Appearance: Pale amber translucent liquid.
- Coverage: 2 - 6m²/Ltr
- Drying Times:
- Touch dry after 1 hour @ 20°C
- Hard dry after 2 hours @ 20°C
Wash the surface to remove contaminants and allow to dry.
Apply Reprotec Blockseal by brush, roller or low pressure spray at a nominal rate of 5m²/litre and allow to dry. A second coat may be necessary for particularly absorbent surfaces. This may be applied after the first coat has dried for a minimum of 2 hours. Allow to dry for 24 hours before service.
Note: for larger areas it is recommended that a small trial area is carried out to establish the coverage rate for the substrate in question.
