SilaCryl-based, deeply penetrating, special primer with hydrophobic effect. For exterior and interior use.
Detectable due to a special black light-reflecting finish.
Primer to equalize/level the absorbency on rough, porous, absorbent or slightly sanding render/plaster and concrete surfaces and interior gypsum building- and plasterboards, before applying emulsion-, silicone resin- or polymer resin paints.
OptiGrund may also be used in rooms without explosion-proof fittings or in insufficiently ventilated areas, as well as in rooms used for processing or storing foods and luxury foodstuffs.
Due to the special SilaCryl technology (extremely fine particles) the primer is deeply penetrating to the substrate and enhances hydrophobic properties. In conjunction with a black light lamp, the special UV indicator provides verification of priming even after a following coat.
To do this, the coating is carefully scraped away down to the substrate and illuminated with an ultraviolet lamp. OptiGrund is then characterised by a bluish/purple reflection.
- Low odour.
- Enhances hydrophobic properties.
- Easy to apply.
Silicone modified, aqueous acrylic resin hydrosol.
