Ūdens Bāzes Gruntis Caparol Capagrund Universal

White pigmented, highly water vapour permeable special primer for covering priming coats before applying emulsion-, silicone resin- and silicate-emulsion paints on mineral substrates and on existing synthetic (organic) renders/plasters and external thermal insulation composite systems (ETICS/EWI systems). Also suitable as a priming coat for solvent-borne polymer resin paints.

Due to SolSilan technology CapaGrund Universal / CapaGrund Universal-W are highly water-repellent and minimise the risk of calcareous efflorescence when applying tinted finishing coats on alkaline finishing renders/plasters (mortar groups PIc, PII, PIII) and concrete.
CapaGrund Universal / CapaGrund Universal-W are suitable for applying grip and adhesion promoting priming coats and facilitate the following application and texturing of renders/plasters.

CapaGrund Universal-W is provided with a preservative against deterioration in the coating film due to fungal and algal attack.
