Concretal-W
BENEFITS
Protects against steel corrosion and frost damage through high water repellency
Protects against chloride contamination by blocking water transport
Highly vapour permeable (sd ≤ 0.01 m), so concrete re-dries quickly
Consolidates the concrete surface through silicification
Absolutely lightfast mineral pigments (colour fastness A1)
Antistatic, non-thermoplastic binder resists soiling
Mineral matt finish that keeps the character of concrete
Non-flammable: Class A2-s1,d0 to EN 13501-1
Can be renovated without stripping
Very low VOC: 0–2 g/L

KEIM Concretal-W is a one-component sol-silicate protective paint for concrete, classified to DIN EN 1504-2 and highly water-repellent.
It is used to protect exterior concrete facades, and interior concrete surfaces under higher loads such as multi-storey car parks, against water, weathering and chloride. The silicate binder reacts chemically with the concrete, consolidating the surface, while staying open to vapour so the concrete re-dries quickly.
PROTECTION THAT STAYS MINERAL
Concretal-W leaves an even, opaque, mineral matt finish in white or colour, made exclusively with pure mineral, lightfast pigments. With no plastic film to blister or peel, it can be renovated later without stripping.
For extra water protection, pre-treat with KEIM Silan-100.
