HydroBlock WB
Product Description:

HydroBlock WB™ not only protects, but actively rebuilds original colour and look. 
HydroBlock WB™ is based on the latest nano-technology. A chemical composition of siloxanes with free reactive groups enables HydroBlock WB™ to actively bond to mineral surfaces such as concrete and protect against rain, dirt, algae, pollution, oil and others.

Use:

On dry surfaces of cement, concrete and tile. We recommend a moisturecontent below 45% measured with a Pinless Moisture Meter, Elma DT-128M.

HydroBlock is sold in a colourless version for clay roof tiles, brick facades and mineral surfaces.

Apply directly on surfaces less than one year old. Older surfaces must be cleaned thoroughly with a low-pressure washer of minimum 70bar before treatment.

Surfaces with strong discolouration, algae or moss growth (as well as heavily soiled surfaces) should be treated with A-Clean and finally rinsed with water before treatment. When the surface is visibly dry (after about 24 hours depending on weather, wind and temperature), HydroBlock can be applied.

Apply with brush, roller, garden sprayer or similar. Apply about 1 litre of HydroBlock on 3-5 m2. depending on surface age, property and absorbency. One treatment is sufficient for most surfaces. Additional treatments should be carried out within one hour of first treatment.

Recommendation: Always make a test coat to ensure the compatability of product and surface.
