Hydrosil BS

HydroSil BS should be applied directly to a clean and dry surface. Apply with a brush, roller, garden sprayer or low pressure spray. One treatment is sufficient for most surfaces however, if required, a second treatment should be undertaken within an hour of the first. This will ensure that the second coat is fully absorbed together with the first. The surface will be dry in approximately 1 hour.

1-litre covers between 4 - 5 m2 depending upon porosity of surface.

Store in a dry, frost free area and out of the reach of children.

How does Hydrosil BS keep a building clean?

Hydrosil BS is formulated to be easily absorbed into mineral surfaces. This will have a number of beneficial effects one of which is that less water will be absorbed into the surface meaning that water (rainwater) run-off will be quicker which will wash more atmospheric dirt from the surface keeping areas clean.
