Protective coatings on Van den Weghe natural stones

Van den Weghe wants to expand the application of natural stones in wet areas (bathroom, sauna, kitchen,…) and in outdoor applications such as pools or outdoor bars.

However, water penetration, acid etching and staining is limiting the use of porous natural in these areas.

Sirris Smart Coating Application Lab has applied and tested several coatings to increase the acid resistance and stain repellency of porous natural stones.

Tests show promising results:

a) Acid resistance test

Acid test results

b) Stain test
