Effective water-based sealers

Our water-based sealers are designed to provide top-quality protection for a wide range of materials. We use innovative water-based formulas that allow effective penetration and the formation of a water-repellent protective barrier on surfaces. Our water-based sealers are solvent-free, which benefits both users and the environment.

We have developed water-based sealers for a variety of surfaces used in finishing work. We offer sealers for:

  • concrete walls, concrete patio slabs, split face concrete masonry,
  • block paving,
  • flamed granite,
  • sandstone (including sandstone walls),
  • ceramic roof tiles

Whatever the material, our sealers not only protect it but also bring out its natural beauty.

Water-based sealers for concrete and block paving

Our water-based sealers effectively increase the resistance of concrete to a range of external factors. They protect against dirt, prevent the development of biological contamination and keep the surface clean for longer. They are alkali-resistant and UV-resistant, so materials stay durable even in harsh weather conditions. We also recommend our water-based sealer for block paving, which gives the desired “wet look” effect, protects against moisture and reduces the formation of efflorescence.

Other CTS Chemistry products

We specialise in professional construction chemicals. In addition to water-based sealers, our range also includes solvent-based sealers for low-absorbency substrates, effective cleaners and unique anti-slip products, which provide greater safety on stairs and floors.
