ArexA Hydro-Concrete

ArexA HYDRO-Concrete

ArexA-HYDRO-concrete is a permanent, up to 6 cm deep penetrating waterproofing

 

What is hydrophobizing?

Hydrophobizing prevents the capillary system of concrete from water penetration in all open-pored, cement-based and mineral surfaces in- and outdoors.

ArexA-HYDRO concrete builds a strong water- and dirt-repellent surface, which is easy to be cleaned. Deposits of moss, fungi or algae are avoided. It protects the material against efflorescence, air pollution and UV radiation.
Furthermore, it offers a transparent protection on all kind of masonry/ concrete surfaces and preserves the natural appearance. ArexA-HYDRO-concrete is colorless, inodorous, solvent-free, not flammable and nontoxic. It does not leave a coating but a clear and natural surface.
In commercial areas, ArexA-HYDRO-concrete is applied mostly to obtain a natural surface with repellent function against water, any kind of liquid (oil, grease, wine, coffee etc.) simple color and environmental conditions.
Old (untreated) stones and bricks receive their original look again, react impermeable to water and are protected permanently. Furthermore, heating and energy costs are reduced due to drainage of masonry and the protection against penetrating rain.
Typical applications are walls, floors and ceilings, chimneys, roof tiles, terraces, flat roofs and swimming pools made of concrete.

How does ArexA-HYDRO-concrete work?

ArexA-HYDRO-concrete waterproofs all openpored, cement-based and mineral surfaces in- and outdoors, including all kind of concrete, screed, bricks, clinker bricks, argil, and different types of stone (e.g. sandstone, terra-cotta, etc.). ArexA HYDRO-concrete develops a strongly water- and dirt-repellent surface, prevents from moss, fungi and algae, and is easily cleaned. ArexA-HYDRO-concrete prevents the treated surface from efflorescence, air pollution and UV radiation.

Advantages

• Application is easy and unproblematic
• Odorless
• Environmental friendly
• Breathable
• Acid resistant
• One-layer treatment
• Elongated durability
• Reduced service necessity
• Dust binding
• Easy cleaning

Characteristics

  • Colorless, odorless, solvent-free, not flammable and nontoxic
  • Does not leave a separated coating, but a transparent, clear and natural surface
  • Water-soluble potassium methylsilane triolate with an organic catalyst, not film-forming, high capillarity, not flammable
  • Waterproofs mineral building materials up to a depth of 60 mm (in a one- or max. two-layer application, wet-on-wet technique) and develops a water-repellent surface

Material

Pure natural product based on water-soluble potassium methylsilane triolate ready-for-use with an organic catalyst.

Processing

Turn the canister upside down and shake it well. You get the best and evenly results when ArexA-HYDRO-concrete is applied with a standard pressure sprayer. On small areas, it is also possible to use a roller, brush or sponge for application. The surface should be treated thin and evenly in order to prevent from ponding. ArexA-HYDRO-concrete must not be diluted with water and only be transferred into new, unused casks. Usually one treatment is enough. We recommend an additional treatment on strongly absorbing surfaces – wet-on-wet.
Attention: ArexA-HYDRO-concrete is hydrophobic. Therefore, it cannot be applied on surfaces to be treated with additional materials. An further application with paint for instance after the treatment with ArexA-HYDRO-concrete is not possible.

Examaples for applications

  • Brick front (sealing, stone refurbishment, reduction of energy costs, joint sealing) – e.g. refurbishment of listed buildings
  • Unsealed stone floors (calcareous sandstone, sandstone, granite, schist, terra-cotta, basalt etc.)
  • Kitchen work plates, bathroom shelfs, windowsills from unsealed stone
  • Unglazed ceramic tiles (e.g. terra-cotta, granite, schist etc.)
  • External walls and walls and stone masonry
  • Mineral plaster (without any chemical or water-repellent substances)
  • Garage floors with optical characteristic of fair faced concrete (to prevent from oil spots etc.)
  • Roof tiles (unglazed, made of ceramic or concrete) – can be sealed (broken tiles to be exchanged before application)
  • Swimming pools made of fair faced concrete (pre-treatment with ArexA-HYDRO-concrete)
  • Sealing of joint in showers, shower and toilet pods, swimming pools
  • Chimneys (brick or other kind of stone masonry)
  • Flooring screed (e.g. floors of factory halls etc.)
  • Flat roofs (pre-treated with ArexA-HYDRO-concrete)
  • asbestos cement / corrugated sheets (wall covering or roof)
  • wells and garden decorations made of concrete and stone
  • terra-cotta plant pots (keep their natural optic and become frost-proof)
