Hydrophobic impregnation material for building facades

Sikagard®-703 W is a ready-made emulsion based on a combination of silane / siloxane, waterproof and hydrophobic.

Use

For waterproofing facades and protecting buildings against water ingress. Sikagard®-703 W can be applied to concrete, mortar, masonry, brick, stone, asbestos etc.

Advantages
  • High water impermeability coefficient.
  • Allows the backing layer to breathe (vapor permeable).
  • The treatment is usually invisible, it does not change the appearance of the support layer.
  • Improves dirt pick-up resistance and reduces the growth of fungi, algae and lichens.
  • It can be covered with suitable paints and coatings.
  • Ready prepared.
  • Eco-friendly, water-based.
pack

2 and 5 l drums, 20 l buckets.

Color

Whitish liquid.

Support temperature

+5 °C (+41 °F) min. / +35 °C (+95 °F) max.

Waiting Time / Recoating

Can be covered with water/solvent based polymer paints – contact paint manufacturer for details. When coating with Sikagard® or SikaColor® Emulsion products or other solvent-based coatings, wait at least 5 hours after applying the hydrophobic material.

Strengthening treatment

Sikagard®-703 W does not require special treatment, but must be protected from rain for at least 3 hours at +20°C (+68 °F).

Consumption

Depending on the porosity of the substrate: On concrete and mortar: ~ 150–200 g/m 2 On other porous materials: ~ 300–500 g/m 2 (A test must be carried out to determine the exact consumption).

APPLICATION

Sikagard®-703 W is applied by low-pressure spraying, with a brush or stencil, in a single movement from the top to the bottom, taking care not to run the product.

CLEANING OF TOOLS

Clean all utensils and equipment with clean water immediately after use.

The already hardened material can only be removed mechanically.
