Moisture Barriers for facades
Sikagard®-703 W
Sikagard®-703 W is an emulsion, ready for use, silane / siloxane combination based, water repellent impregnation.
Use
For making facades water repellent and protecting building against water ingress. Sikagard®-703 W can be applied on mortar, masonry, brick, stone, asbestos cement.
Characteristics and Advantages
- Strong water repellent capability.
- Allows the substrate to breathe (vapour permeable).
- Treatment is usually invisible not changing the substrate aspect.
- Due to the reduction of water absorption, it improves the resistance of facades to stain and dirt pick and helps the reduction of moss and lichen growth.
- Can be over coated with suitable paints and coatings.
- Ready to use.
- Water based environmental friendly.

Sikagard-703WSikagard®-905 W
Sikagard®-905 W is a ready to use, water based resin damp-proofing and hardening impregnation. Sikagard®-905 W is clear after drying. Sikagard®-905 W forms a physical barrier which prevents mould and biological growth.
Use
Sikagard®-905 W is used to prevent damp in plastered or rendered surfaces, brick or stone. Due to its low viscosity, it penetrates deeply into the substrate and forms an invisible water damp-proof barrier.
- Saltpetre treatment
- Prevention of mould growth by reducing the water absorption.
- Damp-proofing and surface hardening
Sikagard®-905 W is also used as a surface hardener for weak and dusty substrates, both indoors and outdoors.
Sikagard®-905 W can be used as a pre-treatment improving surfaces for painting works on weak or dusty surfaces.
Characteristics and Advantages
- Very low viscosity
- Almost invisible after drying
- Can be over-coated with paint or wall paper
- Can be used internally and externally
- Does not contain any biocide or any algaecide raw material
- UV resistant

Characteristics and Advantages
- Excellent penetration
- Fast uptake even on dense concrete
- Economic and easy to use
- Reduces capillary water absorption, protection against driving rain and splashing on vertical areas
- Reduction of absorption of aggressive or deleterious agents dissolved in water (i.e. de-icing salts or chloride from marine environment)
- No change in water vapour permeability
- Long term efficiency, deep penetration
- Increases the resistance of concrete to freeze and thaw cycles and de-icing salts
- Reduce corrosion even in cracked concrete
- Retard corrosion initiation by reducing the available humidity at reinforcement bars level
- Mitigate corrosion by preventing further chloride to migrate to reinforcement bars
- Comply with Dutch guidelines (RWS NEN-EN 1504-2) on CEM III
- Resistant to sea water
- Low VOC content
- Ready to use
