Moisture Barriers for facades

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.

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

Use

Sikagard®-705 L is used as water-repellent impregnation (hydrophobic treatment) for absorbent substrates such as concrete in civil engineering or building concrete structures subjected to heavy stress due to freeze and thaw cycles and de-icing salts and chloride attack in marine environment

• Suitable for protection against ingress (Principle 1, method 1.1 of EN 1504-9),
• Suitable for moisture control (Principle 2, method 2.1 of EN 1504-9)

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
