Description

Sikagard®-545 W Elastofill is an elastic acrylic copolymer dispersion intermediate Sikagard®-545 W Elastofill is part of a crack-bridging system comprising of:

• Sikagard®-551 S Elastic Primer (solvent containing) or
• Sikagard®-552 W Aquaprimer (water-based) as a primer

Uses

Sikagard®-545 W Elastofill is designed as a crackbridging intermediate coat in combination with Sikagard ®-550 W Elastic.
Sikagard®-545 W Elastofill as a filler coat closes pores, cavities and blowholes.
Sikagard®-550 W Elastic as a coloured top coat protects and embellishes.
Sikagard® crack bridging system is used for protection and enhancement of concrete structures (normal and lightweight concrete), especially outdoor exposed concrete surfaces with a high risk of cracking.

• Suitable for protection against ingress (Principle 1, method 1.3 of EN 1504-9)
• Suitable for moisture control (Principle 2, method 2.3 of EN 1504-9)
• Suitable for increasing the resistivity (Principle 8, method 8.3 of EN 1504-9)

Advantages

• Water thinnable, ecologically harmless
• Easy to apply
• Easy filling properties for pores, small cavities and blowholes
• Outstanding carbonation inhibitor
• Good water vapour permeability
• Crack-bridging even at low temperatures (-20°C)
• Can retain board mark texture/formwork patterns if required
• Resistant to freeze/thaw and de-icing salts
