Product descripton

Spray cork is a waterbased decorative and thermally insulating wall coating based on natural cork.   Spray cork has been specially developed for facade applications , for bricks , cementation , ETIC systems , …but can also be used indoors on plaster.

Characteristics

• Suitable for indoor and outdoor use
• Ready-to-use , easy and quick to apply
• Breathable and waterrepellent
• Thermally insulating (reflective conductivity not R-Value, always reflecting heat and cold)
• Elastic
• Excellent fire reaction (Class A)
• Matte aesthetic effect
• Antifungal

Scope of application

Brick , cementation , mineral plasters , base coat of Etic system, …

Surface preparation

The surfaces tob e treted must be clean , free of dust , rust , grease and oil. The surface may be damp to wet (?).

Remove powder formation and flaking thoroughly with a hard ( steel ) brush or with a high-pressure cleaner and thus also remove green deposits and other dirt.

In case of moss growth , treat afterwards with adequate means to remove the spores , allow to dry sufficiently before continuing the work.

Repair mortar joints

Cracks

Dry leaks by applying special rapid cement with a trowel  and allowing to harden.

Always perform an adhesion test on non-current surfaces.

New or unpainted surface.

Old already painted surface.

Chalking surfaces

On a smooth , non-porous surface
