Guard Hardener® W is a product for mineralising and treating efflorescence, saltpetre, friable materials damaged by intrusion of water, damp, frost...
Guard Hardener® W penetrates friable materials certainly to crystallise, harden and mineralise. Once treated, materials become more resistant to degradations. Guard Hardener® W can also be used as an anti-dusting treatment.
Guard Hardener® W also has excellent water-repellent properties that help to prevent main causes of degradation such as infiltrations, acid rains, erosion, freeze-thaw cycles, development of micro-organisms, saltpetre, efflorescences...
Guard Hardener® W is a non film-forming impregnation product. Substrates remain permeable to air and water vapour. It is completely colourless after application and does not change the appearance or the composition of the treated surface. It is also UV-resistant and does not discolor with age.
Guard Hardener® W can be used indoors and outdoors on facades, walls, roofings, floors, screeds and on all porous materials: cement, plaster, concrete, natural stone, brick, render...
Hardens and consolidates porous friable materials.
“Anti-dusting” action.
Protects against water, humidity and frost and thus limits development of efflorescence, moss and lichens.
10 year efficiency.
Colourless.
Non film-forming, lets a surface breathe.
Water-based product, solvent-free and non flamable.
Apply using a low pressure sprayer, a brush or a roller.
Clean tools and equipment immediately after use with water.
Apply the product to a surface that is clean.
A mechanical cleaning with a brush or chemical cleaning can be done.
To remove stains and marks of pollution use Guard Cleaner® Polluted facades. In case of greasy stains use Guard Cleaner® Eco Soiled floors. For efflorescence or saltpetre use Guard Remover® Eco Efflorescence & cement.
Apply product neat – do not dilute.
Shake the product well before use. Always carry out a preliminary test.
Apply to the point of saturation of the substrate in 1 layer or in 2 layers «wet on wet» according to the porosity.
Do not overcharge the substrate – remove all excess before it dries. Risk of white stains in case of excess.
Full efficiency achieved after drying 2 to 7 days.
The treated substrate must not be covered by another coating.
