Mathys Pegagraff Hydro

Mathys Pegagraff Hydro

Mathys Pegagraff Hydro is a clear, satin, two-component waterborne polyurethane acrylic lacquer. Mathys Pegagraff Hydro is a clear coating designed to protect a range of bare and previously painted surfaces inside and out from graffiti attack. Mathys Pegagraff Hydro can be applied by brush, roller or spray onto surfaces to floors, walls and other surfaces to create a tough, clear glaze that can be easily and frequently cleaned to remove any unwanted graffiti that may occur.

Suitable and Unsuitable Substrates:

Painted substrates
In principle, direct application on ALL painted substrates is allowed, with exception of elastomeric coatings, i.e. Murfill. A test surface has to be realised beforehand for heat curing paints and for powder coatings.

Not painted or untreated substrates
Only on reinforced concrete (remaining humidity level < 4 %), Pegagraff Hydro can be applied directly.

Not recommended substrates
a) Do not apply Pegagraff Hydro on a mineral painted substrate where the relative humidity is higher than 6%. This concerns bricks, terra-cotta tiles, renderings, etc. In this case, a white film could be formed and more or less important adhesion loss will appear.
b) Do not apply Pegagraff Hydro directly on not painted metal substrates such as aluminium, steel, zinc, stainless steel, copper, etc.
c) Do not apply Pegagraff Hydro directly on bare wood for exterior applications.
d) Do not apply Pegagraff Hydro directly on rough surfaces such as plaster, rough brickwork (masonry), etc.
