Wood fire protection

HR Prof


The product is easy to use and does not require a protective finishing coat. It is not harmful to humans, animals or the environment.

 HR Prof can be applied with brush, roller, low pressure spray or vacuum, usually 3 coats that should be applied at intervals of minimum 1 hour.

Consumption: 270 ml/m2 on most wood species, on W R Cedar 360 ml/m2, to ensure a depth of impregnation of 2.0 - 4.5mm into the wood.The substrate to be treated must be dry, clean, without bark, paints or varnishes and free from contaminants. In some instances there may be colour change after application.

Do not apply to wet or frozen wood and do not mix HR Prof with other products.

It is possible to paint or over-coat with some decorative materials once the substrate has dried sufficiently. If over-coating try a small area first to ensurecompatibility.

Drying times are dependent on absorption of the substrate and drying conditions (temperatures and humidity). The approximate drying time is 24-72 hours at + 20 C / 65 relative humidity.

Does not leach once dry.
