Surface preparation:
The concrete substrate should be seasoned (for a minimum of 28 days), sound, free of dust and flaking paint coatings and free of grease. If the surface has traces of grease, wash the surface with pressurised detergent water, rinse and dry. Otherwise wash with pressurised water or sand the surface.
Moulded, mossy or algae-infested areas should be mechanically cleaned and disinfected with appropriate products, e.g. Fungicide.
Substrate must be dry, with a maximum moisture content of 4 -6 % and a temperature of +5°C to 30°C, before painting. This is when the hydrohobic effect is most effective.
Painting:
Apply at least two coats u0022wet on wetu0022. The number of coats depends on the requirements. For traffic engineering structures, i.e. bridges, noise barriers, use application to saturate the surface. Apply using the bottom up technique and avoid run-off.
To apply the impregnate to large areas it is best to use a low pressure spray. The impregnate can also be applied with a roller or brush.
Apply at a temperature of +50C to +300C and a relative humidity of up to 60%.
Paint work should be carried out in suitable atmospheric conditions (no fog, rain or snow).
Use water to wash paint tools.
