ADVICE: Before ordering, do a preliminary test to know the porosity of the support: in dry weather, at a temperature below 20°C and in the shade, pour a few drops of water in several places. Check the absorption time (< to 2 min.: porous / 2 to 10 min.: moderately porous / > to 10 min.: slightly porous). Your substrate should absorb all, or most, of the water within minutes. Otherwise, do not apply our waterproofing agent. Always start with a small amount and then increase if necessary. In case of overdose, the product will have difficulty drying and will become sticky. Consumption: 20 to 100 ml/m² (see details below in "Additional information").
