Approx. 50–100 ml/m2, i.e. 1 liter of PNZ WPC Impregnation is enough for approx. 10–20 m2 depending on the structure of the surface. With fluted surfaces, consumption may be doubled or tripled.
The product may be recoated also when dry after approximately 8-12 hours. With wet and cold weather, the drying time may be longer. Re-coat as needed.
