WATER HOLDING PROPERTY Water permeability >> When water is poured on the material with a hose, almost all water flows down through pores of the panel and does not penetrate into the back of the panel. Almost no water remains in the panel Water drainage >> Water material dries by 80 % in 2 hrs at 20 centigrade With doublesided tape and screws or rivets (see the mounting instructions). When applied as wall cladding below 2 m, a perforated panel (wood, steal, gypsum) will be placed behind the Poal sheet to insure stability. With a perforation rate of min. 20 % (e.g. diameter 8 mm, grid 16 * 16 mm)...
