SOPRALINER - Chapter 2: PVC Liner setting on vertical walls

The pvc membrane setting in a free shape swimming pool starts from its vertical walls. Cut lengthwise FLAGPOOL membrane with the colour chosen to line the walls. Hot weld (at approx. 450°C) the pvc fixing strip on the back of the membrane. Set the membrane on the vertical walls introducing the anchoring border into the anchoring profile along the swimming pool’s perimeter fixing it with the fastening borders. Eliminate the exceeding membrane on the bottom of the swimming pool and continue the setting overall the vertical wall. The minimum overlap on the bottom of the swimming pool is 5 centimetres. Cut the overlapped material with several perpendicular cuts to enhance the elimination of the exceeding membrane. When covering a Roman style stair with a cotton or sponge roller, spread a layer of FLAGPOOLCOL on the side walls and on the first riser of the stair and repeat the operation with the membrane used to cover this area. Adhere the membrane on the vertical wall and on the overlap of the bottom (do not use fixing nails to cover the the steps). Prepare the overlap of the steps bending the membrane with a 45° angle, cutting the exceeding material. Fix the remaining overlaps with expansion nails having a centre-to-centre distance of about 10 centimetres. Remove the exceeding membrane. Weld the vertical overlap above the setting starting line, overlapping by 5 centimetres. Qualified setting companies must perform the above-described operations.
