SOPRALINER - Chapter 3: PVC Liner setting on the stair

Before covering the stair with SOPRALINER it is necessary to tailor-cut the membrane for the first raiser, starting from the bottom of the swimming pool. Perform this operation on a horizontal surface using adequate measurement tools. Mark the cutting line with a chalk line on the lower side of the PVC membrane (the one that is not visible). Use a cutter to cut and set the membrane in the swimming pool after spreading Flagpoolcol on the base and on the membrane. Make the membrane adhere on the base and cut the exceeding material. Weld the vertical walls using the hot air welding device and the brass roller. Repeat the same operation on the second raiser. Cut the slip-prevention membrane SOPRALINER with the desired colour. Set it on the horizontal surface of the first step. Point and cut the exceeding material before welding it on the raisers. At the end of this procedure, the first step is finished. Repeat the above-described operations for the other steps, setting the slip prevention membrane on the entrance step on the top of the swimming pool.
