LAYING TECHNOLOGY
1 - Smearing of a coat of primer in the area of the drain pipe (50x50 cm.).
2 - Flame sticking of a membrane layer, which shall be cut by the drain hole.
3 - Heat the membrane surface and place the mouth, making it adhere, in this way, to the lower part of the flange.
4 - Pour by flame from a strip of membrane, smear the descending paste with a trowel on the whole flange, filling, in this way, the cavity of knurls.
5 - Lay the waterproof mantle (II membrane) heating the two surfaces (the impregnated flange and the membrane of the waterproof mantle) well by flame.
6 - Cut the membrane by the hole whose diameter shall be at least 20 mm. smaller than the diameter of the mouth shaft, heat moderately and bend the border towards the inside of the same shaft.
7 - Insert the leafguard.

N.B.: If the waterproof mantle has a single layer, at point 2 replace the membrane layer with piece of membrane, whose dimensions are 500x500 mm. It is advisable to press all the layers laid one on top of the other, energetically.
