Anodized aluminum omega profiles with wall thickness of at least 2.5 mm are mounted to previously prepared concrete floor with 5% slope, at 35 cm intervals with steel dowels. The distance between the two dowels should not exceed 60 cm. According to the dimensions in the project, the places of composite cement slabs cut in the construction site that will come to aluminum profiles are marked. The marked parts of the aluminum profiles and panels are wiped with cellulosic thinner, after drying, primer is applied by brush or roller on these parts of profiles and panels. After 30 minutes, the foil on one side of the double-sided adhesive tape is removed and adhered to the inner edges of the aluminium omega profile. Then the MS polymer adhesive is drawn, along the profile, to the outer edges of the omega profile with a silicone gun. Without allowing MS polymer to dry, the foil on the double-sided adhesive tape is removed and then panel is adhered to the sub-construction. Joints between the panels should not exceed 3mm. The aluminium profiles must be fixed to the floor along the direction of the water flow, on the other hand, the panels should be glued in the opposite direction. After the application, two layers of matt varnish should be applied to the surface of the panels. Cutting should be done with a diamond-tipped frequent saw and no burrs on the edges. If possible, the cutting points should be beveled with a 1mm wide milling cutter.
