Installation.
It’s simple.

Remove or level out unevenness with a spatula.

Prime the wall and floor surfaces to ensure good adhesion.

Thoroughly clean the substrate.

Cut off protruding remnants of the screed edge strip with a utility knife.

Important: Place the included fleece on the substrate under the waterproof tray to protect the foil from damage.

Use a spirit level to mark the height around the perimeter where the waterproof tray will be placed.

Measure the position of the drain and mark it on the foil of the waterproof tray.

Use a circle cutter to cut the opening for the drain in the foil (make the cut on a clean, flat surface to avoid tearing). Alternatively, scissors or a punching tool can be used.

First, slide the waterproof tray over the drain and position it. Then, peel off the narrow release paper and place the butyl strip along the marked line.

Then remove the wide release paper and fully adhere the fleece lining.

Apply the fleece lining to the substrate as smoothly and without tension as possible, and press firmly by hand or with a roller.

The fleece lining should be integrated into the adjacent surface waterproofing with a minimum overlap of 5 cm. Done.
