Installation situation shower tray

Check the surface with test strips (1). ⁄Remove the cover foil (2). Press the test strip onto the wall surface (3) and pull it downwards off the wall (4) so that the foam breaks off and adheres to the wall surface. If the foam can be removed from the wall surface, the surface of the wall must be further treated.

If the bonding test is negative, the spray primer can be used. Spray primer lightly at a distance of 5-10 cm with the window or door open. (Follow the manufacturer’s processing instructions!) New! Craftsman-friendly priming (10 min. drying time).

Preparation of the shower tray

1) Clean the tub rim with the cleaning cloth.

2) Position the tub sealing tape with the upper edge of the gray tub adhesive at the marking line (OKFFB minus tile thickness) (a).

3) Draw a marking line from the top edge of the tub minus the tile thickness (see Fig. 6) all around.

4) Gradually peel off the protective film on the front of the gray tub adhesive (1). Stick the tub sealing tape exactly to the marked line on the tub edge (2). Press lightly with the squeegee, correct if necessary (3) . Press firmly with squeegee against the vertical edge of the tray (4)!

5) Pull off a piece of the protective foil at the beginning of the tub sealing tape (1), then stick the end of the tub sealing tape onto the beginning overlapping (s) and press on firmly! Close the protective foils again.

6) Floor-level installation / overlap only on long side! Measure shower tray (s1+s2) x2, apply tray sealing tape and glue all around. If an extension is required, the tub sealing tape can be applied overlapping on the long sides.

6) Cut the tub sealing tape at 1 and the corners 2 and 3 up to OK gray tub adhesive, do not cut through! Pull off the cover foil strip of the tub sealing tape so far that the sealing corners can be placed on top. After placing the sealing corners, press the protective foils back on!

7) Flexible density corner for corner 2:

8) Flexible sealing corner for corner 2 (floor/floor connection). Remove the protective film from the tub adhesive (black) of the sealing corner, position it on the back of the tub sealing tape and press it on. Press on the protective film of the tub seal+ tape again!

9) Flexible density corner for corner 3:

10) Flexible sealing corner for corner 3 (connection wall/floor). Remove the protective film from the tub adhesive (black) of the sealing corner, position it on the back of the tub sealing tape and press it on. Press on the protective foils of the tub sealing tape again!

11) Straighten corners 2 and 3 and glue them to the tub sealing tape. Press on the protective foils of the tub sealing tape again!

12) Flexible density corner for corner 1:

13) Adjust flexible sealing corner at corner 1 (transition wall/wall/floor) by folding a and b to c and glue to the tub sealing tape at the indicated position. Press on the protective film of the tub sealing tape again!

14) Fold over the sealing corner tied to corner 1 and press it against the sealing tape.

15) Corners 4 and 5 must be cut approx. 10 mm upwards from below at the edge of the cover film’s grip tab (a). Then tear open the film upwards(b).

16) Fold the surrounding tub sealing tape together with the corners by 90° and fix it with adhesive tape. Then finish all around the edge of the tub. The tub sealing tape is thus protected from contamination.

17) Remove the “dust protection” and the tub sealing tape can now be bonded to the wall and floor as shown in Figs. 22-25.

18) After positioning the shower tray, corners 4 and 5 must be stretched. Remove the protective foils.

19) Use the squeegee to press the tub sealing tape exactly into the 90° corner.

20) After removing all protective films at corners 4 and 5, press the tub sealing tape and the remaining corners 1 to 3 to the floor and wall with the squeegee (Fig. 23). In doing so, stroke from the bottom to the top.

Processing bathtub

1)Mark the height of the bathtub waterproofing bath
and attach it in the same way as for the shower tray. Cut the corner up to the upper edge of the trough.

2) Flexible density corner for corner 6.

3) Position the flexible sealing corner on the back of the tub sealing strip, fold up the sealing corner (a) and bond it to the tub sealing strip.

4) Remove all protective films, press corner and tub sealing tape firmly.
