Level worn-down or damaged treads with repair spatula.
Cut the covering for the riser to size and lay it on. We recommend gluing of the riser. Then put on the base section together with the upper section (The channel in the base section takes up the guide web of the upper section.)
Press the vertical leg of the upper section against the riser in order to find the exact position of the base section on the tread. The leg of the section must firmly lie against the riser.Drill Ø 5 mm holes through the screw holes of the base section. Put dowels through the holes of the base section into the drill holes. Screw down the section. In case of wooden stairs the screw can be screwed directly (without dowel).
Remove the upper section. Glue a 2 mm insulating underlay onto the step for compensating the material thickness of the base section and for sound proofing. Cut the covering for the tread to size and also glue it with the step.
Put on the upper section once again. Select the drilling screws. Three screws of different lengths have been included. The correct screw length can be easily determined by putting the screw into the drill hole. The length is correct if it protrudes by 4–8 mm. Use an accumulator screw driver with PH-1 bit for fixing the upper section. Adjust an average torque. Under low pressure the drilling screws drive a thread into the screw base of the base section.
Slightly beat on the upper section with measured hammer blows until the upper section is in its position.Attention: You must place a wooden support underneath in order to avoid any damage. Then retighten the drilling screws.Dismounting:The screws can be removed at any time without any problem and be screwed into the thread again. For removing the upper section, slightly beat the vertical leg of the section by means of a wooden support.
