USAGE INSTRUCTIONS

Use a putty trowel to apply the reinforcement patch.

Remove the drain cover.
Above the floor trap, cut a round aperture approximately 4 centimetres smaller than the inner diameter.
Press the tensioning ring into the aperture and cut off the excess portion of the insert.
Follow the instructions from the manufacturer of the floor trap. 

Apply a generous layer of waterproofing mastic such as PENOSIL AquaBrake Fiber 640.
Then, around the floor trap, add the floor trap reinforcement patch on top of a layer of freshly applied mastic.
Make sure the reinforcement patch is pressed tightly to the fresh mastic. 
Make sure there are no air bubbles between the mastic and reinforcement patch.

Apply a second layer of mastic on top of the reinforcement patch.
Make sure the reinforcement patch is well immersed in the mastic.

Tips

• Surfaces to be sealed must be clean and free from any dust, loose particles and oil residues. 
• If two patches are applied side by side, leave 5 to 7 cm overlap. 
• Make sure that the cured mastic layer does not contain any holes. It must be applied in an even layer. Verify the quality of your mastic layer before tiling.
