Apply a generous layer of waterproofing mastic such as PENOSIL AquaBrake Fiber 640.

Use a putty trowel to apply the reinforcement patch in the corners.

Then, on the outer corners, add the outer corner 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 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.
