Step 1
Thoroughly roughen the contact surface with coarse sandpaper. Ensure the surface is clean and dry before proceeding. (Clean with water only. Other cleaning methods may leave residues that can affect adhesion.)
Step 2
Remove the backing paper approximately 100mm at a time. Position the butyl approximately 2mm above the top edge of the shower tray or bath. Press firmly into place by hand as you work around the tray or bath, maintaining the 2mm position throughout.
Step 3
Before applying around the corners, pinch the Classi Plus to allow extra material in the corners – this helps with subsequent tiling. When finished applying, give the Classi Plus one last rub all the way round to ensure the perfect seal – paying special attention to the corners.
Step 4
Apply C2 tile adhesive (Find out more about C2) to wall behind Classi Plus upstand. Press upstand into adhesive with the back of the trowel ensuring there are no air pockets.
Following tiling or wall panelling, finish with a Neutral Cure Sanitary Grade 100% Silicone.
Classi Plus is available in 2m, 2.5m, 3.2m and 4m rolls, to be used in an unbroken, continuous run.
