Select Schluter-RENO-T according to joint width, to ensure proper support of the lateral crosspiece.
The joint cavity must be at least 3/8″ (9 mm) deep and free of debris. Substances that inhibit adhesion must be removed from the sides of the joint.
Fill the joint with elastomeric sealant such as Schluter-KERDI-FIX or similar. Then insert the vertical leg of Schluter-RENO-T in the joint so that the lateral crosspiece rests completely on the edges of the surface coverings.
Remove any excess sealant with a suitable cleaner
