When and where is JOINT FINISHER used

JOINT FINISHER is ideal for repairing defects, cracks and other flaws on the surface. It is also suitable as a base layer under tiles, wallpapers or as a full-area final screed to achieve perfectly smooth surfaces.

Application video

The substrate must be free of dust, grease and dirt. Glazy surfaces should be cleaned well. Before application, light sanding with a suitable abrasive material is recommended. New layers of plaster or masonry must be cured before application. Mix manually or using a blender at low speed (<600 rpm). Apply the mixture using a stainless steel trowel. The maximum coating thickness should be 3 mm. When the product is dry, it can be smoothed with a grinding wheel.
