Unique Properties of Polycell Polyfilla Mendall 90

Polycell Polyfilla Mendall 90 is meticulously formulated to address unstable cracks that may shift with temperature fluctuations. However, for structural cracks, it’s advised to seek other solutions. This filler is particularly potent for filling areas where standard fillers fail, such as the join between a cornice and a wall or ceiling. Its heightened adhesion ensures it stays put. Other applications range from repairing glazing where old putty has cracked or fallen out, to stopping of interior or exterior wood floors, fascias, etc. If you wish to use it under clear varnish, tint it with iron oxides to achieve your desired timber colour.
