Polycell Polyfilla Mendall 90 is a white, ready-mixed resin bound filler in paste form. It provides tough, flexible weather resistant filling on both interior and exterior surfaces. Designed for filling cracks and holes in and around plaster, wood, brick, stone, concrete, stucco, metal, glass, fibre-cement and other masonry surfaces. It is specifically formulated to fill cracks that might be unstable due to normal expansion and contraction as a result of temperature changes, but is not recommended for structural cracks. Polycell Polyfilla Mendall 90 is also ideal for filling cracks where adhesion problems occur, e.g. the join between cornice and wall or ceiling where conventional crack fillers will fail. The extra adhesion and flexibility of Polycell Polyfilla Mendall 90 ensures that the filler will not fall out. Other uses include the repair of glazing where old putty has cracked or fallen out and stopping of interior or exterior wood floors and fascias. If it is to be used under a clear varnish, Polycell Polyfilla Mendall 90 may be tinted to the desired timber colour with iron oxides.
