A fine surface, ready mixed Filler from leading brand Tetrion, designed to fill the unevenness of wood grain, hairline cracks and chips in your paintwork. It is formulated using ultra-fine filler which enables the filler to be drawn out without breaking up, leaving you with a super smooth finish. Only a thin layer is necessary (no more than 2mm) so it takes just 30 minutes to dry, requiring minimum sanding, if at all necessary. It is suitable for internal and external use and is ideal for most building materials.
