Polyfilla Professional Interior Timber Filler is ideal for an interior use as a hole, crack, dent, chip, grain and edge timber filler. It dries to a pine finish that can be stained and tinted. Ideal for cracks, nail holes and chips in timber, with a fill depth up to 6mm. Features Fast drying Easy to sand Hard finish with high crack resistance Suitable for stain, tint, paint and varnish Applications Interior use on timber surfaces and edges Application Tips Surface to be filled should be clean and dry with no loose or powdery material. Press filler firmly into dents/holes/split and remove excess. Allow to dry for 2-3 hours in 2-3mm thin applications, depending on humidity. Allow longer drying if painting with solvent based coatings (24 hours minimum) or for deeper applications. Sand with fine sandpaper. For a perfect finish after initial sanding back, apply a thin coat of filler, allow to dry and sand lightly with very fine (400 grit) sandpaper before staining or coating. When tinting or staining, final colour is not achieved until varnish is applied. Prime metals (eg, nail heads) before applying filler. Use Poly Gap filler or silicone sealant where joint movement occurs. Clean up with water before filler dries. Cure product before disposal.
