Ensure surface is dry and free from loose material. Rub down gloss surfaces.


Touch in nails and screw heads with oil based paint and ensure all wiring in insulated.


Stir to a creamy consistency.


Apply with a filling knife, trowel or float with upward sweeping strokes. Maintain a firm, even pressure.


Do not fill more than 50mm in one application.


Gently smooth off with a clean, wet float, cleaning and wetting the float between strokes. Alternatively use a length of straight wooden batten, drawing it gently across the surface, wetting as required.


Once the surface is firm but before it dries hard, re-wet and polish with a clean float for a smooth finish.


Allow to dry for at least 24 hours (several days for deeper repairs).


Replace lid firmly and wash tools in warm water.
