Ready Mixed Filler is very easy to sand down when overfilled.  With no need to spot prime.  It will not flash or grin and resists slumping.  Suitable for internal use.
Can be used on new or renovated substrates, either unpainted or painted: gypsum plaster, plasterboards, old painted surfaces, cement, concrete, cellular concrete, breeze blocks, bricks and stone.  Can be painted over in 12-24 hours.  Overcoat with any conventional paint or wallpaper.
