Surface Preparation

Previously Painted Surface

Remove loose or flaking paint. Remove all traces of grease, dirt, oil or smoke stains using a suitable detergent. Wash with clean water and allow to dry. Repair any cracks or surface defects with a good quality filler. Sand surface until smooth and dust off with a cloth. Glossy surfaces should be sanded to remove gloss. Patchy surfaces require a coat of Australis PerfectPrep (undercoat).

Previously painted surfaces must be sound and have good adhesion. This can be checked by cutting an “X” in the surface with a sharp blade, press a piece of clear tape over the “X” as firmly as possible with the ball of the thumb then as quickly as possible, tear off the tape in one movement. If the previous paint comes off it must be removed before repainting.

Note: Mould, fungal infected surfaces and efflorescence must be treated to eliminate the possibility of recurrence.

Unpainted Paperfaced Wallboard, Fibro, Brick or Cement Surface

Dust down surfaces and apply one coat of Australis PerfectPrep.

Unpainted Fibrous Plaster

Dust down surface and apply one coat of Australis G.P. Oil Based Undercoat or Australis Binder Sealer.
