Before you start

  • Check the surfaces to determine any defects that exist and the tools necessary to fix them.
  • Determine what types of finishes have been previously used on the surface to help you select the correct primer, sealer, undercoat or topcoat required.
  • Clear out the room/area as much as possible to ensure easy accessibility to the surface.
  • Remove any pictures, nails, hooks, curtains, rods, light fittings, door handles and other items that are attached to or near the surface.
  • Arrange all your bulky furniture in the centre of the room and cover it up with a drop cloth.
  • Mask all skirting boards, especially if stained or varnished to protect against paint spots.

Preparing previously painted exterior surfaces

  • Wash with high pressure to remove all dirt, dust, grease and grime.
  • Ensure surface is clean, dry and free from any contamination.
  • Fill up any holes and cracks with a suitable exterior filler and then sand smooth.

Preparing Unpainted Surfaces

New Interior Walls
  • Allow the plaster to cure/set for at least 1 month in summer and 3 months in winter.
  • Conduct a Tape Test by applying masking tape firmly to the plaster surface and then quickly pull it off.
Exterior Clay Bricks
  • Remove any loose particles by dry brushing the surface.
  • Fill any holes and cracks with a suitable filler.
  • Wash the surface if necessary with a solution of water and household detergent.
  • Rinse with water and allow it to dry thoroughly.
  • Apply Deluxe Coatings Super Seal. Leave for 24 hours and then apply a second coat.
Gyprock
  • Ensure joints are smooth and surface is dust free.
  • Apply Deluxe Coatings Acrylic Undercoat to seal the surface.
Particleboard/ MDF
  • Remove any dirt and grease from the surface.
  • Fill all the edges or get them fitted with an edge strip.
  • Make sure all holes are filled before sanding.
  • Seal the surface with Deluxe Coatings Acrylic Undercoat before painting.
  • Do not use oil based undercoats on fibre boards.
Interior timber
  • Remove all dust and dirt from the surface.
  • Sand smooth the surface before you start painting. Timber should be sanded along the grain to prevent any fibres being raised.
  • Use Deluxe Coatings Acrylic Undercoat or Deluxe Coatings Super Seal to seal the surface.
Exterior timber
  • All edges should be slightly rounded by sanding or scraping.
  • Any soft material on the surface should be scraped clean.
  • If the timber has been exposed, damaged, has cracks or holes, then it should be filled up with Builders Filler (2 pack) and re-sanded.
  • All sanding should be carried out with the grain.
  • Wash or dust off as necessary prior to painting.
Concrete
  • Concrete should be allowed to dry for at least 12 weeks before painting. If any wetness remains, the moisture can cause blistering or peeling of the coatings later on.
  • Fill all unwanted holes in the surface with suitable filler.
  • If needed, wash surface with a solution of Water (2 to 18 litres) and Hydrochloric Acid. This will help achieve a clean etched surface before painting.
Cement render
  • Surfaces must be cured and allowed to dry before painting. At least 6 weeks for oil based paints and 4 weeks for acrylic paints.
  • If any mould has formed, treat it with a solution of Deluxe Coatings Fungicide and water (2 to 18 litres).
Galvanised Steel and Zincalume
  • New metal should be thoroughly de-greased by wiping with a de-greaser and rinsing the surface thoroughly.
  • Structural galvanised steel (pipes, beams, hand rails etc) must be thoroughly abraded by sanding or grinding to remove any chemical treatments from the surface and ensure adhesion of coatings.
  • Use Deluxe Coatings Acrylic Undercoat to prime the surface, then you can apply Deluxe Coatings Gloss Acrylic or Deluxe Coatings Gloss Enamel.
