Before you start    Resurfacer8.8.pdf

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.

Gyprock

Ensure joints are smooth and surface is dust free.
Apply Huecoat Acrylic Sealer Primer Undercoat to the surface.

Interior Exterior 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 fibers being raised.
Use Huecoat Acrylic Undercoat or Huecoat Timber Seal to seal the surface.
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.

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.
