Surfaces

Ensure surfaces are sound, dry, clean and free from loose and flaking materials, wax, grease and polish. Remove any loose or flaking materials.

Preparation

For bare wood: Ensure the wood is dry and in good condition. Any grey or denatured timber will need sanding back to a clean smooth surface. Smooth and round off sharp edges.

For previously painted surfaces: All surfaces must be clean, dry and free from anything which may interfere with the adhesion of the materials to be applied. Wash with warm detergent solution, rinse well with clean water and allow to dry.

Abrade with wet and dry abrasive paper to remove any surface contamination and provide a key. Avoid the inhalation of dust Wear a suitable face mask if dry sanding.

For metal surfaces: This system can be applied to suitably primed metal surfaces. Do not apply if there is a risk of rain or if air/surface temperature is likely to fall below 8°C or when the relative humidity is above 80% during the application or drying period.

  • Apply by brush or roller evenly and liberally without overspreading.
  • To the prepared surface apply one coat of Sandtex Trade Flexible Primer Undercoat followed by one or two coats of Sandtex Trade Flexigloss X-tra or Sandtex Trade Eggshell X-tra as necessary.
  • Some strong colours may require an additional coat to ensure complete obliteration.
  • On redecoration where the colour is unchanged,  Sandtex Trade Flexible Primer Undercoat is not required.
