  • Film Thickness :
  • Film thickness will be dependent on the coverage achieved.
  • Wet: 62 microns
  • Dry: 27 microns
  • Composition (nominal) :
  • Pigment: Lightfast Pigments.
  • Binder: Acrylic Copolymers plus Alkyd and Fungicide.
  • Solvent: White Spirit and Low Odour Aliphatic Hydrocarbons.
  • Apply 2 coats of the appropriate coloured Weathershield Exterior Flexible Undercoat to all primed wood, followed by 1 coat of Weathershield Exterior High Gloss.
  • Where a special process colour is to be used, or where a strong colour change is required, additional coats will be required (see appropriate Dulux Trade colour card).
  • When painting resinous wood or woodwork with a history of blistering, it is advisable to use light colours only, particularly on south facing elevations.
  • The maximum benefits of this system will only be realised when used as directed above on good quality timber that conforms to BS EN 942: 1996, in conjunction with good component design.
  • To get the best results, ensure surfaces to be painted are sound, clean and dry (new surfaces particularly must be fully dry).
  • Remove all loose and defective coatings, if necessary stripping back to bare wood.
  • Special precautions should be taken during surface preparation of pre-1960s paint surfaces over wood and metal as they may contain harmful lead.
  • Remove and treat any mould, algae, lichen or moss with Weathershield Multi-Surface Fungicidal Wash.
  • Remove defective glazing material, clean the rebates and any loose or open joints. Replace any rotten wood and troublesome knots with new timber.
  • Thoroughly rub down all surfaces to remove any grey, weathered wood and surface sheen from remaining coatings, and then dust off (refer to your COSHH Assessment).
  • Avoid the inhalation of dust. Wear a suitable face mask if dry sanding.
  • Apply 1 or 2 coats of an appropriate knotting solution to any remaining knots in the wood.
  • Prime all bare wood with 1 coat of Weathershield Preservative Primer+ (BP)**, including any new or bare replacement beading. Excess primer should be wiped off surrounding paintwork. Prime any bare metal with 1 coat of Dulux Trade Metal Primer
  • Fill any surface defects, open joints etc. and replace any missing glazing material.
  • New joinery is often factory primed using a stain basecoat (also called a dual-purpose primer). These materials quickly erode when left exposed and may need to be re-primed.
  • Brush only. For Health Safety reasons relating to all solvent-based paints, spray application is not recommended.
  • As with other solvent-based paints, do not use in temperatures below 5ºC (as recommended by British Standard BS 6150).
  • Cleaning Up :
  • After use, remove as much product as possible from equipment before cleaning with brush cleaner
