Overview

High gloss, weather resistant Dulux Trade Weathershield Exterior High Gloss is the 3rd part of a 3 part flexible paint system specifically developed by Dulux to give long-lasting protection for exterior woodwork. The fungicide contained within the paint inhibits mould growth on the paint film and helps it stay cleaner for longer. Can be used on primed metal and plastic as well as woodwork. Use with Dulux Trade Weathershield Exterior Flexible Undercoat

Preparation

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, stripping back to bare wood if needed. Pre-1960s paint surfaces over wood and metal may contain harmful lead, so take special precautions. 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). Do not inhale 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. Wipe off excess primer from 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 base coat, also called a dual-purpose primer. These materials may need to be re-primed as they erode quickly.

Application

Note: always read and follow the manufacturer's instructions found on the tin.

Stir well before use. Apply 2 coats of Weathershield Exterior Flexible Undercoat in the appropriate colour, to all primed wood, followed by 1 coat of Weathershield Exterior High Gloss. Where a special process colour is to be used, or where there is a strong colour change, more coats will be needed.

Resinous wood or woodwork with a history of blistering should be painted with light colours only, particularly on south facing elevations. Use as directed above on good quality timber that conforms to BS EN 942: 1996, in conjunction with good component design. For best colour consistency, purchase sufficient tinted paint for each job including touch-in at one time from the same source.

Apply with a brush only. For health and safety reasons relating to solvent based paints, Dulux Trade Weathershield Exterior High Gloss should not be sprayed.
