Typical Use

Weathershield Exterior High Gloss is part 3 of a flexible solvent-based system from Dulux Trade specially developed by ICI to give long-lasting, high-gloss protection. It contains a fungicide to inhibit mould growth on the paint film. The results of ICI’s tests show that the Weathershield Exterior High Gloss System will provide extensive protection for up to eight years if correctly applied as per the instructions for use.

The Weathershield System may also be used on metal and plastic surfaces for convenience.

Before preparing any surface for painting, read the Safety, Health & Environmental information on page 2 about old lead-based paints.

Cleaning Up

After use, remove as much paint as possible from brushes before cleaning with white spirit. Do not use or store in extremes of temperature.


Surfaces must be sound, clean and dry before treating.
Remove all loose and defective coatings, if necessary stripping back to bare wood.
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 Dulux Trade Knotting Solution to any remaining knots in the wood.
Prime all bare wood with 1 coat of **Weathershield Exterior Preservative Primer+ 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
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.


Stir thoroughly before use.

Apply 1 coat of the appropriate coloured Weathershield Exterior Undercoat to all primed wood.

Apply a second coat of Weathershield Exterior Undercoat overall, followed by 1 coat of Weathershield Exterior High Gloss.

Allow a minimum of 2 hours before overcoating Weathershield Exterior Undercoat, and 16 hours for 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.
