  • Why is it important to apply the full system?

    Applying the whole system ensures you get full depth of colour, durability, eight years of protection and the full high gloss sheen.

  • Is this product fully water-based?

    It’s an alkyd emulsion meaning it’s a water-based paint that acts like it’s solvent-based – higher sheen level, increased flow and increased levelling to reduce brush marks.

  • Can I use the product interior as well as exterior projects?

    No. The product is for exterior use only because it contains fungicide, which helps stop mould growth on the surface of the paint film.

  • How does it compare to its solvent-based alternative?

    Very well, both in the way it feels when applied and in the way that it looks. The improved sheen level – something water borne products don’t always deliver – is a particular strength.

  • Is it covered by the Dulux Promise?

    Yes, this product is protected by the Dulux Promise.

What’s the best way to prep the surface?


Look where the knots are and add two coats of knotting to those areas, being careful not to over apply. Make sure the surface is dust free and any obvious stains are removed. Sand down any sharp edges, then apply two coats of Preservative Primer, following the on-pack instructions.

Hardwood doors

While we don’t specify using Preservative Primer because the wood is so dense, it’s worth checking that there are no surface oils present. If there are, wipe away with a clean cloth and methylated spirits.

Previously painted surfaces

Wash down well with a sugar soap solution then make sure to rinse well with clean water. Once the surface is dry, abrade it either with power sanding or some hand sandpaper. This helps get rid of any blemishes or previous application marks and also provides a key so our water-based system can anchor to the surface.
