Dulux Once Gloss gives a full high gloss finish in a single coat, guaranteed. No undercoat, no second pass. One thick, even coat on primed or painted wood and metal and the job is done.

It works inside and out, so the same tin covers a front door, window frames, skirtings, and railings. This is a solvent-based gloss, which means a proper deep shine but also a 16 hour drying time and brush cleaner rather than water for the clean up.

How to Apply Dulux Once Gloss

1. Remove flaking or defective paint, then sand the surface to take off any sheen.
2. Check the surface is clean, dry, and free from dirt and grease.
3. Prime bare wood or metal first. For exterior work, use Dulux Multi-Surface Primer & Undercoat or a Weathershield equivalent.
4. Stir the tin thoroughly.
5. Apply a thick, even coat with a clean, good quality brush.
6. Do not spread it too far. Stretching the paint is what forces a second coat, particularly over a darker colour.
7. If a second coat is needed, leave a minimum of 16 hours between coats.

Coverage

Up to 12m² per litre. A 750ml tin covers around 9m², and the 2.5L around 30m². As this is a one coat paint, those figures are the finished job rather than a single pass.

Drying Time

Leave 16 hours to dry. Do not close newly painted doors or windows, and do not heat radiators, until the paint is fully dry, or you risk the paint sticking and pulling.

An Honest Word on Yellowing

Dulux are upfront about this, and so are we. Solvent-based paints discolour over time, and the process is faster in rooms with little natural or UV light. A dark hallway or a door behind a curtain will yellow sooner than a bright, south-facing room. If long term whiteness matters more to you than a deep gloss shine, ask us about the water-based Dulux Quick Dry range instead.

Colour

Pure Brilliant White is the only colour Dulux make in this product.

Sizes Available

Made in 750ml, and 2.5L. All three are order in-store only, so please speak to our team.

Cleaning Up

Scrape leftover paint back into a container to reuse. Clean brushes with a proper brush cleaner immediately after use, then let the solids settle so you can pour off and reuse the clear liquid. Air-dry your brushes and store them somewhere dry. Take leftover solids and used cleaner to a hazardous waste facility.
