If your windows aren’t looking their best, they might need a little bit of TLC to stay protected against the weather elements. Here is a guide to show you how to breathe new life into your windows and trim with Dulux Aquanamel.

What you'll need:


  1. Let’s get started. Choose a sheen level that suits your home. Semi Gloss is the perfect complement to low sheen walls, or you may look for a distinct Gloss  finish
  2. Select your chosen colour. You can use the Dulux colour chips to closely match the existing paintwork on your windows, or try a new colour to refresh the look.
  3. Before you start painting, lay down a drop sheet and start prepping your windows.
  4. Windows are one of those places in the home that collect dust and cobwebs, so be sure to give yours a good clean with Selleys Original Sugar Soap before painting. Read the Interior Paint Preparation Guide to get your windows in the right condition to paint.


Dulux Aquanamel is a durable, non-yellowing, water based enamel paint that is low odour, fast drying and has easy water wash up.

It is important to test the adhesion on all previously painted surfaces by cutting a small ‘X’ through the existing paint with a sharp blade, press cellulose tape firmly across the cut and then rip off the tape. If the paint comes off, it is unsound and should be removed.

  1. Mask around your window frame and glass with tape to prevent accidental splatters interfering with your walls or view.
  2. The last step in prepping your windows is to apply a good quality undercoat. Paint your windows with one coat of Dulux 1Step Prep and then leave to dry for at least 2 hours.
  3. Stir your paint thoroughly using an up and down scooping motion. Dip your brush halfway into the paint and tap it against the side of the pot to remove any excess. Working quickly, paint next to the glass around the sills first using short horizontal brush strokes. Avoid dabbing the paint.
  4. Workaround the window frame progressively outwards until you finish with the edge against the wall.
  5. For best results, lightly go over the wet area you’ve just painted using long brush strokes, then leave to dry. This will help achieve a smooth finish.
