How to paint window trims

Preparation is a must. Firstly, wash the windows and trims with sugar soap using a clean cloth or sponge. Scrape off any loose paint and fill any gaps. Then sand the window frame or trims. Don’t use pressure — let the paper do the work. Remove any sanding residue with a damp cloth. Mask the areas above skirtings and around door and window frames with tape to avoid getting paint on the surrounding walls, and use a drop sheet to protect flooring. See more prep tips here.

If you’re painting bare timber, or the surface is stained or damaged, you’ll need an extra layer to prime the surface. British Paints PREP 4in1 Water Based combines the functions of sealer, primer, undercoat and stain-blocker in one convenient product.

Stir your paint with a flat stirrer or old ruler. British Paints Oil Enamel Gloss (or Semi Gloss) is the pick for window frames and interior trims. It’s what you choose when a pro-smooth, tough finish is required. (See more about enamel paints here.) If the surface doesn’t need a primer, you can jump straight in with British Paints Paint & Prime Doors, Windows & Trim. Remove excess paint by tapping the brush on the side of the can. Start in a corner and paint quickly using long strokes (no dabbing!). If you’re painting a window frame, don’t worry about getting paint on the glass — once it’s dry, it’s easy to scrape off.

While your paint is still damp, ‘lay off’ the surface using an unloaded brush and a very light touch. Use long, smooth strokes to smooth the surface and produce flawless results. Allow a minimum two hours between coats and leave windows and doors open for 24 hours to avoid sticking.
