How to Paint Doors and Windows


First, remove window catches, stays, door handles and letter boxes. Once splashed with paint these are often difficult to clean.

Doors should be painted in a definite sequence. On conventional panelled doors first paint the mouldings and then the panelled area. The top panel should be painted first, avoiding the door edges and glazing beading. Then paint the lower panel or panels.

The wider sections dividing the panels are called stiles. These are painted next, again working down the door. The top, middle or lock rail, and the bottom rail are- then painted in that order. Paint the inner panels then the stiles on each side.

The edge of the door showing from the painted side should then be painted in the same colour. If the door opens to the exterior the top and, if possible, the bottom edges should be painted to make the timber both weatherproof and waterproof. Water may collect under the door and, through capillary action, be absorbed into the wood which may cause the paint eventually to peel off.

Next, paint the architrave. This order of work helps to give an even coat and cuts down the risk of paint runs and visible lines of demarcation.

Flush doors present a large area which it is difficult to paint in one section. Divide the door horizontally, into three equal sections. Using a 75mm brush, start in the top left hand corner of the door. First, paint a vertical strip, about 460mm wide, then paint another 460mm strip, parallel with the first. Cross brush the two strips evenly into each other and then lay off the paint vertically. This pattern is repeated for the entire door, section by section. Once the three sections are painted, finishing is completed by brushing lightly upwards and downwards to join the sections.

This method requires quick careful work, particularly with some of the quick-drying paints. Once started, the door must be completed in one operation.

Casement Windows

Windows should also be painted systematically. Casement windows may be fixed, or consist of a combination of fixed windows and windows that swing open or out. The closing surfaces of the opening windows should not be painted too thickly as this may cause difficulty in closing. This is most important on metal window frames. Paint the least accessible parts first. Start with the glazing bead, then open the window and paint the top and bottom bar of the window, then the sides of the frame. The hinged upper surface should be painted at the same time as the top bar. Paint the inner faces of the surround to the frame next. Large, opening casement windows are similarly painted.

If the fanlight or long casement window is fixed, paint the glazing beads first, and then the part of the frame facing into the room. Paint the edges, top, bottom and sides, the horizontal bars, the vertical bars and the sill in that order.

When painting windows, use masking tape or a piece of card to keep as much paint as possible off the glass. The glazing putty should be covered with paint, especially on metal frames where moisture may seep between the putty and the frames, causing corrosion. Take the paint to the edge of the glass. If the paint dries on to the glass, use a paint scraper to remove the excess paint.

Sash windows

Start painting with the window closed. Paint the outer sash glazing beads at the top, bottom and sides. Then paint the side frame faces. Next, paint the parting beads but do not apply the paint too thickly. Open the sash and slide it down a little. Next paint the top bar, then slide the inner sash up and paint the lower bar beneath it.

Paint the inner sash in the same sequence as the outer sash, beginning with the beads. Complete the painting sequence as for a casement window. When painting the inner frame surround, first paint the outer mouldings then the upper and lower faces and then the two side faces. Finally, paint the sill.

When decorating a room first paint the skirting and picture rails. Make quite sure they are clean and dust-free and paint the top edge first. Take care not to brush the paint out too hard as the paint covering on the outer curve or edge of the moulding may woi-k thin.


Metal window and door frames should be coated with metal primer. Before priming, make absolutely certain that all rust is removed and that a rust inhibitor has been applied. Badly affected surfaces should be rubbed down with a wire brush, to remove loose rust.

The choice of finishing coat is optional but as this is a vulnerable area a hard gloss paint would give good protection. Metal window frames and doors need to be maintained carefully and regularly. The protective coat should not be too porous. Alkyd undercoats and gloss paints are suitable.

If used externally, lead and copper are rarely painted. Internal plumbing pipes are often painted to improve appearance. After rubbing down with wet-and-dry abrasive paper, wipe down with white spirit to remove metal dust which can be poisonous. Lead pipes and gutterings can be painted with bituminous paint which imparts a rubberized protective surface.

Iron gates and railings should be rubbed down and cleaned off with white spirit. Do not wash them down before painting as water may be lodged in crevices and lead to fresh rusting.
