How to Paint Doors and Window Frames
Painting the Door
Doors have a variety of faces, edges and mouldings that need to be painted separately, yet the end result must look even in colour, with no ugly brush marks or heavily painted edges. Recommended procedures for painting different types of door will help you achieve those ends.
Remove the door handles and wedge the door open so that it cannot be dosed accidentally, locking you in the room. Keep the handle in the room with you, just in case. Aim to paint the door and its frame separately, so that there is less chance of touching wet paintwork when passing through the freshly painted doorway. Paint the door first, then when it is dry finish the framework.
If you want to use a different colour for each side of the door, paint the hinged edge the colour of the closing face (the one that comes to rest against the frame). Paint the outer edge of the door the same colour as the opening face. This means that there won’t be any difference in colour when the door is viewed from either side.
When painting up to the edge of a door or window frame, brush from the centre out: if you flex the bristles against the edge, the paint will run.
Brushing across mouldings tends to flex the bristles unevenly and too much paint flows: spread the paint well, taking special care at the corners of moulded panels.
Painting a flush door
To paint a flush door, start at the top and work down in sections, blending each one into the other. Lay on the paint, then finish each section with light vertical brush strokes. Finally, paint the edges.
Painting a panelled door
Whatever the style of panelled door you are painting, start with the mouldings followed by the panels. Paint the muntins next, then the cross rails. Finish the face by painting the stiles. Finally, paint the edge of the door.
Painting a Door Surround
Each side of the frame should match the corresponding face of the door. Paint the frame in the room into which the door swings, including the edge of the stop bead against which the door closes, to match the opening face. Paint the rest of the frame the colour of the closing face.
Paint the architrave and doorframe up to and including the edge of the door stop one colour. Paint the face of the door and its opening edge the same colour.
Paint the architrave and frame up to and over the door stop the second colour. Paint the opposite face of the door and its hinged edge with the second colour.
Paint the glazing bars first, then the cross rails, and finish by painting the vertical stiles.
Painting Up to Glass
When painting the edge of glazing bars, it is usual to overlap the glass by about 2mm (1/16in) to prevent rain or condensation seeping between the glass and woodwork. However, if you find you can’t make a neat job of it, try one of the following tips.
To achieve a satisfactory straight edge, use a proprietary plastic or metal paint shield, holding it against the edge of the frame to protect the glass.
Alternatively, run masking tape around the edges of the pane, leaving a slight gap so that the paint will seal the join between glass and frame. When the paint is touch-dry, carefully peel off the tape.- Don’t wait until the paint is completely dry, or it may peel off with the tape.
Once it has set, use a sharp blade to scrape off any paint that has accidentally dripped onto the glass. Many DIY stores sell plastic handles to hold disposable knife blades for this purpose.
Painting a Casement Window
A casement window is hung on hinges and opens like a door, so if you plan to paint each side a different colour, follow a similar procedure to that described for painting doors and frames. Window frames need to be painted in strict order, so that the various components will be evenly treated, and also so you can close them at night. You also need to take care not to splash window panes with paint or apply a crooked line around the glazing bars — the mark of poor workmanship. Clean the glass in your windows before decorating to avoid picking up particles of dust in the paint.
Removing the handle and stay
Remove the stay and window catch before you paint the casement. So that you can still operate the window without touching wet paint, drive a nail into the underside of the bottom rail to act as a makeshift handle.
Make a temporary stay with a length of stiff wire wrapped round the nail — hook the other end and slot it into one of theholes in the frame.
Applying the paint
First paint the glazing bars, overlapping the glass on each side. Carry on with the top and bottom horizontal rails followed by the vertical stiles. Finish the casement by painting the edges, then paint the frame.
Painting a Sash Window
Sash windows are more difficult to paint than casements, as the two panes slide vertically, overlapping each other.
The following sequence describes the painting of afrom the inside. To paint the outside face, use a similar procedure but start with the lower sash. If you are using different colours for each side, the demarcation lines are fairly obvious: when the window is shut, all the visible surfaces from one side should be the same.
Following a logical sequence
Raise the bottom sash and pull down the top one. Paint the bottom meeting rail of the top sash and the accessible parts of the vertical members. Reverse the position of the sashes, leaving a gap top and bottom, and complete the painting of the top sash. Paint the bottom sash, then the frame except for the runners in which the sashes slide.
Leave the paint to dry, then paint the inner runners plus a short section of the outer runners, pulling the cords aside to avoid splashing paint on them, as this makes them brittle. Before the paint dries, check that the window can slide.
