The technique of dragging is perfect for doors, skirting boards and architraves. If working on such architectural timber, use a 50 mm cutting-in brush (house-painter's brush). A plain door can be transformed into a panelled piece, simply by masking out each panel, dragging and then moving on to the next section.
[edit] Materials
[edit] Oil-based glaze
- one part matt/flat enamel
- one part scumble medium
- one to two parts turps (white spirit)
[edit] Water-based glaze
- two parts acrylic paint
- one part water-based scumble medium (don't use water unless the glaze is very thick)
[edit] Special Tools Needed
- roller to apply glaze
- wall-dragging brush with strong bristles
[edit] Method
1. Dragging requires two people workÂing: one to apply the glaze with a roller and the other to work up the ladder. Roll the glaze evenly onto the wall in strips about 900 mm wide. Roll the outside edge constantly so that the glaze doesn't get a dry edge, this shows as a darker stripe.
2. Jam the dragging brush into the glaze between the cornice and wall and then evenly drag down the wall. If you are on a ladder, just walk down the ladder without hesitating, hesitations will cause irregular stop marks in the finish.
3. As you work down towards the skirting board, feather the brush out, away from the wall. Wipe the brush, turn it over to the other side, jam it into the glaze at the skirting board and pull it up the wall over the same area you have just dragged down.
4. Feather away from the wall near the cornice. This should be enough for good, strong drag marks. Continue around the room until each wall has been dragged.
