Painting window frames can have several reasons. You want to get rid of the wood look, you think it’s time for a new colour or the window frames that have already been painted can get a refreshment. Whatever the reason, painting inner frames is time consuming. But, besides that, it is also very satisfying when the window frames are painted.
- Lacquer paint
- Coarse sandpaper (80 grit paper)
- Medium coarse sandpaper (120 grit paper)
- Fine sandpaper (320 grit paper)
- Masking tape
- Round paintbrushes
- Paint roller with paint bracket (narrow)
Step 1: repair and degreasing
Do you have old window frames? Then there may have been wood rot. If the window frame has rotten parts, it is wise to remove the rot. You can remove the rot with a chisel. To repair damage you can add wood rot stop and wood filler to the frame.
Don’t the window frames have wood rot? Then degrease the window frames.
Step 2: Sanding
After degreasing, it is important to sand the frame. With the right sandpaper you can make old paint residues disappear and give the window frame a convenient initial layer.
- Coarse sandpaper (80 grit paper): useful for the damaged parts of the frame.
- Medium coarse sandpaper (120 grit paper): suitable for frames made of untreated wood.
- Fine sandpaper (320 grit paper): suitable for a treated frame, without damaged parts.
Step 3: dust removal and masking
When sanding the frame, a lot of dust is released. Therefore, use the sot vacuum cleaner and a cloth for a while. After this you can tape the window frames and windowsill.
Step 4: start with priming
First of all, stir the paint with a stirring stick. It may also be useful to shake the dense paint pot vigorously beforehand. Dip the round brush into the paint and apply the primer to the entire frame.
Step 5: cleaning primer
As soon as the primer is clean, it may be wise to use fine sandpaper (320-grit paper) to sand the frame. Then clean the frame again with a degreaser.
Step 6: finally start painting
When the frame is dry from cleaning the primer you can finally get to work. We recommend using acrylic lacquer for the frame. Dip the brush in the lacquer and first iron along the edge of the can. Then apply the paint to the frame.
It is best to first paint the corners and edges of the windows. After that you can continue painting the long parts of the window frame.
Step 7: Checking and finishing with the paint roller
Before the paintwork is dry you can check it with a narrow paint roller. This ensures that the paint layer is more beautiful and even on the frame. By using the paint roller you also avoid any dripping.
Tip: Apply a minimum of 2 coats of paint for optimal coverage. Let the paint dry in between and sand the first layer lightly with fine sandpaper or a scouring sponge. Both have 320 grit sandpaper.
