How to Paint Stained Glass Window Frames

How to Paint Stained Glass Window Frames

To keep your stained glass windows looking their best and to help them last for many years to come, you will need to ensure that their frames are well maintained and regularly repainted.

A fresh coat of paint can really help to uplift the look of your windows and your home. If you fancy a change, you could choose a new shade rather than the usual white or cream. Antique greens and blues look especially stylish and can help to bring out the colours in your stained glass design.

To help you get started we’ve put together this step by step guide to painting stained glass window frames…

What you will need:
Clean cloth and water
Masking tape
Small, old plastic container (for your paintbrushes)
Water-based wood primer
Good quality paint (water-based is best as it is less toxic and works well on timber)
Selection of narrow paintbrushes
A toothbrush
Step 1: Cleaning
Begin by carefully cleaning the windows and frames. Gently wipe over the stained glass panels with a soft, damp cloth – Note: It is important not to use any harsh chemical cleaners on stained glass. Instead use a pH neutral solution mixed with water.
For the frames you can use a clean cloth and plain water, unless they are very dirty, in which case some sugar soap will really help to break down the grime.
Step 2: Sanding
Once dry, you can begin sanding the window frames. This helps to helps to remove any stubborn dirt and creates a rough surface to help the new paint stick.
To ensure a really good finish, work a few inches at a time and feel the areas with your fingertip to make sure you have a smooth surface.
Step 3: Dusting
It is important to ensure that there is no dust left behind after sanding. This is because it will ruin your smooth paint finish. Use a paintbrush to sweep away the main areas of dust and a toothbrush for the smaller corners and cracks. A hand-held hoover is also really handy for clearing away any remaining dust.
Step 4: Preparation
Masking tape is the secret to beautiful, clean lines when painting and it is also great for protecting delicate surfaces such as stained glass. Tape off the edges of your windows making sure you get it tight into the edges. You can also cover handles and locks with masking tape or remove them before painting.
Step 5: Primer
Once your stained glass windows are taped up, you’re ready to prime. Any areas of bare wood should be primed with a water-based wood primer to give the best results when applying your paint.
Step 6: Painting
Once the undercoat is dry, it’s time for your first coat of paint. Begin in one area and work away from this point until you complete a ‘circle’. Your final layer of paint should give a beautiful finish to your window frames and only when they are completely dry should you remove the masking tape or replace any fixtures.
