Join Stefan J. as he shows you step-by-step how to renovate old windows, from how to remove the glass and scrape off old paint to how to putty windows with real linoleum putty and finally how to paint the new, fresh window frames.
In the video you can see two different windows renovated in the same way. Many people involved in window renovation and building maintenance probably have their own little tricks and ways of doing things, but in general, this is what the window renovation process looks like from start to finish:
- First, remove the old linoleum putty with a scraper or putty knife. It's easier if you heat it first.
- Then the pins that hold the glass in place are loosened, so that it can be lifted out.
- When all the glasses are removed, the paint is scraped off using the heat lamp.
- Then the fittings are removed.
- Now the entire window frame is sanded with sandpaper.
- The lower part of the window arch has rotten wood, which is common with old windows. So Stefan knocks out the wooden dowels that hold the arch together to replace the damaged wood. In this case, it was enough to replace just part of the wood, and new, fresh wood was joined to the old. New wooden dowels are driven in, and now the window renovation continues!
- Fittings are cleaned of old paint and attached to the unpainted window frame.
- The entire window frame is oiled with a coat of raw linseed oil paint. This makes the wood more resistant to moisture and rot, and also saturates the wood, which is important when applying linseed putty. Otherwise, there is a risk that the dry, old wood will soak up the linseed oil in the putty, causing the putty to crack and release from the wood.
- The old window panes are polished and scraped clean of old paint.
- Linoleum putty is placed in the arch underneath where the glass will rest, to make it really tight.
- New glass is cut with a glass cutter.
- The glass is pressed into place and secured with new pins that are hammered in carefully.
- As a final seal, linoleum putty is applied and trimmed with a putty knife.
- Any putty is scraped off the inside of the window.
- Chalk is powdered on the squares to remove grease from the linoleum putty.
- The slots and holes with the wooden plugs in the window frame are also sealed with linoleum putty.
- Finally, the window is painted with three coats of linseed oil paint
Material used in the video:
- Speedheater Cobra heat lamp (also works with a simpler heat gun)
- Paint scrapers from Speedheater and Bahco (a profile scraper comes in handy when renovating windows)
- Crude linseed oil (to impregnate and saturate the wood before painting)
- Linoleum paint from Wibo Färg
- Linoleum putty from Dana
