In this episode Karl from Preservation Virginia's Restoration Crew shows how to reglaze old windows. Karl takes us from examining the window's condition, to replacing glass, reglazing, and painting.
I broke a piece of glass due to concentrating a heat gun on one spot. I used the tape measure upside down and mistook 9 for 6...I learned a lot that day.
Dap 33 is a terrible glazing compound. I would recommend Aqua Glaze or Sarco Type M putty. Also, look for triangle glazing points (sold by CR Laurence, Strybuc and others) which are more suitable than push points.
when you say prime the glaze before painting, does this mean just regular paint primer then paint? I am just doing white, is it ok to use paint and primer in one for outdoors?
I always use oil based primer, not water based latex. The oil based will soak into the wood frame and glaze to adhere well. Top coats of paint can be oil based or latex, but I still prefer oil based because it will flow out well and the brush marks will disappear.
I would like to reglaze a number of old sash windows in the next couple of weeks. I predict the temperatures to be anywhere from 60 to 85°. Can someone tell me which sarco product to use? I will be working outdoors. Also, the sarco products don't require you to use oil based paint do they? Also, how long do I normally need to wait before painting over the glaze? I'm reading anything from overnight to weeks. Thanks!
Hi David! You would have to use Sarco dual glaze putty since you are working outside. The Sarco Multi-glaze type M is only for indoor, out of the weather use. It takes 2 to 3 weeks for the dual glaze to dry enough to be painted. It can be used in the temperature range you stated, as the temperatures rise the putty gets softer and stickier so it's a little harder to tool smooth. From the product literature it can be painted with oil or latex paint after it has "skinned" over.
Many people recommend bedding, however I've almost never come across a single old window that was originally bedded. And the ones I found that were originally bedded had leaded glass.
I’ve been through this discussion with a few “experts”, and they agree that bedding in a tiny rope of glazing then gently seating the glass is the way to insure that moisture from the inside of the room (condensation) does not compromise the exterior glazing. Let’s say the condensation gets behind the exterior glazing and it freezes, it will eventually loosen the exterior seal. Once that happens, moisture (rain water) can enter the cracks and rapidly ruin the whole purpose of a good exterior seal. Yes, bed the glass and use a putty knife to slide off the excess squeeze out on the inside of the window frame. Paint right up on the glass/putty edge a bit to finalize the seal. If I get a tad sloppy and get the paint too far out on the glass, I can wait for it to dry a few days then use a razor blade window glass scraper.
Ok, this guy obviously knows what he is doing. My comment is merely a point of preference. I do not like that style of point at all. I much prefer the flat triangular style. They come with a small tool - a flat piece of metal bent at one end - which is used with a small hammer to drive them in. Merely preference but they work better for me. Also, I put a coat of linseed oil on the bare wood followed by a bead of glazing before setting the pane in place. Once I set the pane I push it down, (careful) with gentle pressure to seat. Then I put the points.
Thank you for all the good info but just a suggestion, I would take out the video still screens with the questions, I feel like it is too distracting, wastes too much time and breaks the continuity of the video, just imo, but otherwise very good!
Great video but the constant stopping to read the text, really interrupted my focus on what you said before and there are some ppl that can’t read, so they have no clue what you are texting across the screen.
Does not look like you are bedding your glass which if correct is NOT an acceptable method. Also need to mention that glazing ledges need to be primed if bare. Also disagree with leaving damaged glazing. It can be steamed out safely or use other acceptable methods
I would rather you do it for me when I push the party too hard to get behind the glass my glass cracked after that I eased up on pressure didn't break any more my Putty was too cold once I learn that should be warmer everything was fine
