Another reason to allow the putty to harden for at least 24 hours is to prevent a hard brush from deforming the putty while painting over it. Otherwise the oil in the putty acts as a contaminant to any water based or other non-compatable coating and prevents it from adhering properly. This allows the surface to harden a little and the solvent or vehicle has out gassed enough to allow the coating to adhere properly. I always wait 24 hours for the putty surface to harden and cure before painting or using any other coating. I did not realize that they are making it into a putty now. Sorry for the confusion, but I always thought that the glazing material was used as a coating in the repair of pottery and glass items. My original questions was about how long, under ideal conditions, should one wait before priming linseed oil putty.ask five people and get five different responses. For window restoration, however, I prefer to used Abatron's LiquidWood and WoodEpox. I too use Durham's rock hard putty at times. I have used it to restore a bow window that was destroyed by water and it held great.ĪquaGlaze and other soy based glazing putties are advertised as window glazing putty. It can be used outdoors but must be painted. This stuff expands when it dries and holds on tight. If you need a really good filler that holds very well use Durham's water putty. Any putty with a drying oil in it is good to use. The idea is that the boiled linseed oil is a drying oil and needs to dry a little to prevent the surface from being hostile to any coating applied. I think there is no other solution then to let the putty age a little before applying any coating. I use putty, and other fillers, all the time. He may be saying to use it as acoating over the putty instead of any kind of primer. Aqua Glaze is a glazing compound used for ceramics, walls, etc. I do not understand what the Savogran Chemist is trying to tell you. I too use Zinsser fast drying and sealing primer, but purchased Sterling's Prime It per suggestion of their chemist. Wonder if there'll be anyone at the Expo who can answer the question (honestly) about Aqua Glaze's performance over the long haul?
Like our old windows, linseed oil has proven itself over many generations. That struck me as something a salesperson would say.OTP had a linseed oil base and AG has a soy oil base. When I spoke with the chemist at Savogran (they purchased Sterling) about the prospects of manufacturing Old Time Putty he told me that theywould no longer make it but that I should try Aqua Glaze which he claims is very similar.

#Durham rock putty crack
The Zinsser oil primer is pretty good and dries quickly, but if the putty isn't quite cured, the primer will crack and then we just have to put another coat of top paint on which doesn't improve turn time.Īnyone have long term experience with water based putty? We have used the Aqua Glaze from Sterling Lurton, but I'm not sure about it's performance over years of weather exposure.
#Durham rock putty windows
I find waiting for the "skin" the most frustrating part of the biz as I want to get the windows done and get paid for them! I haven't tried a fan on them yet, but it's a good idea. Posted: Thu 12:56 pm Post subject: Glazing putty Yes, I too use a fan and.a woodstove in the winter.and a dehumidifier in the summer. This can reduce "skinning over" time from weeks to days.īy pen and thought best words are wrought Warm air also promotes the oxidizing chemical reaction. The constant flow of air over the surface of the glazing oxidizes the oil in the putty faster than still air. When we're in a "hurry" we stack the sash with sticks between each one making a space between each sash and then set up a fan to blow air through the stack. I'd like to hear feedback from folks on what works for them. I find the primer is almost water thin with very little pigment which means I may need to use two coats OR prime putty with Prime-It and the wood with another heavier primer. I purhased their Prime-It product that the chemist said was made specifically to prime over their putty. The chemist at Sterling-Clarke (now out of business, see posts on this forum), the makers of Old Time Putty, suggests 48 hours in good dry warm air.
#Durham rock putty skin
I prefer to time my projects so that the putty has about a week to skin over. I know of some folks who prime the same day, wait a week to 10 days and someone who waits up to 30 days. Most manufacturers suggest waiting for a 'skin' to form on glazing putty prior to priming it. Guess I'll be the one to try and get another conversation going.
