Window Glazing Tip {Video}

I have a quick tip you need to know if you’re going to do some window glazing. After you get your windows glazed you’ll likely have an oily residue all over the glass from the putty. If you wait an hour or two this residue will dry and be very difficult to remove. Many glaziers use whiting to clean their glass, but I use something cheaper and easier to find.

Check out my video tutorial below for an easy way to get your windows cleaned and ready for paint. As a bonus, this tip will save you from possibly messing up your perfect putty in the cleaning process!

    I just came across your website on this page searching for “window glazing tips”, as I am repairing a couple of windows with multiple pieces of triangle and diamond shaped pieces of glass, and I find it slow and difficult to make it look good.
    One problem I have is that the putty often “pulls up” and leaves an uneven surface. Is that from pushing too hard, not hard enough, the putty too dry, too oily?
    If the surface is uneven, can one go over it after it has skinned over some, so one can shape it but not disturb the surface?
    I saw another person’s blog mention that they use oil base stain killer over putty more or less after they finish and that they can then paint over that, without waiting 7-10 days. Ever heard of that?
    Both windows are hinged and open either out or in. I see where you say do not paint top, bottom, and sides of a typical window, but what about windows that are not slide up and down?
    I am in the midst of ongoing deferred maintenance and restoration of our ~1895 Queen Anne Victorian and will devour your site in the coming days and weeks.

  2. Great idea, Scott! Not only cheaper than whiting, but most DIYer’s probably have a bag of sheetrock compound laying around anyway!

    • That’s the idea! Why pay more when you don’t have to? :)
