It was ready for paint in about 4 days which was great, but it was a little chalkier than I was used to with Type-M. Glazol seemed to me to be somewhere in the middle of Type-M and DAP 33. It has been around long enough and has been tested enough that I feel comfortable putting it on my windows too. I tried a gallon of this at a friend’s urging and found that it works rather well. It may not be my main putty, but it is invaluable for those special cases. It has to be mixed thoroughly before being used, otherwise it can be pretty sticky. Of all the putties here, it is probably the most temperamental to work with.

It can be ready for paint in as quick as 1 hour! This can be a big help if you are in a time crunch. The thing that makes Aqua Glaze special is its super fast curing time. I keep a can of this around the shop for special circumstances. Unlike the other oil-based putties, so far, Aqua Glaze is an acrylic glazing putty. It’s neither here nor there for my tastes.

The curing time until it was skinned over and ready for paint was closer to Dual Glaze in the 2 week range, though slower in cold temperatures, which was one of the reasons I quit using it. I found it a little bit chalkier than Type-M, but just as easy to work with. I used it sparingly at the start of my business since it was easy to find. Good ole’ DAP 33 is available at almost every hardware store, which is one of the reasons I think so many people use it. But that slow curing makes for a putty that stays flexible much longer than most of its competitors. The downside is that it takes a long time to cure (2-3 weeks). Dual Glaze is almost identical to work with as Type-M, except that it’s a bit oilier which makes it a little messier to work with, especially on hot days. This makes it a good choice for spot glazing touch ups outside. This is the first putty I learned to use because it can be used almost anywhere! It is designed for wood OR steel windows and can be applied outside or in a shop. Sarco has been making putty for a long time and they have a lot of different varieties of which Dual Glaze is one of the most versatile. Despite this, I have had decent success using it sparingly outside as long as I get it painted in the 3-5 day range after application.

It is only recommended for glazing in a shop and is only for wood sash (not for steel windows). The putty is also fast to skin over, which means it is ready for paint (in most conditions) in as quick as 3-4 days. It is relatively easy to use, not too oily, or too dry and tools to a nice smooth finish. This is the most common glazing putty that professional window restorers use and it’s what my shop uses about 90% of the time. The Sarco putties are sold right here on The Craftsman and other putties are affiliate links, which means I get a small commission at no extra cost to you if you decide to buy the putty, but don’t buy unless you think it is the right one for you! I’ve also included links for each glazing putty, so you can purchase them if you’re interested. So, I’ve put together this list of my six favorite window putties to help you in your search. All of these putties will help you get the job done right, it just depends on your personal preferences and situation as to which will be the best putty for your project. A lot depends on the type of window and where you will be doing your gazing (outside or in a shop). There are a lot of options when it comes to finding the right window glazing putty for you.
