Sarco Type M Glazing Putty (Quart)

Amazing product! Well worth the money!

I have a 100 year-old house and redid some of the windows (glazing putty, window weight cords, paint, brass hardware) shortly after I bought it 40 years ago. I've just retired and need to address some of those windows again plus others that have not been touched since who-knows-when. I have been dreading this project and put it off until I retired this summer. While checking out glazing putties on the web, I discovered Sarco Type M and decided to try a container. I am glad I did! It, along with the calcium carbonate whiting powder, are MUCH easier to use and produce a much better result than the other types of glazing putty I have tried and are well worth the additional price. Be sure, however, to watch the associated videos for tips on how to do the job.That still leaves the most miserable part of this work, removing the old putty without breaking any glass. I plan to build a steam box and try a hacking knife in the hope that one of these works better that the techniques I have been using, which are tedious, tiring and not very thorough.

Sarco is the best. DAP is the worst. Says this WPA member. Here's my advice: 1) pick a product like this one that has a general consensus as being the best. 2) Acknowledge that the first time out, you might not get it right. 3) invest in learning its properties despite messing up initially, in order to unlock its greatest potential over the course of time. 4) enjoy the superior quality of your resulting subsequent work.

I've glazed windows many times and it is never a fun chore. I've always used DAP brand glaze because it is usually what is available and what the average DIYer is familiar with. After watching many youtube videos trying to perfect my technique I realized it wasn't my technique...it was the product I was using. I hated the idea of spending so much money for glazing but with a massive 130 Victorian home with all 23 original and massive windows (seriously, I have 10 panes that 5' by almost 3' each!) I really needed to do something difficult. So the talking heads on the YT were mostly using Sarco. It arrived quickly and I got right to work on my first window. Let me tell you...this stuff was amazing! I got my beads down with one pass. The other stuff ends up sticking and pulling and leaving a not show good finish, and often times I would have to pull it out and redo and then smooth everything out with boiled linseed oil (which also delays drying time). With Sarco I didn't have to redo any of my glazing, I didn't have to tweak or smooth anything out, the glaze laid right down and made a beautiful finish. I will never go back to DAP again for glazing. Sarco IS worth the extra money in finish and in reducing frustration!!!

This is the best glazing putty to get the job done. More expensive, but worth it.

I used this Sarco glazing putty to fix two windows and make two more storm windows and I can say that it is much easier to work with than the DAP junk I bought at the local store. It is more the consistency of creamy peanut butter and after working it in my hands it is very easy to spread and shape. It came with a little oil on top of the putty in the can and so it was very fresh. I got good results for a rookie and it took a few days to set up but so far no cracking or issues. I would buy it again if I need to fix an old window.

The best glazing on the market! Co distant quality and professional results.

After reading several DIY articles online and despite the cost of this product (significantly greater than modern caulking options), I decided to get this traditional glazing putty to glaze old wooden framed storm windows that had been done with linseed glazing putty about 50 years ago. I am not a professional - just an ambitious DIY person. I did my first windows a year ago and this is what I found:Putty is very pliable - some batches stickier than others. I liked this because I am a novice, and it could be pulled and shaped again if I messed up.It is meant to be applied and then left to "skin" over before painting - this is time consuming for a project as it takes days to weeks for it to skin over.It has a strong linseed odor, which did not bother me but might some people.I like that it is still made in Chicago by (I believe) the original company that produced it.I glazed several windows a year ago, painted them, and hung them for the winter - Minnesota winter. The glaze held up great to the elements through autumn, winter, and spring - stored windows for the summer. I purchased more this autumn to finish the last few windows.One of the reasons that I decided to use this is because it is supposed to hold up to time. We will see. I can say that after 50 years, during which the old linseed putty had not been repainted, it was cracked in some areas. Still, for not being maintained, it was holding on pretty good. That was one of my big driving factors to use the traditional putty over modern alternatives. If I find myself with a glazing project again, I will use this product.One more note - I had some of this putty left over from a year ago. I had balled it up, wrapped it in wax paper, and stuck it back in the container hoping that I would be able to use it when I got to finishing the rest of the windows. After a year - stored at moderate temperatures inside - the putty was still fine. It was a little drier than new product but not enough to change its pliability.
