Sarco Type M Glazing Putty (Quart)

Q: Outside use or only inside facing glaze? Says Type m is for inside shop only.

Hello! When we say "inside shop" we are referring to the application of the product. You don't want to apply the putty and leave it outside before painting. Type M is for exterior or interior side facing windows. I hope this answered your question.

Q: What is the best way to keep it from hardening between uses? I tried plastic wrap on the surface, but of course there were small gaps around the edge

Plastic wrap is good. You can also add a layer of water on top of the plastic wrap to press the edges more tightly against the sides of the container. Of course, store the container upright on a shelf. Just pour the water off before removing the plastic wrap for your next use.

Q: Can I use this outside in the fall? I don't want to take the entire window off. I have storm windows, so it will be protected against rain.

It is only recommended for glazing in a shop and is only for wood sash (not for steel windows). 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. All in all, this is my favorite putty! <------ That's per Sarco. Sarco needs at least 3-4 days to skin over, and I'd be leery of using it if the temperature gets below 50 degrees.

Q: Will this work with water based paint or lacquer?

Once it dries you can use water based paint over the top of it. I used a basic water based acrylic house paint over the top of it with no issues. Takes many days to dry/harden, but I loved working with this so have used often.
