I decided to use a foam sealant instead of the caulking when weatherstripping our storm windows. I have worked with the polyurethane foam stuff that expands and stays on your hands for two weeks (Great Stuff.) It is so very messy and not for this use as it is permanent. I tried a latex foam product a few years ago on the storm windows on the sleeping porch I liked it very much. From season to season you can just take a scrubby or a razor blade (carefully) and remove it and reapply when you put them back in. It’s white and it’s like whipped cream and washes off your hands with soap and water when your done. It takes a bit of practice to make it look neat. Paper towels, a bucket of water and barely damp sponge works well for making it look neat. You won’t be able to open the window once done or you’ll wreck the seal. But if you have to open it, it is easy to scrape off the old and add new foam.
The down side is this product is the white “fluff” when you go to remove the windows in the spring. It will brush off with your hand and then you can get the remainder off with water and a scrubby. Have a vacuum handy or you’ll have white fluff like a trail down the hall through the living room and out to the garage. This product is Dap foam latex sealant. I went to Lowes and they didn’t carry it. The worker said they stopped carrying it a year or two ago. Why? Anyway, I went to Home Depot and they had it.
The other “stuff” I’ve used that works pretty well for temporary use for the winter around windows that you don’t use in the winter is the 1/4 inch rope pliable caulking you press around the window. Anyone can use this stuff. You just unpeal a strand of the rope caulk and line it up with the edge of the window and press in down. We don’t use the window in our 1/2 bath and the thin rope is pressed around the whole window for a few years now. You can just peel it off when you want. It looks nice and neat when done properly and it was inexpensive to do, under $10 for 90 feet. I’ve seen it in gray and in brown.
I worked on the patio door with the Dap latex foam sealant yesterday and today I’m going to paint a little around the door’s trim that needs touchup. I’ll also work on the storm windows (squirting in the foam sealant) on our front porch. I think they may need a little touch up of black paint, too. The basement windows look pretty well sealed up still. Hopefully I’ll get a lot done today because the forecast is for rain and colder temps the next several days.
