window installation question
Posted by: BernDog
Date: June 18, 2017 02:50PM
I'm installing a couple egress windows in my basement. The installation directions specify that I use liquid applied flashing as part of the installation process. I was having a hard time figuring out exactly what type of product they were referencing until I found this article: [www.greenbuildingadvisor.com]

This article lists about a dozen different products, but none of them are available locally. The article itself also states these products may be hard to find. Is there some other product that would be acceptable to be used as liquid flashing for window installation in a masonry wall that's easier to find? The instructions just throw "liquid applied flashing" out there like it's no big deal, but apparently it is.

I have a number of home centers to pick from in my area including Lowe's, Home Depot, and Menards. Nothing I see in their inventories seems quite the same as what's sounds like liquid flashing, but there are so many other products, my head is swimming. Any advice?

The question you need to ask is why do they prefer liquid applied flashing. Is it because it's "idiot proof"? I've installed many exterior doors and windows always using peel and stick flashing. No problems.

The instructions for a framed wall use standard flashing, and for masonry they give liquid applied. The little info I could find sounds pretty good, and, yes, idiot proof.

My included instructions are vague, but the PDF available online says Protecto Wrap LWM 200 or equivalent.

Yeah, I'd go with fool-proof; but as anyone knows, fools can be so ingenious...

This is sold as roof repair, but it's the same purpose – filling gaps with waterproof material, including around masonry chimneys and skylights.

Available as a paste in a bucket or in a smaller tube for a caulking gun.

Thanks! I've looked at that and a lot of similar sounding products. One vote for Henry Wet Patch.

Good article, thanks! That one, as well as the link I gave, list numerous products that aren't available locally and/or to the layman.

I just find it perplexing that the instructions for a window bought in a store recommend a product that's so much harder to buy.

HD here ( nor Lowes ) neither has the thin paint with a brush stuff but they do have (DAP or LOCTITE) polyurethane roof and flashing sealant in caulking gun tubes. It's thicker and gets troweled flat with a plastic spatula
STicks to just about everything but EDPM rubber, iirc.

I just had to purchase parts at Home Depot and shelves at Lowe's. Lowes had the shelves I wanted but plastic hangers, not the metal ones I preferred. So two stores for a closet shelve redo.

As for the other roofing stuff for the masonry. That would work from what I've read.

Thanks all. I'm going to wait a little longer to see if anyone else chimes in with any reasons I should or shouldn't use one of the already mentioned products. FWIW, in not super worried. I'll have covers over my window wells. The old ones I took out (with makeshift covers) had been there since 1936. We've been here for 14 years and we never had any moisture or flooding problems. They were crappy metal frames with single pane glass. I'm sure whatever I'd do, considering it'll also be covered, will perform at least as well.

Totally waterproof. 3M 5200 or Sikaflex, both polyurethanes. Use it underwater on boats.

5200 is some crazy good stuff. Sometimes used to glue a keel to a sailboat.

About all I know is that the polyurethane mess is great. That is some tough stuff.

Scanning marine sites for how 3M 5200 is used, I found this page that has a sealant application chart: [www.westmarine.com]

That would be a stretch. Keels are bolted on or encapsulated.

Check a local roofing supply or lumber yard and ask for a liquid applied flashing for an Air Barrier systems. Typically used on exterior walls
Sika, Wr meadows Vapro shield all have it as an accessory for their air Barrier system

You have to be real careful where you use that bonding adhesive. If you ever have to separate the bonded items you usually have to destroy one to save the other and then grind the 5200 off.
