ZIP System Liquid Flashing - Fluid-Applied Sealant with STP Polymer - Professional-Grade - Weather Protection - Exterior Sealant for Hard-to-Flash Surfaces - 20 oz Sausage

Great stuff! Making new home air tight

Decided to re-side my garage with new 4 x 8 LP Smartside panels. Existing siding is also 4 x 8 plywood paneling in rough shape paint-wise but still pretty solid. There were a few spots where the old paneling was below grade and got moisture damaged. Basically the inch of siding that overhangs the slab. Not wanting to pull all the old paneling I decided to just go over it with new. I trimmed out the bad spots with a rotating tool and then used this to seal and flash the old paneling. Bought a sausage gun on Amazon as well as the angled tips. Amazed at how much easier sausage guns are to use compared to the traditional caulking guns. I watched a YouTube video of a guy using a similar product called Procoso R-Guard Fast Flash. I didn’t like that it was pink/red. I was going to buy them from Amazon and noticed this as a recommended product. I like that it’s black, especially since in my case the bottom of it will be visible on the slab that is exposed and above grade around my garage. I fixed the grade around the garage and then used light green 3m Rough masking tape about an inch below the old panel so I could pull it and get a straight line when I was done. Worked really well. This stuff will stick to about anything. I ran a bead on the underside lip of the panel, also on the very bottom face of the panel (about 1.5 inch), and also the exposed slab below the overhanging panel. Then used a chip brush to spread it just like the video I watched for the other product. Basically creating a painted on Z flashing. Again very happy with the result. I did this in Nebraska in June which was high 80s and 90s temps over two weekends and pretty humid. No issues with not sticking. I did sand the old panels with a power sander where this stuff was going so I could remove all the peeling paint and have a good surface for it to adhere to. Stuff is very sticky. Use nitrile gloves, lots of them. And wear old crappy clothes. I did one side of the garage at a time. Stuff starts to skin over within an hour, it’s still very tacky, and you can keep painting on more if you’d like. Pulled the tape at the bottom once I finishing painting a full side of the garage and it had started to skin. Tape comes off no issue and flash falls back into place with a fairly clean line. Basically feels like a tacky rubber after it dries. I’m happy to find a solution for flashing the bottom sill in my unique situation on an old garage where the mud sill is sitting right on the slab. It’s sealing all the cracks from pests, making the sill more air tight, and water proofing all at the same time. The uneven parts I had where I cut away the rotted parts of the plywood were no issue to seal with this as it sticks to anything you paint it on. The only question unanswered for me at this point is how long will it last? Tube says 30 years but I never understand how a product just coming to market can know that? I did try using the plastic spreader on one side as that is how Zip shows to put it on. I bought cheap yellow automotive ones from Amazon. But found in my case with the overhang of the panel, it was easier to use a 1inch chip brush. The plastic spreaders may be great for doing mud sill boards before installing on new construction but again in my unique application they weren’t the best. Plan to run 1x4 PVC Water boards on the bottom, over this liquid flash to make my new panels sit 6 inches above grade like they are supposed to. Hope is the bottom exterior edge won’t rot out on me by using this and PVC boards. Time will tell. I ordered from the Huber 3rd party reseller and each tube came inside a sealed plastic bag. Might be worth ordering your tubes without other products that can poke holes in the tubes just in case. Mine were all new tubes that wasn’t expired. My garage is 22’ x 18’ and I ordered 11 tubes not knowing how much I’d end up using. I probably could have bought 8 and been fine for what I did.

This stuff is awesome. No more origami on window installs. Also works great as a bug sealer for that lowest coarse of sheathing and the concrete block. Only downside is the clean up can be messy. Get a quality sausage gun with the correct tip for your desired application.

I am using Zip liquid flashing in conjunction with Zip system panels and tape flashing on my new tight home build. This fluid applied flashing has been great for flashing my window pans and the edges of zip sheathing at window or door openings and sealing the footer / mudsill to the foundation. Purchasing it in the sussage tube is a big time saver and reduces waste. I've found the sussage tube to also be cheaper here on Amazon over plastic tubes or sussage tubes elsewhere online. I would definitely reccomended warming the sussage tubes to 60 or 65 degrees before applying. You will find that it applies easier, smoother and further when warmed. I also found a notched "Henry" brand trowle / spreader that closely matched the required minimum application thickness. This trowle was a game changer in the application process. If you are looking for a fluid applied exterior flashing product, I would certainly not hesitate in using the Zip Liquid Flashing. My house is still a "construction war zone" and the cured product is holding up to the ongoing work, without concern for spot checks or touch up. Bonus, can be applied to wet surfaces and the VOC or chemical smell is rather light plus aromatic.

Great product but how to apply this stuff without making a total mess is something their engineers should figure out and include an applicator!

This is a fantastic product. By far the easiest way to flash a window or door opening and get a 100% air and water tight seal. Also very helpful for sealing any difficult penetrations through your wall sheathing. Takes the place of Huber Zip flashing tape. Make sure to have a plastic bondo spreader or similar object, gloves, and obviously a sausage tube caulk gun and tips for it. Also for reference your average window will take 2-3 tubes to flash the entire thing. I've found a more efficient way is to flash the sill with this and 12in up each jamb then switch to the Zip tape.

Great product but messy. Not a fan of using it in window and door openings anymore. Too time-consuming and messy Plus you have the pretty much wait for it to dry to set a window. Use zip tape for that. I like this product for sealing the sheathing to like a concrete slab. Nail penetrations as well.

We used it for sealing zip boards at the bottom of garage and also at nails holes on sides and middle. I didn't use the whole package and sealed it in ziplock bag and was still soft after 2 weeks. Just the opening at top of tube and was hard but easy to remove. I like the tape but so much easier to use on nail holes in middle as easy to spread.

Good product, but it's very expensive almost not payable for big project.
