ZIP SystemLiquid Flash | 10.3 oz. Cartridge | Weather-Resistant | Flashing Sealant (10.3oz Cartridge)

Zip system liquid flash is extremely easy to use and seals watertight as well as airtight. It may seem a little on the high side dollar wise, but it works and works for years on end at keeping the air and water out wherever you place it. Extremely well worth it for new contruction or high end remodels if you are truly trying to keep the air and water out of the home around windows, doors, and any other penetration. Do it right the first time so that you don't have to go back and do it again a few years down the road.

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.

It is doing the job that we bought it for.I don't know much about t but my husband says that it is working fantastically.

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.

I really like how versatile this product is! My first tube unfortunately leaked quite a bit out the back of the tube plunger, excellent adhesion is great, except for cleaning it off my new caulk gun. So far, the second tube I'm using hasn't been leaking out the back so hopefully that was a odd fluke.

Easy to use

Works great for flashing over-driven nails and screws, the edges of Zip tape, or flashing joints without using the tape at all. It really does work as good as advertised.Ordered a case from Amazon. Never showed up. Finally received a message saying it was damaged in shipment and not deliverable. Never received a replacement or a refund. Finally had to burn over an hour on the phone to get my refund. Worse than pulling teeth.

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