If you are remodeling and can’t access the outside sill follow this interior video of mine: kzbin.info/www/bejne/gnrZgZ-XYpVqnNE

[@Hedgehodge-]

Lol so the time has come, I'm at a loss even with watching lots of these videos, how does one approach this (my house - photos.app.goo.gl/84dZCuFJKbtd24wn7 ) I'm open to viewers suggestions too. I'm unable to access the sill from inside (about to tear open inside the house and look but...) Even after... I will remove both layers of siding (even some behind that concrete) and then find the extent of termites but even if I manage to replace that sill, how do I go forward making sure that's sealed off correctly? Put the 7/16 on the old clapboard and 0.5" above it and just liquid flash bottom foot on both sides of OSB and sill board on the bottom and side towards concrete with it sitting on two sill gaskets then stick it down there and then stick some mineral wool in there? Or air dam, big gap, or leave it open (the remaining gap to concrete? Then a flashing that goes near top of concrete on sheathing that dumps to past that concrete then 2" mineral wool and rain screen with covavent and siding?

[@allanlindsay9414]

Last summer after watching your channel for some time, I went around the entire house and pulled off the bottom two rows of vinyl siding and start strip, taped up the house wrap, and applied Prosoco R guard from sausage tubes around the whole house foundation to sill plate joint. Tooled it off, waited a day for it to set, and put everything back together. Wow. No more bugs. Drafts reduced considerably. It was a fair bit of work to do it after the fact, but it was totally worth it.

Make sure to do the top plates and all the penetrations and the joints of your sheathing, too, and use a good quality house wrap. You don't want any water or vapor to penitrate and not be able to drain out the bottom. I'm doing this with my house as well.

Yeah, im going to put the time in once i replace some parts of my 97 year old house.

Hi Matt, I’m a firm believer in building sciences and I’ve been well educated from you so thank you buddy! no I am not in the construction industry with that said I did a remodel to a house I owned back in 2005 before these products were even invented! 3 years ago I purchase a brick house in Rural Utah built in 1909 with an addition added 55 to 70 years ago, that’s mentioned in my below post. I now know more about building sciences then 99% of all homeowners with the exception of homeowners or builders watching your Awesome videos or attending the IBS. (International builders show)

[@wjthehomebuilder]

This is great for slab on grade. But what about when there's a floor joist system? Seems like bugs can come in from the crawl space side.

[@KPHVAC]

Seal up the crawl space and/or the flooring at every floor joist, corner, crack, and gap. All you can do is seal everything up as much as possible. It certainly would be time consuming.

[@Nonsense62365]

Great idea! I have an addition on the back of my brick house built in 1909. the addition was built between the 1950s and 1960s. It has 7/16” fiber board over the 2 x 4 framing with a rotted paper barrier that’s in really bad condition from getting wet Over the last 60 - 70 years. With Cedar Siding nailed on top. bugs laid their eggs underneath the bottom 1” of the cedar siding. I’m removing all of the fiber board installing 7/16 x 4 x 8 Zip Sheating, with 1” x 4x8 polyiso Atlas Energy shield, Also replacing the cracked cedar siding with LP siding. Using button caps to attach the poly iso-board to the Zip Sheating. Buying 1x2x 8 ft common wood used as Batons and installing CoraVent on the bottom of the batons. Matt has a video about this. The 3/4” spacing created by nailing The siding on top of the Batons allow a air separation on top of your zip sheeting or your polyiso insulation. whatever siding you buy the siding has 3/4 x 16 on center space x 8 Ft to breathe from the bottom up to the top! Using this methodology you won’t have the issue that I have because the people who installed the cedar siding didn’t know these building techniques!

Rothoblaas has tons of solutions for wood buildings, for that specific area included, nice and snug, airtight and waterproof. Check that out, maybe pay them a visit in Italy, they're just great when it comes to wood. Also you can have a look on Aerosana Visconn Fibre, liquid vapour barrier.

I swear you know I'm fixing termite damage on my sill/rim on an old house and stripping two layers of siding and putting zip system up on 1" tongue planking with wool.... Was wondering what to use after it's gapped 0.5" off ground , before the coravent goes up

[@MichaelM-to4sg]

I get sticking w/Huber products given the Zip sheathing and that I believe you’re a paid spokesperson for Huber. We however have found Siga Fentrim tape is less expensive, both in material costs and vastly less labor intensive than the Zip liquid flash. Fentrim tape comes in multiple widths, we use Fentrim 150 & 230 depending upon application, and sticks far better to the concrete without needing a primer. Since our concrete foundations get a liquid or peel & stick membrane water/air barrier, the Fentrim has a felt like texture that Polywall liquid membrane adheres to extremely well. When using bituthene, such as Delta-Thene, the Fentrim adheres to the membrane w/o chemically damaging it. Yes, it adheres very well to Zip sheathing, since we commonly use Zip R-6 on majority of our homes. I would recommend you try Fentrim tape on your next project, your crew will thank you 😉

[@pcatful]

And water coming down the Zip membrane: Looks like a flush layout, concrete to the sheathing, so why wouldn't water on the Zip sheathing just go in over the top of the concrete? glad you did this.

[@Hedgehodge-]

Are you asking why you can't just touch the zip sheathing to the concrete and then seal? If so it's because the osb behind the waterproof membrane would wick water from the concrete below. With the gap it's not possible and with the sealant you won't even have condensation chances anymore that could wick up and mushroom the backside of the OSB

[@contemplation9402]

Could the cavity be filled in with expanding foam like you did around the spigot before going over the joint with the liquid flashing? The expansion of the foam could be controlled with tape or a temporary form. It might be faster than tooling the liquid flashing into the recess.

[@enkrypt3d]

the bottom plate is sitting on 1/4" foam to give it a thermal break... so there is somewhat of a "backing" there already

[@contemplation9402]

​@@enkrypt3d Yes. After the foam expands and cures, remove the tape/form and, in theory, the surface should be smooth and flat - ready for liquid flashing. I also wonder if it would work to use only expanding foam and skip the liquid flashing. I did it Matt's way (tooling into the joint) which took a very long time and used a lot of product; 20+ sausage packs, on 300ft of wall.

[@NealD]

Too bad so many Austin area builders just don’t care about things like this! Check out these massive subdivisions going up - they screw up the most basic things like drywall in the shower and then glue tiles directly to it. No proper support behind, no water barrier at all.

Maybe even building access areas every installer wish was there but never is (make sill plates always visible from inside or blah blah). Man, I wish I thought about adding insulation on top of my roof before it was done, what a stupid move on my part. I also think you should have RJ45 plugs in each room on opposite sides with 2 cat6 ran to each spot and never daisy-chained that go to a central location in the utility room. Can be used to power cameras outside too if ran outside.

[@macthemec]

Would a fiberglass tape and epoxy resin work as well? The mess, bond, and seal would be about the same if not better. The cost and number of tubes needed to fill a gap on most projects would be enough for me to seek alternatives. I often think the same about these zip systems. Would a lizard skin on regular OSB work or a composite and epoxy tape over the zip sheathing joints and nail holes?

[@MerkDolf]

I wonder why we don't put a sheet of copper in the concrete foundation so when we put that pice of wood on top it pierces into the wood to make a complete wall, then fill in the gaps with some type of awesome liquid epoxy (Calking) to make it really air (water) tight so then no bugs would walk through?

@@9mmkahr I hear you. We have done a few buildings the way I mention, maybe our foundation guys have spoiled us.

@@2mustange The moisture you worry about with sheathing is generally condensation, not bulk water from the outside. So when you hear people say that a sheathing is breathable, they’re referring to water vapor coming through. (Generally that water vapor is coming from the inside depending on climate)

Matt, I want to do this but the OSB extends about an inch from the foundation. How do I apply it?

[@xartpant]

Why would you put that extra bead above and under the gap?

[@ehsanmanoushan9979]

We have a new house and the siding boards are installed and I do not have access to the joint area. How can I do this?

[@vanoknt]

im my humble opinion, aftrer working for more then 10 year in comercial constructions and using all kind of air bariers, the use of duct tape near fouindation is a vaste of money! this joint will get covered! all you have to make sure is that joint is sealed properly!. the other grate product which is more expencie is foil faiced tape! that thing will seal your fraim to concrete fenamenoly, you just have to make sure their is no dust or moist on the concrete or frame.

[@Matt-dc8lp]

Very cool but quite a pricey fix. That zip liquid flash is expensive stuff.

[@runiniscrazy]

I don't understand the tape on the concrete i was going to comment the same on an older video using prusco. Matt says we don't want the material exposed to sun light, what happens if it is? Will it ruin the seal for bugs or is it purely aestheticsbif you are covering it does it matter?

[@wadebarnett2542]

Matt, did you do that to the interior or exterior of the wall?

[@stephencali8902]

is this compatible with Dupomt Thermax exterior foam boards?

[@AdamCarbone1]

Couldn't you also use some Siga Fentrim tape?

[@thinkoutsidethecontainer]

when will build science discover a way to make homes 100% bug proof?

[@goldblueberries326]

The tape is not necessary.... it willbe covered by the siding

[@Goodwithwood69]

A mesh tape \ scrim would give it more longevity?

[@Goodwithwood69]

Not sure how to do that?

[@44ryang90]

What if I have brick in an existing house? What is the rec for that?

[@buildshow]

If you take off the brick you can do this. Otherwise follow my advice here: kzbin.info/www/bejne/gnrZgZ-XYpVqnNE

[@markb1764]

you aint gonna get much mileage out of the tube doing it like that

[@johnbalogna803]

wouldn't caulk or silicone do the same thing???

[@wayneguy6043]

Good luck getting contractors to go above and beyond for a reasonable price or at all…….

[@Alogan227]

Is it bad to Tyvek a Zip wall? I'm not doing this, just saw it in a custom home.

[@Alogan227]

I decided to reply to the above name and I now realize that it is an account that isn't associated to @Matt Risinger . I didn't really think about what the above comment was, I just responded. The above account will ask you generic questions about how long and what knowledge you've gotten from him and then they will try to sell you a Bitcoin Trading account.

[@AD-cy7wx]

That looks… expensive. I bet some OSI siding caulk would do the same thing at half the price… and that stuff sticks to everything also. ;)

[@williambryan5188]

Definitely ALWAYS “push the tip in” just like Matt says. And……that’s what she said.

[@consumersgasman8376]

I would have thought the bead of sealant alone would have done the job, dont see the point of the taping and smearing, seems like total overkill.

[@bowater1967]

Money grab for zip. Just use con ad in conjunction with sill seal. If you’re paranoid, use silicone and do the same method he’s showing $4 per tube vs. $40 per tube. Btw, I love other zip products. In fact I just picked up a couple thousand dollars of the zip liquid flash for the first time, as far as Im concerned this product is nothing more than glorified silicone. Just my humble opinion…

[@RichTCS]

Is it just me or does that concrete footer look pretty popcorny? Doesn’t seem like the concrete was vibrated very well right in this vicinity….
