Prosoco R-Guard Waterproofing and house wrap

Unwrapping the Prosoco R-Guard System: Efficiency, Durability, and Expert Insights

Foreword by Ian Thompson, Editor

The video is about the Prosoco R-Guard system, a fluid applied waterproofing and air barrier for houses. It’s a system that provides comprehensive coverage for the entire exterior of a house, replacing traditional house wraps. The system consists of a roll-on version known as CAT5, a joint and seam filler, and a red fluid called FastFlash.

The Prosoco R-Guard system is highly rated for its efficiency, durability, and ease of application. It adheres seamlessly to itself, eliminating concerns about the direction of the house wrap or the order of application. Once applied, it forms a thick rubberized coating that is completely waterproof and air-proof.

In a conversation with a builder named John Young, the builder expresses his preference for the Prosoco R-Guard system over traditional house wraps. He appreciates the system’s ability to seal off everything, its resilience to damage, and the ease with which it can be touched up. He also finds the installation method easy to teach to other builders. He even trained his painter to apply the Prosoco R-Guard system. He opted for the rollable version of the system to ensure thorough coverage. He also used a thicker OSB for sheathing, which offered better anchoring and improved the strength of the house.

When it comes to dealing with penetrations that occur after the application of the R-Guard system, John uses spray foam to fill in any larger gaps. He then applies the joint and seam filler to ensure a watertight seal. He also uses the FastFlash to seal the back of the copper flashing and the top of the ICF, before applying the copper flashing and the R-Guard coating.

Overall, the Prosoco R-Guard system is seen as an innovative and effective alternative to traditional house wraps. It’s easy to apply, efficient, and offers superior waterproofing and air-proofing capabilities.

Prosoco R-Guard Waterproofing and house wrap

That you could roll on your waterproofing and your air barrier for a house for a perfect coverage on the entire outside of the house. That’s what we’re talking about today. We’re going to be reviewing the Prosoco R-Guard system.

I’m visiting a builder who previously has been using house wrap on other projects and is doing the R-Guard system now. If you’re not familiar with this, this is a fluid applied waterproofing. This was dried already.

We’re actually filling in right here and it kind of feels like a big bed liner or a rubberized coating for the building. This is vapor permeable so you can actually dry through it, but it’s totally waterproof and totally air-proof as well.

Now he’s rolling on right here out of this bucket the roll-on version. This is CAT5, but you also see there the pink that’s on there at the seams where the plywood comes together, or rather the OSB comes together. That’s their joint and seam filler. And around the house you’re going to see some red fluid applied as well. That’s called FastFlash. This is all made by Prosco and it’s all a system that works together.

What I like about it is because it’s a fluid applied, it sticks to itself. We’re not worried about which way is that house wrap going, are we shingling things? It really doesn’t matter what order you do things with a few minor exceptions. But when we’re all done, we’ve got this really thick rubberized kind of coating on the outside of the house that’s totally water and totally air-proof.

All right guys, I’m here with John Young with John Young Construction. We’re in Dallas, Texas. John, I understand you have done a lot of house wraps in the past. And in fact, you were talking earlier and telling me that you might use a house wrap on the project, but then before the masons come like this, this house full rock on the outside, you put another layer of house wrap. What do you think about this Prosoco R-Guard system compared to like a standard house wrap?

“I really, really like the the way it works, the way it goes on, the way it seals everything off. I like that it can be damaged and easily touched up, where the house wrap definitely works okay like that. But also, I like the way I can put anchors in it, it seals off as it screws in.”

Yeah, it’s a rubberized and uh it feels like it has a gasketing effect right? If you put a brick tie on there and you and you screwed or nailed that brick tie on, kind of feels like a rubberized kind of coating right, that gaskets onto that nail or screw?

“Definitely, and that’s been what’s a house wrap it’s been an issue where it had some seeping uh around nails where anchors go in it. And I really like the idea of everything sealing off and rubberized. And as I work on it, it’s easy to touch up, it’s easy to add to it or whatever if there’s something missed. And I really seem to like the product a lot.”

That’s nice. Now John, you uh are not using your in-house guys to do this. You’re like me, you’ve got a couple guys that work direct and do a little bit of everything. Uh, what made you decide to use an outside crew compared to your in-house guys? “Just for the manpower, they, what we did the overall structure, they had 10 guys they could throw on it and I don’t have that many guys.”

That makes sense. So you actually used your painter and trained him on this, right? “Right, and did you just get out there and uh and get going with him or did you have a Prosco guy come help you?” “What a Prosco guy, they sent a rep out um the shoulders kind of getting a little quick lesson then they were very good about it.”

So that’s awesome. And it’s pretty straightforward, isn’t it? It’s not that, it doesn’t seem like it’s that difficult. “It’s very simple, very easy to teach to almost anybody.” And did you roll this house or did you spray the house because they make a sprayable and a rollable version? “We actually, I got the rollable version because I want to make sure it’s worked in all the areas, and so I made them, made them roll it on.”

Yeah, sounds and you’re used uh it looks to me like a thicker OSB than it’s kind of normal on this house. Would you end up using for sheathing here? “I use a three-quarter TNG shooting on it just uh gives me a good anchoring uh makes the house actually stronger also.” Yeah so it’s all nailed on very well.

Um, I get easy to put anchors anywhere you want to work and you’ve got a full masonry exterior. So having that three-quarter like you mentioned means that now the masons don’t necessarily have to hit studs. You’re still going to get that value uh by nailing or screwing into that three-quarter inch thickness. “Nailing into that thickness? Oh, I’m gonna have them screw it on so I’ll have to do the first red screw and it’ll really, really hold.”

Yeah, I like that. Uh last question for you, I noticed that your penetrations happened after. It looked like maybe for instance, these plumbing penetrations here happened after. Walk me through the process of waterproofing those uh if let’s say the plumber comes after you do the R-Guard system?

“Right, so we just, we foam around the penetration for any larger gaps and then we cut it back. And then then apply the either the FastFlash or the uh I’m sorry I forgot that it’s called joint and seam filler, joint and seam filler, yeah, the pink stuff, the pink stuff.

Yeah, so then we apply that over the top of it so that foam, that spray foam that can foam kind of fills in the gaps so you’ve got something to stick to. And then that joint and seam filler which has a fibrous material in it is able to span pretty good gaps. And my understanding is it will, it will uh accommodate some movement as well.”

“Definitely, definitely. And that’s that’s really nice because the pipes and so forth as they working on the house, things will get moved a little bit. It’s good to have some flexibility to it.”

John, last question for you, it appears that you’ve got a stone ledge out front and an ICF foundation maybe. How are you waterproofing that joint where your OSB sheathing comes down to that brick ledge?

“So that’s why we’ll use the FastFlash. We’ll seal the back of our copper flashing, it will also seal to the concrete at the top of the ICF. And then apply the copper flashing and then we’ll take the R-Guard uh the FastFlash over top of the scene and then the Prosoco R-Guard.”

That’s really nice. So basically that copper is bedded into some FastFlash, right? And then you’ll also where that copper stops, you’ll nail that in with some copper nails and then put a joint and seam filler right at that top so that any water coming down from the wall above will hit that copper flash and then get kick forward? “Correct.”

Man, you’re a nail in details, John. I really appreciate you letting me come out and see your job site, my friend. Thank you.

Guys, I’ll put a link to John’s website. He is under the radar here in Dallas. He’s got plenty of work. He’s definitely a word of mouth builder. Uh, but been building here for 40 years, a really smart builder. And it’s fun to see him make a change to a newer technology and and have a good success story with it.
