RV Sealant - Non-Sag vs Self-Leveling

The kind of sealant you apply to your RV is important. To determine the type of sealant you need for your application, you will want to consider what it is you are sealing and where it is on your RV.

Self-leveling sealant is designed to level out as you apply it. The thick liquid slowly flows into a level position as gravity takes effect. This is particularly useful when sealing flat surfaces, like around a roof vent, AC, or skylight. As you apply the sealant, gravity will cause it to settle into an even line, giving you a clean, low-profile look.

Non-sag sealant is designed to retain its shape as you apply it. The consistency of the liquid is thick but malleable enough to be easily applied without causing sagging or slumping. This is useful when sealing vertical surfaces, such as the edges of a wall, window, or vent. As you apply the sealant, it will harden just enough to keep the liquid from drooping, giving you a clean, even look.

Video Transcript for LaSalle Bristol XTRM Universal Self-Leveling Sealant Review

Hey, everyone. Shane here with And today I'm going to walk through how to reseal the top of your camper RV.Every five to seven years, you need to look at the seal that's going around any of your components on top of your roof and along your sides. If any of it is cracking or coming up like this, it needs to be replaced. The reason we want to replace it is because anything that is going down the roof has something that is going down inside of the roof or inside the ceiling. So if we don't have anything sealing the edge, what can happen is water can get underneath and it can cause damage inside your roof.

You may not see it for many years down the road until you start seeing it on your ceiling. By that time, not only all the insulation is soaked on the inside, but also the ceiling inside is going to be wet and you're going to have to replace a lot of extra stuff that you don't otherwise want to do. It's going to costs you a lot of extra money.So do some routine maintenance every five to seven years. Look at it. If it's peeling up like this, or if it's cracked like that one over there, it can potentially cause water damage.

We're going to be using LaSalle Bristol's self-leveling sealant, and that's going to be for any horizontal surface. So anything up on top of the roof. And then for anything that's vertical that may be on the side, you're going to use the non-sag sealant.Now these are going to come in beige or white. They're going to be universal sealant. So they're going to work on many different types of membranes, but not only that, they're also going to work with brass, steel, glass, PVC, EPDM, TPO and TPV.

So they're going to adhere to a lot of different materials. They're also going to hold up in a lot of different weather conditions, you aren't going to have to worry about in the coldest temperature or the hottest temperature, the material breaking down and causing a leak. It's designed to hold up against all those weather conditions. When installing this, one, it's a good idea to clean your roof, get any dirt or anything like that off so that this adheres to the roof membrane as good as possible. Also when putting it on, after you get done, you want to make sure you let it dry for 24 to 48 hours.

So after that 24 to 48 hours or before that 24 to 48 hours is up, you want to make sure it doesn't get wet. You want to make sure you don't travel with your camper or your RV.Before we install this, we need to make sure we remove any of the old stuff and clean up the roof so that when we put this on, we get a good, it adheres well to the top of the roof or the membrane. This is coming off pretty easy. And again, look right there, that is potentially open so water can get underneath there and cause damage that we really don't want. So this is actually coming off a lot easier and I've ever seen any other ones come off.If it's not doing this and where it's cracked, you're going to take a plastic putty knife. You want to make sure you don't damage the membrane and we're going to try and get it as clean as possible. We want to remove the old stuff as I mentioned before. Once we get it all cleaned up, we are going to be using our self-leveling sealant. I'm going to be using beige so it matches the roof and the camper. We're just going to lay down a new bead. As you can see, I'm not going right on that edge just yet going up above it. What this stuff is going to do there, as it sits for a little bit, it's going to start flattening out.I'm going to put a bead up here first and then I'll come back and put one down below, right along the edge, where this is going through the roof membrane. And then the two are going to form together and then flatten out. So it gives it a good cover. Once you get one done, you're going to move over to the next one and repeat the process. Once you get it laid on, you want to make sure you leave it on for 24 to 48 hours without any water hitting it or without going down the road and wind blowing on it. Now there's a couple of ways you can do these. The cracks there, if you wanted to go over the top of it, you can. I, myself, don't like that because this is cracking under here only you're only covering the crack. Well, the new stuff that you're putting on, with it not adhering to the actual piece that you're putting it on in the membrane, it could potentially come off of this, may not adhere to it well, and also it could fail real soon or fail a lot sooner. So you have a crack there and the new stuff you put on, you're just covering up an old crack. Doesn't adhere to it. It cracks. You're having the same problem. You're going to have to rip it all off anyway.So my opinion, go ahead and just take off as much as you can of the old stuff, clean it up, put the new stuff on so you get a good solid, so it adheres well to both surfaces.Once you've got everything covered, you're ready to go for. That's it for a look at an installation on a LaSalle Bristol's self-leveling and non-sag sealants.
