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.

The box arrived with both tubes of sealant rolling around loosely inside. The ends of the cardboard tubes are compressed in, one of the long application tubes is bent way over, and the other tube has sealant leaking out. I hope I can use the tubes of sealant if they are not dried out or the tubes holds up well enough to get the material out without a blowout. I have had 100% great products and service with etrailer but this time I am a bit disappointed in the packing of the product.

I will have our Customer Service team reach out to you.

I used this when replacing a vent fan in my RV. I ran out before making it around the fan so I ran to the local RV store and picked up a competing product (Dicor). When applied side-by-side it became very clear that this product is far inferior to the more popular product made by Dicor. The LaSalle Bristol XTRM went on just fine, but didn’t really spread and level out the way it should so it left a few gaps and left me questioning if it made a good seal. You can see in the photos I attached that it somewhat kept its shape as opposed to spreading out like it should. Spend a few dollars more and get the superior product. Weather was perfect at about 75 degrees so that wasn’t a factor.




by:

Fast service - received items in 3 days - thank you e-trailer




by:

This was thicker and more difficult to apply than I had anticipated. That said, I do think it worked ok to caulk around the refrigerator vent on an old camper trailer I have. It was an unusually cold day when I applied it so that may have contributed to my difficulties.




by:

Worked as advertised! Used it to install vent covers where I had to cut away the existing sealant.




by:

This stuff goes on thick and works wonders!! Must have for anyone with a RV or Travel Trailer




by:

Service was fantastic. Amy walked me through a change to my order and saved me having to place a second order, saved me extra shipping charges and was able to expedite the whole order. It was so great to have a real person to talk to and understand. Thank you Amy.




by:

Great product. Thanks Bob and your crew for the install of this product and the video you made. Have not had any problems with leaks or it coming loose.


Comments
Excellent product. No leaks. I would recommend this product.

There were. Some parts missing from the original order, but it was resolved with a couple of phone calls.




by:

Replaced a vent and moved a vent. The sealent holds and levels nicely, there are no water dams. The water flows away. Would have pictures but cover and snow.




by:

All around great company to order from!




by:

Easy to apply and spreads evenly




by:

Fast shipping and it worked great.




by:

Everything went perfect with my order .thank you very much .




by:

Didn’t quite self level as anticipated. Went on well. Time will tell how good it holds.




by:

just received it have not used it yet but excellent job of getting it to me.




by:

Great product. I used this to seal a new vent installation and it works perfectly. It is "self leveling" so expect it to spread out after you run a bead of it. I bought some extra tubes and I'm glad I did. When I installed the vent, I found the seal around our skylight to be cracked. Before I applied the product, I used a good cleaner and rag to clean the area to get a good seal. I'll use this again in the future.




by:

Worked great on sealing roof top vent, very pleased




by:

Very easy to work with. One of the best customer service out there.




by:

package came on time as promised. All items included. Great service from Justin.




by:

I have no idea why this is classified as self leveling. It didn't even try to.




by:

Great product! Does what it says it will do. Warm it up if your in a cold climate before use




by:

This caulking is the best leak stopping, fix it, gooey stuff out there. I've tried alot of them and this one is the best by far. I've used it mainly on roof seams and it works flawlessly. A must have. God bless.




by:

Great product. Still well within expiration date. Fast shipping.
I always have good dealings with etrailer. Great company. Thanks.

  • What Is the Dry Time of the LaSalle Bristol XTRM Universal Self-Leveling Sealant
    I spoke with LaSalle Bristol and they informed me that the LaSalle Bristol XTRM Universal Self-Leveling Sealant part # 34427034145-1 has a dry time of around 1 hour.

  • Using XTRM Universal Sealant to Replace Existing Original XTRM Caulk on Roof
    I believe you are referring to the XTRM Universal Sealant # 34427034145-1. If so, it can absolutely be used in place of the original XTRM 100 that was on your roof. This will work just as well as the original sealant and its weather-resistant formula will keep it flexible and in good condition for many years. As far as removing the old caulk/sealant you should be able to get most of it up with a good ol'e fashioned putty knife. As for the stubborn sections that won't budge a really effective...

    The LaSalle Bristol XTRM Self-leveling Sealant part # 34427034145-1 is very comparable to the Dicor 501LSW self leveling lap sealant. I can't say exactly what the formula is for Dicor but I can tell you that LaSalle Sealant is a silicone sealant used in numerous applications including the installation of RV roof accessories and we have great reviews from customers. It works well on Fiberglass and adheres to aluminum, brass, steel, glass, concrete, wood, and PVC. It also adheres to EPDM...

  • Should Lasalle Bristol XTRM Leveling Sealant Go On Before or After Heng's Rubber Sealant
    You'd want to do the Heng's rubber coating on the roof first as needed and then use the LaSalle Bristol XTRM Universal Self-Leveling Sealant # 34427034145-1 when re-installing the vents. You'd want to follow the curing instructions on the Heng's before using the XTRM.

  • Should You Remove Old Sealant Or Can You Add More On Top Of It
    It's always best to remove the old sealant first and then clean the area with soap and water to ensure a secure grip for the LaSalle Bristol XTRM Universal Self-Leveling Sealant # 34427034145-1. The old sealant could deteriorate and fall off taking the new sealant with it.

  • What Brand of Sealant Is Recommended For Filling Holes After Drilling in RV Roof
    The LaSalle Bristol XTRM Universal Self-Leveling Sealant part # 34427034145-1 is what we use whenever we have to drill holes into a trailer and seal them after. It can be used for pretty much anything from roof vents to just general repair. It works very well to keep out water and is really a must to have on hand for trailer owner's.

  • Will the TremPro 644 Silicone Sealant Work with PVC Applications?
    I have a solution for you. Even though the TremPro 644 Silicone Sealant # 0160297 is rated to use for plumbing applications, Fastenal could not confirm whether it could be used specifically on PVC. However, for a sealant that will definitely work with PVC, I recommend the LaSalle Bristol XTRM Universal Self-Leveling Sealant # 34427034145-1.

  • When is Non-Sagging Universal Roof Sealant Preferred Over Self-Leveling
    You'd want to use the non-sag sealant part # 344270341437-1 on vertical applications where you wouldn't want the sealant to drip or run. The # 34427034145-1 is better for horizontal applications as it's self-leveling, but it would run or drip on a vertical application.

  • Ratings For LaSalle Bristol XTRM Universal Non-Sag Sealant
    This is exactly the type product to use for sealing a roof seam on an RV, it is designed to seal the roof membrane edges and vertical surfaces. I suggest the # 34427034145-1 for a self-leveling option with skylights, vents, and other horizontal surfaces of your RV. The manufacturer of LaSalle Bristol XTRM Universal Non-Sag Sealant for RVs, # 344270341437-1 does not list a UV rating only that it is water resistant with a shelf life of 18 months.

    I do have an option for you but there is not an upgrade kit for a Fan-Tastic Vent E-Z Breeze Model 600 Vent Fan. Therefore, you will need to replace this for which I recommend using the Fan-Tastic Vent Model 2250 Roof Vent Fan part # FV802250 as it has a variable-speed motor, reversible fan blades, and a thermostat for automatic operation. Unfortunately, you will need to use the new garnish ring but this is very easy to replace. The LaSalle Bristol XTRM Universal Self-Leveling Sealant part...

  • Why Would Trailer Roof Vent Leak Water
    If your Fan-Tastic Roof Vent is leaking it's going to be a sealant issue between the vent assembly and the roof of the trailer. So you'd need to have the base of the vent resealed to the roof with sealant like the part # 34427034145-1 and that will take care of the leaking issue. Where is the red blinking light exactly? Does the vent still seem to work like normal?

    Yes, there is no issues mounting the Swagman Roamer LT Roof Rack # S80510 you were looking at on your 2015 Jayco Sport 12UD camper with the aluminum trim over the mounting location. The key things will be making sure that you hit structure underneath the trim, and that you seal the drilled hole with Sealant # 34427034145-1 to prevent leaks.
