RV/Trailer Sealant & Adhesive

Not inexpensive, but works very well. Sticks well to many different surfaces.

used this for a repair that needed waterproof and permanent - this applied on easy and so far 100% resolved issue! I used AI to recommend product off amazon after uploading to AI a photo of the damage and this is what it recommended.

Before I retired, my company was excellent at ceiling water leaks. Sika was the best product in areas exposed to ultraviolet light. I recently used it when installing a new skylight on my RV. Knowing that it’s difficult to clean up, I blue taped all edges and had rags with solvent nearby. The job went very smoothly, I was impressed how easily it adhered and spread evenly. Cleanup turned out to be no problem for me.

This stuff is robust. It’s easy to apply and finish, looks great and holds up to standing water (so far). On the pricier side but you get what you pay for, it should hold up!

Product works great on my RV, but this last tube I purchased had an “expiration” date that’s picky 3 months from the time of delivery. I’m not sure what happens after it expires, but why would Amazon send something like this so close to the expiration date? I keep a tube with me for RV repairs.

I used Sikaflex to adhere a roof wing to the back windshield of my car, and I’m seriously impressed with how well it worked. The bond is incredibly strong and feels permanent once cured. I let it set for about 24 hours before driving, and even after months of highway speeds and temperature changes, the wing hasn’t budged at all. The application was pretty straightforward, it has a thick, tacky consistency that gives you enough working time to position everything correctly before it starts to set. I’d recommend taping or clamping the part in place while it cures, because it does take a while to fully harden. Once cured, it’s flexible enough to handle vibration and movement, which is great for automotive use. One thing to note: this stuff is messy. It’s sticky, and once it gets on your hands or paint, it’s not easy to remove. Wear gloves, mask off surrounding areas, and have some cleaner or mineral spirits ready. Overall, Sikaflex delivered exactly what I needed, a strong, weatherproof, and vibration resistant bond that’s holding my roof wing securely in place. It’s not the cheapest adhesive, but it’s worth it for the strength and reliability.

really good adhesive/sealant. I have used several other cheaper amazon brands and it lays significantly smoother and like a thick cake frosting consistency - it also hardens and connects with much stronger bond. Highly recommend using this and paying the price over the cheaper stuff out there

Great product, needed this to reseal around some pipes and wires at the underbelly of my travel trailer. Wear gloves, this stuff is messy. Looks and feels like it will hold up to the test of time.

Very good

Buen sellador excelente para celular y buena. Marca

It’s SIKA, it does the job right. Replacing the Water heater on RV and original install got over enthusiastic with the opening size. Used lots of SIKA to fill gap before applying the butle tape and the retaining ring to make sure no water leaks from rain

Great brand always works
