![]() this is self leveling and I would imagine it would run if applied to a vertical surface. This sealant can be used in place of ProFlexRV sealant for seams and around vents or anything that goes through the roof of your RV. I have not used this sealant but it comes highly recommended. I highly recommend ProFlexRV sealant for all seams in your RV. ProFlexRV sealant between the tub and walls of our shower has out performed all other sealants and still remains solid. ![]() I used a few different types of bathroom sealant in our RV tub resulting in failed seals. The sealant remains a little tacky allowing dirt, leaves and such to stick to it as well. I have noticed the outside of the bead applied dries quickly but the inside remains soft for about a week. ![]() This sealant is incredibly messy and steps to keep your work area clean are highly recommended. I have used this product to patch leaks in seams I have dried and cleaned with acetone between rain showers and have had great luck. While holding the tube in place against the seam, squeeze the trigger of the caulking gun pushing sealant out of the tip down into the seam while slowly sliding the caulk application tube along the seam.įrom what I have read, ProFlexRV sealant is the very best sealant for seams in RVs. Squeeze the trigger to push sealant out of the caulking tube to fill the application tube and then exit the tip. This allows the sealant to be pushed down and in front of the caulk application tube filling any gaps with sealant. The application tube of the caulk should be directed 90 degrees to the seam. Hold the caulking gun so the application tube is perpendicular to the seam to be sealed. Use the thin rod that is on your caulking gun to puncture the caulking tube’s seal by sliding it down the application tube. You can always cut more away if you need a thicker bead of sealant. Use Pro Flex RV sealant with a normal caulking gun.Ĭut the tip off of the sealant’s application tube very close to the tip so you can lay a thin bead of sealant. Once the surface has been cleaned well with acetone, a new bead of sealant can be applied to the seams of your RV. This step is crucial before applying new sealant. The acetone will easily remove small loose pieces of sealant and any residue and oils on the RV material surfaces. The fresh sealant will adhere to good sealant left behind.Ĭlean the area well with a white rag soaked in acetone. Sealant that is difficult to remove can stay on the RV. Be very careful not to dig into any RV material when using the metal scraper. I use a flexible metal putty knife to carefully slice through the bond of sealant and roofing material. Use a nonmarring plastic scraper to scrape bad sealant off of plastic or any painted surfaces. That bad sealant needs to be removed before new sealant is applied. This will cause expansion and shrinking of the sealant and the materials around it causing the sealant to pull away opening the seam. Our RV sealant is subject to high temperatures and low temperatures throughout the year.
