  • Great Product!
Color: White Size: No Size
Thanks to Mother Nature, and a moderately damaging hail storm, my camper trailer suffered some damage to the 2 roof vents, with some fairly large chunks completely knocked out. I had already replaced the roof vents in 2017, due to a worse hail storm, and wanted to consider an easier fix. So...I used Titebond glue to adhere strips of drywall repair mesh (comes in a long roll, like drywall tape) over the gaps and to stabilize the multiple cracks. I put a small piece of painters' blue masking tape on the inside of the vent where the mesh was open to the interior, as I couldn't find a good size chunk of the roof vent plastic. The following day I used the Flex Seal Max spray over the entire surface of both roof vents. I sprayed it on very thick, to completely cover the mesh tape. The consistency of this product is obviously thin enough to produce an easily-sprayed product, for better aesthetic coverage, but it was probably a bit too thin for my application. I also used a 2" disposable foam brush to try and get thicker coverage over the mesh taped areas, once the product had started to set-up. The product's solvent evaporates fairly quickly, so I made another spray pass over the hand-brushed areas for better looks, and in case I had disrupted the coverage, to avoid leaks. The job looks great and appears to be adequately sealed. I'm also hoping that the 'rubberized' coating may be more hail resistant. Plastics at Denver's altitude take a real beating from UV exposure, so I'll see how this idea pans out. This spray also may be a good idea as a preventative to avoid moderate hail damage. Update: after waiting several days for the Flex Seal to cure, I tried to remove the small strip of blue painters' tape from the inside of the roof vent. The Flex Seal stuck to it pretty bad, and stripped off a little of the product. Luckily, I still had some left in the large, 17oz can, and made another pass to seal off the few small holes. Hopefully I'm now done with this project! ... show more

  • Great product - not so great brown color
Color: Brown Size: 14 oz 2 Pack
I'd used the white flex seal on a wood bulkhead cellar door. It has worked incredibly well. The wood under neath is still in pristine condition 10 years later, but it needed a refresh as it was getting dirty looking, so I was excited to see that now Flex Seal comes in brown, I did not expect it to match other dark brown trim, but, wow I did not expect it to be this color!! It is more like a greenish olive bronze shade not true brown. I highly recommend Flex Seal their products are AMAZING - but if you are looking for a true brown shade, I recommend painting with the color paint you want and then applying the clear Flex Seal over the paint, as their website suggests. ... show more

  • How to get the best out of Flex Seal and products like it
Color: Brite Size: 14 oz
While not perfect for every application, Flex Seal actually does what it advertises. After reading a lot of the one star reviews, I can see there are a lot of problems with the way people are spraying the product on as well as issues with what is expected. Here are a few tips to get you the best results you can out of a product like this (there are many and they are all basically the same) 1. Choose the right kind of Flex Seal. This may seem obvious but there are several kinds of flex seal and they are all used for different things. I. First, the rubber patch/tape is used for large cracks and or holes where you have full access to the area around it. The tape is very thick and can sometimes be unruly. Lay it flat out, cut it, and then roll it while keeping tension on or slap it on like in the commercial. Do not think you are going to move it around and reposition it. You won't. It's a one shot deal for best results. The tape, size to be at least 3-4 times bigger than the hole you are trying to close up. The tape can handle the most pressure in the product line. You must have enough surface area for the tape to get a good grip around the hole if you plan for it to take any kind of real pressure. II. The roll-on stuff is great for large coverage where you want to get fancy putting on thicker and thinner coats here and there. It applies like a sticky paint. I would say that the paint is the most "accurate" because you will use a roller or a brush to put it on and you can make sharp lines, stuff more material in gaps really easily, and handle uneven surfaces nicely. III. The spray is for quick easy jobs as is the weakest under pressure. It's great for sealing things like sky lights, thin plastic objects, joints on gutters etc. Anything that won't see a lot pressure behind it. It's harder to put on thick, but if you apply it like spray paint you can do amazing things with it. Thin, even coats, in a sweeping motion, over and over again and you can cover just about anything. IV. The flex seal one shot caulking is really just like almost any rubber/silicon caulk. I've only used it once and was not all that impressed so I tend to stay away from this one and use 3M stuff instead. 2. Pick the right color for your application. The Clear does NOT stay clear. It has a tendency to turn yellow in the sun. If you don't mind that, or won't expose to sun or much light, then the clear is fine, however, I usually stick to white or black. PRO TIP: You CAN mix the colors of the roll-on to make different levels of gray. I am sure Flex Seal would frown but it works for me. It takes a lot of churning to get it all mixed and not streaky. Your mileage may vary. 3. Use for the right jobs. Don't expect this to seal high pressure water or stop a leak in a tire. There are limits to its flexibility too. When you can, seal from the inside AND the outside. Use the tape whenever possible as it works the "best" of the products and is insanely tough. 4. A little goes a short way. It doesn't cover as much area as you would think. Always get extra. 5. Using a screen door in the commercials wasn't an accident. When covering a large area, stick a screen type material to the area and screw it in place. Then use flex seal to cover the gaps in the screen. Use many coats, go slow and the kind of gimmick you see in the commercial is possible. If you cut a 4 inch by 4 inch hole in something, don't expect flex seal alone to seal it. Use a backing material. 6. If you are getting bubbles in the flex seal spray you are putting it on too thick. Relax. Put on thinner coats and apply slower. Give it a few minutes to get tacky, then retry. 7. Final PRO TIP: CLEAN THE APPLICATION SURFACE. This one is a no brainer, but over and over again I read about people not doing the prep work. Using de-natured alcohol is best if you can. It leaves no residue and on a clean surface like that it makes Flex Seal stick like you wouldn't believe. This is the most important thing other than choosing the right kind of flex seal to use IMHO. Good luck! P.S. One more thing you can do is use painters tape or the like to cover from over-spray. Really if you treat it like a super thick paint, most of the same principles apply. ... show more
