Lexel White 10.5 Oz (1 Pack)

I've used at least 20 different types of sealants over many years. I am here to tell you that this one is far superior to anything else on the market. It is indestructible and adheres to the listed surfaces with unbelievable tenacity. I've used it to fill cracks in concrete foundations and patios, both indoors and out Once dry you literally cannot remove it. I live in the northeast. Winters are harsh with wide temperatures variations which cause concrete cracks to expand and contract significantly. I've had no issues with Lexcel failing on concrete even after 15 years. I have also used it to fill cracks in plastered walls since it is paintable. It's the last time you'll need to fill them. Any other paintable sealer will eventually fail in this application. If you don't like doing things twice or more times, this product is for you. For the record, I leave very few reviews on products I use. Sashco has earned this one bigtime.

I am giving this 4 stars until some more time has passed but so far this has been a 5 star product. I used it to calk a fiberglass bathtub onto the tiles in our bathroom. I already tried using the other brands like Lanco and found that they dried up and turn yellow and then shrink and shrink until they start to lift or develop cracks. The Sashco is different, it seems to be an oil based calk that sticks very well and is bright white and when cured there is no shrinking, so far (2 weeks). I also like that it creates a very smooth surface when put on, a kind of glass like surface unlike the Lanco or 3M stuff that got very uneven and rough. Drying time to first shower usage is about 24 hours and after 72 hours it is pretty solid. The packaging says 30 days to full curing time which is pretty normal with most caulk. One word of advice, when spreading this on do it in one pass and DO NOT make a second pass over the caulk. It develops a glass like skin almost instantly and a second pass ruins that as the surface layer dries within seconds. (Note See update #2 below) Update: Over 6 months and only a small amount of shrinkage. It still has that slight elastic feel and is still shiny and new looking. By far this is the best Caulk I have ever purchased. I have now given it 5 stars. Update: Aug 2019 I am now at the 13 Month point and I have purchased two more tubes to redo everything in the house with this Caulk! The original job is still looking great, it did develop some mildew at the 8 month mark but I was able to clean it off easily. I noticed on the fine print that it says the caulk can be smoothed with your finger wetted in MINERAL OIL. Also they say it can make the bead look more even as you can work with it longer. Also Mineral oil is what they recommend for cleaning up any messes. This brand is now the only one I will use going forward as it does not shrink very much, does not get dirty or mildewed very easily and it has a really nice sheen that has so far kept a fare bit of an elastic feel to it. Update Aug 2021 I have now used this on just about everything in my house that needed Caulk. My first bath tub application is just about four years ago and the caulk is still in perfect condition and is still pliable when I press my finger nail into it. This thing is amazing, it does not harden up with age and crack like every other brand I have tried before. I used the Lexel to seal an outdoor vent fan on the side of a concrete building. After 24 hours we realized that the 12" fan could not work in that location and it would have to be removed and the hole filled back in with cement. As we pulled the four concrete screws and tried to remove the Fan it would not budge. We ended up spending 30 minutes prying it free from the Lexel seal with screwdrivers and razor blades. In the end the concrete surface broke away in 1/4" thick bits that were stuck to the metal on the fans rim. This stuff sticks to metal and concrete just as readily as it does to fiberglass and tile. It is just incredibly strong and durable.

Great product for sealing our motorhome, it outperforms silicone. One thing to note is that it sets up very fast; I had only 20-30 seconds to smooth it with mineral spirits before it started to set.

I used this to recaulk my RV (not on EDPM roof). I have used both the clear (which is extremely clear) and the white. Fumes are strong but if using outdoors you will be fine. It is a bit expensive but worth it. This stuff starts to skin almost immediately so you must tool this very quickly, you can only lay down a few feet at a time max. I used Windex on my finger like you would with silicone and it tools very smooth if you act quick. It will stick to almost anything and is very hard to remove so keep that in mind and try not to mess up. I believe this will hold up for a very long time and seems far superior to what came on the camper. I am sold on it and will never buy silicone again.

This stuff is a lot more messy than regular caulk. It did paint well but you have to wait 2 days. I had trouble getting it to stick in one spot even though it was cleaned well and sanded.

Lexel is going to be my go-to sealant from now on. I used it where the installer left too large a gap between the acrylic tub liner & tub surround. I tried regular sealants several times, but they sagged & an opening would eventually surface, especially when the weight of a full tub placed stress on the seam. Another attempt using silicone caulk was a big disaster as the silicone wouldn't permanently adhere to the acrylic. The Lexel was a cinch to apply, not drippy, & if you smooth it with a wet soapy finger as shown in their video, you get a very professional-looking application. The stuff is purported to stick to itself, so I just got through adding some to a few areas where I may have been a little too frugal in my first application. So far, so good! For clean-up, I used Goo Gone and a cotton swab on the nozzle, then washed it with dish soap. I put some plastic wrap over the tube opening, reattached the nozzle tightly and capped it with a recycled cap from another product. The Lexel was in perfect shape 2 months later! Will definitely buy again.

White is so much better than clear for RV sealant. Used to seal up all the exterior doors and windows. No matter how hard you try…it will make a mess…so highly recommend using blue tape.
