Sashco 13030 10.5oz Sashco Sealants White Lexel Adhesive Caulk, 10.5-Ounce

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.

this is the best caulk. seals quickly and holds strong. is thick, yet it spreads easily. only needs one application. the clear color is versatile. 2 pack is a good value

Bought 8 of these...use on everything outside

Works great

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.

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.

Swimming pool tile remain attached to the pool wall

This stuff is amazing, seals, waterproof. It is worth the price.
