SASHCO 13080 Lexel Synthetic Rubber, 10.5 oz, White, Voc

A very good caulk, once you understand how to work with it.Pros; Sticks to anything (except old cured silicone, but then nothing really sticks to silicon)Easy to tool if tool is dipped in mineral spirits and if tooling is started quicklyEasy clean-up with mineral spiritsCons: Sticks to anything, especially you and your clothesSkin forms very fast and if not tooled before skinning starts, then result is not smooth.Suggestions: Have everything, mineral spirits, smoothing tool, clean-up rags, ready before applying the first bead. Don't wait more than 1-2 minutes before you begin tooling and complete the tooling within a couple of minutes. Make sure smoothing tool is repeatedly dipped in mineral spirits, otherwise tool will also pick up caulk. Your finger is a great smoothing tool. For big jobs (many minutes in duration) work in small sections; apply bead, then tool, and repeat again for each section.

I’ve been using it for years, and simply put it is the best petroleum based product there is. This will even adhere to wet surfaces. Great company too.CON-(1)I don’t always have time to order this, and I’m just a homeowner. If I were using it commercially I would just buy it by the case and have it available all the time. (2)The shipping purports to be free, but when it can be found locally the retail is about $10. Ordering it is $14.99, so you are really paying a hidden shipping fee.Overall this stuff just flat out works, and it can be tooled using a wet finger dipped in sudsy water, or mineral spirits if you need to go over a larger area.

Applies like smooth white velvet. While it's shiny on application, it becomes less so as it dries. Be prepared to work quickly and don't apply a long line because it starts to develp a skin within seconds after leaving the container. Be ready to smooth the caulk using your finger or a latex finger sleeve and mineral spirits. I just did a shower stall; if you want nice lines of caulk, you have to use blue painter's tape and remove the tape within 15-20 seconds of applying the caulk.

This caulk doesn't dry out. Last for 10+ years.. Great for underwater jobs as well.

I tried to get this caulk to stick to galvanized metal. It kept peeling away and sticking to my rubber gloves instead.

In the past, my go-to caulk was GE's paintable silicone sometimes referred to as XST. Lately, I started to notice yellowing and other issues that I never saw in the past. With my recent purchases, I decided to try something new. Research showed that this was the best caulk in the same realm as the XST. From a performance perspective, it does not disappoint. This stuff sticks to anything! The only downside is that it is a bit messy when tooling. If you need a more toolable, high-performance caulk, I recommend Big Stretch. Otherwise, this caulk is the best performing caulk I have ever used.

It works but it is hard to "tool" into a proper / acceptable shape. I have tried many ways, the best is to simply use a 1:1 soap-water solution and your finger. You have to tool it immediately after application, wait 30 seconds and it does not tool anymore. You get ONE chance to tool it, that's it. Make a mistake and end up with a total mess. You cannot wipe it off like most silicone or acrylic caulks and start again (in case of a mistake or mess). This product will make round-round beads which are almost impossible to clean out (it dries up too quickly). That is happening because, basically it is an adhesive being sold as caulk. For applications like acrylic shower pans, it is supposed to be better than silicone. People say silicone wont stick well to shower pans, and that is where I used it.

One of the best sealants I’ve used. Easy to apply as it is very workable and sets to a rubber that has impressive elasticity and is paintable. To my mind it is better than 100% silicone bit will have to see how it performs after several years.
