| Tower Tech 2 - Acrylic Urethane Elastomeric Sealant - 10.1 fl oz - Clear

Great caulk, inside or out. Tough yet stretchy when cured, and easy to work with. Shrinks less than most too. Adheres well to anything I've tried (not the impossible to stick/glue low surface energy plastics like HDPE, of course!) Doesn't tend to harden in the tube prematurely, either. Soap and water cleanup. My new favorite!

Nice and clear when dried. You have to work fast and in small sections at a time to avoid premature drying but otherwise easy to work with. You can also use a small spray bottle with water in case it’s a sunny day when you’re working and you’re fine. Ppl say this is what the pros use over the cheaper Home Depot brands so I hope it holds up. I been using this outdoors to seal windows and cracks on the side of my garage wall and so far it works real well. Dries perfectly clear and fast. Only downside is a slight gloss so I’ll have to paint my garage wall to hide the sealed cracks. Very easy to use.

I was in the construction industry for years. The builders I worked with always used urethane caulk because of its long term reliability. Sticky and durable.

I used this product to seal a joint between a concrete floor and a wooden wall in a storage room. The gap was generally small but the size varied; to compensate, I used a 1/4-inch backer rod where necessary. After cleaning the area and installing the backer rod, I applied the sealant with a caulking gun. The sealant flowed into the gap easily and smoothly. I did some final smoothing by dipping a finger into warm, soapy water and drawing it across the bead. The weather here is currently cold and humid so drying time was slow -- in this case, two days.The only suggestion I have is to apply the sealant slowly and make sure you fill the gap completely -- it may take a bit longer to dry but you'll have a lasting water-tight seal.

I must not have read the description correctly because I thought that I was getting two of these instead of one. I would not have ordered just one and paid such a high price with taxes and shipping.

Best caulk I have ever used on trim prior to painting, and I have done a lot (amateur here). Began using it three years ago and in those applications, have never had a shrinking/cracking problem, with either oil- or water-borne alkyd primer or paint. So glad I found an alternative to that other "better known brand." Highly recommend.

Excellent caulk

I wanted to give it 5 stars, but I removed one, because recently an area with a thin crack appeared, between me ceiling and the crown molding.
