I’d been meaning to try Caulk Singles for awhile now — I got a sample last year when they first hit the market. So over the weekend I decided to give one of the 1.25 fl. oz. packages a try, caulking the line where our bathtub meets the floor. One tube would have done the job if the space had been a little more narrow — the Caulk Singles site gives you guidelines on how many packages you’ll need for a typical job. The package was easy to open, the caulk dispensed easily, and it stayed fresh when I closed it up overnight with a bit of tape. But the very nature of the Caulk Singles package is, of course, that you won’t need to go to the same lengths as you do to keep a large tube of caulk fresh, because one application and it’s all gone. The packages press flat, resulting in much less waste than the kind of caulk that requires a gun. The only thing I didn’t like was that it was a little harder to control the dispensing size — tearing off the top means you pretty much take what you get — so I did a lot of touching up in spots where the bead of caulk was much thicker than I’d have liked. Still, it’s a convenient product I will probably try again. Get them for $2 each at Lowe’s. –Mary T.
