I have been doing apartment maintenance for over a decade and have caulked hundreds of tub surrounds, vanity and kitchen counters, etc.. I have tried my finger, other caulking tools, a credit card (expired!), etc., and this is by far the best caulking tool I have found. The reason I gave it only fou...r stars is the cost. Seems a bit pricey.

I have a few suggestions about the product as well as one (the last one) for using silicone caulk in general.

First, do not apply too much caulk when you run the initial bead. How much is too much? See my second suggestion.

Second, practice. Run a consistently sized bead of caulk, use the tool and then scrape away the caulk and toss it. Do it again. Yes, I know, you are "wasting" caulk. If you want a professional looking job, waste some caulk by practicing. You will find the appropriate bead size through practice. Obviously, the correct bead size will be determined by the edge you are using. The larger the edge the larger the bead size. Practice. Also, begin with a small hole in the caulk tube nozzle. Not enough caulk? Cut a slightly larger orifice. Remember, you can make the hole larger, however, you cannot make it smaller.

Third, keep the tool perpendicular to the surfaces. If you have seen the ad on TV, pay attention to how the demonstrator holds the tool.

Finally, fill a spray bottle (like a windex bottle) with isopropyl alcohol and lightly spray the bead and the business side of the tool. It will make the tool glide easily over the caulk. (You can use this trick with any caulking tool including your finger.)Read more Less
