Our Analysis
Read Amazon Reviews

Several local television news programs give Pro Caulk a hands-on test, including KFVS in Cape Girardeau, Mo., which finds that the tool works well on flat surfaces and gives it an A grade. WMBF in Myrtle Beach/Florence, S.C., says that Pro Caulk is no substitute for a caulk gun, but that it's a useful tool for those with little to no experience working with caulk. KLRT in Little Rock, Ark., has trouble getting a smooth finish and declares Pro Caulk to be a dud. A reporter for Popular Mechanics tests the tool and is impressed with how it smoothes both straight lines and corners. Reviewers on Amazon.com are mostly happy with Pro Caulk and how easy it is to use, though a small percentage didn't get the results they wanted and found the tool to be flimsy.

In the end, most seem to find Pro Caulk to be useful, particularly for those new to caulking projects.

Lauren Keith, April 29, 2009

As part of KFVS's regular "Does it Work?" segment, Lauren Keith tests Pro Caulk with a couple of Habitat for Humanity volunteers. They first test it in the furnace room and find that Pro Caulk doesn't leave a smooth finish when used against a textured wall. A second test in the bathroom fares better, as the flat bathtub surface helps to make a smooth caulk line. It does take two swipes with the Pro Caulk to get a nice finish. Overall, they give Pro Caulk a grade of A, saying that it works well when sealing a flat surface.

In a regular "Does It Work?" segment, WMBF tests Pro Caulk on some countertops with a professional carpenter. They find that it works well to create smooth caulk lines, though it may take a couple of tries to get it right when used in corners. Pro Caulk also successfully collects a lot of the excess caulk, making the clean-up process a lot easier. While the carpenter says it's no substitute for a caulk gun, he does think that Pro Caulk would work for someone who doesn't have a lot of experience working with caulk.

Editors of KLRT, May 1, 2009

A KLRT reporter tests Pro Caulk with some flooring experts in one of their "Deal or Dud" reports. They find that the tool doesn't leave a perfectly smooth finish, as it claims to do. They also test the Pro Caulk grouting tool and find that it leaves behind too much messy residue. Saying Pro Caulk isn't the tool to use for a project as complex as caulking, they deem it a dud and say that they get better results just using their fingers to create a smooth finish.

Harry Sawyers, Dec. 17, 2008

Harry Sawyers tests Pro Caulk while sealing some exterior windows. He says the tool creates a smooth seal in both straight lines and in corners, and that it is far superior to using his fingers to smooth out the caulk. Sawyers says Pro Caulk works as advertised and would be a welcome addition to anyone's toolbox.

Contributors to Amazon.com,

The most common complaint is that the Pro Caulk tool is flimsy, and many customers -- both satisfied and not -- wonder if it's worth the price when they get the same results using their fingers or a plastic spoon to smooth out caulk. The average rating is 3.3 out of 5 stars.
