Pro Caulk Review

Updated August 15, 2016
Pro Caulk
Bottom Line

Pro Caulk is a simple tool that is advertised as being the solution to messy caulking projects. It's a collection of small, silicone discs that produce different sealing edges when they're run along wet caulk. Simply apply the sealing compound of your choice to tile, select the appropriate Pro Caulk disc and slide it along to get a perfect edge. The tool will collect the excess product, making the clean-up process a lot easier.

Pro Caulk has been tested by many reviewers and customers, and the majority of them say the tool works as advertised. They find the tool simple to use and say that it leaves a smooth finish most of the time, though it depends on the surfaces being worked on. A few users say the material that Pro Caulk discs are made from isn't very strong, and both happy and dissatisfied users note that smoothing caulk with their fingers yields the same results, making them wonder if Pro Caulk is really worth the price.

  • Easy to use
  • Works with a variety of sealing compounds
  • Doesn't work on textured surfaces
  • Made from flimsy material
  • No more effective than using your fingers

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 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.

Pro Caulk: Does it Work?, 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.

Does It Work: PROCaulk, Editors of KLRT, May 4, 2009

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.

Deal or Dud: Pro 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.

Pro Caulk Review: Do As Seen On TV Products Work?, 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.
