The Bull Tool

The Bull Tool

The Bull Tool is utilized for painting a perfectly straight even line on a bullnose corner and painting a perfectly curved line where the bullnose corner meets the baseboards.

Here is an example of how the Bull Tool can help you paint bullnose corners

There are two parts:


The Bull Tool

The Problem: just eyeballing your paint lines causes the transition lines to be uneven and choppy.

The Solution: the Bull Tool creates a perfect straight even transition line on a bullnose corner every time. It compliments your painting process seamlessly when paired with the Pre-Cut Painter’s Tape.


Pre-Cut Painter’s Tape

The Problem: using multiple layers of tape to cover your baseboard edges is time consuming, bulky and causes the paint to bleed.

The Solution: the Pre-Cut Painter’s Tape creates perfect even baseboard edges on bullnose corners. It compliments your painting process seamlessly when paired with The Bull Tool.

It’s made for the Do-It-Yourself amateur AND the Professional painter.

  • It easily creates a perfect, straight even line and a perfect curved line at the baseboards EVERY TIME!
  • It’s compact, lightweight and fits in your pocket!
  • It’s easy to use.
  • Also, for the do-it-yourselfer, it’ll save you a lot of frustration & a few less arguments with your spouse.
  • Fits 3/4 inch bullnose corner (sizes 3/8 inch and 1 1/2 inch – coming soon!).

Financial Benefits

Tape/prep one 7 foot tall corner *10 – 30+ minutes
Paint line is not straight and is uneven
*Less than 5 minutes
Paint line is straight and even
Tape/prep one archway (two 7 foot tall corners and overhead 40 inch arch *20 – 60+ minutes
Lines are not straight and are uneven
*Less than 10 minutes
Paint lines are straight and even

* The times are based on the do-it-yourself painter. Some do-it-yourself painters reported spending 2 -3+ hours getting the entire archway taped and they reported crooked and uneven lines without using The Bull Tool. Professional painters should expect faster times with perfect, even and straight lines. Some professional painters have been timed less than 2 minutes for taping an entire archway.


I just wanted to let you know that your tool worked perfectly for me!!! The Bull Tool is a lifesaver and I only wish I would have found it sooner! Like I told you over the phone- I have tried several other methods of painting the bullnose corners and NOTHING worked like your tool! I painted the archways in my house and your tool allowed me to choose the exact placement of my color transition on the rounded corner. The other plastic tool I ordered from Amazon only gave me 3 options for marking around the bullnose, where yours gave me 10+. I did mark my lines every 2 inches around the archways because I wanted more guidance for the tape, but the process was extremely quick, easy, and consistent... Continue Reading

Matthew, I wanted to show you how great The Bull Tool did on my corners. It looks like a professional did them. Thanks so much, and my wife is happy with them also. Thanks again! View Photos


Great product!! Anyone painting the inside of their home with rounded or bullnose corners needs this.


I used the Bull tool not only for the rounded corners when painting but also the square corners when I was painting my new baseboards. Ensured my painting looked really sharp!


I have used bull tools and they have shortened my time painting and consistently gives a clean look. It is a great product.

Thanks for sending a sample of the bull tool, my guys have been using it on all my interior jobs with bullnose corners. We normally guesstimate where our color transition lines will go with subpar results. Now with the bull tool we can measure where our tape will go with great results “Straight Lines”.

This is something realistically anyone can use! I met Matt through his chiropractor business. At the time I was building a home and asked if I could try a pack of his Bull nose corner tape, it cut our project time way down.  It took us minute to get it right but then we moved along and it made the corners look great.


Thanks for sending over the pre-cut painter’s tape, I’ve been using the pre-cut tape for all the houses with rounded baseboard corners. It saves us a lot of time; we normally put multiple small pieces of masking tape on 1 round corner, now we just put 1 pre-cut painters tape on the top of each rounded baseboard top.
