I am a professional for 40 years now and I have been waiting for a tool like this for a long time. The efficiency is great due to it's precision and speed. The fact that you can use any tape brand is a big +
The precision of this tool is amazing. The only thing that you have to consider is that you need to re-loop the tape after every run and the max. width is 1 inch! You'll get used to the looping, so this will get better over time.
Have one in my gear all the time. Can't use it in every situation, but definitely a huge time saver!
I have been a DYI painter for over 45 years, and I have to to tell you I was skeptical at best when I saw the Masking Master advertised. We all know how tedious and difficult masking baseboard and ceiling molding can be. I tried the Masking Master and was really impressed. I did both my baseboard and my ceiling crown molding and it worked great on both. The baseboard was easier because I could do it all in one run. The ceiling was a little more effort as I could only do arms length, cut it, and then overlap the tape on the ceiling molding, for another arms length. I was worried that the ceiling wouldn’t come out as nice, but again I was presently surprised. I use the green multi surface Frog Tape, .94 inch which creates a great seal. I was worried there might be a thin layer of paint on the molding, but it came out clean.
I would highly recommend this product and it was easy to use and made it faster to tape the job.
My only suggestion would be to make a Masking Master that can handle wider tapes.
