Common questions
What size joint knife should I start with for taping?
A 4 to 6" knife for the tape coat. The 4" works best in inside corners.
01540 or 01550?
The blades are identical. The 01550 adds a nail-setting Hammer Head butt. Choose it for remodel work.
Can it do the fill and skim coats?
No. Those need a wide taping knife to feather the seam flat.
Paper or mesh tape?
Paper in corners. Paper is generally stronger. Use mesh only with setting compound.
