Mechanical Taping Tools

After years of traditional drywall finishing, I decided to give mechanical taping tools a try. I'd heard mixed reports about them but hadn't seen them in use. Ames Taping Tools conducts a one-day class on using mechanical taping tools in Leola, Pa., so I made the trip, assuring my wife as I left that I was only going to gather information. The training from the Ames crew was excellent, and I was really impressed with the tools. Needless to say, I came home with a complete set and a very convincing argument in my defense (at least from my perspective) for renting them. (Although the tools are expensive to purchase — ranging from $3,000 to $5,000 for a complete set — Ames doesn't sell their mechanical tools; they only rent them.) I rented the tools for about a year, and then finally decided to purchase a similar set from Wilco Drywall Tool for about $3,500. Now, whenever I tape a large job, I use the mechanical tools. The automatic taper applies paper tape and the proper amount of joint compound simultaneously as the tool head is rolled along a seam or inside corner (Figure 16).

An automatic taper applies paper tape and compound simultaneously to seams and corners. Loading pump. Many of the mechanical tools have to be filled with joint compound. The loading pump comes with different attachments for the various tools (Figure 17). It's lightweight, stable, and easy to clean, and it has a reversible handle for left- or right-hand pumping.

Figure 17. Mechanical taping tools must be loaded with compound using a special pump. Attachments adapt the pump to various finishing tools.A corner roller embeds the tape into the compound, following the automatic taper in inside corners. The 3-inch adjustable corner finisher wipes down and feathers the compound after the corner roller embeds the tape. The 3-inch corner finisher can also be used to apply and smooth the finish coat on inside corners, but to do this, joint compound has to flow into the finisher, then onto the corner (Figure 18).

A corner roller embeds tape in the compound following its application by the automatic taper (top). An angle applicator attaches

to the corner finisher to deliver compound to the surface for tooling. The 3-inch adjustable corner finisher smooths and feathers the compound after the tape is embedded by the corner roller (above). An angle applicator is essentially a box filled with joint compound that attaches to the corner finisher. Joint compound is forced out of the box and through the corner finisher, which in turn smooths and feathers the joint compound. Flat boxes, or mud boxes, apply and smooth the joint compound for the filler and finish coats over taped joints. These boxes come in different widths: 7, 10, and 12 inches. I use the 10- and 12-inch models (Figure 19). I like the uniform results that I get with the flat boxes. The width of the seam is determined by the box, but the box's trowel edge can be adjusted to match the precise crown of the compound previously deposited on the seam.

An adjustable curve in the blade ensures a precise, feathered crown on flat seams.Myron Fergusonis a drywall contractor in Broadalbin, N.Y., and the author of Drywall: Professional Techniques for Walls and Ceilings.
