Semi-Automatic Tools

The 7" knife works best for wiping tape that is applied with the automatic taper.  Use the optional extension handle (sold separately) when wiping ceiling joints which avoids the need for stilts or scaffolding.
TapeTech has two different tool categories for finishing internal corners.  Corner Flushers and Corner Finishers If you have what TapeTech refers to as a corner flusher, there is no way to adjust the amount of joint compound the tool leaves in the corner. However, our Adjustable Corner Finishers, models 48TT and 48XTT, have adjustment arms on the back of the tool that allow you to increase or decrease the amount of pressure, thereby allowing you to leave more or less compound on one side, or both sides, of an internal corner. Models 40TT, 42TT and 45TT Corner Finishers do not have adjustment arms.
You can purchase Semi-Automatic Tools through any of our authorized TapeTech dealers.  To locate the nearest dealer, visit our Dealer Locator.
Yes. Simply loosen the screws on the reverse side of the skid, move the skid to desired location and then tighten the screw.
Minimal lubrication is needed for the semi automatic tools. Simply apply a small amount to the piston (rubber) of the compound tube.
Basic cleaning can be done by pulling back the plunger to fill the tube with water and then push out the water. Repeat this step several times. The compound tube can also be thoroughly cleaned by releasing the nose cone clips and the plunger clips.  Remove these parts and clean with water and brush.
There are two options to fill the Compound Tubes. Option, 1 - Simply place the ball outlet into the bucket of joint compound and pull back on the plunger handle to fill the tube.  Option 2 - You can use a standard loading pump with a Goosneck Adapter to fill the Compound Tube.
The Compound Tubes are an excellent tool for applying joint compound to the outside corners when installing paper faced bead.  Simply add the TapeTech Outside Applicator Head (sold separately) to the Compound Tube to apply a uniform layer of material for this application.
Yes.  You can visit us online at to view schematics that will show all replacement parts with their associated part numbers for easy ordering.
Yes. You can use the Flushers to wipe out the angle tape that has been applied with the automatic taper. Most finishers will still use the Corner Roller to embed the tape but you can also purchase the Corner Flusher Creaser Wheel Kit which can be installed onto the Flusher.
Keeping your Automatic Taping and Finishing tools clean is a key to proper operation and long tool life. An important part of cleaning the Automatic Tapers (04TT & 05TT), MudRunner® (14TT) and Corner Applicators (35TT & 50TT). TapeTech offers an EZ Clean Wash Adapter (#053808) that connects to hose nozzles that feature a threaded front end (e.g Gilmour 573TF). Just attach this adapter to your hose nozzle and then insert onto the filler adapter of the tools. Turn on the water, squeeze the trigger of the hose nozzle and quickly flush the joint compound out of the filler adapters of the tools without getting soaked! There are two adapters per package. These adapters, along with a hose nozzle, are also included as part of the 501B Taper Cleaning Kit and 501H1 Pump Cleaning Kit.
Yes. There are three adjustments that can be set on the Power Assist™ arm that connects the spring to the radius plate of the TapeTech Power Assist™ Finishing Box. The Power Assist™ boxes are factory set on the second setting of the Power Assist™ arm. To increase spring pressure, move the spring up to the top of the arm. To decrease pressure, move the spring to the bottom setting of the arm.
To fill the TapeTech Power Assist™ Finishing Boxes with joint compound, pull the pressure plate out to the fully open position. The pressure plate will catch in the toothed prawl (#212088) and be held there. There is a lock (#212087) mounted on the right side of the pressure plate that will secure the tool in the fill position. The finishing box can now be loaded with joint compound using the filler adapter and the loading pump. Watch a video of loading compound into finishing boxes here.
Something is likely keeping the valve open (dried compound, sediment, dirt).  Try cleaning the valve thoroughly with pressured water and a brush. Inspect closely to see if there is anything in there and apply Bazooka Oil.  This should resolve the problem.
FibaFuse will go through the taper.  Fiberglass mesh tapes will NOT go through the taper.
The TapeTech Automatic Tapers (07TT, 04TT and 05TT) and the T05CF Bazooka Continuous Flow Taper both accept 250’ and 500’ (76.2 m and 152.4 m) paper and fiber tape rolls that measure 2 1/16” to 2 1/8” (52.39 mm to 53.96 mm) wide. Fiberglass screen or mesh adhesive tape will not work in the Automatic Tapers or the Bazooka Continuous Flow Tapers.
The Gooser Needle (the small needle that advances the tape) is attached to a white plastic tube called the Gooser Guide( part #054111F). If the Gooser Guide is getting stuck at the top of the Tape Guide, this area probably needs to be lubricated. Make sure to keep this area clean and free of dried joint compound and use Ames Bazooka Oil to keep the moving parts lubricated. Smooth operation of the Gooser Guide piece will ensure easy cutting and advancement of the tape. View the Schematic Drawings for the Automatic Tapers
While everyone has their own preference in the order that they tape a room, most automatic tool users will tape all the drywall butt joints (where two non-tapered edges of drywall meet) on the walls and ceilings first as they move around the job. These butt joints are wiped down with a taping knife and pan to press the tape into the joint compound and remove the excess mud. After the butt joints are taped and wiped down, all the flat joints (where two tapered edges of drywall meet) on the walls and ceilings are taped. Like the butt joints, the flat joints are wiped down with a taping knife and pan to press the tape into the joint compound and remove the excess mud. The final step is to tape the internal corners with the Automatic Taper, immediately followed by using the Corner Roller and Corner Finisher to produce a machine finished corner that is already embedded on both sides.
There are many commercially available lubricant products on the market. Most are designed for specific uses. Our experience is that many lubricants can cause some of the rubber parts used in ATF tools to swell, making the tools operate less effectively. We recommend using Ames Bazooka Oil when lubricating your TapeTech Automatic Taping and Finishing Tools.
