Product Overview

Mid-Flex 300, a laminated composite corner tape from Strait-Flex, beautifully finishes outside corners, off angles, and vaulted ceilings. Mid-Flex 300 is also a great choice when replacing damaged metal corner bead. This 3 in. tape features a pre-finished surface with a PUR-laminated nose ensuring perfect corners without paper fuzz-up during finishing and sanding. The tape's outer edge features a diamond punch pattern for a superior bond, faster drying, with no rippling or blistering. To apply, measure and cut to length, then fold in half at center crease with print side facing out. For repairing damaged corner bead, tap the damaged area of the corner bead to be recessed below the corner's edge. Apply all-purpose compound to corner. Press Mid-Flex 300 into the wet compound, adjust to create a straight line, and wipe down with a taping knife using additional pressure to the outer edge of the tape. Immediately apply a light skim coat to the perforated edges and let dry. Apply final coat, let dry and sand.

Is the "3 in. x 100 ft. Mid-Flex 300 Laminated Drywall Corner Tape MF-100" only for outside corners? If so, is there something equivalent for inside corners? (I need to tape over existing inside 2" corner paper tape that has split, and pulled loose, pulling the sheetrock facing with it.)
Asked by: PHL3
The MF-100 is for both inside and outside corners. It will work fine for the application you described.

3 in. x 100 ft. Mid-Flex 300 Laminated Drywall Joint Corner Tape MF-100S is rated 4.7 out of 5 by 3.
Rated 4 out of 5 by from Does the job bridging gaps and providing a constant corner... Used this on a 100+ year old bldg. w/ cathedral clgs. and irregular framing. Despite lots of shimming the new sheetrock was not perfect along the hips which had 2" deflection over a 12 ft. span. This tape is sturdy and the additonal 1" width over paper is excellent. It is a bit thick at the bend but nicely tapered at the edge. You will use a bit of mud to make a good transition. End result is a a straight and sharp corner.

Rated 5 out of 5 by from Great product for inside corners that are not 90° I have several rooms in my house that do not have typical corners. Each year I get cracks in these corners due to the house settling. So this year I decided to do something about it. Instead of fixing it with the standard paper tape or the standard mesh tape, I searched for something that would last longer. That's when I found the Mid-Flex corner tape. It MUCH MUCH stronger than anything else I have found. It worked great on my 120°corners. It will work on any angle corner. It gives a very crisp straight line from top to bottom. I would highly recommend this for any corner that is not standard. Additionally, I had to call the manufacturer with a technical question. The person I spoke with was extremely knowledgeable.

Rated 5 out of 5 by from Perfect for odd angled joints So much easier to use than regular tape for angled joints. Holds the angle firmly.
