Answer: 
I would say no, the area where the corner should be is very rigid and may flex and pop the mud free around it causing more rework in the future

Answer: 
It will. It is a little thicker than the Butt-Tape so you might have fan your mud out a little more to cover up the joint.

Answer: 
Laminate composite. BY FAR. I have been doing drywall for over 30 years, and this tape is the best I have ever used. The "original" Straight-Flex is the best for sanding, but it is a little thicker than their other products. I use your basic fiberglass mesh tape on factory joints, and composite tape on butt joints and inside corners.

Given a choice, The Mesh! In application, they are pretty much identical... But the paper and paper composites are prone to fraying and pucker. The mesh, if mud application is scraped too hard, will have ripples, but they are something you can cover with a second coat of mud after the first coat has dried.

Given a choice, The Mesh! In application, they are pretty much identical... But the paper and paper composites are prone to fraying and pucker. The mesh, if mud application is scraped too hard, will have ripples, but they are something you can cover with a second coat of mud after the first coat has dried. With paper, you can get pucker years later. Either you live with it or you cut the pucker out with a utility knife and try to mud the hole. If you choose the paper, I recommend you make sure it is DAMP before you place it on the mud. During my first foray into mud-n-taping, we used paper. Someone told me to make sure it was damp before it was applied. I didn't do that and had to make many repairs to the puckers and bubbles that appeared later. The next time I used paper, I had a bucket of room temp water that I dipped the tape into. I would then pinch it with my fingers and pull it through to remove the lion's share of the water. This method worked much better, but years later, bubbles and puckers appeared again. Not as many, but still. We haven't really had any problems with the mesh! Your choice and good luck Read Less

Answer: 
Paper laminated composite is a better overall product. The memory-free hinge design allows for ease of installation, straighter corners, and perfect angles. The PUR-laminated nose ensures perfect corners without paper fuzz-up during finishing and sanding.

Answer: 
I wouldn't recommend it for 135 degree corners. I would use either Strait-Flex Original or Strait-Flex Medium. Those are a much better option then the Perfect 90. You can find them at most Home Depots.

Rated 4.5 out of 5 by 28 reviewers.
Rated 4.0 out of 5.0 by Great corners They make great corners, but outside corners do not come out as well, and when painted, it tends to bubble on the ceiling side of the corner. August 23, 2016
Rated 5.0 out of 5.0 by DIY Perfectness Ok. First Time.. EVER.. decided to finish my workroom, stud out walls, soffit ladders, lay up sheetrock.. and now had LOTS of inside and outside corners to deal with. Paper tape works great on flats... and figured out metal corner beads for outside corners... but inside corners? Geesh.. THat was tough with paper tape - so I Found this product through Youtube videos that made inside corners A SNAP. No kidding. This stuff ROCKS and saved at least a few days worth of labor mudding paper. THANK YOU STRAIT FLEX for making this product. I also used the original product for outside corners in some places, but not as good as the metal beads. PERFECT 90 for inside corners.. EVERYTIME. Mudding, prime and paint was so easy. March 22, 2016
Rated 4.0 out of 5.0 by Good purchase Good product, the only thing lacking were better instructions. They are very vague, and somewhat hard to understand. The product does take a little more "mud" then you would think to hide the area you are supposed to mud. Overall a good product and I will buy it again as I continue to remodel my home. April 20, 2016
Rated 5.0 out of 5.0 by The stiffness definitely makes this easier to work with This isn't the cheapest, but it makes the job go faster. Once you crease the flat tape, it has surprising rigidity. March 21, 2016
Rated 2.0 out of 5.0 by Too expensive for the final result I agree that his is a good product and it's does create a very good high quality internal corner. Just very little value in paying $15 for 100' vs 2$ for 250' that works almost as well. Don't think you are going to purchase this product and become instantly great at corners...stay with the paper in my opinion. March 8, 2016
Rated 5.0 out of 5.0 by Perfect 90 Drywall Joint Tape - 100 times better then plain paper tape The inside corner tape made perfect corners with less drywall mud and less time to do March 1, 2016
Rated 4.0 out of 5.0 by work great, makes inside and outside corners easy makes inside and outside corners sharp and neat very easy February 23, 2016
Rated 5.0 out of 5.0 by Joint Tape Was easy to use. Wish it was sold in a shorterlength than 100 feet. Would purchase again. February 16, 2016
