What Are the Different Types of Mesh Drywall Tape?
There’s not a whole lot of variety available in this kind of product due to its nature, but there are a number of different tapes available for drywall usage around and a quick comparison definitely doesn’t hurt.
Paper tapes are commonly used and the oldest type of tape applied to the fine art of joints and seams. It is most often laid over the compound before another layer is applied over the top of it.
It’s useful for some applications, particularly inside corners, since it sits almost entirely flat with the wall. For the most part, marketing aside, it’s simply a slightly stronger masking tape for all intents and purposes.
What this means is that it’s easy to work with but doesn’t add strength to the wall and instead you’ll be relying on just the screws and compound to hold things together.
Improperly applied paper tape can have disastrous consequences as well, if you didn’t set it right it can peel up and tear off the mud. This isn’t just cosmetic, it can have disastrous consequences on your wall.
Self-adhesive tape can help you avoid the delaminating issue entirely, and if you opt to use paper tape first and find this to be a problem you’re probably better off switching.
Fiberglass tape on the other hand, acts something like rebar in concrete construction. It’s extremely strong, and the porous nature of the tape allows for a neat trick to occur when it’s laid down properly.
First you’ll lay setting compound under the tape, then over the tape and it will join to form a cohesive hole without much of a barrier. This makes it exceptionally strong.
Some people not that they have problems with cracking when using fiberglass tape, and it certainly can occur since the mesh is elastic. This is generally due to improper application of setting compound, you’ll need to use setting compound with fiberglass tape since it doesn’t shrink as it dries.
Many professionals aren’t fond of self-adhesive fiberglass, but if you’re careful and precise in your application, it can make a huge difference in the final strength of the wall.
