Inside Corner Bead Vs Paper Tape

When finishing drywall, there are so many different products for finishing various joints and corners that it can be challenging to know which products to use and when. For example, inside corner bead vs. paper tape &#; which product is better for finishing your inside corners?

Please visit our website for more information on this topic.

When it comes to inside corner bead or paper tape, it is essential to have all of the information in order to make an informed decision and choose the right product for your project.

Paper Tape

Paper tape is the more traditional option in the battle of inside corner bead vs. paper tape.

Paper tape has been used by drywall professionals and DIYers alike for decades, but is there a better option on the market? While there are numerous positives to using paper tape, there are also some considerable downsides.

Pros

Paper tape is the most common product used to finish the inside corners of drywall and has been the top choice of pros for decades for several reasons:

Speed

One of the biggest reasons pros continually reach for paper tape is the speed of installation.

Simply lay down a bed of joint compound, then embed your paper tape into the bed with a clean swipe of your taping knife; that&#;s all it takes.

Cost

Paper tape can be bought in large rolls at low prices, which makes it a cost-effective method of finishing inside corners.

Cons

Although there are a lot of upsides to using paper tape, there are also some downsides:

Bubbles

While experienced and professional tapers can apply paper tape quickly and easily, novice tapers can find the installation troublesome.

Embedding your paper tape into a bed of mud on your inside corner can be a piece of cake for professionals, but their skills have been built up with experience over time.

It can be frustratingly difficult for amateurs to embed their tape in the correct amount of joint compound. Remove too little compound from your tape coat, and you will be left with a nightmarish buildup in your corner. Remove too much, and your tape will not adhere correctly and will leave tape that bubbles up through your finishing coats.

Peeling

Peeling is another common outcome that can plague inexperienced tapers. Peeling is most often a symptom of applying your tape coat too tight &#; this can prevent your tape from adhering correctly and result in the edges of your tape peeling up.

Inside Corner Bead

Outside corner beads

Whether on a wall or on a soffit, outside corners must be covered with corner bead. The material protects the surface and has a slightly raised beaded edge, which keeps the corner straight and acts as a screed while taping.

It wasn&#;t too long ago that square-edged metal corner bead was the most commonly used corner bead, and it may still be today, but the other options really are worth looking into. Today, you have your choice of metal, vinyl, plastic covered with paper, or metal covered with paper. Some types are available in 100-ft. rolls. Bullnose beads are also available in a variety of sizes and have become very popular because they offer an elegant look and are just as easy to install as regular bead.

 

Archway bead For years, I used metal corner bead to finish the edges of archways. The only way to install it was to snip the bead at 1-in. intervals and push each piece into place along the curve of the arch. This method worked, but it cannot be compared to the simplicity and quality you get with new products designed specifically for archways. There are three basic types of flexible corner bead made for arches:

• Flexible wire bead has a plastic beaded edge and is nailed in place.
• Vinyl bead has a pre-snipped edge that is glued and stapled in place.
• Composite bead has a PVC core and a paper surface and is embedded in joint compound.

The PVC material comes in rolls up to 100 ft. long and is now available in stick form with a wire reinforced edge. The wire and vinyl beads come in lengths of up to 10 ft. and the composite bead comes in lengths of up to 100 ft. Vinyl bullnose corner bead, which is flexible, is available to match the outside and inside corner bullnose beads. If you are using bullnose corner bead on your 90-degree corners, then you will most likely want bullnose on the archways. The vinyl bead companies make archway beads in all the bullnose radii. There are even bullnose beads made for off-angle inside and outside corners (135-degree corners only).

 

Inside corner beads

On most inside corners, I use paper tape embedded in joint compound, which is then covered with compound and feathered to a smooth edge. This method works great for inside corners that are around 90 degrees.

When I first saw a 90-degree inside corner bead I really couldn&#;t see why anybody would use it. I am a professional and I get great results with paper tape so I wouldn&#;t spend the money on a bead for a 90-degree inside corner. But after using the different types of bead I can see why they would be used:

• You don&#;t have to coat the very inside edge with compound. Therefore, both sides of the corner can be coated at once&#;as opposed to waiting for one edge to dry and then coating the other.
• When sanding you can sand the inside edge clean and straight, because you don&#;t have to leave any compound in the corner.
• All this adds up to a great-looking inside corner, especially for the less experienced taper.
• The end result is a very strong and straight inside corner.

 

Securing Corner Beads

Among many contractors, nailing or crimping a standard metal corner bead in place is gradually being replaced by beads that are attached using adhesive only. With these beads, the adhesive is simply sprayed onto the drywall along the entire length of the bead. All corner beads should be installed in one piece, unless the length of the corner exceeds the standard corner-bead lengths of 6 ft. 10 in., 8 ft., 9 ft., and 10 ft.

 

If an inside corner is much wider than 90 degrees, a specialized product is a must for achieving the straight lines that define these corners. Fortunately, there are a number of products that can handle these off angles. Some work on both inside and outside corners; others are more specialized and designed for application on specific-angle corners. For off-angle inside corners, there is even a product that has a rubber center groove, which flexes if the structure moves slightly, greatly reducing costly callbacks. Inside corner beads are also available in bullnose styles to match bullnose outside corners. These products cost more than regular paper tape and compound, but you easily make up the extra cost in time saved and improved quality.

Trim beads

Metal, plastic, and paper-covered metal J-trims are caps used to cover the edges of drywall panels. Typically, they are applied against a shower stall, a window jamb, or a brick wall; around an opening that is left untrimmed; or on the exposed end of a panel. J-trim is available in different thicknesses to fit different sizes of drywall. It can be installed before the panel is hung or after the panel is loosely attached. It is held in place by driving a nail or screw through the face of the drywall and through the longer back flange of the J-trim. Some types need to be finished with joint compound, whereas others do not require any finishing at all (see the drawing below).

 

An L-bead finishes the edges of drywall that butt up against something, such as a suspended ceiling, a window, or a paneled wall. The drywall is cut so that the short edge of the L-bead can be inserted between the drywall and the abutting material. The exposed edge of the bead is then finished with joint compound. Many of these L-beads have a removable strip that protects the abutting surface from compound and some can be left on to protect the surface from paint. Trim beads are available in lengths of up to 12 ft. long and for 1/2-in.- and 5/8-in.-thick drywall. I prefer L-beads over J-beads in most applications, as L-beads are easier to install&#;especially on longer runs&#;because they are attached after the drywall.

Expansion joints

Expansion joints, which are made of metal or vinyl, are installed between drywall panels. They are not covered with joint compound, as other typical drywall joints are, but they can be filled with a flexible caulk. Expansion joints are designed to compensate for the expansion and contraction of building materials and for the normal settling of a building, so that drywall seams don&#;t become cracked or ridged. They are used when there is a large expanse of ceiling or wall. On ceilings, they run from wall to wall; on walls, they run from ceiling to floor. In high stairway walls, they are installed from wall to wall.
