  5. Comparing Vinyl Corner Bead Installation Methods

    Over the last 50-plus years, Trim-Tex’s vinyl corner beads have been known for just one main installation technique: you hit them with spray adhesive and you staple them. But that’s not the end of our story anymore. These days, there’s a few different vinyl corner bead installation methods to choose from, depending on the solution you’re using and the way you want to work. Are you all about a speedy install, or do you prioritize strong corners above all? Whatever way you finish, we got a solution to match it.

    There are three tactics to consider when browsing through our collection of corner beads: spray-and-staple standard vinyl, Mud Set and Fast Edge®. These three techniques are not interchangeable, so be sure to consult product instructions before you begin installation.


    The tried-and-true technique for outfitting your corners with toughened vinyl, just because this method is conventional doesn’t mean it’s not highly effective. Spray-and-staple standard corner beads are a mainstay of drywall finishing for a good reason — they’re highly effective, stand the test of time and don’t have much of a learning curve.

    The advantage of using 847 Spray Adhesive is that, by adhering the surface of the bead directly to the drywall, you minimize slipping during expansion, versus using staples alone. Unlike many all-purpose spray adhesives on the market, Trim-Tex’s 847 Spray Adhesive is designed specifically for corner bead. The adhesive is a web spray, which improves adhesion over standard mist sprays, and is colored to help easily identify it.

    Combining this spray with staples along its mud leg gives the corner bead a strong bond to the drywall that has been proven to last. If you want an installation method that’s been time-tested and used by countless finishers across the world, look no further.


    The spray-and-staple technique uses a spray adhesive — such as the high-tack, pressure-sensitive Trim-Tex 847 discussed above — to attach the bead before stapling it in place. Spray continuously from a distance of 6 to 10 inches, being sure to keep the spray moving to avoid buildup on the drywall or bead surface. It doesn’t take much spray to attach the bead, and too much can mean a longer wait time for it to get tacky. (This quick-tip video demonstrates good technique with the spray can.)

    Apply 847 to the drywall, then to the bead before positioning the bead into place. Press the corner bead in place using a pressuring tool or the handle of your taping knife and finish by stapling every six to eight inches — Trim-Tex recommends using half-inch staples.


    Mud Set Beads are drywall corner beads made from high-impact, rigid vinyl, featuring Trim-Tex’s patented Mud Lock Technology.

    Essentially, these Mud Locks are a series of hooks along the bead’s mud legs that grip into the joint compound to latch the bead firmly onto the surface, almost like a bunch of super-powered hook-and-loop straps. Meanwhile, excess compound is allowed to flow through perforated mud holes (which are noticeably smaller than in standard vinyl beads for better adhesion). All of this is what gives Mud Set Bead the strongest-possible bond to the drywall of any corner bead on the market. The strength of the bond between the mud legs, drywall compound and wall, combined with the elasticity properties of rigid vinyl, allow the bead to withstand a high degree of impact.

    This strength isn’t just for show — it saves time and money by reducing building maintenance costs, as well as callbacks for the finisher. When a traditional corner gets dented, rusts or forms mold, it needs to be replaced, which is a time-consuming process. Mud Set Beads are strong enough to withstand daily wear-and-tear as well as more intense impact.

    If you’ve installed a metal corner bead, a good whack will dent and deform its nose — this kind of damage is irreparable, and you’d have to replace any affected section, or rip the whole thing out and start again. That same impact to a Mud Set Bead-protected corner, however, won’t have any effect on its nose. If any damage does occur, it’s almost always going to be the drywall mud that fails, which you can fix with a quick patch.


    To install these Mud Set Beads, run them through a 4-in-1 Mud Hopper, or use a knife or compound applicator tube to apply the mud onto the corner directly. The hopper installs Mud Set 90 Degree Bead, Mud Set Bullnose and Splayed Beads with ease to help minimize jobsite delays. With mud applied, press the bead into place with a roller tool or the end of a taping knife.

    Excess mud will squeeze through the perforations, which essentially levels out the bead from sitting too high on the corner; it also minimizes the amount of mud needed for the setting coat to form an incomparably strong bond between the bead and the drywall. Check for squareness of the bead, adjusting as needed. Then just wipe the excess mud clean and go ahead and apply your fill coat — the Mud Set method saves time and labor by allowing the fill coat to be applied that same day.


    The newest of our various vinyl corner bead installation methods, you’ll notice the difference with Fast Edge immediately — there’s no mud holes and no mud bump. Instead, Fast Edge sports a vinyl core, covered in laminated paper. It’s perfect for finishers looking to up their games from paper-covered metal corner beads, or those just looking to finish the job faster while using less materials.

    In fact, Fast Edge isn’t just the quickest installation method of these three; it’s the quickest corner-bead solution you’ll find anywhere, in addition to saving you more mud than any other corner bead out there. How do we know? We put it to the test! You can check out the results of that head-to-head matchup here.

    Fast Edge also utilizes the Mud Lock Technology we previously discussed for extra-strength adhesion, but with no mud holes, excess compound gets pushed out the back of the bead. The lack of a mud bump here is key to reducing the amount of mud used overall to install a Fast Edge corner bead, and the vinyl core means this is a long-lasting, super-durable solution for protecting your corners.


    Since it also features Mud Lock Technology, the process for installing Fast Edge is quite similar to that of Mud Set Beads — no staples or sprays required.

    Run a length of Fast Edge through a hopper, or use a knife or compound applicator tube to apply mud directly on the drywall. Stick the bead in place on the corner, making sure your lines are straight, then we’d suggest you use a Pro Series Quad Roller to apply pressure evenly. Use a taping knife to whip down the excess mud that has been squeezed through the back of the bead’s mud legs.

    You can then layer on your fill coat of mud right away and, once that dries, your finish coat. Where standard vinyl will require around three coats of mud to finish, you’re already prepared to move on to your next project with the Fast Edge installation method. We named it Fast Edge for a good reason!

    When it comes to comparing vinyl corner bead installation methods, we’ll let you be the judge — there’s no wrong answers here! When you choose vinyl, you’re choosing higher-quality materials, choosing impact resistance, choosing no rust and no mold.

    The choice you make in installation method from there — between spray-and-staples standard vinyl, Mud Set Beads and Fast Edge — entirely depends on what’s most important to you, the finisher. Do you want the tried-and-true method, the strongest or the fastest?

    Stitches, Staples, or Skin Glue (Liquid Stitches): Which Do You Need?

    If you or your child has a minor cut or scrape at home, you should clean the wound and stick a bandage over it.

    But if you have a more severe gash, cut, or break in the skin, a doctor might use other options to close your wound. These might include stitches, staples, glue, or zippers. The type of material and technique your doctor uses will depend on many things, like what type of injury you have, your age and health, your doctor’s experience and preference, and what materials are available.

    Adhesive Tape

    Doctors use sticky strips of tape (such as Steri-Strips) to pull together the edges of minor skin wounds. Skin tape costs less than other types of materials used to close wounds. But tape can lose its stickiness over time, especially if it gets wet. If it gets loose, the wound can break open.

    Your doctor may use adhesive tape if you have a minor cut, laceration, or incision (low-tension wound). They might also use it during surgery if you have buried or absorbable skin sutures (stitches).

    The strips usually fall off by themselves in about 10 days.

    Sutures (Stitches)

    This is the most common technique for closing skin wounds. A doctor uses a piece of surgical thread called a suture to sew (or stitch) two ends of skin together. Surgeons once used animal tendons, horsehair, pieces of plants, or human hair to create sutures. Today, they’re made from natural or manmade materials like plastic, nylon, or silk.

    Sutures may be permanent or absorbable (they dissolve in the body). Which type your doctor chooses depends on many things, including the type of incision and your risk of infection.

    Your doctor may use permanent sutures for:

    • Wounds that might take a long time to heal
    • Closing surgical incisions, including those made for drainage tubes
    • Tying off blood vessels or parts of the bowel
    • Wounds involving connective tissue (fascia), muscles, or blood vessels

    They might choose absorbable sutures for wounds that involve:

    • Lower layers of skin
    • Muscle and connective tissue
    • Lining inside the mouth
    • Areas with blood vessels close to the surface of the skin

    Doctors sometimes use fast-absorbing sutures for skin grafts. That’s when your doctor covers lost or damaged skin with a patch of healthy skin.

    Glue (Tissue Adhesive)

    Doctors use surgical glue — also called “tissue adhesive” or “liquid stitches”– to close both major and minor wounds, such as lacerations, incisions made during laparoscopic surgery, and wounds on the face or in the groin.

    Benefits of surgical glue include:

    • Lower rates of infection
    • Less time in the operating room
    • Less scarring
    • No needle sticks or stitches (child friendly)
    • Quicker return to work and other activities, like sports
    • No stitches to remove

    Surgical glue costs more than sutures. Some people are allergic to it. The glue can’t be used if you have an increased risk for slow wound healing (this occurs with diabetes and other health conditions).

    Application of the glue requires a precise technique. Ask your doctor about their experience using this wound-closure material.


    Doctors can use a skin stapler to quickly close a long skin wound or cut in a hard-to-reach area. Staples may dissolve in the body — meaning they’re absorbable — or may be external and need to be removed by your doctor.

    There are a number of benefits to using medical staples. They allow your doctor to quickly close your wound with minimal damage. They’re easier to remove than stitches, and you spend less time under anesthesia.

    With absorbable staples, you also have a lower risk of infection. Wounds tend to heal better, and you have fewer issues with scarring.


    This is an alternative to conventional sutures. It’s often used for wounds that need to be monitored by your doctor on a regular basis. It combines a zipper with two strips of adhesive, which are placed on either side of the wound and trimmed to size after surgery. When the zipper closes, it pulls the edges of the skin together. Studies show it’s painless to remove, so it could be a good option for kids. The zipper can’t be used in obese patients and those with wounds that curve more than 20 degrees.
