The task of hanging drywall is made simpler by a variety of tools. A drywall flat box is one of the less popular choices.
What exactly is a drywall flat box, then?

Simple drywall equipment called flat boxes make it easier for installers to swiftly and uniformly apply mud to the wall. The boxes have a long handle with a brake, are filled with joint compound, may be adjusted for thickness, and come with the boxes.

A drywaller applies drywall mud by running the flat box over the gap they are covering.
Heres what else you should know.
HOW ARE DRYWALL FLAT BOXES USED? FM

Drywall joint compound is kept in a box on wheels called a “flat box.” To let mud flow through the slots, you must release a brake lever on the handle.

As the drywall mud is applied to the wall, a plate applies pressure to it to smooth it out.
Using a drywall flat box is as follows:

Put mud in your container. Place the blade and box wheels flat at one side of the joint for horizontal joints. Roll the flat box from one end of the joint to the other after releasing the brake lever, applying uniform, steady pressure. Start at the bottom and run the flat box halfway up the wall for vertical joints. After that, raise the box to the joint’s top and lower it while continuing where you left off in the center. Even though drywall flat boxes can hasten drywall finishing, you must experiment with the setup to achieve the ideal flow. In order to get even coverage, it could also take some practice.

Additionally, automatic taping devices that pair flat boxes with automatic tapers are available. These, however, are typically more expensive.
DO DRYWALL FLAT BOXES MAKE SENSE? It depends on your needs as to whether purchasing a drywall flat box is worthwhile.

Unless you’re doing a repair job or a small room, probably not. A flat box, however, can save you a lot of work if you’re working on a big project or need to reach high places.

They are perfect for tall walls and ceilings since drywall flat boxes have handles that may occasionally be extended. Additionally, they have a learning curve even though they might aid in achieving smooth and equal coverage.

Therefore, purchasing one is probably not worthwhile unless you’re working on a large project.

LAST THOUGHTS Simple finishing tools called dry wall flat boxes enable drywallers to apply mud more quickly. For professionals and do-it-yourselfers working on big jobs, they’re fantastic.

Nevertheless, despite how fantastic they are, automatic drywall tools have a learning curve and aren’t required for modest drywall applications.
