What is a joint compound?

A common compound is a product used to fill the gaps between plasterboard sheets and depression, which leave screws after installation or repair. It is also called "mud" because of its strong consistency, the pre -pressed articulated compound usually comes in buckets ranging from 1 liter to 5 gallons (about 0.9 to 3.7 liters). Larger dry packages are also available, but the user must form the mixture with water.

The typical installation of plasterboard requires more leaves, because most walls are larger than even the largest pieces of plasterboard. Careful planning in advance can minimize the number of pieces used on the wall and reduce the number of seams. If the seams and depression of the screws are not filled with joint compounds, the finished wall will not be smooth and will therefore be unsuitable for painting or hanging wallpaper.

For correct application of the joint compound to a new wall, compound, joint tape, joint click and sandpaper. Common tape comes in separate and plain varieties. Separate joint tape accelerates whyes, but either the species can provide good results. The joint tape is not necessary to fill the holes for screws, as the holes must be completely filled with mud for proper work.

6 If the Self-Sticking tape is used, the initial mud application is not required. Elving the tape on the wall with a knife recording pulls out all air bubbles and excess mud and leaves a smooth surface. When an ordinary joint tape and mud are used for this first step, the seams must dry for 24 hours to move to the next step, grind excess mud and tape to further smooth the seams. Grinding at this point is not necessary for self -shaving joint tape.

through the seams and tape should be applied a thin coat of the joint mixture is surrounded by plasterboard. The total width of this layer should be about 6 inches (15.24 cm). Once this layer dries, it is necessary to have a final grinding to completely smooth the surface of the plasterboard within the pthe river for painting or wallpaper.

The joint compound can also be used to repair small holes or depression in older walls. Small cracks and holes require only a small amount of mud, as they do holes from the installation screw. Larger holes or defects may require repair with a small piece of plasterboard and create seams that must be treated in the same way as the treatment of seams in the newly installed plasterboard.
