A majority of homes in the United States built after the 1940s have drywall covering in their interior walls. Walls were made of plaster before this period, but since it took up a great deal of money and time builders started using drywall instead.

Though drywall installation still needs great amount of skill, the effort needed is not on par with that of a plaster wall. Texture coating of ceilings and walls is done to mask the imperfections expertly. However, the nails, seams or screws cannot be covered in this manner. Proper finishing is needed to accomplish this. A good finish will give the texturing more attractiveness.

Main considerations in finishing

Proper techniques in drywall finishingThe finishing of a drywall includes covering the screws, seams and nails with finishing compound also called as drywall mud and joint taping. The main objective in finishing is to produce a smooth surface free of blemishes with no visible seams or fasteners in the walls, making them appear like a single solid smooth sheet.

The process

The finishing involves a multiple coat application process. The initial coat involves filling nail hole and screw holes and tape application. There are two tape types namely, fiberglass and paper. The fiberglass is in the form of a screen. The sticky tape is laid on the drywall seams and adhered to the wall. The paper tape is adhered to the wall using a finishing compound. Unbroken tape runs give a more complete look. To smooth out the layer, finishing knife is used.

Once the first coat is over, sanding is done and another coat is given. Vibratory sander or pole sander is used. For better effectiveness, the drywall sand screen attached to electric or pole sander is used to prevent dust from clogging, as happens with sandpaper. The second coat is finished with tapering or feathered edges.

Over the second coat, a final or third coat is given with feathered edges. This is later sanded after drying and once a smooth surface is obtained, texturing is done.

Difficulties faced in finishing

Some of the frequent issues that are experienced with finishing include lumpy drywall compound, tape bubbles and nail pops. A taping compound that is slow drying, protruding screen heads and crushed drywall edges are other common difficulties faced with installation of drywall. Minor defects like ridges, dips or scuffmarks will become visible, only when you start the primer application.

Butt joints taping

Joint taping of the butt joints should be done initially with a thin initial coat. This should be followed by a two to three coats, so the ridge is hidden well. Each coat should be smooth and flat, and be levelled out at both sides of the joint. A butt joint required patient application of coating.
