Many buildings have drywall as the interior walls.
Residential and commercial builders need materials to finish the interior walls of construction projects. Rather than finishing walls with plaster, builders opt for drywall since it costs less and is easier to install. However, some builders select blue board when finishing the interior walls of a building. Unlike drywall, blue board requires a coat of plaster, which takes several days to dry completely.
About Drywall
Builders started using drywall in the 1900s. It covers the interior of walls and people use it as a substitute for plaster since it offers a seamless installation. Drywall is resistant to fire and deters noise. Other names for drywall is sheetrock, gypsum or plasterboard. Manufacturers grind gypsum ore into thin powder and face the front and back surface with specialized paper to make drywall.
Characteristics
Unlike traditional drywall, blue board has a blue face, which is derived from the paper on its surface. Manufacturers treat the specialty paper to bond to a thin coat of formulated plaster. With blue board, an application of tape and plaster treatment is applied to the joints, and then two thin coats of plaster are applied to the surface of the blue board. With drywall, numerous coats of joint compound along the seams in the middle of the boards is applied.
About Blue Board
Blue board insulates houses and buildings. It is sometimes referred to as extruded polystyrene insulation board. It works well in bathrooms or places with a lot of moisture. Once the plaster dries, the plaster creates a waterproof seal in the middle of the blue board and interior space. Additionally, this type of board helps reduce noise and offers low emissions.
Blue Board Installation
It is possible that a novice can install drywall with practice. However, it is best to hire a professional to install blue board. It is sometimes difficult to make the surface of blue board smooth and if you make a mistake in the process, removing the plaster may destroy the blue board.
Similarities
Home improvement stores carry blue board and drywall in 4-foot-wide boards in various lengths including 8, 12 and 16 feet. Manufacturers make both materials from gypsum. Construction workers can cut blue board and drywall material with a knife. In addition, you can attach blue board and drywall with screws to steel and wood wall studs.
