Drywall materials include different types of sheetrock, tools for special drywall techniques and drywall texture brushes. If you're planning a drywall project, you must be able to tell the difference between basic sheetrock and blue board.Types of SheetrockDrywall, or sheetrock, comes in several different varieties, each one intended for different uses or drywall techniques. The most common type of sheetrock is 1/2-inch drywall, which is available in sheets of different sizes.All drywall is fire resistant to some degree, as it has some water content. For walls next to fire hazards, such as attached garages, a slightly thicker 5/8-inch sheetrock can be purchased.Other specialized types of sheetrock include:Green board: Green board is a type of drywall with a green paper backing that provides better waterprotection. Water and moisture damage normal drywall materials. Green board is used around toilets and sinks where some splashing occurs. Tubs and shower walls require even more water resistance. For these locations,100 percent waterproof sheetrock is recommended.Impact resistant drywall: This is a strongervariety of sheetrock that has thicker paper and fiber strands mixed intothe gypsum interior to provide protection from damage.Quiet rock: Also called "sound board" quiet rock has "viscoelastic polymers" mixed into the gypsum that convert sound waves into heat energy, increasing the sheetrock's ability to absorb sound.Type X or type C: These drywall materials are available for walls that need even more fire resistance.Type X drywall provides a fire resistance rating in excess of 20 minutes.Materials for Specialized Drywall TechniquesSome drywall is designed for specific drywall techniques. Blue board, for instance, is a type of sheetrock designed for use with veneer plaster. One side of the blue board is backed with a special texture that improves the plaster's ability to stick to the drywall.Flexible drywall is a 1/4-inch thick sheetrock used for drywall techniques around tight curves and arches. When wet, flexible drywall can be shaped to fit unusually shaped walls.Tools for Drywall TechniquesBefore you begin any drywall project, make sure you have all the necessary materials. Additional drywall materials you may need include:Drywall compound: The compound is mixed into a thin "mud" and used to cover joints between drywall sections.Drywall corners: These are thin L-shaped metal strips designed to link two sheets of drywall at a corner and protect the drywall edges.Drywall tape: Despite its name, drywall tape is non-adhesive. The tape is a paper or plastic mesh thatsticks to a thin layer of compound and acts as an anchor for additionalcoats of compound.Drywall texture tools: These include paint rollers and special drywall texture brushes. Simple tools such as putty knives and even your own hands can also be used to create drywall texture finishes.Need More Help?If you need professional help with your project, LendingTree Home Pros can help.The good news is that LendingTree Home Pros maintains a directory of home service professionals and can match you with a home pro in your area.
