Use of Drywall Compound
Drywall compound is a mix of gypsum dust, water and other ingredients that form a white powder that is used to fill the joints between drywall walls and ceilings. The material is used with fiber or paper joint tape to form a seamless base for paint. If you want to save money on paint, you should buy a cheaper brand. Its price is comparatively low compared to other drywall repair materials.
There are many types of drywall compound. You can choose the type that meets your needs best. Some types are for joints, while others are for inside corners. To create the strongest seams, make sure to buy the right type for the project. Drywall compound can be divided into two general categories: setting compound and drying compound. Setting compound is the type that hardens through a chemical reaction, while drying compound is premixed and is dry by air.
The best way to repair drywall joints is to use topping compound, which has a low shrinkage and is highly workable. Most topping compound is sold as a dry powder that needs to be mixed with water. This allows you to use only the exact amount of product you need. Some of them are pre-mixed so you can easily mix them yourself. A thin layer of joint compound is applied at the seam, followed by the paper tape. After the compound has dried, you can sand and finish the wall.
Quickset compound is another option. It sets quickly and requires less mixing, while others require a long time. This type of compound is also available in different setting times, from about 20 minutes to 90 minutes. A faster drying time allows you less time to work with the mud, while a longer drying time makes it more difficult to handle. Both types can be sanded and painted, depending on the product you choose. This is the easiest type of drywall compound to use for your project.
