Gypsum
Drywall tape is a paper or fiberglass material used to cover seams between drywall panels, while mesh is a self-adhesive tape made of fiberglass. Mesh tape is generally easier to work with and more suitable for repairing drywall because it is self-adhesive and less likely to bubble or blister.
Drywall
Drywall, also known as gypsum board or plasterboard, is a home-building material made primarily from the mineral gypsum. Gypsum is processed and compressed between two sheets of paper to create drywall panels commonly used for interior walls and ceilings in buildings.
Drywall is really actually made up of gypsum board, which is also called plaster board. The gypsum paper is smashed between two thick sheets of paper.
The best drywall gap filler to use for filling gaps between drywall sheets is joint compound.
YES, drywall is very porous material. If left outside, even covered, in damp conditions it will gain nearly 50 % of it's weight in moisture.
Between the sheets of drywall can be insulation or just hollow.
Yes. 'SheetRock' is a particular brand name for gypsum board. I believe 'Drywall is, too.
Joint compound and spackle are both used for repairing and finishing drywall, but they have some key differences. Joint compound is a thicker material that is used for taping and finishing seams between drywall panels. Spackle, on the other hand, is a lightweight material that is used for filling in small holes and cracks in drywall. Overall, joint compound is better for larger repairs and finishing, while spackle is better for smaller touch-ups.
Drywall is typically cheaper than paneling, but paneling can vary in price depending on the material. Drywall is easier to install than paneling, which requires more precision and skill. In terms of durability, drywall is more prone to damage from moisture and impact compared to paneling, which is generally more resistant.
Plaster is a traditional building material made of gypsum, sand, and water, while drywall is made of gypsum sandwiched between layers of paper. Plaster is applied wet and requires skilled labor for installation, while drywall is easier to install and can be done by DIYers. Plaster is more durable and can last for decades, while drywall is more prone to damage but can be easily repaired.
Calcium sulphate dihydrate is the primary material in drywall.
