The three most common types of plaster used in construction and design are gypsum, lime, and cement.
Plasters are primarily categorized by their base binders: gypsum, lime, cement, or clay. Choosing the right type depends on the environment (interior vs. exterior), the desired aesthetic finish, and the building's age and moisture-control requirements.
Gypsum plaster is one of the most common types of plaster used in the interior of homes. It's often used in conjunction with plasterboard, but can also be used over existing plaster. "Gypsum is often the go-to plastering option when building, renovating or extending a home.
Gypsum plaster. Gypsum plaster, also known as plaster of Paris, is a white powder consisting of calcium sulfate hemihydrate. The natural form of the compound is the mineral bassanite. Although it is created out of gypsum, the powder is not itself gypsum, which is calcium sulfate dihydrate rather than hemihydrate.
Cement plastering is the most common plaster type used in India. It is made using cement, sand, and water. This plastering method provides strong and durable surfaces suitable for both internal and external walls. It is widely used because it offers good resistance to weather and moisture.
Bonding plaster is easy to mold into the desired shape and easy to apply to any surface. Once applied, it dries quickly and can be painted over. Any liquid that spills into the bonding plaster will not affect the plaster.
Silicone and Glass: Plaster does not naturally adhere well to silicone or glass surfaces.
Americans typically call plasters Band-Aids.
Level 4 is the generally accepted level of finish for domestic construction. Joints are to follow a three coat system, consisting of; a tape coat plus two subsequent coats applied over the tape coat and fastener heads. All joint compounds should be sanded to a smooth finish free of tool marks and ridges.
Decorative plaster, also called 'plasterwork' or 'carved plaster', is a centuries-old technique in which a durable plaster is used to sculpt decorative elements directly onto an interior or exterior wall or surface.
Natural plasters can be classified by their binder, with the three basic types being earthen (clay rich soil), lime, and gypsum.
Type II dental gypsum or dental plaster contains β-hemihydrate particles and is used as a study model material, a set-up material for the working model on articulators, and dental laboratory material.
Polycell Plaster Repair is ideal for repairing large areas of damaged plaster. The specially formulated powder is much easier to apply and smooth out than ordinary plaster. It gives a smooth,white, 'ready to decorate' finish to all masonry surfaces and will not slump, shrink or crack.
Homes built before 1919 traditionally used lime plaster as the finishing material, though its usage could have extended until the 1950s when plasterboard and gypsum became more prevalent.
A Level 3 qualification in Plastering, specifically the Level 3 NVQ, is an advanced, work-based qualification designed for experienced plasterers who want to formalise their skills, and progress within the construction industry.
The most common types of plaster used on walls are Gypsum plaster for modern interiors, Lime plaster for historic or "breathing" properties, and Cement plaster for durable, moisture-resistant areas.
Level 5 plastering (or drywall finishing) is the highest industry standard for achieving a flawless surface. It involves applying a very thin skim coat of joint compound over the entire surface of the board, eliminating all texture differences between the drywall paper and the mud.
Plasters are primarily categorized by their base binders: gypsum, lime, cement, or clay. Choosing the right type depends on the environment (interior vs. exterior), the desired aesthetic finish, and the building's age and moisture-control requirements.
What is the standard thickness of plastering? The standard thickness varies: for internal walls, it's generally 10-15 mm, while for external walls, it's 15-25 mm.
British people call band-aids plasters. Sometimes, they might refer to them specifically as sticky plasters or by the brand name Elastoplast.
Synonyms for "plaster" vary depending on its context.
In slang, "plastered" means extremely drunk. It is an informal adjective used to describe someone who has consumed so much alcohol they are heavily intoxicated, often to the point of impaired coordination, blacking out, or "feeling no pain".
Anti-Crack Plaster is a flexible interior and exterior skimcoat plaster which reduces the risk of cracking on drywall and other substrates and considerably improves the impact resistance and durability of all constructions.
Signs of infection: If you see signs of infection like increased redness, swelling, or pus, take off the plaster and consult a healthcare professional. Learn more about identifying infected wounds here.
Plaster is rarely used in modern construction primarily because drywall (gypsum board) is faster, significantly cheaper, and easier to install. While plaster is highly durable and offers better soundproofing and fire resistance, traditional multi-coat plastering requires highly skilled labor and lengthy drying times, making it inefficient for modern housing demands.
