En Facades World we believe that helping them know the advantages and disadvantages of plaster walls You can be a great boost for all our readers, since after this informative article they will know if they want to use them in their homes or not. So once again, as usual, we ask you to pay close attention to what comes next because right now we start!
Drywall to use in our interior or exterior design - Everything you need to know
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO4: 2H20). Gypsum is a chalk-like material and is very lightweight, and you will find it available in crystalline form in nature. Plaster walls can be a very good option or solution to implement in your home ... let's see.
Plaster, although it is a much older material than cement plaster and sand, has rarely been widely used in the construction industry. Today, gypsum has proven to be a miracle material that helps build interior due to its properties.
What is plaster wall plaster?
When dry powder mixes with water, it hardens. This material that can be applied to bricks, blocks, or concrete surfaces to form a smooth surface is called gypsum.
Previously, a 6mm layer of plaster was usually applied over the cement plaster to give it a smooth finish before painting. This is a two-stage process and involves various elements such as sand, cement, and water that must be mixed on site.
This process is slowly being replaced by a direct application of a single layer of plaster. For him gypsum plaster, the prepared powder is mixed with water and applied directly to the wall.
El plaster wall plaster It can be applied directly to any brick, solid or hollow block, AAC block, and gypsum board.
Plaster plaster thickness
It can be applied in the thickness 6-20 mm. The thickness of the lower layer of plaster is normally 11 mm for walls and 8 mm for the ceiling, while that of the finish layer is 2 mm.
It is recommended to apply a minimum thickness of gypsum plaster of 6 mm to avoid cracks. If more than 20mm thickness of plaster is required on a wall, then an initial layer of cement sand plaster is applied for a thickness of 8-12mm, then plaster is applied for the remaining thickness of not less than 6mm to achieve a smooth finish.
Advantages of gypsum plaster
Contractors and builders began to prefer plaster due to its superior finish and time-saving attributes.
- Ease of application- Plaster can be applied directly to the brick / block job. It is also very easy to apply and level.
- No shrinkage cracks: The gypsum reaction produces less heat compared to the reaction of cement with water. Therefore, there are fewer shrinkage cracks in the plaster compared to traditional cement plaster.
- Fast setting time: The plaster sets quickly (that is, within 25-30 minutes). Therefore, painting could begin 72 hours after the application of plaster.
- Does not require curing time: gypsum plaster does not need curing, saving water and time during construction.
- High productivity: reduces time considerably compared to conventional cement plaster.
- High performance: excellent high strength after drying, durable and light.
- Smooth finish: perfectly aligned, level, smooth walls and perfect right angle corners
- Fire resistant: the plaster is very resistant to fire.
- Low thermal conductivity: the plaster has low thermal conductivity. This saves electrical costs for heating and cooling rooms in a building.
- Decorative application: It can also be easily applied for decorative purposes and can be molded into different shapes.
Disadvantages of plaster walls
Gypsum cannot be used for exterior walls since they retain moisture. Also, gypsum plaster cannot be done in areas that are continuously humid, such as the bathroom, etc.
The plaster in plaster walls it is more expensive than traditional cement plaster (cement and sand) for the same thickness.
