At the moment, the alternatives and methods used in construction are the most varied and it is really difficult to decide what is the best process for your work. Both gypsum and tread are used to fill imperfections and level masonry surfaces that remain in damp environments such as the living room, bedrooms and rooms other than the bathroom and kitchen.
How to put plaster on the wall: tips on how to do it
The application of the running mass and plaster is very similar, both can be done with a trowel or a steel spatula, two or three coats, so that the end is perfect.
Positive points and advantages of plaster
- No need for sealant application before use;
- Dries much faster than running dough;
- Can be applied directly to concrete;
- The application is fast, which saves time;
- Lower costs.
Negative points and disadvantages of plaster
- Because it is a porous material, the cost of painting increases because it uses more paint;
- The product should be mixed with water before application to form a paste;
- Cannot be used on exterior walls that are exposed to rain;
- Can’t be washed;
- It is less resistant.
Positive points and advantages of mass racing
- Since it is a material that has been formulated for painting, it uses less color.
- Comes ready to apply, doesn’t need preparation;
- It offers better sound insulation.
Negative points and disadvantages of mass racing
- You need to use Sealer before mass;
- Make sure the surfaces are coated with gypsum before applying.
It is difficult to say which one is the best. In our country, building culture still depends heavily on gypsum with the application of mass, this is the most common finish. In other countries, gypsum or drywall is found more often.
How to put plaster on the wall: required materials
To put plaster on the wall, you need the following materials:
- PVC and steel cutter;
- Spatula or spatula;
- 2m aluminum ruler;
- Aluminum angle;
- Plaster bags in sufficient quantity for the application of the surface.
How to pass plaster on the wall step by step
1. Surface preparation
In order for the plaster to be applied efficiently and quickly, the surface must be flat and without burrs. Ideally, the electrical part is already finished, also the hydraulic part, posts are attached to the masonry and the infrastructure for the air conditioning is already installed.
It is important to wait at least 30 days after lifting the walls and ceilings to apply the plaster coating, because during this time the mortar has already hardened and not deformed, the concrete has already settled and the plaster too.
Remove dirt, nails and objects that could damage the coating. Check if the walls are flat.
2. Mixture of plaster
The patch packs are usually sold in 40 kg bags in powder form. The gypsum powder must be mixed in water with a proportion of 36 to 40 liters of water per bag and must follow a certain order:
- Fill the Masseira with water and sprinkle the powder so that it fills the bale evenly.
- Let the dough stand for 8 to 10 minutes so that the powder dissolves.
- Then part of the paste should be mixed, with the rest resting in the Masseira.
- Let the mixture stand for another 3 to 5 minutes to induce the paste.
- Note the consistency of the paste, after this second waiting period it can already be applied to the walls.
- At the end of the application of this first part of the mixture, the rest, which has remained at rest, is ready for use without the need for mixing.
3. Surface application
Always start the application from top to bottom and protect the floor from dirt and dripping scabies that cover everything with canvas. Use angles to finish the corners and corners, they protect the corners.
Moisten the walls before applying the mass and on the ceiling, make the application with a PVC trowel in back and forth movements. Then start the application on the walls, always from top to bottom. Pay attention to the thickness, it should be between 1 and 3 mm.
The second layer should be applied immediately in the order transverse to the first layer and with the aluminum ruler you should remove the excess and check the thickness according to the given references.
Use the steel trowel to evenly level the surface, eliminate waves and flaws. Finally, apply the last layer to correct any errors and to achieve the desired final thickness. The final performance must be done with great care and humor until the surface is very smooth and regular.
With smooth plaster of plaster
In this technique, the applicator (or gossier) creates master lines and defines the height of the layers with taliscas. Taliscas are small pieces of ceramic in a rectangular format that are attached to the walls to limit the thickness of the mass.
The spaces delimited by the masts and taliscas are filled with the gypsum paste and the excess is removed with the aluminum ruler, as if you were going to pass a crossbar to level the mass. Finally, do a very careful job, similar to that described in the procedure for applying smooth plasters.
Plasterboard or drywall?
Another plaster that is commonly used in interior fittings and renovations is gypsum plaster, which is also known as a drywall. This finish comes in plasterboard on cardboard. It is practical, even easier to install, the aesthetic finish is great and has a great aesthetic variety.
It is very versatile, can be cut in curves, can hold nails and screws and is used to assemble panels, partitions, walls and lowered ceilings. It enables the installation of televisions, shelves and other objects on the surface and even other materials such as ceramics, glass inserts, wallpapers, fabrics, PVA ink and textures.
Reduction of work costs
The interior lining most used in construction remains the traditional slab and plaster, but it is a technique that, in addition to being very time consuming, increases the end cost of the work and wastes a lot of material.
Through a quick calculation, the cost of the board + plaster + plaster, so that the walls are ready for use or get the final color, is on average R real the square meter. This value already includes material and work.
Since the plaster can be applied directly to the masonry, it releases the chapéu and the dough. If the application is made in high quality, you save too much on the completion of the service because you don’t even have to paint.
Even if the value varies from place to place, the cost of applying gypsum with labor costs is around Rs per square meter, ie savings of more than 50%. It is worth thinking about the use of gypsum in a renovation or construction.
And now that you know all the tips for applying plaster without having to rent a specialized gym, just purchase the materials and roll up your sleeves. Good luck!
