Let's consider how to plaster walls with gypsum plaster.
How to plaster gypsum plaster, we will consider today in detail. Everything can be done with your own hands then and the price of finishing will be much lower.
Plastering the walls with gypsum plaster is done not only in a large layer. Therefore, you have big bumps then you have to do the work with a cement composition and apply a gypsum composition to the finish line. The video in this article will show the entire progress of this work.

The main advantages of using gypsum plaster
Gypsum wall plaster is an environmentally friendly product, because it is created on the basis of a natural component - gypsum. Due to its natural composition, it will not adversely affect human health.
So:
- Many homes and offices use gypsum plaster in order to provide people with warmth in the room, because it forms a heat-insulating barrier, thereby protecting the room from street noise and protecting it from fire.
- Gypsum plaster (see Dry plaster gypsum mixture: how to use it correctly) possesses such a distinguishing feature: when the air temperature is lower in the room and the humidity is higher, it absorbs excess moisture, and when the air temperature rises, it quickly returns moisture back and creates a comfortable microclimate.
Attention: If suddenly you were flooded by neighbors from above and you have spots on the ceiling, then do not rush to buy the necessary goods and start repairing everything - after 2-3 days the spots will disappear.
- The porous structure of the plaster contributes to this.
- Treated with gypsum plaster surfaces make it possible to use already decorative coatings, while not forming any cracks. For concrete substrates, a gypsum mixture with priming materials is used.
- Immediately after application, it evenly lays down, and then reaches perfect smoothness. It takes 5 days before the final drying of the surface treated with gypsum plaster. After that, the surface is ready to “try on” the wallpaper. A positive result is obvious, and all this without special material costs and in a short time.
Be sure to check the condition of the base.
This task is mandatory for each plasterer, because the plane must be completely ready for applying the composition.
So:
- First of all, it is necessary to determine the unevenness of the surface. Then we will know the application layer. To do this, we attach the line along the diagonals and use the level to make the adjustment. We will immediately see what deviation we have.
- If the layer is more than two cm, then it will be necessary to align the plane with another composition. If the thickness is not large, then you can apply a gypsum composition. Plastering walls with gypsum stucco video is exactly what this will show.
- We make the alignment of the walls with gypsum plaster and it should hold flat on a plane. Therefore, if the surface is made of bricks, then it is worth deepening the seams. Then the stucco will hold well.
Attention: If some elements are not fully fixed, this can cause the peeling of all the plaster from its base.
- Such elements need to be strengthened or completely removed. The process of repairing the plaster is quick - they knock it down, and the surface is cleaned.If the old plaster is still well preserved, then you should not immediately apply a new layer, the best solution is to bring it even with a putty.
Principle of work
How to apply gypsum plaster now we will consider, this work is not as difficult as responsible. Everything is done in a certain order and sequentially.
Any room must be prepared in advance before starting the plasterer:
- Firstly, all wet work must be completed.. Because plastering works are carried out with complete drying of the surfaces.
- Mandatory - complete the wiring of the power and alarm and close the boxes of these systemsso as not to stain them in the process, and you also need to finish laying water, sewer, heating pipes.
- Drafts - the cause of poor quality work. If the room does not yet have windows and doors, then it is necessary to block something with all the open spaces. If windows are available, protect the frames.
| Protection of metal surfaces | Gypsum mortar can destroy metal alloys, causing corrosion. To avoid this, you need to cover all metal surfaces with anticorrosive coatings. |
| Degreasing the finished surface | After completing all work, check whether there are any unwanted spots and traces on the finished surface. If yes, then you can remove such stains with a special degreasing agent or water vapor. Do this if you do not want to quickly destroy your plaster. |
| Primer overlay | The base requires a primer (see Why do we need a primer: technological nuances of finishing work) The type of soil depends on what material was used in the base. If, for example, concrete, then it is necessary to improve the fastening properties. If the material is such that is capable of absorbing water, for example, porous-based ceramics, then hygroscopicity must be reduced. One coat of primer is sufficient, but you should carefully consider the process of applying it. |
| Protecting protruding corners | During work - all protruding corners can be damaged. To prevent this from happening, it is necessary to impose special metal corners on the corners, which will protect the corners when they are mechanically exposed. In order to choose the size, use scissors for cutting metal. |
| Joints between different materials must be strengthened. | To strengthen the joint between two different materials, it is necessary to fix a fiberglass mesh (see Fiberglass plaster mesh - types and scope) It will eliminate the occurrence of cracks. |
| Application of guide profiles during operation | Unfortunately, many masters do not use them, but they know that the possibility of obtaining a more even surface is greater. With their help, you can finish the job much faster. |
So:
- The application of the stucco mortar depends on a number of factors: the size of the surface to be treated, on the equipment, as well as on the personal tastes and preferences of the specialist.
- Depending on whether it is manually applied or in an automatic way - and the solution is different. The first group is for the manual process, and the second is already for the machine process. Regardless of this, universal solutions are created that are suitable in both cases. Application of the solution requires considerable experience. The surface is processed in only one layer.
- In what situation is it necessary to apply a second additional layer? When the room is completely repaired, there is a need to strengthen the plaster with a nylon mesh. It will close the openings in the walls, and also exclude the formation of new cracks. In this case, a second additional layer of plaster is required.
- The second layer is usually applied immediately after the first, when it is still wet, and if the first layer is already dry, then this should be done only after priming.
Finish finish
Video stucco walls with gypsum stucco will also show the finish. The fact is that you cannot apply the coat completely smoothly. It will need to be leveled.
This is done as follows:
- Take a grater and attach a grid to it. After that we do circular movements on the plane. First, we use a grid with a large cell.
- After that, we look, if there are sinks, then we need to seal them with a mixture and at the same time use a small spatula.
- We are waiting for complete drying and walk along the plane with a grid, but just apply a smaller one.
Caution: If the plane is large, then it is better to use a mechanical path. For this, a grinding machine is bought. This will greatly speed up the process.
Now you know how to plaster walls with gypsum plaster. Take a look at the photo and take your time purchasing materials.
