Plaster has been the main finish for a number of building projects for many years. Some mistakenly believe that such work is difficult to perform, but in practice this is not so. You just need to know the scheme of work and have the right tools at hand. And our article today will tell you how to perform this operation correctly.
Pros of the operation
Slope plastering has its positive and negative points. Before starting work, it is better to familiarize yourself with them:
- The window frame and the door opening become reliable.
- Decreases noise reduction.
- Since all the cracks are removed, there is no access to dust and moisture. This prevents the formation of mold and mildew.
- No fear of temperature changes.
- Different design styles.
Flaws
There are not many cons. Not everyone wants to mess around with a dirty solution. The work takes time. Apply the cement-sand mixture more objectively inseveral layers, and each should dry completely. And this is a very long time.
Working with windows
Plastering the slopes of plastic windows is a necessary process after their installation. This is required not only for aesthetics, but also to perform protective functions. Plastering is an old method, but relevant to this day. All this can be done by a person without special skills and experience. Before starting work, you should get a little theoretical knowledge.
If the operation must be performed in an old house when dismantling windows, then a number of problems arise. The slopes themselves can collapse. However, the plastering of window slopes produced has a number of positive aspects:
- Strength and reliability to mechanical stress.
- Long service life.
- Inexpensive process.
You need to do everything carefully, otherwise cracks may appear. This is a disadvantage. The ability to use a spatula will solve many problems and will allow you to plaster window slopes with your own hands. Before starting, you should prepare everything.
What do you need for finishing work?
At the first stage, you need to purchase the required materials and tools. This includes:
- Plaster mix.
- Putty and primer.
- Brush.
- Spatulas. For convenience, you need to have two - wide and narrow.
- Trowel.
- Building level. Its length must be at least 50 centimeters.
- Tape measure and protractor.
- Capacity forcreating mortar and water.
If this is dismantling, then you need to remove an extra layer of old plaster from the slopes. They do it in various ways. It is believed that the plastering of slopes with gypsum plaster is the most effective. But more often choose a cement-sand mortar. It is easier for beginners to work with a gypsum-based composition, because it is more plastic and easy to apply to the surface. Remove existing gaps before starting work.
It is important to protect the surface of windows and doors from getting the solution on them. Because it can be devastating. Thick paper is suitable for window sills; many places can be sealed with construction tape. It is better to remove the door leaf at the time of finishing. In addition, batteries or other things that are in the repair area are better protected. Otherwise, they will then have to be scrubbed for a long time.
When windows are ordered, large gaps are removed by workers. However, small gaps often remain. Foam for installation work will cope with them. After it dries, the remains are cut off. It will be easy to wipe such a surface. Before finishing the slopes with plaster, the surface is prepared:
- Completely stripped of old paint, plaster or other additions.
- If the entire area is smooth, then small indentations are made on it to adhere the new material to the surface.
- In order for the adhesion of the finishing material to occur well, a primer is used. With a brush, it is applied around the entire perimeter.
- Once all preparations are completed, the next phase begins.
What's next?
Further, with the help of a goniometer, the "angle of dawn" is determined so that the room is light. In order for the plaster of the slopes to turn out to be of high quality, it is impossible to do without the installation of beacons. They use wood or metal. But plastering slopes with gypsum plaster can be done if the application layer is not too wide. If there is no experience in such work, it is worth purchasing ready-made beacons. Fasten them with nails, screws and any adhesive mixture.
Methods for leveling the surface
When all the initial stages of work are completed, the process itself begins. The entire area is covered with the prepared solution. How to make a window slope with plaster? Next, the entire space between the beacons is leveled. This is done everywhere. As soon as the solution is completely dry, the beacons are removed. Do not forget that they line up by level. After that, free space remains, it is removed in the same way. Experts believe that plastic windows can expand during temperature changes, which will lead to cracking of the plaster. How to avoid it? It is necessary to make a small groove between the frame and the slope, pour a simple sealant into it. It will restrain such processes, and cracks will not appear.
Grout
Slope grouting is done until the entire plane is level. After construction work, it takes time to dry. This takes up to ten hours. And already on the finished surface, the final procedures are done - painting. But it is not always done, but only if desired.
Working withdoorways
It is believed that it is easier to deal with doorways than with plastering window slopes. But in the process of work, the main part of all actions is similar to the previous operation. Everything is done in several stages. The surface is cleaned of old material and primed.
It is believed that working with front door openings is easy. Some people think that difficulties arise in arched openings, but this is not so. The whole process will take place according to the rules, in the end everything should turn out according to the level. The mixture is best applied in the same way as on window slopes. Installation of the door is done strictly parallel to the floor. Perforated corners are indispensable here.
Basically, work is carried out on the front door, and it is subject to temperature changes. Therefore, slope plastering has its own characteristics:
- Everything that is next to the box (old plaster) is completely removed.
- Small notches are made for the sealant. You can use a simple knife.
- Apply primer over entire work surface.
- Sealant is poured, all residues are cleaned.
Working on the surface
Most often, when installing a doorway, a large amount of work is obtained. The fact is that the surface is severely damaged, cracks expand, etc. Therefore, you should immediately prepare the plaster with a margin. Builders say that actions should take place in several stages:
- If there is a large surface damage, you need to dostarting cover. This is a simple grouting of the slopes of the front door with the same plaster.
- The second stage will be the final one. As soon as the first layer is completely dry, you can proceed to the next work. The entire surface is primed, at this time the solution is being prepared. Apply in a thin layer up to three millimeters. Using a spatula, the entire surface is rubbed. For the hitch to be good, you need to wet the tool. The corners are aligned and further staining is performed (but not necessary).
The whole process is done in the same way as in working with window slopes. It is required to have the same set of tools at hand. Much depends on the choice of solution, so special attention is paid to this. Some believe that it is important to put protective corners before starting work. This is a steel sheet with holes all around, which is required for the mixture to get into them and adhere to the work surface.
If you do not use such protection, then the corners will be damaged during the operation of the door. This is done with all external and sometimes internal corners. In addition, such an addition will give clarity and accuracy to the doorway. It is better to install the tape on putty - it will be more reliable.
Making corners
Here is how the basic steps are performed step by step:
- The putty is kneaded by hand to avoid lumps. Then the corners are cut. Better if they are small. With such corners it will be more convenient to work. If there is no experience,the construction process should not refuse recommendations.
- When the preparatory work is completed, the mixture is carefully applied in a small layer to the inside of the corner.
- After, in turn, the corners are applied to the wall. They are pressed in such a way that the putty comes out. The latter is removed with a spatula. In order not to throw away the material, it can be distributed on the outside of the corner.
- It is necessary to look at that there are no cracks, and the corner lay flat without bumps. Only after the control is applied the next layer in an identical way.
- Once all the corners are in place, you need to go over them with a small layer of putty. This is required in order for the entire surface to become smooth.
Such work leads to the fact that all angles will become accurate, and the plastering of the door slopes will be neat. The result will be of high quality. Most often, this process is required to be performed after the doors have already been inserted. But it is better if these procedures are done before the door is installed. This will help prevent building materials from getting on the surface, which can be easily damaged (because the material dries quickly).
Experts say that before starting work, you need to purchase materials with a margin in advance. It should be well calculated how much it will take, so as not to buy more, but to work with one composition. Even if the door slopes are plastered with your own hands, you can purchase all the materials in bulk to save money. Repairs are always costly and time-consuming. Beginners needdo everything carefully and do not rush. It is better to start in the morning so as not to stop halfway.
Features of work
Every builder with experience knows the nuances of slope plastering. The following tips will help you do everything quickly and efficiently:
- For accurate and successful plastering of slopes, you need to have a bucket of water nearby during work. When the surface is moistened, the putty or cement-sand mixture is fixed better and better. Wetting a little is not enough. It is necessary that water gets into all the cracks. This is what a sprayer is for. If it is not available, you can use a brush and spray over the entire area with sweeping movements.
- To maximize adhesion, you need to throw the slopes with plaster windows or doorways. Movements should be strong and sharp. It is recommended to pre-train on an unnecessary area so that the result does not upset.
- When working with cement-sand mass, you need to add a little gypsum to the composition. So the clutch will be stronger. Much depends on what surface the work is being done on - wood, concrete or brick. It is not necessary to throw a mixture on the latter. It holds perfectly and is easy to apply with a spatula.
Other recommendations
When filling the space with sealant, you should use masking tape. After the work is completed, it is freely removed. Before starting the plaster, it is worth evaluating the surface and choosing the right material for grouting. If this is not taken into account, then as a resultwork will be in vain. Plastering should be carried out over the entire area, without interruptions. All corners and joints must be with expansion joints, otherwise cracks will appear. It will take a large amount of money to hire workers to plaster slopes, but when you do it yourself, you can save a lot. The process itself will not be difficult.
