How to plaster walls: characteristics of technology and material selection
Before you begin the plaster surface, it is necessary to accurately represent all the features and nuances of this process. In this case, for the novice master will not remain insurmountable obstacles, and the result will be close to professional.
In addition to theoretical knowledge in this field, it is important to get the basic practical skills that will help in future work. It is best to first practice on a small less noticeable area. This will give you the opportunity to test their own capabilities and to identify typical errors that occur in the process.
Experience plaster useful for any owner of an apartment or private house which prefers to do the repairs yourself. Plaster is often used for leveling the surface, which need the walls of almost all the old houses.
It is important to choose the right plaster mix, taking into account the features and the material from which built the wall. It is also worth considering the type of surface and characteristics of the environment. This largely depends on outside or inside of the building will be. Consider the features of technology for each surface type.
How to plaster a brick wall with their hands
In order to plaster a brick wall, it is better to use a mixture which has been made on the basis of cement. Sometimes in the composition include lime, which gives the mixture further plasticity. This allows the use of plaster in areas which are characterized by high humidity. Or in the case where work is carried out outside the building.
The procedure of applying the plaster to the brick wall takes into account the following recommendations:
- a layer of a mixture which is applied to a brick wall should not be more than 30 mm. it is important to know that if the layer thickness more than 20 mm, as the base, it is necessary to use a grid-netting. This will allow to keep the layer of the mixture and make it more reliable, not allowing the plating will eventually fall away from the wall. Shtukaturami thus can be both external and internal walls of the building;
- to ensure that the end properties of the coating meet the requirements necessary to produce the mixing of all ingredients, observing the following proportions: 1 part cement you need to add ¾ parts sand, pre-clearing and sift it. Then water is added and all the ingredients are mixed until until the solution becomes plastic, while preserving its thickness;
- another option is a cement-lime mixture. For its preparation will need 1 part cement and 5/7 parts of sand and ½ part of lime paste. In this case, you must first mix the cement and sand then add the lime, previously diluted in water to the consistency of milk.
A useful tip! If the result of the preparation of the plaster according to all the recommendations the mixture is still too thick, you can add a small amount of water.
One of the most difficult cases – the need to plaster over bricks. Its surface is too smooth and this significantly degrades the adhesive properties of the plaster. In some cases, the use of reinforcement mesh may not be effective and plaster flaking pieces or just slipping on the surface. For such complex surfaces, there is an affordable solution in the form of a special priming compositions.
In such cases, you can ask for recommendation for the professional Builder. It will help to choose optimal variant of the primer mixture and a suitable reinforcing mesh with all the features of a surface.
Although many people prefer to do everything yourself by watching training videos. For beginners to plaster walls may seem difficult but necessary skill is formed quickly, and after a few hours of training to apply the mixture smoothly and beautifully it will be much easier.
Please note! Can be very helpful video, as a newcomer with his own hands to plaster walls of plasterboard. This process has its nuances and, if necessary, should be considered on an individual basis.
How to plaster walls: video manual for working with concrete surface
Working with concrete surface has its own nuances. If the surface is smooth, will require prior preparation and application of primer, which is added quartz inclusions. This allows you to make the wall rough and provide the necessary grip surface with plaster. To increase adhesion of the mixture and the walls, at the stage of mixing in the solution is recommended to add the gypsum powder.
The better to plaster walls inside the house, if we are talking about concrete surfaces? For this purpose, suitable gypsum-lime mortar, which can be prepared using the following components: 1 part gypsum, and ¾ part lime. First the gypsum is mixed with water. This should be done very quickly to prevent the thickening of the mixture. Then add lime solution and again all of this quickly mix until smooth.
Complex treatment process is not required if the concrete wall initially has a rough surface. In this case it will be enough to use traditional technology application of plaster.
A useful tip! Experts say that regardless of the type of concrete wall to be plastered, it is useful to apply a coat of primer of deep penetration.
Than plaster the walls in the bathroom: the advantages and disadvantages of various options
Special attention requires the answer to a question than to plaster walls in the bathroom under the tile. Complex operating conditions characterized by high humidity and constant temperature changes can affect the condition of the coating.
Choose to paint the walls in the tub have two options: cement and gypsum composition. The first option provides excellent waterproofing, in conditions of high humidity is a huge advantage. In addition, the material has a vapor resistance and extremely high durability.
But the use of gypsum plaster for finishing the bathroom has some nuances that have to be taken into account. First of all it concerns the thickness of the layer. It should not exceed 20 mm. And before you start laying the tiles definitely need to treat the surface with primer.
Thus, the bathroom is better to make a plaster wall with cement mortar. DIY material is easily applied, and its characteristics show that the coating will last for many years and would be a good base under the tile.
We should also consider how a novice with his own hands to plaster the ceiling. Video lessons demonstrate all of the complexities and subtleties of this task, so that the owner is to follow the recommendations for obtaining a good result.
How to plaster walls with their hands, especially working with foam
One of the main conditions of work with the foam – the use of reinforcement mesh. In this case, it is acceptable to use as plaster and cement mortar. Most efficiently to prepare the surface by treating her special impregnating primer, which is able to penetrate deep into the surface. But sometimes still require the use of additional measures, such as consolidation of special reinforcing fibreglass mesh, which is called “junctions”.
Responsible approach to the choice of materials for plastering walls determines the service life of the coating and the level of comfort in the process. In specialized stores you can find ready mix for all types of surface. So if there is no desire to mess with mixing, you can just buy the finished version. This product is simply diluted with water, after which it is ready to use. Moreover, the manufacturers ‘ recommendations will help to know better than to plaster the walls in a particular case.
Important! Given the variety of dry mixes, they are very easy to get confused and buy not what you want. Therefore, it is recommended to read carefully all the instructions and recommendations made by the manufacturer of the products.
As a newcomer to plaster walls with their hands: video manual
You must carry out preparatory works aimed at cleaning of the surface of various kinds of pollution and remove the old materials. This step is important as it determines how good will be to keep the plaster in the future.
To ensure reliable adhesion, thoroughly clean the wall, eliminating all that may be between the base and the plaster. Cleaning method can be selected depending on the characteristics of the material that makes up the wall. All cracks identified during the preparatory phase is necessarily removed to prevent cracking of the plaster in the future.
To plug in the wall cracks in a variety of ways, each suited for a particular size of the injury. For small cracks that penetrate deep inside the wall, you will need an extension to reach the narrowest part.
Having found its base, are cleaned to eliminate dust and dirt. Then with a brush liberally apply the primer. When everything dries, the crack can be repaired with putty, prepared on the basis of gypsum or cement. Using a spatula, you need to try as best as possible to level the patch with the wall surface.
Shallow narrow fissure may be sealed with sealant or silicone composition. Usually included with the tube is a special nozzle with a thin nozzle, which makes it easy to conduct such operations, directing it deep into the cracks.
If you want to eliminate do extensive damage to, for this purpose you can use foam. Usually applied one layer of primer, then fill the space.
A useful tip! If in the process the excess foam made above the level of the wall, then they can be easily removed by cutting away with a sharp knife.
How to plaster a brick wall: surface preparation
Better than plastering the brick walls inside the home – a controversial issue. However, regardless of the choice, must be a qualitative procedure for the preparation of the surface.
Often faced with the fact that on the surface of brick walls already have a layer of old plaster. In this case, you need to efficiently get rid of it. You can use the water and sponge, a few times wetting the surface and waiting until the water is absorbed. This procedure will greatly facilitate the task.
Then with a spatula, the thickness of the working surface of which is at least 1.5-2 mm and hammer, old plaster strays. To do this accurately and at the same time effectively, first you need to gently tap with a hammer on one of the sections of the wall. The result of this procedure, the cracks will appear, which will allow the spatula to pick up the coating. If necessary, the handle of the spatula can also be tapped with a hammer to ease the process of removing the old flooring.
Why you need a mesh for plaster facade?
The main grid types, selection principles, applications, methods of plastering, application, tips and recommendations.
After removal of the layer of old plaster, you want to walk on a surface with steel brush or grinding machine. Then proceed to the deepening of the seams between the bricks. This will ensure the best adhesion between the plaster and the wall. It will be enough to deepen their 5-7 mm.
The final stage of preparation of the brick wall is cleaning the surface with a soft brush and damp cloth. Then it remains only to apply a layer of primer of deep penetration. Moreover, it is better to do it in two coats, after letting the first layer dry before applying the second.
Features surface preparation concrete walls
Compared to brick, concrete wall be cleaned much easier. However, due to a more smooth texture, apply plaster so that it is kept will be more difficult.
In order to remove the surface layer of whitewash, thoroughly moisten the sponge with water and wipe the wall. Then use the iron brush to clean off unnecessary layers and again carefully wipe the surface.
Another way is to whitewash applied over a thick layer of paste. After complete drying, using conventional spatula, the entire top layer can be easily cleaned.
When you are finished cleaning, you can go to inflict shallow cuts on the surface. This measure will allow to provide grip. Despite the fact that their application will require a lot of effort and time, this process is very important and determines the result of the work, so to neglect this step is not necessary.
Some prefer to use a more simple way, not requiring incisions – primer and the addition of quartz sand, followed by plastering walls with cement-sand mortar. Due to the small fraction of it is retained on the surface creating adhesion between the plaster and the wall. However, this method is not always effective, and to ensure its effectiveness, it is recommended to test on a small area of the wall.
A useful tip! To determine how effective the method is quartz sand will allow a simple test: primer sand applied to the surface and let it dry completely. Then the wall you need to hold your hand. If the sand starts to crumble from the touch, then, will have to attend to the creation of cuts on the surface.
Features of preparation of wood surfaces
The process of cleaning wooden surfaces is the easiest of all the tasks. In this case, it is sufficient to knock on the wall with a hammer, and the plaster will just crumble to the floor. In advance it is recommended to lay plastic wrap to avoid contamination and facilitate the cleaning process.
For fixing plaster on a wooden surface need to fill special wooden reechki. The people are called shingles. With ordinary nails, they are stuffed all over the wall, focusing on the diagonal. This allows you to create not only a great base for laying the surfacing material, but at the same time solves the problem with the need to create beacons that are required for leveling the surface of the wall.
If after the removal of the layer of old plaster, discovered underneath shingles, it is necessary to shoot down and make a new one. Wooden elements quickly come into disrepair, succumbing to rotting, insects and the influence of time. In addition, often the old shingles is the source of the odor.
It is important not to forget about the necessity of applying protection to all wood surfaces and elements. The necessary antiseptic to prevent the appearance of fungi, mold and harmful insects in the wood. The composition is applied on each element and on the wall before you get the shingles, and then again after the installation is complete. This allows to provide the maximum level of protection.
There are times when instead of the wooden reechek crates use a metal mesh netting. It is also a valid option, however its thickness shall not be less than 3 mm, and the bracket must not be carried out to the surface of the walls, and specially trained staff.
How to plaster walls with their hands: video instructions for placing beacons
Since one of the main objectives of plaster – the maximum level the existing surface, you’ll need guidelines, which otherwise are called beacons. To understand how to plaster walls on beacons, you need to understand why and how they are portrayed. Do this use a level to continue to be able to make the surface as evenly as possible.
Usually for this purpose, metal rails, which fastening is carried out with the help of a plaster solution. This method is good because the plaster dries quickly and does not allow the profile to move, hold it in a predetermined position. To place these beacons need approximately 1.5 m from each other.
A useful tip! If the level is too short and its length is not enough, in order to check the evenness of the mounting of beacons, you can use a long bar. It puts to one of the guides until the mortar has not dried up completely, and to its centre is applied a level.
As an example, you can find instructions on how to plaster walls with their hands without beacons. The video will demonstrate other options surfacing.
The rules of applying plaster to the surface
Plastering of the surface consists of three stages, each of which is applied a layer of the solution. Each one is different and fit for a specific technology which best suits his purpose. The first layer is the most dense. He pounces on the wall and in fact a draft, on top of which in the future will be laid flat and smooth layers.
The first layer is carried out using a trowel or just your hands. It is important to remember that in the case of the contact solution skin, you need to take care of protection in the form of rubber gloves. The thickness of the first layer depends on the base: for brick or concrete walls will be sufficient 5 mm, but on the hardwood you’ll need a layer of the order of 8-9 mm given the sheathing.
The second coat should be applied more carefully, but still it is not finish. It is applied with a wide putty knife or trowel, bringing the solution to a pasty consistency. The thickness of the middle layer should be about 7-8 mm.
The coating prepared with the addition of fine-grained sand that does not contain large inclusions. The consistency of the solution should resemble sour cream that is exactly to go and smooth out all the bumps that are left after applying the first two layers.
Beginners in this matter to eliminate the risk of error will help the purchase of ready mix for each layer available in any hardware store. Their compositions almost always promote good adhesion and provide a solid and reliable coverage.
Also it is recommended to watch the video of how to plaster the wall corners. Of course, with a smooth surface is easier to work with, but to align the corners can take some skill, especially considering how imperfect are the original data.
How to make mortar for plaster with their hands
Despite the opportunity to save yourself the trouble and buy already prepared, many prefer to try to do everything yourself and prepare the plaster for each layer with your hands. Consider some of the most popular recipes that are widely used and have won the trust:
- Cement mortar, in which to 1 part of cement, you must add 3 parts of sand.
- The mortar is lime-based, in which to 1 part of lime is added 3 parts of sand.
- Cement-lime: 5 parts sand to 1 part lime and 1 part cement.
- The composition of lime with gypsum: 1 part dry plaster is added to 3 parts of lime, mixed to a paste-like state.
Important! The obtained mortar should be plastic and easy to “disperse” in applied surface, but at the same time it should not drain down.
Before you begin kneading solution for the chosen recipe, it is useful to know that the prepared quantity must be used within one hour, so as to further plaster tend to lose some of its qualities such as ductility. In addition, such “late” material is poorly bonded to the surface.
Special attention should be paid to the solution prepared with the addition of gypsum, because this feature significantly reduces the shelf life of the plaster before applying to the wall. This solution should be applied immediately immediately after preparation. In addition, the duration of drying will be affected by the layer thickness: thin dry almost instantly.
In order to avoid mistakes and not to spoil the batch of ready mix, you need to carefully study the instructions, and only then move on to adding water, as the period of setting and drying can be different.
How to mix the solution: rules and recommendations
To mix a quality mixture independently, must adhere to the following procedure:
- in the container intended for mortar mixing, you pour the water. Then according to the instructions, fill 6-8 trowels ready mix and carefully mix everything, using the construction mixer;
- the remainder of the mixture is added gradually during the process of thorough mixing that avoids the formation of lumps and to give the plaster plasticity and homogeneity;
- then it is advisable to wait 2-3 minutes and again stir the solution. At this stage it is possible to determine whether there is a need to add water or dry mix to make the plaster thicker or more liquid.
Once again it is worth note that one batch shall consist of such number of material that you can use here and now. The recommendation is as follows:
- for mortar containing gypsum, the shelf life is limited to 25-30 minutes;
- if used was cement-based, this period will be 40-60 minutes.
Wanting to give the surface a finished appearance, many people prefer to put on top of a layer of coating that makes the surface perfectly smooth and provides an excellent base for painting. Video how to spackle the walls with your hands tells in detail about all the nuances of this process and allows you to complete the finishing work on leveling the surface.
