How to fill the floor on the balcony with your own hands + video
On the loggia and balcony, the plate is constantly under the influence of the rays of the sun, wind and rain, and this, in turn, gradually destroys it. Self-leveling floors on the balcony are one of the methods of protecting this extremely important element.
Another screed is made in order to level the surface and insulate the room. The technology for creating works is quite simple, and therefore everyone can do it with their own hands. So, let's look at how to fill the balcony floor with our own hands.
There are certain types of materials on the modern market that allow you to pour floors on a balcony room. Each of them has certain advantages and disadvantages. There are options:
The use of a cement-sand mortar to create a floor screed on a balcony room is the simplest, as well as the budget option. All work can be easily done by yourself. But this method has one tangible drawback, which will be that the concrete layer must dry for at least 2 weeks.
Also, the surface requires regular spraying and covering with plastic wrap.
This is required to prevent cracking. To create a screed on a balcony room with a dry method, you need expanded clay and gypsum fiber boards. This method will require spending approximately 2 times more money, but this technology is much easier and faster to implement. It is not necessary to wait two weeks until everything is dry.
Expanded clay is an excellent type of insulation. After completing all types of work, you can use any finishing materials, for example, tiles.
The semi-dry type of screed is also a fairly economical option, because it requires sand and cement. But in this case, much less water is used when creating a solution, which is why the mixture will no longer be self-leveling. The consistency of the material should resemble wet sand.
After laying the layer, it takes only three days for everything to dry perfectly. If you follow a simple technological process (for example, do not work while it is raining outside), you will get a monolithic and strong plate that will perfectly keep heat. Any type of topcoat can be laid on top. A screed with a warm interlayer is performed if the balcony or loggia is very old or serious protection is required in the cold winter. In the role of a gasket that is resistant to frost, experts recommend choosing lightweight foam or even expanded polystyrene.
With this method, the level of the balcony floor begins to rise strongly, but it will provide excellent noise insulation and a warm winter.
But the second floor most often has the coldest balcony, since on the first such a design is usually completely absent. Because of this, it will be more blown by winds during the winter time period. The floor on the balcony / loggia is a simple reinforced concrete slab that will not be finished. For this reason, most of the money and time is spent on the preparatory stage for laying the finishing layer.
If the stove begins to move away from the house wall, then first you need to carry out major repairs. Which material is best to choose for pouring will depend on the type of balcony:
In case the room is glazed, in which heating by means of a radiator or underfloor heating is provided, it is possible to use materials for screed that are intended for internal types of work.
Glazed balconies that are not heated are protected from snow and rain. But with sudden changes in temperature, condensation can appear in huge quantities. To properly fill the floor on the balcony with your own hands, you need to use moisture-resistant materials.
But here you need to remember that balcony slabs are an element that is fixed on only one side. You can't overload it too much.
Pouring the floor is required with care. If the thickness of the layer is required to be made small, then the cement mark should be much larger. When it is required to raise the floor by more than 0.2 meters, then the cement-sand screed is not used. In this case, the best option would be to install the floor on logs.
They do not make the structure very heavy, and a concrete base is an ideal choice for lifting up to 5 cm. The need for formwork will depend on the case.
After you determine the required materials, you need to find the floor level. This should be done through different levels. The most popular are:
When using water, it is required to make a mark on the wall of the loggia anywhere. Using such a tool, places at a similar height are also marked on all other walls. It is required to draw a line (horizon) along the obtained points.
It is visually important to determine the highest places on the floor, and then measure from the drawn line.
Note that the bubble level is almost the same. But in this case, you must first determine the highest points, and then draw a horizontal line from them.
It is best to use a laser level. It must be installed on the highest section and turned on.
After that, the device will apply a laser mark on the surface of the walls, which will correspond to the floor level.In case you have an open balcony, you need to provide everything so that the floor screed is at an angle to the street. This is required so that moisture does not accumulate on the floor surface. One incline centimeter per meter of width will be sufficient.
For each type of screed, the preparation technology of the base is practically the same.
The finishing type of coating must be perfectly insulated, because moisture and temperature changes will affect the plate. A well-made screed can guarantee you perfect structural integrity for a long operational period. In certain cases, to save time, concrete is required to be poured directly onto the existing coating, but only when it is in a satisfactory condition. This option is valid, but it is still wrong.
Floor coverings become much higher, and the strength of the screed itself is greatly reduced.
Only a fully cleaned plate can guarantee an excellent result. To begin with, you need to take out all things and remove door trims, as well as baseboards. It is advisable to carry out work in a respirator or mask, because during dismantling work there is usually much more dust. It is better to wet the floor and walls from time to time from a spray bottle.
Methods for cleaning the plate:
But it is imperative to ventilate the room, and a thick layer will need to be knocked down.
It is also important to carry out preparatory work on concrete slabs for pouring. To do this, it is important to remove chips and loose areas, cover bare reinforcement places with a primer, and seal up a poor-quality area with an adhesive or cement mortar. After that, it is important to carefully remove the debris and vacuum. The screed will not adhere well to the base, which is dusty. At the very end, you need to prime everything twice.
It is important to apply a deep impregnation type primer. This material helps to remove dust residues and create an insulating layer. On average, drying takes about 8 hours.
How to fill the balcony floor with a liquid screed? It is usually made of sand and cement only when it is required to raise the floor by no more than 5 cm.At the maximum, such an indicator can be 8 cm.
If the layer is poured even thicker, then the load on the balcony slab may be excessive, and this is very dangerous. The pouring technology includes certain stages.First you need to measure the height for the future home. This is done through any level.
If you plan to use a liquid screed, then you need to additionally think about the manufacture of formwork.
It is required to install it around the entire perimeter of the room. Next, you need to lay a waterproofing layer. Most often, a simple plastic wrap is used. It must necessarily go beyond the formwork limits by several cm. After the mortar dries, it is important to cut off the excess edges.
Next, beacons are made. Installation is required to start from the edge. It is most convenient to attach them to screws. After the beacons are fixed, you can begin to carefully fill the floor.
It is important to smoothly distribute the mortar between the installed profiles.
Distribution is required to begin with a trowel, and then apply a piece of profile or rule. This helps you achieve perfect results. After a few days, and after hardening, you can remove the beacons. It is important to wipe the remaining traces with a solution. it is also important not to forget to grind irregularities.
Perfect drying of a liquid screed will last about 2 weeks. In the early days, the surface needs to be slightly moistened to avoid the appearance of bubbles.
And such a screed option on the balcony is very easy to do. This method involves the use of lightweight materials, due to which the plate will not be overloaded. This option is perfect for Khrushchev and other old houses.
As a rule, porcelain stoneware with a fraction size of 1-2 cm is used as the main material, as well as quartz sand, fine slag or perlite. It is required to perform similar preparation work as for a liquid screed.
It is required to clean the slabs, install the formwork and lay a waterproofing layer. After that, the material must be poured out and tamped tightly so that the layer reaches the edge of the formwork, on which the rough coating will be fixed. In the role of this type of coating, two plywood layers can be used, which are treated with some kind of antiseptic.
This is required in order to prevent the growth of mold.
