Pour the warm floor – how to make a screed correctly
When setting up cement-sand (concrete) screeds, work performance technology must be closely followed. If not, the constant temperature changes caused by the coolant moving along the heating circuit may cause such a base under the floor with heating to crack.
If the floor beneath the heated floor is constructed improperly, the screed will probably become deformed soon after, rendering the heating system useless. It won’t be able to be restored.
Everything will have to be restarted. For this reason, it is crucial to understand how to pour warm water onto a floor correctly, as shown in the picture.
Temperature gaps
Incorrectly located compensation clearances are the main cause of cracks that frequently show up on the surface of the concrete base. In large rooms or with intricate layouts, installing a monolithic slab is not permitted by the warm floor arrangement guidelines.
The purportedly heated region in this instance is separated into multiple zones, each of which is marked by a damper ribbon that is 5–10 millimeters wide.
The following subtleties are considered when allocating temperature gaps:
- The size of each zone should not exceed 30 “squares”, and the length of the sides is less than 8 meters. The ratio between the parameters of the walls of the room cannot fail to correspond to the proportion of 1: 2.
- When the room has a complex layout, it is divided into zones in the form of a square or rectangle.
- In some cases, the trowel draws dividing lines by about a third of the depth of the solution.
- After the concrete hardening, the seams are sealed.
As stated in SP 41-102-98:
- Когда производится заливка теплого пола, при монтаже отопительного контура следует применять цельные трубы.
- When laying a pipeline crossing the temperature seam, it is necessary to protect the heat source with a corrugated shell of more than one meter long.
- Pipes must be fixed on the floor, using special V-shaped brackets or wire with a soft lining for this.
Preparatory work before filling
There are a few things you should do in advance of filling the heated floor, including:
- arrangement of the base for the solution;
- Installation of all heating contours.
After laying the so-called "pie," the screed is filled once a warm floor has been produced.
It is created in the following order:
- To ensure waterproofing A film made of polyethylene with a thickness of 200-250 μA is laid on the black base.
- Then to create thermal insulation use a thin layer of foamed polyethylene, one side of which is covered with heat -reflecting foil. You can use extruded polystyrene foam 5-10 millimeters thick.
- At this stage, the basis for fixing the pipes is mounted and metal nets with cells of 10.15 centimeters to perform reinforcement.
- After that they start fixing the heating contours. For which metal -plastic or polypropylene pipes with a cross section of 20 millimeters are used (more detailed: “How to make a warm floor from polypropylene pipes with your own hands”).
- In order to enhance the strength of the screed Sometimes they make additional reinforcement. For this, another row of nets is laid on top of the pipes.
- To obtain an even foundation beach profiles should be fixed – this is one of the requirements on how to properly fill the warm floor. It is necessary that the interval between the landmarks is less than the length of the rule. Mount the beacons using a solution or self -tapping screws and focusing on the level. They begin to install them with a zero (it is the highest) floor points.
- The final layer is the laying of the solution for the construction of a warm floor. Before this, you need to determine what to fill the warm water floor. The screed should rise above the level of heating circuit by 3-7 centimeters. This thickness allows you to distribute thermal energy evenly and provide the same surface temperature.
Tools and building materials for filling
In order to create a heated screed beneath the floor, you need to either prepare or buy:
- sand, cement, film made of polyethylene;
- dumping tape;
- plasticizer and fiber;
- mounting nets;
- thermal insulation material;
- profiles for the beacons;
- level;
- container for the solution;
- pipes 20 mm;
- nylon screeds for fixing to the grid;
- punch and screwdriver;
- construction mixer (you can use the nozzle for a perforator);
- rule;
- vacuum cleaner, broom;
- overalls (rubber boots and knee pads).
To fill a warm floor, you"ll need to carefully layer the materials for optimal heating and insulation. Start by laying out insulation panels to keep heat from escaping downwards, then install the heating elements, like electric cables or water pipes, across the insulated surface. Once these elements are secure, cover them with a suitable filler, like self-leveling compound or concrete, ensuring it completely encases the heating system while providing a smooth, even surface. Allow the filler to dry and cure as recommended before adding your final flooring, such as tiles or laminate. This process ensures even heat distribution and energy efficiency, keeping your home warm and cozy with a floor that"s built to last.
Features of pouring flooring with heating
Testing hydraulics is done prior to pouring. It is required to keep the pressure inside the pipes at 0.3 MPa while the screed is being arranged.
To achieve a high-quality concrete base, you need to be aware of the best way to fill the heated floor. For kneading and plasticizer, M400 cement is advised.
It is acceptable to move forward with the pipeline’s thermal test just one month after filling. The coolant’s initial heating cannot be higher than 25 degrees. After that, the temperature is raised by 5 degrees every day until the desired value is reached for this parameter.
Technology for arranging screed
Selecting the right type of concrete to fill the heated floor is a crucial decision. The consistency of the mixture should be such that the rule can easily level it.
A concrete mixer is needed to fill a large quadrature, but the solution can be manually kneaded in a container if the amount of work is small. The proper solution to pour on warm floors is explained in an instruction (see "How is a screed for a water warm floor" for more information).
It will require:
- 1 part of the cement, preferably the M400 brand;
- 4 parts of sifted river sand;
- water for kneading a test -like mixture;
- plasticizer and fiber -fiber (read: “We use fiber -fiber for screed – features").
Fill the floor after the solution has been prepared. Initially, a slide is used to distribute the mixture, and the surface is equally spread out with a shovel. They align the screed and move it along the guide lighthouses using the rule. Work needs to be done quickly to prevent the mixture from becoming unfit for use.
It is rarely possible to obtain a smooth surface free of tiny bumps at one time. Applying a layer of solution just above the profiles and using the rule to remove any excess in the morning makes things easier. The mixture needs to be solid but not have time to freeze, which is the most important requirement.
After that, the lighthouses are taken out of the screed to prevent rusting, and the resulting strokes are sealed using a newly made solution.
Following alignment, a polyethylene film is applied to the concrete surface and it is moistened with water. These occurrences have the ability to shield the foundation from rapid drying and crack formation. Do this for three to seven days.
Experts advise utilizing additional materials when filling the fill on their own. For instance, it is possible to arrange a concrete layer using a half-smoker on a warm water floor, which has benefits over other configurations (see "The device of a half-dry floor screed is the installation instructions"). It dries much faster and doesn’t require leveling the surface after application. Furthermore, there are no cracks or shrinkage on the partially dry screed.

How to fill the warm water floor – we will figure out the methods and tools
By reading the article, you will learn the proper way to fill the warm water floor. The primary requirement for success is a careful approach to carrying out every step of the work.
Filling the warm water floor: a guide
It takes more than just putting in high-quality furniture and lovely wallpaper to create coziness and a welcoming atmosphere in an apartment or any other space. The condition of the flooring is crucial. It ought to be warm, even, and smooth. Warm water floors have been particularly well-liked lately. They give the owners the freedom to independently control the house’s air conditioning and heating, turning it up in the winter and off entirely in the summer.
One of the most useful solutions for filling a warm water floor is rice. 2 concrete screed.
Families with small children tend to favor water warm floors more than others. The infant, after all, enjoys playing directly on the ground. Consequently, keeping this floor warm and cozy is crucial for the younger generation’s health.
It is best to call professionals if you have no inclination towards construction and repair work. However, if you choose to handle all the floor warming tasks yourself, you will appear to be in need of the guidance provided in this article.
How to fill the warm water floor?
The characteristics and kind of building materials are crucial, just like in any other kind of repair. Two distinct materials can be used to create a warm water floor that is both long-playing and of excellent quality:
- Cement -based solution (it is also called "concrete/wet screed").
- dry specialized mixture, that is, a half -fingered screed.
Every one of the materials mentioned above has benefits and drawbacks of its own. You must have a thorough understanding of the material properties in order to select one of the screed options.
Concrete screed
It makes sense that concrete is favored by builders. It is employed in a variety of jobs. However, it is important to remember that you will require a specific kind of concrete to fill the heated floor in order to achieve the intended outcome for the project. We are discussing cement that is branded higher than M-300. It is also advised to use worthy rather than sand because worthy has a stronger and more consistent adhesion.

Additionally, keep in mind that the plasticizer is a tool that needs to be added to the mixture. It won’t permit the screed of the future to fall apart. The plasticizer will aid in the screed’s 30mm thickness reduction, a fairly high indication that is crucial for high-quality repair.
Half -smoked screed
For very good reasons, this kind of warm water floor construction is more common. This option uses a lot less water than the traditional method, which is always a huge plus. In the end, the floor is defined by higher stability, density, etc.D.

Half-dry concrete dries several times faster than concrete screed. There is a short window of time available for repairs on this crucial feature. To enhance the coating’s quality on the semi-dry screed, polymer modifiers are advised.
Preparatory work
In any kind of repair, preparation is key because it determines how things turn out in the end. The entire preparation process for screeding with a half-dry mixture can be broken down into the following steps:
- thorough cleaning of the base;
- laying a layer of steam- / waterproofing;
5 waterproofing laying rice
- wall surface preparation;
- Installation of rails – lighthouses.
Rice. 6 the placement of the floor alignment beacons
Give the cleaning a lot of thought. Dust and other impurities that can deteriorate the outcome should be totally removed using a powerful vacuum cleaner. Waterproofing is an additional important point. It needs to be carefully placed on the floor with a continuous cloth. It is necessary to use a special damper ribbon to isolate the walls along the entire perimeter of the room. However, rails can be used as a lighthouse, exposing them to the cement mortar’s base.
Production of the solution
You should carefully consider whether you can mix the solution on your own to achieve the required composition and consistency at this point. If you are unsure of yourself, proceed to improve the kneaded mixture by following the directions on the container. You can insert your hand into the solution and make a fist with your fingers to verify that it is correct. When water is released simultaneously, the solution you created is too liquid. If there’s no response, everything you did was correct.
You can safely move on to the filling process after finishing the earlier steps. The flooring is split into multiple sections and filled with a mixture in order to achieve this. Ensure that the coating is no thicker than 40 mm. And always align the flooded surface rule with left and right movements—this approach will produce the best outcomes.
Grouting is a necessary step in the mixture-laying process. However, it takes twenty minutes after pouring to begin this kind of work. Kindly be advised that delaying this process will not be beneficial as it will become unnecessary after six hours.
Every respectable construction store sells a special grouting machine that is required to grind the surface with a qualitative finish. You can precisely align and compact the surface by using this machine. It is important to remember that this work only appears challenging. She can actually handle one person in a few hours with ease.
7. Kneading the fix in rice
We take note of the fact that, depending on the materials used, the water floor heating system can be launched in approximately one month following the completion of all work. The system ought to transition into a fully functional state over the course of several days. Excess air will exit the pipes during this period.
After reading about the primary steps involved in pouring a warm water floor, we can draw the conclusion that the lesson is not easy to learn and that it will cost money and take time. However, if you follow expert guidance in every way, the outcome will be better than you could have imagined.

How to fill the warm water floor
A warm floor offers the chance to maximize comfort within the home. You can effortlessly regulate the room’s temperature with the help of this system, negating the need for the central heating. However, installation needs to be done carefully, taking into account all technological advancements, and using the right materials. The device of the protective upper layer above the heating pipes is one of the most crucial elements. You can get to work after learning how to fill the warm water floor.
Filling the warm water floor: a guide
How to fill the floor
The warm floor can be filled with three different materials: concrete, self-leveling cord screed, or half-dry screed. All three approaches use basic technology and are essentially the same, but they also differ in certain ways. You must educate yourself on the primary benefits and drawbacks of each type of screed before choosing one.
Concrete screed
Apply concrete screed.
A pouring floor with a cement-sand screed is the traditional configuration. However, the screed needs to be stronger because it will be exposed to large temperature variations all the time. Since the filler plays a major role in strength, shifts are used in place of sand to create a concrete screed solution. Construction standards state that a premium filler for the heated floor should include the following:
- screening with a fraction from 3 to 5 mm;
- cement m300 and above;
- Plasticizers.
Unlike sand, the screening offers a more dependable and superior clutch. Low-quality cement will not produce concrete with the necessary strength, and when heated, the surface will inevitably be cracked. The plasticizer is required to prevent the screed from crumbling when temperature variations occur. Additionally, the screed’s thickness can be decreased from 50 to 30 mm by using the plasticizer.
Plasticizer for screed
Work the mixture using the following amounts:
- cement – 1 part;
- screening – 6 parts;
- plasticizer – 0.35 liters per 1 bag of cement;
- water – until a pasty uniform mixture is formed.
It is advised to incorporate a fiber-fiber into the solution when pouring a floor that has a complex configuration or covers more than 40 squares. This helps ensure that the mixture is distributed more evenly and removes the need for laying a reinforcing grid.
When filled properly, the screed is robust, long-lasting, and evenly heats the surface. The substantial weight and extended drying time of the concrete screed are its drawbacks. It is preferable to focus on the second technique, which involves applying a half-dry screed, if time is of the essence.
Half -smoked screed
This kind of screed differs from others primarily in that it uses less water. Fibers and polymer additives are unavoidably included in the solution’s composition. While ready-made dry mixtures are available for purchase, making the solution yourself won’t be too difficult.
A mixture containing polypropylene fiber for a semi-dry screed
The solution’s proportions:
- Cement M400 – 1 part;
- sifted large sand – 3 parts;
- fiber -fiber – 0.5 kg per cubic meter of the mixture.
Technology for creating and applying semi-dry screed
A tiny amount of water is added, fully blending each ingredient. It’s very easy to determine if there is enough water in the solution; just dial a small amount in your hand and give it a firm squeeze. If there was excess water present, it flowed; if the mixture was dispersed, water would still need to be added; however, if the solution retained its shape after compression and did not crumble or spread, it was ready.
Orienting the partially dry screed
The semi-dry screed has more important benefits than concrete, such as faster drying times, greater strength, less shrinkage, and nearly no cracking. Moreover, temperature variations have no discernible impact on the screed. The mixture’s reduced plasticity means that more work must go into creating the solution, which is a drawback. For the same reason, gaps develop in the screed’s thickness and the layer’s floor seal isn’t always consistent. The leveling layer must be shielded from moisture once it has dried.
Self -leveling the mixture
Self-equalizing compositions have certain benefits over regular cement-sand mixtures in terms of their properties. Since they spread due to their own weight, they are more plastic and do not require careful leveling. They dry out too quickly. There are two types of self-leveling mixtures: rude and finish.Only the rude ones are used to fill in heated floors; thick layers are not meant to be applied with the finish. Rude apartments, on the other hand, are on a gypsum and cement-based plaster; both of them work well for filling the heated floor.
An example of pouring water warm floor
How to fill a concrete screed
Selecting the right kind of screed to pour does not guarantee successful filling; proper technique is still required. Any mistake made during the production of this coating lowers the warm floor’s efficiency and causes the screed to break. Prior to the pouring stage, the base needs to be prepared, the heating system installed, and a waterproofing and reinforcing layer laid. Until the warm floor is laid, the damper tape is also fastened around the room’s perimeter. Making a screed can only start after that.
How to prepare a heated floor for screeding. Plan
The screed device’s scheme
For the task at hand, you will require:
- metal profile for guides;
- dry gypsum;
- a container for a batch of a solution;
- level;
- trowel;
- Rule.
Options for heated floor screeds
Step 1: Mark the screed fill line on the wall using the level. Remember that the solution above the pipes needs to be at least 3 cm thick.
Step 2: Knead the gypsum solution and place it in small heaps 20 cm apart from the cell along one of the walls. Place the guides on the answer sheet and adjust their level. There is a gap of 1.5–1.8 meters between the beacons. Gypsum dries very quickly, so spread out your lighthouse solution over the area in two or three doses rather than all at once.
Step 3: Prepare the concrete solution by mixing the dry ingredients in the proper amounts, adding water, and adding plasticizer.
Using the rule, the solution is dispersed across the surface after being poured between the guides.
Step 4. When pouring the floor, the pressure in the pipes should be 0.3 MPa, otherwise you can not lay the screed. The solution is poured between the guides and using the rule is distributed on the surface. You need to work very carefully so as not to step on pipes. Pouring is carried out portions, dividing the room into several sections. If the floor area is more than 40 m2. Between the sites, a damper tape is laid 5-10 mm thick. It is best to use a special inter-hydrogen tape, which has a T-shaped profile. It has standard parameters: width 10 cm, height 10 cm and thickness 1 cm. The tape is available for 2 m long and is very inexpensive. Mounting it is much more convenient than a regular tape. Deformation seams do not allow the screed to crack during temperature expansion. Pipes passing in the seams should additionally need to be closed with corrugation.
A deformation seam and a pipe joint sealed by corrugation are visible in the picture.
The screed is covered with polyethylene and allowed to dry after the entire floor has been flooded. After a day, lighthouses are taken out and a solution is used to seal the crevices. The floor is once more covered with a film, and to prevent cracks, water is applied to it on a regular basis. You can apply the finish coating as soon as the screed reaches the required strength and the humidity falls to 5–7%.
Although filling a heated floor may seem like a difficult undertaking, it can be completed successfully with the appropriate planning and strategy. Begin by assembling all required supplies, such as the appropriate kind of self-leveling compound or concrete, and make sure you have all the tools you’ll need. Before you begin filling, make sure the subfloor is clear of debris and clean. You should also confirm that the heating elements are correctly installed and operating.
Work methodically and spread the mixture evenly when filling so as not to create high or low spots. A level surface can be ensured with the aid of a trowel or long-handled screed. Because some materials set more quickly than anticipated, it’s imperative to work quickly but carefully. Even though a self-leveling compound will spread out on its own, you may still need to guide it to fill the entire space.
Give the material enough time to cure after the filling process is finished. The kind of compound used, the humidity level, and the temperature can all affect this time. Follow the manufacturer’s instructions exactly to guarantee a sturdy and long-lasting floor. Remember that it may take a little longer to activate the heating system even after the initial curing period.
After everything is in place, make sure the heated floor is operating properly by testing it. To prevent any abrupt temperature changes that could strain the system, raise the temperature gradually. If everything goes according to plan, you’ll have a cozy, warm floor that will improve the comfort and energy efficiency of your house. Although it takes time and careful attention to detail to fill a heated floor properly, the results are well worth the effort.
