Smooth and durable screed for warm water floor

To screed for warm water floor was smooth and strong, it is necessary to strictly observe the sequence of actions.

Construction warm water sex can be made with your own hands.

In preparation for this procedure, you need to calculate what will be the thickness of the coating, and in what way is executed styling solution.

technology filling procedure is well established, however, in this case, there are features that need to be taken into account.

The installed heating system - pipes, joints, the sensors - must be carefully checked for serviceability and test.Only after these steps, get to work.

What is the tie?

Warm water floor on the structure is a complex engineering construction.Installation and laying of all the elements must be done carefully.

concrete screed performs several functions.First, it firmly locks the warming elements.The video shows how to fill solution on a system of pipes laid.

When filling and leveling the surface of the need to act so as not to move them.

If the pipeline is broken as a result of leveling, then the fault will require a lot of time and resources.

will have to Stroebe concrete base in order to get to the place where the break occurred.

Secondly, the tie is a ground floor.It must have a smooth, close to the ideal surface.The thickness of the coating to water the floor pre-calculated.

load, which acts on the basis of a warm water floor, changing when moving furniture in other cases.The strength of the coating is determined by the quality of the concrete mix.

Practice shows that the surface of the filling is done most common type of solution.It is prepared in a ratio of 1: 3 cement and sand.This composition is easy to knead with your hands.

This is first necessary to assess the scope of the assignment and its capabilities.You can also use ready-mix, which is sold in a store building materials.

What knead solution ties?

The arrangement of floor heating technology installation screed is considered the final stage.Quality surface can be done in several ways.

used for this purpose:

• concrete mix;
• sand and cement;
• semi-dry.

Each of these materials has advantages and weaknesses.The composition of concrete and sand-cement mixture is well known.Technology of preparation of the solution is simple and straightforward even for inexperienced workers.

Construction of semi-dry screed is used not so long ago.Practice has shown that it is most often used in the performance of their own hands.

concrete screed

screed for underfloor heating is made of cement brand M300 and above.When kneading the concrete mix is ​​recommended to use sand coarse fraction.It provides better adherence.

The solution may add a plasticizer.This supplement gives additional strength to the concrete.In the shops of building materials are sold ready-mix concrete for the floor screed water.

Sand and cement mortar

Preparation and laying of sand and cement mortar is the same as in the case of concrete.The thickness of the tie should be the same.The composition of the solution should be added to the plasticizer.

At work it is necessary to pay attention to the consistency of the solution.It should not be thin or thick, and quite malleable.

Quality is determined by leveling.If more effort is required, it means that the normal solution.

Semi-dry mixture

semi-dry mix for the screed floor heating has a number of advantages over other materials.The porous structure of the material improves the sound insulation.In operation, the screed does not use water.

Laying mixture is done in a conventional manner.Screed dries quickly and after that on the surface does not remain any defects.

material cost is lower than traditional counterparts.Movie filmed on video when using a semi-dry mixture.

Technology laying

Started laying screed for underfloor heating the water, you need to consider one thing.The array spanning layer must be routed expansion joints.

The rest stacking technology is no different from the usual work on the floors.When working with your hands, it must be remembered.

In small rooms up to 16 m expansion joints are installed along the walls.additional depreciation seams are made in a large room.

The seam tape is put damper.

This complex device is required to compensate for expansion when heated screeds.If there is no such payment, simply tie vspuchilis.

minimum thickness of the concrete screed above the heating element should be 5 mm.If it is to do less, it quickly crumble, unable to withstand the external load.

Excess thickness of the concrete layer will weight the construction of water underfloor heating.And this is just one of the negative consequences that occur as a result of violations of existing rules and regulations.

dry mixture, which consists of plasticizers, easy to use, but you need to skillfully handle it.Dilute it with water immediately before laying.

The same rules, it is desirable to adhere to and when mixing the concrete screed.

Preparations

First of all, you must thoroughly clean the concrete subfloor.On the plate is mandatory stretches plastic film, which performs the function of waterproofing.

Laying screed without this film threatens that moisture can leak on the lower floors.Then, this film must be put foam or mineral wool.

These insulating materials are most commonly used in the regeneration of warm floors.

on foam sheets stacked heat-reflecting film.Already on her stacked tube heating.The tubes can be metallic or polypropylene.On top of them put reinforcing mesh of metal.

next step set the beacons, which are necessary to be guided at a leveling screed.As beacons can be used metal profiles or large screws.

Height ties usually happens six to seven centimeters.When the beacons are installed, the heating system is fixed according to the design scheme, you can order the concrete plant or structure, which includes plasticizers.

Before you fill it, you need to test the functionality of the water floor heating system.It is important that the coolant circulates along the contour without interference and with no leakage occurred at the joints.

casting process

Before breeding and pour the concrete mix, you need to prepare all the necessary tools.To work need a shovel, and materok rule.

prepared according to the rules of concrete poured onto the floor so that it has a uniform thickness.The video shows the sequence of actions and milestones of the process.

layer alignment is performed with the help of rules.It is necessary to ensure that the surface of the tie was strictly aligned beacons.

technology is simple, but from the artist requires a skill such work.Often, all operations are performed by hand.

Care screed

The composition of the screed for warm water floor except cement and sand and include a variety of additives.For screed after casting requires care.Experienced builders know that the dry screed will crack.

In order to prevent the formation of cracks, the surface of the screed must be periodically watered with water.The physical data of the solution is gaining strength within four weeks.

No matter what the thickness of the base, the array must be fed with moisture.In the first 8-10 days, the surface should be moistened with water.Then lay a warm water floor with plastic wrap and wait for the final hardening.

final stage

According to regulations, the concrete design strength gains after 28 days.In practice, this term is rarely observed, and the surface condition is estimated empirically.

Here you can walk on the floor and continue to care for him.Continue to monitor and to dry the surface had cracks.Minimum load will not bring harm to water screed floor.

conduct testing of the heating circuit is not permitted before the regulatory deadline.

, it means that the composition of the solution has been chosen incorrectly or broken sequence If the screed for underfloor heating water cracks began to appear.

That is why all work on the arrangement of the screed for warm water floor to be performed strictly according to instructions.
