How to make a warm tie

A qualitatively made warm floor creates a winter cozy atmosphere in the apartment. In order not to have problems with the heating system, it is necessary to adhere to the warm-alone installation technology, starting with the pouring of the screed.

1
Appointment of tie

The screed performs several functions:

Lines the base of the floor before installing the heating system.
Creates a protective and insulating layer between coolant twists.
Prevents mechanical damage from external loads.
Does not allow heat loss towards lower overlap.
The top smooth layer is used as a substrate for decorative flooring.
Equally distributes heat over the entire surface of the floor, increasing the area of \u200b\u200bthe heat of the surface.

For the warm floor make two ties - the draft (the lowest) and the first one. The blacks is performed in the following sequence:

Before filling the floor, perform all work on the walls of the room: lock the wiring, align the plaster, set the windows, etc.
Clean the floor base from irregularities - tubercles, pebbles.
Set lighthouses by which the upper surface will be exhibited in the horizon.
Prompt the bottom of the walls up to 40-50 cm, ensure an angle of 90 degrees in the corners of the walls to properly install the insulation. A flat surface is needed for fastening the damper tape before pilting screed. For a rough screed tape is not put.
Pour the prepared floor with a cement-sandy mixture with a thickness of 5 cm. Align the surface into the horizon with the help of measure using previously exhibited beacons.
After frozen, clean the surface from the garbage.
A rough screed can not be performed if the ceiling plate with a surface of good quality is at the bottom. If necessary, make all the slots on the stove and remove the protrusions.

Installation of insulation and heating system

To put the insulation on the prepared surface. Top to install the reinforcement grid with a cell of 100 × 100 mm. The grid is necessary to prevent the appearance of cracks on the screed. To the lower parts of the walls, fasten the damper tape from polyurethane foam to compensate for the expansion of the screed when heated (so that cracks appear on the floor). Place the heating system elements (cable or pipes).

Preparation of the solution for finishing screed

For a finishing screed, a disconse-based concrete is required. It turns out when mixing cement and fine-grained crushed stone with sand. On 1 part of the cement accounts for 4 parts of rubble and 3.5 parts of the sand. Often, plasticizers facilitating mixing mixture are added to the solution. You can add a special strength to the solution to the solution that will give concrete. When using Armovati, the reinforced grid in the screed can not be installed.

The number of consumables depends on the thickness of the screed, which is recommended to make a thickness of 5 -10 cm. The thickness depends on the size of the heating element. The layer of concrete above it should be from 30 to 50 mm. If you can buy a ready solution, order concrete brand 150, it is intended for residential premises. Concrete brand 300 is used in industrial buildings, it is more expensive.

Work before filling tie

Before filling, perform the following works:

Create a pressure of 1.5 ... 2 atm in the system. To prevent squeezing pipes. Water do not warm.
Install the lighthouses for which the screed surface will be exhibited.

Pouring pistoling

Start pouring a solution from the wall opposite to the door. Concrete tamper with chopper or robbles to remove air from the mixture. Control the thickness of the layer using a long rule that moves through beacons. On the squares of more than 40 square meters. m. It is necessary to make the temperature seam. If you are reinsured and make the temperature seam after 20 sq.m., no one will be worse. Align the surface of the finished screed rule.
