To finish coat on your warm water floor laid down perfectly flat and not subjected to rapid wear on potholes and mounds - you need to carefully approach the issue of the formation of ties.

Tools Required screed

before working on the formation of ties of warm water floor supply of essential materials and tools.For the work you need otbivochnogo cord wire for fixation of Lighthouse profiles, sharp knife, electric hammer and screwdriver, wire cutters, float and trowel, to mix the solution container and conventional shovel.

Tools needed for floor screed

Necessary tools for floor screed

Materials for screeds are cement and sand.For one 50-kilogram bag of cement you will need 1.5 buckets of water and 200 kg of sand.To screed had some flexibility - we recommend that you add to the mix a plasticizer - about 150 grams of ordinary liquid soap.As beacons used metal profiles 20 to 40.

most effective in warm water so-called floating floor screed, which is located on the insulating layer.As the insulation layer is usually used styrofoam slab.

Getting Started: deduce horizon

Around the perimeter of the room at a height of about half a meter draw a horizontal line.Use construction or laser level.

Weigh on the line distance to the floor, thereby defining the highest and the lowest point of the floor space.

After that, make a calculation of the required amount of materials for the tie.At the highest point of the floor to his level must add at least 4 centimeters.Draw a line indicating the upper level of your future ties.

Screed: preparing a base

Perform cleaning of the room base.Then place on its surface waterproofing: film or a special solution.The next layer put a Styrofoam plate as a layer of insulation.On top place the reinforcing mesh.Then, according to the selected pattern, place the pipe water heating.

on opposite walls of the room in advance on the marked line of top-level ties fix dowels.We stretch between them strong cord.

In the role of the lighthouse we will play a metal profile.It must be installed on the wooden wedges so that it coincides with the upper level of the stretched cord.

Lighthouses should be located 0.5 m from the wall at a distance less than that used for leveling screed rule.

Exhibited beacons must be firmly fixed on the floor surface.To this end, next to the profiles prisverlivaem to overlap screws ..

Note that the profile must not sag between fixings.If necessary add additional support.

Using binding wire, fasten the rails to the lighthouse screws, achieving rigid fixation lighthouses.

On our premises perimeter laid special damping tape, which should prevent the thermal deformation of the screed.

stirred solution of the composition described above.Liquid Soap gently add - its excess can lead to retardation.

The mixed solution in the container move on the floor and place it between the two selected guiding beacons, usually starting from the farthest corner of the room.

stacked weight solution should resemble the consistency of thick cream and a little gutter, but not to spread over the surface.

To avoid air pockets formed in the screed , it is necessary to constantly maintain the grid

Screed: to level the floor after hardening

Once you lay the tie across the flat surface is necessary to wait at least 2 weeks.All this time the screed should be regularly moistened with water.

After curing, take a scraper and remove the top layer of the screed so that the surface seemed to lighthouses.

In the next step, remove the weight of the screed metal beacons.Cut through the layer with a spatula ties (gently, so as not to damage the heating pipes), gently knock on beacons a hammer and then extract them.
