Step by step guide on the device floor screed with expanded clay with their hands

This tie is probably the best one.It has high strength, and this indicator is clearly superior to the screed made with sand and cement.It is especially advantageous to use this kind of ties in cases where the level of the floor in the room should be lifted.For example, set the shower tray, mount the floor heating system, or simply to align the plane of the floor surface.

Today I will tell you how to run the floor screed using expanded clay with their hands.

Advantages ties with expanded clay

• not react to sudden changes in temperature.It can be used in rooms with any temperature control;
• fireproof;
• expanded clay - lightweight material.Therefore, such a tie does not create additional high loads on floor slabs;
• much cheaper than other lining materials or mixtures (eg, self-leveling floors);
• helps align the significant differences in height.Sometimes other means to achieve or impossible, or very difficult (or not economically feasible);
• simplicity of arrangement ties.There is no need to resort to the services of specialists.

By the way, it is necessary to take into account the fact that there are situations where the floor screed with expanded clay is the only option.As already mentioned, the floor slab are experiencing additional stress if they do tie.The magnitude of this load depends on the thickness of the screed (i.e., its weight).And all the plates are calculated for a certain tensile strength.If you need a coupler of a few centimeters, and the weight of cement and sand is appropriate.Therefore, expanded clay in such situations is the best solution.

Preparations

Layout floor

surface is necessary to determine the highest point of the floor.That's it, and need to navigate, making the tie.Best assistant in this case - a laser level.But it is a tool for professionals and for domestic use to buy it is hardly worth taking into account its cost.Therefore, in the home will need an ordinary building level.

Installation Beacons

Please put the so-called "beacon" at the highest point of the floor surface.According to it, and will align all the others.How to fix these beacons is solved on the spot.You can "grab" alabaster, you can grout.The main thing - they must stand firmly.For their alignment in the absence of laser level used cord (twine, rope).If the tie is done simultaneously in adjacent rooms, the beacons are aligned on the same level (if there are no special provisions for any particular room).

seems no need to emphasize that the surface to "open" floor must be carefully prepared.In particular this applies to the closing of cracks, if any show up.

screed device There are several ways to tie everything.Let us consider the most simple, although it requires a bit more time.However, they can take advantage of even a person very far from the construction issues.

Prepared floor surface is filled with expanded clay (be sure to dry).We shall mainly be interested in the question of the thickness of its layer.It should be remembered that at the top of the fill thickness of the solution recommended in the 5 -. 6 cm, and therefore need to be laid concrete block is based on this condition.Naturally, in some place of expanded clay will fall more, some less.The main thing - it "evenness" across the floor space.This is controlled by beacons and holding lines, as well as through the level.Building level for more precise control rests on the concrete block at different points in the room.

After leveling expanded clay it is necessary to pour cement mortar.His "density" is determined "by eye".Objective: To dilute the grout has to "grab" the top layer of expanded clay.The result will be a film which insulates the entire packed expanded clay.After applying the solution water it should not go through it.After that you should wait until a cement "milk" does not dry out (about a day).

last part of the work lies in the casting solution coating (or other mixture).Beacons can be cleaned, repaired cracks after them.All screed is ready.It remains only to dry well.
