Repair floor

It should be laid under the linoleum backing: its purpose, choosing the best option

It should be laid under the linoleum backing

The question of whether the support is necessary for laminate,and assumes a definite yes. The relevant question regarding the linoleum, causing a lot of debate. Some believe that the substrate under the linoleum does not need it, while others believe in its necessity. Of course, everyone decides for himself whether he needed the support, however, it is recommended to make a decision to learn the basic functions of the substrate, its advantages and disadvantages.

The main function of the substrate

Accepted provide two main functions of the substrate:

  • masking uneven floor surface;
  • floor insulation.

When performing repair work on the surfaceThere may be some unevenness in the floor. Despite its mandatory leveling before flooring, no one is immune from minor defects. However, household linoleum is soft, and all irregularities will be clearly visible with time, besides, there is a risk of its rupture in these places. Laying the liner under the linoleum allows you to hide these defects and significantly increase the life of the coating.

The second main function of the substrate isfloor insulation. Obviously, linoleum, laid directly on a cement-sand screed, will be cold enough, and walk on this floor is not too comfortable. This is especially significant for the ground floor of a multistory building and private homes in which there is a basement.

It is not enough just to resolve the issue of the need for laying linoleum substrate. It remains to make the right choice of material.

The support under the linoleum: choose

Experts strongly recommendlaid under the linoleum foamed substrate, since it entails a rather sad consequences. Linoleum itself rests on the foam enough smoothly and the operation of it will appear immediately dents, which over time can lead to tearing the floor covering.

linoleum manufacturers are also advised to give upfrom such an option floor insulation. Clearly demonstrated his unsuitability easily. You can take a sheet of plain paper and put it on a hard surface such as a table. Then, push the tip of the knife to the paper. Life experience and a clear example of prompt that the paper does not happen, the maximum - a very small hole appears on her.

However, if a paper to put something relatively soft, even a piece of substrate under the linoleum, and the same with the tip of a knife to put pressure on the sheet, it immediately forms a hole.

Of course, the linoleum is difficult to equate the paper ondegree of fragility, but the analogy is obvious: linoleum is easily susceptible to breakage and mechanical stress. At the same time go on such a linoleum is extremely warm and comfortable. But buying is not the heaviest computer chair can turn a square meter of floor covering in the mess.

Dent on the linoleum

So, to date, experts identified a number of options for the most appropriate substrates under the linoleum. These include:

  • jute fiber;
  • a substrate made of natural flax;
  • a mixture of flax, jute and wool;
  • Fiberboard or plywood;
  • cork maximum rigidity.

Of course, everyone has some kind of substrateadvantages and disadvantages, so you need to make a choice based on the operating conditions of the floor covering, personal preferences and financial capabilities.

Thus, the jute material is ideal forimprove the thermal insulation properties of the linoleum. This is especially significant in cases where the concrete screed was laid directly on the ground or under the house has a basement, which is not heated. The substrate made of jute different environmental friendliness, safety and ability to maintain a favorable microclimate in the premises. However, choosing the jute backing, pay attention to its density - it should be the maximum.

In general, the requirement for stiffness is commonall types of substrates. The fact that with a soft substrate, which is still soft and household linoleum too great probability that the floor will remain unsightly indentations. Moreover, there will be several such floor spring, which does not create comfort during walking. It would seem that in this case, the ideal option would be plywood or fiberboard. However, this opinion is erroneous.

Experienced builders believe plywood inappropriatesubstrate material, as it reduces the lifetime of linoleum. Plywood is more suitable as a support for the wood floor. As for fiberboard, its use is also controversial. This is due to the fact that this material is characterized by good water resistance and resistance to temperature extremes. Of course, this leads to a deformation of the substrate, and as a result, deformation of flooring.

Many experts agree that the best option is cork underlay.

Why is better to plug?

Typically, suberic substrate sold in roll form, which creates a certain convenience when it is laid. By purchasing the material, you need to find out exactly from the seller degree of rigidity.

The popularity is due to its corkperformance characteristics that are provided by its structure. Stopper different cellular structure: in each cell is sealed as an air bubble. This allows the quality to distribute the load on the floor.

Thus, the substrate under the cork linoleum characterized by the following performance characteristics:

  • quality sound insulation;
  • It retains heat, which allows you to walk barefoot on the floor even in extreme cold;
  • water-resistant;
  • It is not conducive to proliferation of mold and other harmful organisms;
  • It protects the floor from damage.

Thus, the answer to the question whether the needthe substrate under the linoleum will be rather positive. It has two, but very important function: masks irregularities of the floor and warms the floor. However, it is worth considering that the choice of a material for it you will have to exercise their own, taking into account some of the nuances: its features, preferences and conditions of use of flooring and substrate.
