So do we need a substrate under the linoleum ?

It is a natural question arising after the purchase of linoleum - is the method of its installation.The choice here is small, because only these two known ways: with or without a substrate.However, even such a poor choice can give rise to many doubts.And to solve them is to understand what kinds of substrates offered in the market, what advantages has every one of them.Along the way, clarified functional features for each species.

First of all, you must understand what the substrate under the linoleum.In fact, it is quite a thin layer of insulation lining between the ground floor and directly linoleum.Therefore, when using the substrate avoids direct contact between the material and the floor.From the descriptions of any type of substrate, it follows that they are intended to perform the following functions:

• defects base compensation;
• soundproofing;
• heat retention.

Types of substrates under the linoleum

grouped under the linoleum substrate, depending on the material for their manufacture: cork, jute and linen, as well as foam.

Cork substrate .Such substrates are under the linoleum sheet of crushed and specially compressed natural cork.The advantages of cork include excellent thermal and sound insulation qualities.However, it is quite expensive and may eventually compacted under the legs of furniture, thus crushing the linoleum.

Jute substrate .For its production of vegetable fibers are used, impregnated with fire retardant to prevent decay and to improve fire protection qualities.As such substrates are valued for their ability to absorb moisture, but after drying completely restore their consumer qualities.

Linen substrate .Such substrates can be two types: pure flax and by braided linen, wool and jute fibers.The first famous for good ventilation, and the latter excellent mechanical strength.

Foam padded .Despite the presence of such substrates in sales and good insulating qualities are laid at home is not worth it, because they are very fast spessovyvayutsya and completely lose their quality.

Selecting a base for laying linoleum.

From recommendations for laying linoleum should be that half the base must have the following qualities:

1. strength;
2. utmost firmness;
3. the lowest possible moisture content;
4. maximum horizontal evenness, ieno height differences.

In addition, the rough floor should be perfectly clean.

Among the types of foundations are suitable for laying linoleum following:

1. Concrete formed hardened concrete mortar or self-leveling screed.Such bases are considered the most suitable for laying linoleum.The only limitation is the need for long drying, which can last up to one month.Ensure complete drying can be laying on concrete polyethylene sheet, if after a few hours it was not formed sweat, the base is ready to start work.
2. Wooden floors.These floors are rarely perfectly straight, so before laying linoleum recommended to sheathe their plywood sheets, becoming a kind of lining under the linoleum.If defects are relatively small, they can be simply putty, dry and sanded.
3. Old linoleum.This embodiment is suitable only when the old linoleum is not damaged and firmly rests on its base.Not allowed laying new linoleum and if the old surface is strongly deformed.
4. Ceramic tile.The basis of the tiles must be previously leveled leveling mortar, dried and tipped sandpaper.To linoleum firmly lying on ceramic tile, it must be degreased before the installation, and carefully sweep the dust.

output.

If the subfloor is completely meet the requirements of manufacturers of linoleum, the use of any additional substrates in order to create a perfectly flat surface is completely meaningless.Furthermore, the structure of the linoleum sheet must include any insulation layers.Accordingly, additional warming of the substrate is also not required.Therefore, any substrate under the linoleum completely useless.The only exception is linoleum without a base, which is just necessary insulation.Also read about what some glue to glue the linoleum.
