How best to make waterproofing the wooden floor

Wooden floor - is environmentally friendly, warm andbeautiful appearance. After all wood - a natural material with a mass of useful features: a low thermal conductivity, good insulation, beautiful texture. The wooden floor is convenient in handling, there is always the possibility of the restoration if necessary. But for a long time served as a wooden floor, it is necessary to provide appropriate working conditions. Proper waterproofing a wood floor - the main condition for its durability.

Floor of wood is different: parquet, plank, flooring and plywood boards, chipboard, hardboard, OSB.

To protect the floor from water usedFilm and penetration materials, because wood has a porous structure, it is able to absorb a moisture and liquid waterproofing materials. The problem of waterproofing materials - reliable and continuous protection. The seams, gaps and joints waterproofing material inadmissible, because in the event that the water floor will simply rot. In places where the floor is in contact with the wall, waterproofing is not interrupted - to a height of 30 cm from the floor necessarily applying a protective layer.

Classification of waterproofing the floor

  • Okleechnaya;
  • Paint;
  • impregnation;
  • cast.
Okleechnaya floor waterproofing

Wood banding waterproofing materials

Lining hydraulic seals is the so-called "carpet" consisting of several layers of bitumen-polymer, polymer and bitumen materials.

Before applying the material required pre-primed surface.

Paint waterproofing simple and affordable

Waterproofing Paint is adrawing on the wooden floor several layers of bitumen or polymer coatings. This method is available and easy to implement, but has the disadvantage - low temperature in a room in the protective layer cracks. Paint waterproofing short-lived, even at normal temperature is gradually losing its beneficial properties and needs to be updated every 5-6 years.

Paint waterproofing "closes" wood pores, preventing the penetration of moisture

Protection of wood impregnation

Wood - a porous material. To give the material greater density it is impregnated with special binders. The impregnation may be used as conventional materials - linseed oil, tar or contemporary - a silicone-based, acrylic, synthetic resins. The difficulty is that such impregnation should be applied on a completely dry basis. This method of waterproofing called impregnation.

Cast method - reliable water barrier

Cost cast waterproofing is high, it is difficult andtechnical performance. But it is quality performance cast waterproofing will protect the wooden floor from many problems for a long time. Let us consider the technology to create a cast waterproofing.

Waterproofing of the foundations

Cast waterproofing floor - expensive, but the most effective way

A layer of waterproofing sheet or roll(Roofing felt, gidrostekloizol or other waterproofing materials, reinforced polyester or fiberglass) is placed on pogruntovannoe and properly prepared substrate. Sheet or roll waterproofing can be surfaced using a gas burner or glued by a cold. After the installation is done waterproofing screed cement mortar with the addition of water glass. Screed reinforced with a metal grid. The surface thus obtained is coated with an extra layer of waterproofing - waterproof cement-based composition. For extra strength (waterproofing layer is extremely resistant to abrasion) on the surface after drying should be spread out a special substrate under the wooden floor.

Waterproofing of the floor in a wooden house

Wood protection from the damaging effectsmoisture in the wooden house - the most important question, take responsibly to the choice of waterproofing material and quality work. If the wooden building is not a basement, then as a waterproofing material can be used roofing material or roofing felt, it is placed between the wood and the concrete foundation.

When the wooden house set on a foundation with a basement, it is important even when laying the foundation to ensure its reliable waterproofing. Waterproofing of the basement It aims to prevent the penetration of moisture from the soil.

How to protect the foundation

foundation hydroprotection

Waterproofing of the basement foundation and protects the floor from ground water

To this end, the outside is covered with a concrete foundation waterproofing materials - liquid or film. Basement in this case will be dry, with one source of moisture for the wooden floor less.

The front surface of the floorboard or laminatealready protected from exposure to water, an additional waterproofing is not required. But if you have to lay a wooden floor or a floor of wood-based panels, additional waterproofing is required. Between the floor and the foundation have to be an air space (so that the floor was warm). Floor of wood-based panels and a wooden floor is laid on logs. Naturally, the space between the foundation and the floor have to be dry to prevent infection by fungi and wood mold. Waterproofing of the basement - a prerequisite for the reliable isolation of the wooden cover from moisture.

Depending on the application distinguishantifiltratsionnuyu basement waterproofing (protection of ground water) and corrosion waterproofing. Antifiltratsionnaya suitable for waterproofing basements, as well as for areas with high moisture aggression, as well as increased pressure load. Corrosion insulation of the foundation necessarily used in all other cases. As can be back-lining, Charging, impregnating, plaster or mounted, depending on the material used. Any of the above methods is able to protect the foundation from the inside.

Waterproofing floor on joists

In cases where the waterproofing of horizontalthe surface of the floor and can not be installed "on the ground", should be to build on the basis of brick columns under the joists. Top to protect from moisture lags need to put pieces of roofing felts, roofing paper or polyethylene (make sure that they are larger than the size of columns by 4 cm). Void is filled with gravel with bitumen impregnation and carefully tamped.

The following log installation (wooden structure,designed for flooring wooden floors or floors made of wood-based panels). Important! - Logs must be thoroughly dried (humidity not more than 12%) and processed antiseptic. During the work on the flooring wood flooring the room temperature should not be below + 70 ° C, and the humidity should not exceed 50-60%. When the air humidity wood coating can be deformed - "swell", and at a lower - tree has a property to crack, the crack can be formed on the surface.

During the installation of the lag should be laying a wooden floor. But we must first take care of hydraulic protection of wood.

You can apply a polymer or bitumen varnish(The simplest and most economical way). We dissolved the bitumen has a useful feature - to lay down a solid membrane on the tree, which can shrink and expand with seasonal strains. A method of applying bitumen or polymer varnish is simple: by using painting tools - rollers, hammers finishing brushes, sprayers. The resulting protective layer in addition to its durability and water resistance has also insulating properties, which is important.

Priming paints give a particular shadewood, improve permeability between the layer parquet lacquer and wooden surface, and also serve as waterproofing the wooden floor. The impregnation of the upper layers of primer paint wood fibers contribute to bonding of fibers that gives the hardwood floor an additional impact. Different stains for wood, besides imparting color saturation and sharpness, also contribute to the prevention of surface moisture. Parquet varnishes also serve as an additional waterproofing, in addition to its decorative features. Usually several layers of lacquer provide a tight waterproof shell.

Wood - very sensitive to changesClimate material, particularly sensitive to temperature changes, as well as to changes in room humidity indicators. It is not only possible deformation of the material: wet wood is a beneficial environment for the development of mold and mildew that cause a variety of chronic diseases and allergic reactions in the house inhabitants. To prevent an unpleasant prospect, it is important to organize a set of measures to protect the wooden floor from moisture.
