wooden floor - it's environmentally friendly, warm and beautiful 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 comfortable to handle, there is always the possibility of the restoration if necessary.But for a long time served as a wooden floor, you must provide the appropriate conditions.Proper waterproofing a wood floor - the main condition for its durability.


floor of wood is different: parquet, wooden and flooring slabs of plywood, particle board, OSB.

To protect the floor from water penetrating applied film and materials for the tree has a porous structure, it can absor

b the moisture and liquid waterproofing materials.The task of waterproofing materials - reliable and continuous protection.The seams, cracks and joints waterproofing material unacceptable, 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 waterproofing floor ↑

  • Okleechnaya;
  • Paint;
  • impregnation;
  • cast.

waterproofing materials Wood banding ↑

Okleechnaya waterproofing is a so-called "carpet" consisting of several layers of bitumen-polymer, polymer and bitumen materials.

Before applying the material required priming the surface.

Paint waterproofing simple and accessible ↑

Waterproofing Paint is a drawing 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 a normal temperature is gradually losing its beneficial properties and requires replacement every 5-6 years.

Protection of wood impregnated ↑

Wood - a porous material.To give the material greater density it is impregnated with special binders.The impregnation can be used as traditional materials - linseed oil, tar or modern - on the basis of silicone, acrylic, synthetic resin.The difficulty is that such infiltration must be applied on a completely dry basis.This method of waterproofing is called impregnation.

Cast method - reliable water barrier ↑

cast waterproofing cost is high, difficult and technical 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 most effective way

layer sheet or roll waterproofing (roofing material, 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 floor in a wooden house ↑

protect wood from the damaging effects of moisture in the wooden house - the most important question, concern with the responsibility for 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, he placed between the wood and the concrete foundation.When

wooden house set on a foundation with a basement, it is also important in laying the foundation to ensure its reliable waterproofing.Waterproofing of the foundation is aimed at preventing the penetration of moisture from the soil.

How to protect the foundation ↑

For this purpose, outside the concrete foundation covered with waterproofing materials - liquid or film.Cellar in this case will be dry, with one source of moisture for the wooden floor less.

front surface or laminate wood flooring is already protected against water, extra waterproofing is not required.But if you have to lay a wooden floor or the floor of the wood-based panels, additional waterproofing is required.Between the floor and the foundation have to be an air space (to the floor was warm).Floor of wood-based panels and placed on a wooden floor joists.Naturally, the space between the foundation and the floor is required to be dry, in order to avoid infection of the tree fungus and mold.Waterproofing of the basement - a prerequisite for the reliable isolation of the wooden cover from moisture.

Depending on the application distinguish antifiltratsionnuyu 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.Depending on the material used can be back-lining, Charging, impregnating, plaster or mounted.Any of the above methods is able to protect the inside of the foundation.

Waterproofing floor on joists ↑

In cases when waterproofing the horizontal surface and the floor can not be installed "on the ground", should be build on the basis of brick columns under logs.Top lags for protection against moisture have to put pieces of roofing felts, roofing felt or polyethylene (make sure that they are larger than the size of columns by 4 cm).Void poured gravel with bitumen impregnation and carefully tamped.

followed by installation of the lag (the wooden structure for flooring or wooden 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 high humidity wood coating can be deformed - "swell", and at a lower - wood tends to crack on the surface can be formed cracks.

for installing lag should be laying a wooden floor.But first you need to take care of hydraulic protection of wood.

possible to apply a polymer or bitumen varnish (the most simple and economical way).We dissolved the bitumen has a useful property - to lay down a solid membrane on the tree, which can grow and shrink with the seasonal strains.A method of applying bitumen or polymer varnish is simple: 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 shade of a tree, improve the permeability between the varnish layer parquet 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 their decorative function.Usually several layers of lacquer provide a dense waterproof shell.

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