Guide to the bathroom waterproofing: prevent the negative influence of water

Guide to the bathroom waterproofing

Specifics of operation dictates bathroomneed to optimize the performance of waterproofing. The room, designed for hygiene, high level of humidity. Deposited on the surface condensation contributes to the destruction of building materials. The vapor penetrating through the wall adjacent to the bath, may damage the finish. Need waterproofing bathroom is also in order to avoid the Gulf of living downstairs neighbors in the event of accidental leaks. Summing up the arguments in favor of waterproofing is easy to conclude - these activities much more economical cost to restore a strange and personal property, tainted water and steam.

For the application protects against impactcondensate and water bed industry offers a wide range of products. There are a number of ways, the implementation of which is only available to experienced professionals, equipped with special equipment. However, perfectly working waterproofing can make any host that does not have a repair skills. Only need to correctly pick the material, to determine the scope of work, to study the implementation of technology, patience and the necessary tools.

We plan that will isolate

The preliminary stage of any work requiringpackage material costs should be planning. You do not need drafting enough scheme with accurate dimensions bathroom. Well-designed area, intended for the treatment, will minimize costs, excluding acquisition surplus.

There is no question that in the plane of the floorthe bathroom is necessary to protect the relevant layer. If it is intended only waterproofing material laying on the floor, it is desirable that the walls of the bottom 20 cm were also protected against moisture by the same layer. Waterproofing in these cases resembles a kind of container that prevents ingress of waste water in the overlap area and bathrooms neighbor living downstairs.

If the landlord concerned about securitywalls, adjacent to the sanitary room, combined construction plane should be treated the same. Waterproofing also applied to wall surfaces, which are installed near the showers and other plumbing fixtures.

The range of waterproofing materials

The difference in methods of application layer,preventing the entry of moisture, it determined the division of the whole range of waterproofing materials on Wood banding and more popular now obmazochnye compositions. Pasting or obmazochnuyu technology chosen, focusing on the preferred landlord to timetables and surface characteristics, intended for processing.

Pros and cons of back-lining materials

The most well-known, proven methodwaterproofing bathrooms were applying to the surface of the roll material, the main component of which is bitumen. Delivered in our time to market, roll, polymer products are modified by the introduction of components reinforced with glass fibers or other synthetic fabrics. Among the materials with reinforcing the foundation of self-adhesive and have a variety of fusing. stacking technology waterproofing layer, the deposited on the surface, too complex for a beginner and is impossible without the use of special burners. Because wishing to save time and facilitate the production of works inexperienced performers prefer to adhesive options.

Recognized decorators and builderspositive qualities roll waterproofing considered ease of self-adhesive insulating layer, the reduction of technological terms. Made using rolled materials waterproofing the floor in the bathroom does not require waiting hardening the surface, allowing you to start without delay finishing works: laying tile, linoleum, granite. A significant plus - a clear adhesive fixation modifications. They do not move and do not spoil on the movement of people on the laid surface.

Materials for waterproofing bathroom, supplied in rolls

Roll materials with a bitumen basis, intended for waterproofing rooms with high humidity levels

Negative side waterproofing roll pasting:

  • the need for preliminary surface alignment as unevenness exceeding 2 mm is not permitted;
  • base, designed to handle, must be dried;
  • presence of sharp toxic smell of bitumen, not "erode" extended period.

If, focusing on speed of execution, the owner of the premises with a flattened surface is still choose the way of pasting, it is recommended to prefer self-adhesive versions of waterproofing materials.

Features of surface waterproofing

Unpretentious generic formulations do not obmazochnyerequire careful surface preparation prior to application as in a certain extent themselves function as a leveling layer. For those who do not spend time on preliminary preparation of surface waterproofing - the best choice. This category of materials more expensive kraftliner counterparts, but given the lack of need to buy the leveling mixture, it is acceptable and even economical.

Of coating compositions are presented:

  • bitumen-polymer mastic with the basis of oxidized bitumen and the inclusion of an organic solvent;
  • Bituminous-rubber mastics, enriched increases the elasticity of synthetic fillers;
  • cement-polymeric mastics, is a mixture of cement with mineral additives.

Please be aware that if the waterproofing in floorthe bathroom was performed with the use of mastic asphalt with the main component, it is required screed. This scheme is completely prevent the penetration of moisture. But in order to tie after shrinkage cracks were not, in the need to add fiber of polypropylene. The modifying component is to strengthen the concrete base.

Of coating materials are excellentadhesion to the treated surface. The presence of inclusions plasticizing improves work with any rigid foundation. Priorities processing mastics concrete structures due to the maximum penetration of the compositions into the concrete structure and the formation of new crystalline stronger ties. Created with the help of the components of mastic prevent the formation of crystalline water, but breathable.

The calculation of the amount of material

Once I decided on the next artistFront work, find out what plane it will process and chose the material, you will need to calculate the required amount of coating of mastic, roll waterproofing materials, or both in the case of sharing. To calculate the material needs is an elementary formula - treated surface area is divided into a kind of a factor of 1.5. Round off the result to be in a big way. For the application of the impregnation or laying a layer only on the floor main parameter that will need to be divided, will floor space. Do not forget that 20 cm of the walls around the perimeter, too, it is desirable to isolate. Similarly calculated demand for self-adhesive materials for walls or segments of vertical surfaces.

The preparatory phase of the work

Regardless of the choice of material and methodstarting step waterproofing should be to prepare the surface for subsequent processing. All planned to spray plane materials must be cleaned of dirt, worn coatings, traces of mineral oil and fat-containing compositions.

To waterproofing bathroom with their hands was effective, you need to pay attention to the nuances of the following:

  • before fixing roll spacer on the wall or laying it on the floor should conduct alignment before applying the mastic these measures are not necessary;
  • concrete surface must be sanded, remove the weak layer, the so-called "concrete milk" hold rasshivku damage and cracks, repair them with special formulations;
  • concrete waterproofing prior to moisturize, but the floor is not permitted accumulation of excess water.

In order to generate the maximum insulationeffect it is recommended to conduct additional insulation abutting structural components and joints between the elements. For this purpose, the joints do not indent depth of 3 cm, which must be filled with a special solution. A more affordable way - taping joints with insulation tape.

On abutment structural elements need to paste special tape

The essential recommendation: before applying any waterproofing material must be treated with the rough surface of primer for adhesion optimization. Perfectly paired with the insulating material of coating composition is a primer of the same class. Those wishing to make a bathroom insulation with a roll of self-adhesive materials should be preferred formulations are compatible with the base, you can simply cover the surface waterproofing paint. The ground in front of the production of further work should be dry.

Application of surface waterproofing

Among the market of coatingmaterials have prepared to spray compositions and dry mixes for the preparation of which is necessary to carefully examine the manufacturer's instructions and keep all items listed in the instruction. Cook or do yourself a homogeneous mixture is applied with a flat brush, roller or special construction spatula, evenly distributed over the surface of coating material. If the manufacturer recommends multiple application of each subsequent layer is directed "to cross" the previous. Between coats you need to follow the manufacturer specified interval required for complete solidification. Not less than one day must elapse after the processing of coating materials, after which it will be possible to proceed to the wall.

Self-adhesive insulation and other methods

All work is to discover and fixwaterproofing material. Form laid on the floor layer should resemble a trough. The final phase - treatment of sealant joints having a silicone base.

The owners, a puzzled question "how to makewaterproofing in the bathroom the most cheap "repairmen advise cover the surface of the elementary composition of the coloring waterproofing, prevent the entry of vapor and moisture. Cast option is not advised, it is effective, but difficult for self-fulfillment. Loose-fill insulation layer will be too powerful and not particularly effective.

Ways to improve waterproofingcharacteristics of the bathroom, available for self-fulfillment, not too much but enough to choose from. there are notable differences between them. What is more important for the owner: speed or cost? Deciding he would be alone, and after reviewing the specifics of works will be much easier to make an intelligent decision.
