Self-leveling floors: base, use variations of the experience of users of the portal

Poured floors are relatively new and do not have time to get the experience of several decades, as traditional concrete screed. But successfully gaining popularity thanks to its performance characteristics, gradually pushing aside more "venerable" category, both in the segment of rough grounds, as well as in decorative finishing segment coatings. Naturally, such an interesting and versatile material could not go unnoticed among the users of the portal FORUMHOUSE.

And the base and finishing

Self-leveling floor - a kind of coupler that forms on the surface of a monolithic, seamless coating to create a samorazravnivayuschiesya used (self-leveling) mixture. As intended it is divided into two categories - the foundation leveling and finishing decorative coating.

Rovnitel

Available in the form of dry mixes, mixable with water. The presence of fillers of small fraction (up to 250 microns), mineral binders and modifiers solution provides ductility and homogeneity. Depending on the manufacturer and application, draft leveling floors can be cement or plaster base.

After solidification forms a solid, wear-resistant, smooth, flat surface, designed for the subsequent lining.

Unlike cement screed obtained elastic, not subject to cracking and shrinkage of the coating. In addition, liquid plasters quickly gaining branded Strength - average 15 days. There are special formulations, solidifying within a few hours.

The thickness of the cast layer depends on the substrate parameters, the lower limit of - 5 mm. Some grades can be filled with a layer of up to 60 mm. Mixtures for alignment used as rough coating under facing laminate, linoleum, tile, flooring, decorative and other self-leveling floors, requiring a perfectly flat base. SNiP permissible difference is 2 mm / m², and allow rovniteli quickly and efficiently prepare the base.

The mixture is selected on the basis of not only the base for the fill data and the necessary thickness, but also in terms of compressive strength of the screed, as different cladding requires different strength. For example, for laminate flooring will fit almost any self-leveling floor, and under the decorative filler based on epoxy - the most durable. Technical premises, which is not always done finish, you should use "Nalivaiko» Industrial strength of 35 MPa, our forum users are aware of this.

Pavlovich P34 (Member FORUMHOUSE):

Under the laminate floor enough strength 8-10 MPa, virtually any suitable filler. A need for epoxide strength of 25 MPa. There is already a high-bulk only can handle.

finishing

Decorative self-leveling floors have all the advantages rovniteley - provide tough, durable, wear-resistant and perfectly smooth coating. But at the same time to an impressive array of features are also an attractive appearance - an imitation of marble, ornate patterns, a combination of contrasting colors, fancy colored mixes, seabed, with three-dimensional effect (3D) and many others.

Although polymer-flooring, intended for leveling the base under the finish sometimes used as surface finish, special decorative self-leveling mix - polymers, which greatly expands the possibilities decorations. On the composition of the polymer floors - one-component or two-component, polyurethane-based or epoxy resins, with builders. And rovniteli, finishing and leveling floors tolerate changes in temperature and heating can therefore be used in the floor heating system. But the maximum temperature at the different formulations, the choice should pay attention to this indicator.

Pour-layer thickness varies from 1 to 8 mm, so to create the decor can be used not only flat but dished elements - coins, shells, pebbles.

Particularly relevant "Nalivaiko" in the terrain areas, technical rooms, bathrooms and kitchens. However, the decorative coating a three-dimensional effect and is able to decorate the hall, and the bedroom and children's room, whether it is proprietary or homemade. 3D self-leveling floor - multi-layer coating comprising:

• base layer - the prepared substrate;
• decorative coating itself - volumetric picture on special paper or fabric-made posters, pictures, drawings, cloth, small ornaments, and the like;
• finishing layer - transparent polymer;
• Protective layer - lacquer.

Self-leveling floor with three-dimensional effect - an expensive pleasure, even if self-assembly, and if hire professionals, the price jumps twice. Polymer floors are simpler, monochromatic, imitating marble or colored with "blots", less expensive, but still - not the most accessible material. However, decorative surface and its durability, subject process compensate costs.

mount technology

Although too much trouble in the self-leveling floor does not create, you must strictly follow the instructions producer, even minor violations can result in the need to dismantle "a rearing" road facing. Installation is carried out in several stages.

Substrate preparation

Depending on the type, liquid mixtures can be used on wood, concrete and MDF substrates after appropriate finishing.

Wooden floor - boards are tested for strength weakened segments are cut and replaced when necessary. Unmounted plinth, scraped previous coating, small cracks are ground to the disclosure, slits are sealed repair mixture. Mandatory checking bases humidity. It should not exceed 10%, or in the future may cause defects. Removes all dirt, dust, wood, degreased if necessary. The last step is carried out surface treatment penetrates deep penetration of the composition. The primer composition will not only provide adhesion to the substrate, but also seals the canvas.

concrete foundation - in the case of repair work, removed the previous coating, the surface is cleaned of dust and debris. If work is carried out on the fresh screed, Gaugeable level cleave protrusions, cracks and potholes are sealed. Since the screed leveling instrument to fill or decorative covering must be not less than 28 days. As in the case with wooden floor, it is necessary to maintain the humidity level of the base, for most compounds require a standard figure of 4%.

VadimXL7 (Member FORUMHOUSE):

Do not neglect the humidity. If you prematurely begin to fill the polymer does not avoid problems. Of course, pay attention to the manufacturer's recommendations. There are materials with a tolerance of 5-12% moisture, and there are vapor-permeable, where the humidity is not regulated (such floor mat). Humidity control is best done hygrometer.

If the hand is not a special device, VadimXL7 It proposes to use a proven method - a piece of plastic the size of 1x1 meters of film. It is glued to the floor on the tape for a day. If after the separation of moisture on the film, or from moisture darkened concrete pouring is delayed until the moment and the film and the concrete will not go dry. Finally, preparation stripped of dust and dirt surface thoroughly primed.

Tile - it does not require dismantling of the entire coating flaking elements sufficiently strengthen and clean the surface from contamination and primed.

In addition to sample preparation, when it comes to pouring a polymer on top of the floor screed or self-leveling rovnitelya, VadimXL7 advises walk sander, at home - conventional grinder with an attachment. This is done to remove the "milk" and reveal the pores, after the surface of the vacuum cleaner and primed.

The choice of a primer depends on the variety of self-leveling floor, which will be poured under the polyurethane floor - and a polyurethane primer under epoxy - epoxy.

When highly porous substrates apply several layers of soil, well-ventilated areas to avoid increased humidity. Primer applied by roller to the base web and a wide brush - in corners and hard to reach places.

To improve sound insulation and prevent adhesion to the walls of the inlet floor, which may lead to deformation of the damper is used feed as when performing dry screed. Its width should be no less than the filling layer, the remains cut off after curing the composition.

mixture

The exact manufacturer's instructions indicate the containers with mixtures. Do not disturb proportions: if exceeding the above amount of water is reduced sex characteristics - both strength and durability. Self-leveling floor does not suffer dilution "by eye", better zamorochitsya with measuring cup, than to spoil the expensive material and its mood. Mixed formulations building mixer. We do not prepare a large amount, since the solution of short term life and you can not catch it develop. A similar situation faced forumchanin IntroCom.

IntroCom (Member FORUMHOUSE):

I have recently flooded the two-component polyurethane floor, got a very nice and hopefully durable. The only negative - a short term solution of life, in the hallway to fill in time, and in the bathroom - no, it happened that ruined half of the mixture. The moral: if section two - should be mixed in proportion, to cast in other containers.

fill

Although pre-aligned base and drops should not be to obtain a perfectly smooth coating level used and beacons. Large area filled by the coating fragments from the far corner, with a move towards the exit. Each serving is poured and leveled with special devices (squeegee), the solution is "stretched" until it reaches the desired level. To remove air bubbles and to prevent blistering, and the mixture is rolled out to the base spiked roller. The dimensions of needles are selected depending on the coating thickness.

Number of pourable layers depends on the species and sex of the desired effect. Drying time for each layer is determined trademark mixture. Setting time, on average, 24 - 48 hours in the room should not be a draft. The last stage is applied to a protective and decorative coating. Alternatively, as a matte finishing the leveling layer is used a mixture which after curing varnish, obtained in description and decorative.

The main enemy of self-leveling floor - damp substrates. If after installing a concrete slab will pull moisture even properly poured coating can swell.

When there is such a risk, it is necessary at the stage of preparation of the basis to take care of additional waterproofing and pouring permeable to use mixtures.

Filler floor and popular as a base layer under the finishing materials, and as a decorative coating, capable of transforming normal outdoor fabric into the seabed, green lawn or dunes. But the cost is covered by an impressive versatility, strength and durability.

On one of the possible grounds for self-leveling floor is told in the article "Dry screed". Rovnitel will help prepare the ground under Infrared Heated floor. Decorative self-leveling floor will be a great base for modern interior materials.  A specialist in our video will show how to make light screedTo prepare the base, including a self-leveling floor.
