We tell about bulk coverage, its varieties, minuses and pros of each type and give useful tips on the choice of material.
The basis for any outdoor decor should be smooth. Otherwise, all base defects will be visible on the finish, which is most likely not served long. Especially for alignment has been developed bulk mixtures. They can be a draft base or a full finish finish. We'll figure it out in the species and tell what the bulk sex choose.

How to choose a composition
Features of the bulk formulations
The base of the material is a self-leveling mixture. Under his own severity, it spreads on the basis, fills defects and irregularities. To make the result, it will be necessary to use simple tools. As a result, a smooth smooth surface remains. Depending on the variety, it can be a draft floor under the tile, laminate or linoleum or finishing finish.
pros
- Fast rejection. The exact time depends on the type of mastic, but on average, it is possible to walk along a flooded surface after 3-4 hours. Bring out the finish finish - after a day.
- Qualitative filling of small defects.
- No shrinkage. This facilitates installation. There is also no need to accurately calculate the consumption of solution.
- High wear resistance and strength. They differ depending on the type of mastic, but in any case the surface is well resistive to wear and withstands significant loads.
Minuses
- Fast setting. The liquid solution is collected in minutes. It is extremely difficult to correct some shortcomings, and after the surface has gripped, it is impossible.
- Small fill thickness. Therefore, the foundation needs to be carefully prepared. Only small defects are allowed, the large closure will not succeed.
The minuses include a high price. Bulk masts are unprofitable to level significant curvatures on large areas. In this case, first put the screed, on top of which the bulk floor is mounted. So get the perfect base for any flooring.
Types of bulk floors
We will understand the features of each option.Cement mixes
Dry cement formulations. The filler uses a small stone crumb or quartz sand. Plasticizers and other additives are necessarily added, which make the solution to fluctuate and give a rapid grasp. Before the operation of the mixture is bred by water. The proportions specified in the instructions must be strictly observed, otherwise quality suffers.
Cement solutions are universal. They are used in premises and for external work. They are very durable, moisture resistant, durable, have high adhesion to most materials. It can be poured with a layer of different thickness: from a few millimeters to 6-8 cm. That is, if necessary, you can get a full-fledged tie. From the disadvantages it is necessary to mark a small shrinkage, while cracking does not occur. Formulations are resistant to the formation of cracks.
Resistance to aggressive acids is low, cement base should be preserved from such an impact. A minus is also a long set of operational strength. Other modifications take it much less time. The main area of the use of cement compositions is the base for further finish. Sometimes they are used as an finishing coating. But this is only in cases where decorative sizes are not required. Still, the appearance of the cement floor is not the most attractive.
Gypsum (anhydride) solutions
The base of the composition is a gypsum powder. Additionally, fillers and plasticizers are used. As a result, a completely eco-friendly coating is obtained compatible with any warm floor system. The average stacking thickness is 5-10 mm, but there are brands that can be laid even a higher layer. The gypsum surface is well kept sound and heat, capable of adjusting the humidity and quickly hardened. At the same time, its strength is lower than that of cement. She is inferior to moisture resistance. For these reasons, the gypsum level is used only in dry rooms and only for alignment, as the base under the finishing decor. It is desirable that the load on the plaster base be small. The solution is harden quickly, which is not always good. It is also easy to lay it and right. Alterations are impossible.
There are combined compounds based on cement and gypsum. They are characterized by the advantages of both varieties, but their shortcomings are eliminated. The mixtures are placed in the premises of any humidity, they are not suitable for exterior work.
Polymer mastic
Compositions based on synthetic polymers are designed for finishing finish. At the same time, they also hide small base defects. This is one- or two-component liquid pastes that are sold in ready-to-fill form. The price of them is significantly higher than gypsum or cement solutions. The properties of the polymer coating depends on the form of the basis. To determine for yourself, what kind of bulk sex is better, we will analyze the pros and cons of sought-after options.Epoxy
They are manufactured on the basis of epoxy resins with the addition of hardeners, fillers and other components. They are very durable and rigid, withstand significant loads, resistant to abrasion, insensitive to temperature drops. Moistureproof, do not spoil from the effects of household chemicals and most of the aggressive substances of the type of acid or alkali. A smooth surface does not absorb dirt, easily ished.
The main minus epoxy mastic is low elasticity and fragility after a fold. When a severe item falls, the likelihood of damage is very high. Therefore, it is not worth mounting it where there are shock loads. The best place for it is wet rooms, although you can use in any room, including children.
Polyurethane
Produced on the basis of polyurethane or artificial rubber, so very elastic. They are resistant to mechanical damage and aggressive substances. High moisture resistance allows the use of polyurethane mixtures in wet rooms. This is one of the best solutions in the question of which bulk sex is better to choose for a bathroom or bathroom. It is possible to put it in the kitchen, since the temperature changes are also not terrible to him.
Polyurethane Durable and durable, gives additional noise and thermal insulation, is easily clean. The finished surface, depending on the mixture, can be glossy or matte, many design options. With random damage, the defect can be corrected: the area is sandwiched and covered with a special varnish.
The disadvantage of the material is the complex installation and disassembly.
Methyl methacrylate
These varieties are used mainly to fill the floors in industrial premises. Different with increased resistance to aggressive chemistry, moisture resistance and durability. Very quickly collapse, hardened for an hour, after one and a half or two by this floor can be walking. Wear resistance is higher than that of polyurethane.
The main disadvantages are the complexity of laying and an unpleasant sharp smell in the process of rejection. Options for registration of methyl methacrylate coatings are very small.
To solve the issue, which self-leveling bulk sex is better, it is necessary to determine the purpose of the fill. So, if you need a base for decorative cladding, a gypsum or cement solution is suitable. The finish decor can be one of the modifications of polymer mastic.
How to choose a bulk sex
The choice is determined by the operating conditions of the coating. For residential rooms, any mineral mixtures are suitable. It is necessary only to take into account the humidity of the room. You can choose polyurethane or epoxy mastic, especially since there are many options for their colors and design. It can be imitation of marble, granite and other stone or a transparent floor with minor items. Painting paint paint or without it is possible or spectacular 3D design.
If in the bathroom, bathroom, in the kitchen, in the hallway it is planned to finish with tiles or linoleum, choose compounds based on cement. A seamless polymer coating of any type is suitable. Important moment. If laying of a warm floor is assumed, the coating compatible with it is selected. This is indicated on the packaging of the composition. Another significant nuance is the type of foundation. On a flat concrete slab can be laid any material. In other cases, the fill may be required to lay a floating screed.
