Natural linoleum is made from a composition based on linseed oil, containing components only of natural origin: wood and cork flour, ground limestone, mineral pigments, and so on. Coarse-mesh fabric made of natural jute is used as the base. Unlike other types of elastic coatings, natural linoleum has a unique set of properties: antistatic, bactericidal, heat resistance, durability, environmental friendliness, due to which it is used mainly in hospitals, schools, children's institutions, etc., as well as in residential premises. Available in rolls and tiles.
Characteristic features of natural linoleum are the fragility of the coating when bent and the ability to change geometric dimensions depending on climatic conditions. Moreover, while decreasing in the longitudinal direction, in the transverse direction the dimensions of the coating, on the contrary, increase. These material features must be taken into account when laying. In practice, natural linoleum in rolls is laid so that between the panels there is a gap of approximately the thickness of a postcard (0.3-0.5 mm).
Natural linoleum is unstable (flows) before installation, so its rolls are stored only in a vertical position.
The electrostatic flocking method is a new technology for the production of carpets. Short (about 2 mm) polyamide fibers, under the influence of electrostatic forces, are tightly placed on the surface and fused into the polyvinyl chloride base. The result is pile coverings with a pile density 10 times higher than tufted ones and very high strength. Essentially, such coverings are a “hybrid” of carpet and PVC coverings.
Suppose one tile is twice as thick as another, the flexural strength of these tiles will be the same, while the tensile strength of a thinner tile will be 3/4 less than that of a thicker one.
In other words, the tensile strength of a thinner tile will be 4 times less than that of a thicker one.

Joint joints are usually installed between the cladding or covering and other building structural parts, for example, at the junction with a support, window unit or floor threshold.
Criteria for choosing ceramic tiles - molding method
The forming method affects the geometric configuration of the tile. As a rule, it is impossible to achieve such careful control over the surface and dimensions with the extrusion method as with the pressing method. these parameters into account when choosing ceramic tiles.
Extruded tiles should only be laid with open joints. And tiles made by pressing can be laid with both open joints and closed joints.
Why is it necessary to reinforce cement screed or concrete?
First you need to determine why cement coatings are ironed. The fact is that under the influence of gravity, particles of filler (sand, screenings) and cement settle. In this case, the top layer hardens and sets with a high water content, which negatively affects the mechanical strength and resistance to abrasion of the floor. To increase the resistance of the top layer of the floor to abrasion, use iron reinforced cement screed.
I am sure that there are tilers on the forum who do tile laying work. Tell me how much you would agree to do the work on Timofey’s project for. Dimensions, materials, costs and quantities are indicated in this forum thread. We need to build on them.
My price for laying one square meter of tiles is also 600 rubles. The duration of the work is 7-8 days, the price of the work is 25,500 rubles. In this case, you can lay the tiles on a cement-sand mortar. The savings in the cost of the layer will be 3800-3800/4=2850 rubles. If the customer gives 1,500 rubles from this amount, then you can work with the CPR. The duration of the work will be 8-10 days, the price of the work will be 27,000 rubles.
Regarding laying tiles on cement-sand mortar with your own hands. From personal experience I have the following results:
The ratio of components CEMENT M500: SAND: WATER in mass parts should be 1: 5: 0.45;
The thickness of the mortar layer is 7-15 mm depending on the size of the tile;
If the base under the coating has significant unevenness, then it is better to level them first using the CPR and allow to dry;
With a component ratio of 1: 5: 0.45, the solution will slide off the vertical surface, so the tiles on the wall should be laid from bottom to top. At the same time, there is no need to lay more than 4-5 horizontal rows at a time, otherwise the lower rows may form a “belly”;
It is not worth laying ceramic granite on the CPR on the street. The tile will fall off the mortar after a while.
Using porcelain stoneware outdoors is actually not that critical. Indeed, due to low water absorption, there is a risk of the “greenhouse effect”, but this applies to large formats. If you lay porcelain tiles with a format of 30x30 cm, with a 10 mm seam, using suitable adhesive (class C2), then there will be no problems!
As I understand it, he was talking about adhesive milk based on cement, latex additive and water. They need to be mixed in certain proportions. Next, treat the old DSP or concrete base with this milk, and then fill in the leveling screed. The main thing here is to carry out the work “wet on wet” until the milk dries. As a result, the screed will be “welded” to the base.
I used transparent silicone several times to glue decorative ceramic elements. There was an experience of covering a countertop made of chipboard with 10x10 cm tiles; I used transparent silicone as an adhesive, sealed the seams with epoxy grout, and made window trim using an aluminum profile for the edges of the countertops. The result was excellent. This choice of materials was dictated by the customer’s desire to eliminate dust and dirt during the work.
The time required for the mortar to harden (crystallization of cement), dry (relative humidity equilibrium), and then until dimensional stability (end of shrinkage) of the sand-cement mortar is obtained is 1 week (7 days) for each centimeter of thickness . For a 4-centimeter screed, this turns out to be 28 days (about a month).
Thus, the first minus emerged. Perhaps in some cases this point is fundamental, but in my practice, when the thickness of the screed is from 2 centimeters, I use CPR. I use dry mixes in bags only as a finishing coating of thin thickness (self-leveling).
Three weeks ago I worked with the sand concrete M500 dry mix. The cost of a 50 kg bag is now 250 rubles. Continuing Grachik’s calculations, we get: 200 kg will cost 250 * 4 = 1000 rubles. The CPR will be 1000/400=2.5 times cheaper. The mechanical compressive strength after 28 days should be 30 N/mm2 (30 MPa). Like CPR.
It turns out that the price and mechanical compressive strength of the CPR are unrivaled.

Dependence of ultimate strength on thickness
Do I understand this proposal correctly?
In other words, the tensile strength of a thinner tile will be 4 times less than that of a thicker one.

Ceramic tiles can be classified according to the molding method :
