Linoleum, wooden parquet, laminate and different types of tile – tile, ceramics, porcelain tile are considered as the most usual finishing floor materials. Many of us beginning repair in own apartment, wish to receive unique interior of the room on the end of all works. At the same time a little already whom you will surprise with above-mentioned materials, and such material as marble or granite to not everyone on pocket. However nevertheless there is opportunity to execute exclusive finishing of floor cheap and rather quickly if as floor covering to choose pith floor.
What is pith floor?
Pith floor is made of panels which main raw materials for production, is the stopper. At once it is necessary to tell that the stopper is not type of wood and even not breed of tree. The stopper is prepared from top layer of bark of pith oak of the Mediterranean growing in the western part. For this reason the most qualitative floor coverings are made in the European countries. The fact that at preparation of pith raw materials deforestation is not made is interesting. From century pith oak cyclically each 6-9 years make removal of bark from the main trunk. In further raw materials dry, process, split up and make by pressing method finish coats, different on function.
It is a little about advantages of pith floors
The main advantage is attractive and original exterior. Yes, it is impossible to surprise someone porcelain tile today, but the pith covering is considered the true exotic.
In addition to original exterior pith covering have number of the following merits:
- Good elasticity and depreciation of surface;
- Reduction in sound level and sound insulation of floor;
- Additional heat insulation of floor;
- Water tightness;
- Available cost of material.
There are three main types of pith coverings:
- Solid Veneer panels – are characteristic availability on face side of thin integral cut of bark of pith oak.
- The mixed look – at front layer there are elements of integral interline interval and natural granulated cork.
- Agglomerate – front layer is executed only from the crumb applied on the dense basis. The front layer from crumb can be covered depending on model 1-2 with varnish coats or vinyl film.
On mounting mode pith floors are glued and castle. Castle pith floors are more acceptable for mounting in premises. In turn the glued pith coverings are suitable both for inhabited and for public places, for example for finishing of floor at office.
Mounting mode of the glued pith covering
For mounting of pith covering on glue, it is initially necessary to prepare floor surface. Mounting can be made on carefully leveled concrete bed in which there are no roughnesses. The concrete surface has to be equal as glass, and the admissible difference of floor can make 2 mm by 1 m. To achieve such surface, it is possible to make over concrete bed thin sand-cement screed without finish. Solution for tie is done intentionally liquid and flexible due to introduction to it of special plasticizers. There is also other way to prepare surface for mounting of pith covering. To level uneven concrete tie over it it is possible to make mounting of sheet hardboard or thick moisture resistant plywood. The hardboard is mounted on glue mix on the basis of bitumen, and mounting of plywood can be executed often located anchors.
Having prepared surface, on its plane make marking. Pith panels for gluing I make standard dimensions 30×30 cm, 30×60 cm and 45×45 cm. And it is optional to carry out mounting of integral panels. Thanks to easy processing from pith panels it is possible to create magnificent ornament. For example, the surface of floor can be differentiated asymmetrically, having mounted on one plane of the panel, differing on color and tonality. If mounting of panels of one tone is made, then the marking is begun with definition of the center of the room. For this purpose between opposite corners on the diagonal of the room pull thread. On thread carry out marks, then across mark thread on diagonal between the second couple of opposite corners stretches.
Having found the exact center of floor, from this mark at an angle 90 ° on the plane of floor spread densely to each other pith panels in the direction of each of four walls. Having laid out in each direction of the panel, make their shift so that between edge of the panel and wall there was gap of 4-5 mm. Further on the received marks strictly parallel to walls on the sexual basis draw base lines which will serve as reference point. It is more convenient to put base lines by means of fender marker thread.
At the following stage start gluing of pith panels, beginning on the most distant base line and gradually moving ahead to outer door. Apply special contact adhesive on the basis of polychloroprene (kind of rubber) to mounting of pith covering or latex acrylic. Initially glue is applied by means of the small palette on the sexual basis, stretches the palette comb for receiving uniform layer. After that glue is similarly applied on rear side of cork board. Further it is necessary to wait for from 5 to 20 minutes still applied glue will not begin to harden slightly and at this moment the pith covering is put to the basis processed by glue and slightly pressed. It is necessary to tell that glue applied on stopper rear side for several minutes will quicker harden, than glue on surface of concrete tie or plywood leaf. For this reason the above described sequence is also made.
After laying on glue of the pith panel on its plane leveling instrument is established horizontally and, as far as possible level horizontal position of the panel. However when leveling it is necessary to be careful if strongly to press on plate it is possible to squeeze out in whole or in part from under plate contact adhesive that, of course, will affect bad quality of mounting. The excesses of glue acting from seam between the next tiles should be deleted at once accurately with the palette, and the seam can be wiped with rags slightly the wetted in White Spirit. After mounting of panels on all plane of floor, it is possible to move on them not earlier than in 48 hours. When glue finally dries, start mounting of plinths. When mounting wooden plinth it cannot be beaten to pith covering at all, mounting is carried out only to wall.
Way of laying of pith covering with lock connection
This way is very similar to laminate mounting. It is initially necessary to prepare surface, having made equal tie. If differences of draft floor not too strong and on its surface are absent strong defects, alignment of surface can be executed the self-leveled bulk tie. Having leveled surface, on all its area the polyethylene substrate is dimmed. The overlap between strips of substrate has to make 25-30. For motionless fixing of strips of substrate the normal wide adhesive tape is used. One more important condition, substrate there has to be a little more than the area of the room and find on surface of each wall on 5-8 mm.
Before stacking pith panels, it is necessary to decide on their direction. The best visual effect can achieve if to arrange panels in the direction from window to the opposite side of the room. In this case the effect of integrity of all floor covering will be created. Having decided on the direction, on transition of wall with floor from where laying will be made, establish wedges. These wedges will provide optimum gap between the first row of panels and wall.
Before beginning to stack the first row, one pith panel is sawn exactly on two parts. Begin laying about 1/2 panels with the far left corner. Having laid out the first row of panels, the second row is begun with the integral panel, the additional sheaf thereby is provided. Connection between panels among carries out at the expense of the thorns entering grooves and forming strength lock connection. For this purpose in the beginning one row consisting of several panels gathers completely, then its end face with thorn is established at an angle in 45 ° in groove of the laid previous row and, making weak emphasis forward and down, lock connection fixes both rows.
Apparently, this mounting mode of pith panels simpler, however it has several shortcomings. Mainly floor has the worst water-repellent properties less long term of operation. The way of laying by lock connection most often is applied in such rooms as the bedroom or the nursery.
