Laying of the laminated parquet – business quite simple and not demanding special skills. Accuracy, accuracy and patience – the main guarantors of high-quality laying. The main condition is the condition of surface on which laminate will be laid. 90% of the problems arising afterwards come from incorrectly prepared basis. The substrate on which many aspects of operation depend also gets to this category. In this article we will try to consider all nuances of installation of floor covering of this type.
Preparation of different types of the basis
The main requirement to the prepared floor – ideal flatness. There should not be deflections and hillocks. The concept “smoothly-means exactly” is no good at all. In these parts there will be deformation of connections that will cause separation of locks and, respectively, their breakdown. In critical cases it is possible to fill deflections with several layers of substrate, but it is not panacea. Over time the substrate will sink, and the problem will appear again. Smoothing of hillocks will lead in the similar way only to emergence of other problem: to basis bend. Basis “propellernost” is especially carefully checked. The opposite sides have to be strict in one plane. Non-compliance with it is fraught with constant scratch of floor and gradual destruction of locks. The squandered corners or curvature of the basis are not admissible. The laminated parquet will be thicker and more rigid, the stronger it will respond. Dot loading in one corner (example: the heavy sofa), will cause wave on all floor and raising of parquet in opposite corner.
Preparation of concrete bed
Concreting of floors is made on level, but the surface cannot just be made ideal. For this purpose there are several ways and wide choice of materials. Use of the bulk leveling solution (floor) can seem to the simplest. There is one problem: for its correct application experience and skill are necessary. Otherwise the result will be negative. As it is meant that there are no special skills, it is better to go some other way. By the way, the most economical.
First: leveling of floor height is carefully made. It can be done by means of hydrolevel or the laser, self-leveled level. For simplification of the subsequent operations, it is desirable to mark on line walls, according to level marks.
Further beacons are established. It is possible to use, both special beacons, and various products from the pro-thinned-out tin, like the directing UD for gypsum cardboard. Beacons are established in parallel, at distance of one meter from each other. At bigger distance it is more difficult to level the surface of filling. The ends of beacons are fixed near walls, precisely on marking. Then, by means of improvised materials (supports), the horizontal line of each beacon separately is exposed. It can be done with use of cord or if width of the room is small, by means of the rule. Length of the rule has to be a little less width of the room. After that beacons accurately are fixed on floor by cement of plaster. Plaster support have through 30 cm from each other. When plaster stiffens, supports clean up and it is possible to start filling.
For filling cement and sand solution is used. Proportions depend on the brand and quality of cement. Ready solution has to be smoothed with the palette rather easily. Filling is made in turn, in each compartment formed by beacons. After filling of the next compartment, solution stretches by means of the rule. The rule is put by sharp edge on two parallel beacons and accurately stretched on all length, removing excesses of solution and filling holes. Especially accurately it is necessary to remove collected solution near walls. The left flows should be forced down then the perforator. This operation becomes several times until the rule ceases to collect solution. After the end of filling, floor is left before full drying of tie. The term of endurance is defined proceeding from the maximum thickness of the filled-in layer. About one week on one centimeter.
After drying of tie final alignment of surface is made. Now it is quite possible to use bulk floor. He gets divorced to rather liquid state and has to spread, without forming hillocks. With its help the main defect of simple cement slurry – shrinkage capacity is eliminated. Mix prepares by means of the mixer in any suitable capacity. The further procedure is completely identical previous, with that small difference that smoothing of bulk floor should be done quickly as the survivability of ready solution is short. Subsided mix will try to keep step with the rule and it cannot be leveled.
Preparation of the wooden basis
Flooring of wooden floor, is separate subject, and we will recognize that it already is. Under the laminated parquet it is required to lay the equal basis from plywood or RSD. Respectively, beating of level and assessment of flatness of floor will be the first step. If surface rather equal, then material it is possible to use 12 – 15 mm thick. Otherwise thickness should be increased, for exception of possibility of bowing. Economy, in this case, will lead to fast failure of laminate. New floor is, as a rule, laid on level and its preparation is insignificant. It is only necessary to remove plane differences on joints of boards and it is possible to fasten the basis.
Preparation of the old, deformed floor process more labor-consuming. Let’s begin with the fact that on level the double perimeter beats off. The upper line – the level of future covering, lower – the level of the leveling linings. The distance between lines is equal to basis material thickness. For simplification of task it is better to fasten rail on all perimeter of the room, at the level of the lower line. Further, by means of the rule (the cord is no good), we begin to fill deflections with linings. The rule leans the ends on rail and under it is palmed off, gathered to the necessary thickness, lining which, then, is fastened by self-tapping screws to floor boards. After fastening height of lining is again checked and, if necessary, it is added still. At very big failures, over two centimeters, are reasonable to use integral boards. For exact adjustment it is possible to use dense fibreboard. It is easily stratified to the necessary thickness and has sufficient durability. The quantity of linings on the area is unlimited, the their is more, the better. It is desirable to have them in certain order afterwards more precisely to fix basis self-tapping screws. After laying of plywood or RSD, joints of plates processed by the grinder. By the way, some producers of the laminated parquet recommend to lay plywood and on concrete bed though it is reasonable only at parquetry from wood array.
Choice of substrate
The range of substrates, in our shops, is limited, generally to stopper and, different thickness, frothed polyethylene. Unfair sellers say that these materials differ only in degree of environmental friendliness and will level any surface. No, and once again not. Stopper very strong and wearproof material which is fine heater. It is absolutely safe from ecology, but it requires really ideal basis. Frothed polyethylene, in turn, is intended for compensation of small differences and the acting grains of sand or crushed stone. Its basic purpose – sound insulation. What bigger thickness will be substrate from frothed polyethylene, more package floor will remind those the Persian carpet the softness. On heat insulation it concedes to pith substrate. The optimum substrate should not be more than three mm thick.
One of the main conditions of durability of the laminated parquet is the good waterproofing. Polyethylene foam
himself is the wonderful hydroisolation center, and here under stopper it is better to lay protective film, despite of the fact that many types of laminate are issued on the basis of waterproof MDF.
What it is necessary to pay attention when choosing of the laminated parquet to
The choice of the laminated parquet completely depends on esthetic requirements and financial opportunities. Therefore only several councils how to make right choice:
- The first: it is necessary to give preference in any price range to laminate of bigger class of wear resistance.
- The second: do not hesitate to check quality of plates in the sealed packagings. It is enough to verify the lot number and to open one box for verification with sample on show-window. Sometimes comparison can unpleasantly surprise.
- The third: carefully examine plate of the bought parquet. On edge of the laminated party should not be having chopped off. If they are, then it testifies to low-quality film or processing by blunt tool. Both inadmissibly.
- The fourth: pay special attention to quality of milling of locks. In corners, on transition of the same party of the lock to other party of plate, there should not be differences. The line of milling has to be equal, without steps. Otherwise, when snapping the lock, it will break, and parquet hoards will disperse.
There are several main types of locks for parquet. Producers constantly experiment with them. Some simplify, others, on the contrary, complicate. Therefore it is impossible to tell precisely that this parquet is mounted so, and this here so. For this purpose, very available mounting instruction is enclosed in each packaging. Exact following to it – quality assurance.
