Laying parquet on the mastic

This kind of flooring is made up of individual slats that can be mounted on mastic or nails. In the first case requires strict negvozdimoe base in the second - nailability. Plank flooring in a "Christmas tree" with no freezes and friezes. This flooring is laid on the cold or hot mastic. The base should be of sufficient strength without potholes and cracks. Consider laying flooring in the tree without the frieze on the concrete or cement base or screed. First of all, the base is cleaned of dirt, mortar, dust and other contaminants. Check substrate moisture and air temperature in the room: the air temperature must be below 10 °, relative humidity - below 60% moisture content of cement-sand screed - not more than 6%, intercommunication concrete floors - no more than 4%. Remove any dust and dirt base, check the flatness and levelness tie, if necessary, correct the base, dried and ground. As a reason to stick zvukoteploizolyatsii fibreboard, they are cut out and paste on the hot asphalt mastic and well pripressovyvayut. Can be applied cold bitumen mastic, but it should be waterproof mastic. Fibreboard shall not be continuous and broken edges, the humidity of not more than 12%. First fibreboard dry cut to size. They were then placed on dry ground with gaps between the slabs of 5-6 mm. (This is necessary for expansion boards.) Thereafter plates alternately raised and plank on the hot or cold asphalt mastic. Plate immersed in the paste be careful not to spray it on walls, and well they pripressovyvayut, preferably under prigruzkoy. Usually plate glued in three layers: the first two layers of soft fiberboard type M-20 12 mm, while the upper layer - solid fiberboard grade T-350 or T-400 4 mm thick. Hard boards is sometimes placed on the base in one layer. On a hot plate quicker mastic stick than a cold. This applies to the laying of the parquet. Priming perform primer, ie, liquid paste, which fills all the bumps well and provides a better bonding. Flooring with priming is much stronger than without it. Embossed mastic after laying fiberboards necessarily clean off cycle, or any sharp instrument. Well-glued fiberboard provides reliable heat, soundproofing, and durability of hardwood floor stickers. Depending on the area of ??the premises and the size of parquet planks need to select the optimal and economical performance of work. The length of the bars depends on the width of the room. Well, when you can put the width of the integer series brackets. It is therefore necessary to make a plan laying planks across the room dry (reupload 'Snake'). In the snake (Fig. 37 a) corresponds to the number of each plank flooring. Each row must be placed so that between the walls and the ends of planks was no gap. It is advisable to pick up plates of this size, so you can put a snake of an even number of lattice strips. It must take into account the width of the slats. In strips of width up to 40 mm can not saw off their butts, adjacent to the walls. When the width of the bars over 40 mm gap between the wall and the outermost slats is greater, so the ends of the strips should be cut at an angle of 45 °. If the width of the room fits an odd number of strips of width up to 40 mm, the plank them the same way as for an even number. If the width of planks 40 mm, the snake shift half the length of strap to one of the longitudinal walls. The first series can be installed, perepilivaya one bar of the snake in half at an angle of 45 °. Both extremes are recruited from a number of perepilennyh straps. In this case, being cut fewer slats. If the dimensions do not allow planks to lay out a snake from a number of strips of equal length, then the extreme rows of planks get shorter and broader saw off the ends at an angle of 45 °. Will prepare a plan laying, laid out to begin lighthouse tree (Fig. 37, b).
