Natural linoleum - advantages and disadvantages
The benefits of this linoleum, in addition to environmental friendliness, include a long service life, high strength and durability. Thanks to linseed oil, it has bactericidal properties, antistatic, neutral to household chemicals and is very resistant to aggressive environments, almost non-combustible and, in addition, unlike ordinary linoleum, does not melt from the touch of smoldering cigarettes.
In its turn, the disadvantages of this material are high price, inability to use in damp and unheated rooms, it requires a very careful attitude when laying, due to the high fragility of the material when it is bent.
Laying of natural linoleum - preparatory work for
For the high-quality laying of natural linoleum, must be carefully prepared , as the specificity of this coating requires increased requirements for its strength and smoothness. In addition, the substrate must be clean, dry, absorbing moisture( due to the specific properties of the adhesive that is used to lay this coating).In most cases, to achieve these conditions, surface preparation is carried out using self-leveling mixtures.
For the laying of the coating, the following tools will be needed: roulette, industrial hair dryer, notched trowel, linoleum rolling roller, cutting knife, combo scraper, sickle knife, vacuum cleaner.
Begin laying - features and practical advice
The laying of natural linoleum should be done with the utmost care, preferably with the efforts of two people. Preliminarily the material, for acclimatization, must be kept in a room where it will be laid during a day in an upright position. It is also necessary to rewind rolls with the front surface inside( to reduce the longitudinal shrinkage when using water-dispersible glue).
Cut out sheets of natural linoleum according to the size of the room, paying attention to the fact that the direction of placement marked on the back of the rolls by the arrows coincided.
For a smooth cutting line, you can use the plaster rule. The edges at the joints should go 2 cm apart to compensate for the unevenness of the base.
After that, open the container with a special water-dispersible glue and mix it thoroughly. Then, with toothed , apply glue on prepared base at the rate of 250 g / m2.Glue the cover with strips, for which the glue is applied to 5-10 cm more than their overall dimensions.
We continue the installation of
The next step is laminating of glued strips with a roller( preferably steel, weighing not less than 10 kg) to distribute the glue evenly and remove air from under the coating. First you need to roll across the canvas, and then after 15 minutes - along.
Overlaps at joints cut the with an angle knife so that only the top edges are joined so that when the adhesive is expanded under the influence of the water component of the glue, there would be no extrusion of the linoleum in the seam area, which would happen if the edges were joined along the entire thickness of the coating. Now carefully roll the joints and finish the work until the glue dries completely.
After drying with , we extend the joints of under the welding cord, then carefully vacuum the seam. Before soldering the seams on the hairdryer, it is necessary to put on a special nozzle for the welding cord and heat to 350 ° C.
After sealing of all seams with a sickle-shaped knife( hot) cut most of the protruding seam. We finish the finishing of the joints after they cool down to avoid the formation of grooves in place of the joints, due to their shrinkage. Cover from natural linoleum is ready for operation.
