How to grind log of logs - the procedure works and tools

Many private developers the question arises why it should be done, if each workpiece has passed the appropriate treatment of industrial process?The more that a variety of advertising, attracting potential customers and promising them construction of the house of any architecture "turnkey" rarely indicate the need for additional surface treatment.It would seem, he has built - and forgotten.However, this is not quite true.

Why resurfacing

1. During shrinkage, under the influence of temperature, humidity thinnest surface layer (bast) begins to separate (flake).The surface of the walls is covered with unobtrusive loose crust, which eventually becomes visible.How this affects the appearance of the building, there is no point in talking.

1. To ensure good adhesion of the processed surfaces.After all round logs - it is wood, and the building material requires quality protection from external influences (UV, moisture).Even if painting is not made (in some cases this is done), the surface treatment Coating - a mandatory step exterior trim.

Even on the quality of logs will always be present invisible microscopic fibers (lint).If they are not removed, then subsequently applied paint composition will gradually peel off, peel off.So much cheaper and better to do grinding log directly than when operating systematically restoration work.

1. sanding lacquer achieved significant savings without compromising the quality of work, reducing the time required for their implementation.

1. presence of tiny fibers on the material promotes the growth of fungi and other microorganisms, and a variety of insects, many of which destroy the wood.

1. We should not exclude the appearance of defects on the workpiece surfaces due to the malfunction of woodworking equipment, after transportation to the construction site.Grinding eliminates quickly such "point" of damage.

1. Do not forget the aesthetic side of the issue.After each log is individually structured pattern.Ground surface more clearly emphasizes its prominence, gives any structure only their own, unique character.

Tool - "The Bulgarian»

necessary to use a model in which the speed control is provided.Each type of wood has a density (hardness), so the grinding wheel rotation speed is chosen empirically.On the one hand - wood should not "smoke" on the other - it is necessary to achieve the required quality of processing.

Main stages

1. Pre-impregnation of flame retardants and antiseptics (if logs, timber already purchased dusky shade with blue signs).

1. Grinding.

• surface treatment disc 80 with the grain, then - with a density of 120;
• vibration work, sander - removal of any scratches, giving absolute "smoothness" of the wood.

In the process of grinding necessary to control the uniformity of the pressure on the tool.Otherwise, there will be specific "spot", "divorce".

1. Secondary Coating surfaces spetssostavami (same against biological pests and fire, read more here).To better their penetration deep into the structure of this work is carried out at least 2 times.

Features of work

• material must dry.If we accept the processing of raw blanks, the significantly complicated and delayed the whole process, as an instrument (its abrasive parts) will always have to be cleaned or replaced.
• Grinding is carried out only during the warmer months.
• walls are processed, not only outside, but also inside the building.
• face of the work is not an abrasive, and a plastic nozzle to the "grinder".
• Where the machine can not be applied, work is being done with the help of ostrozatochennoy chisels, sandpaper.
• To begin the work necessary only after the completion of the construction works, that is, when the roof is already installed.And it is not earlier than 1 - 1.5 months.
• To begin to try or on the remains of the material, or in a place where traces (in the case of "marriage" in the work) will be invisible.
• Be sure to use protective equipment.Microscopic dust penetrates quickly into the airways clogged with eyes.So do not get to work without special glasses and respirator.
• Covering ground surfaces paint compositions should be made no later than 3 days after their treatment.

appropriate to bring the average cost of certain types of work.But we must understand that a lot depends on the complexity of the architecture, altitude, and other factors.
