Sanding timber is one of the most important processes in the construction of a wooden cottage. It allows you to remove the bark from the bars, make them perfectly even and attractive, and also eliminate various defects. In addition, grinding can significantly increase the performance of this material and make it more durable.

Today, many companies provide professional wood sanding services, but their cost is very high, so many people are thinking about how to sand wood well at home. If you follow the basic tips and recommendations that will be given below, then grinding a house from a bar with your own hands will turn out no worse than when ordering similar services from construction companies.

Why do you need to grind the beam?

The surface of a wooden beam has a roughness, which is a common occurrence and appears as a result of sawing wood on a machine. If you do this work manually, hairiness can be avoided, but there will be much more other defects on the tree, which will significantly reduce the quality and durability of the timber.

WhenFor exterior decoration, hairiness can be hidden by cladding, but inside the room it will spoil all the aesthetics and attractiveness of the interior. In addition, ideal conditions for the appearance of fungus, mold and various microorganisms will be created in places of chips and cracks.

Grinding the timber inside the house helps not only to avoid all this, but also to achieve the following:

• make the walls inside the house perfectly smooth;
• fix various defects;
• get rid of fungal spores before impregnating wood with antiseptics;
• improve the quality of adhesion of timber with paintwork materials;
• give wood a more attractive look and texture.

Despite all of the above benefits that indoor sanding provides, many experienced builders recommend waiting a bit for the building to settle before doing it. This is quite understandable, however, if the defects that are on the timber are not immediately eliminated, then they can become much larger, as a result of which it will be impossible to achieve an aesthetic appearance in the future.

The only way out of this situation will be to remove a rather thick layer from the beam, which not only requires large physical and time costs, but also negatively affects the performance of the tree. Therefore, the grinding of the timber should be performed immediately after the completion of the construction of a country house.

What tools will be required in the grinding processwalls?

In order for grinding to be done as quickly and efficiently as possible, you will need to acquire the following tools:

• grinding machine;
• belt sander;
• grinder with nozzles for woodworking;
• chisel and sandpaper.

The grinder is a professional tool designed to work with profiled timber. It allows you to perform all the work very high quality, but its purchase will cost approximately 150 thousand rubles. Such an amount may not be affordable for everyone, so renting it will be the best solution. A belt sander is designed to work with glued laminated timber, the average cost of which is approximately two thousand rubles.

If your budget does not allow you to purchase specialized equipment, then sanding walls from a bar can be done using an electric drill and a grinding nozzle, which is included in the factory equipment of almost all angle grinders.

Sanding is done in stages using nozzles with different hardness levels. First of all, the timber is sanded with the No. 80 nozzle, which is intended for primary processing, after which the No. 120 nozzle is used, which will give the tree a perfect appearance.

General tips and tricks for sanding wood beams

In order for the beam to meet all your expectations after grinding, you must adhere to the following tips andrecommendations:

1. Sanding of timber walls should begin after the roof has been erected. This is very important, because during the construction of the roof, various defects may appear on the walls, which will have to be re-repaired.
2. It is strictly forbidden to grind an undried timber, as it will only spoil the nozzles, and the result of the work done is unlikely to satisfy you. An exception may be a tree cut down in winter.
3. If after the completion of construction work the wood has acquired a blue tint, then you should first bleach it with abrasive materials, and only then you can start sanding.
4. After the polishing of the beam is completed, it is necessary to treat the walls with a special antiseptic. If this is not done, the wood will darken.

Following these recommendations, you will be able to sand the walls of your cottage, and they will take on a completely different look, which will give the interior a very original, natural and attractive appearance.

Wooden beam wall sanding process

Now you have a detailed understanding of all the nuances associated with the grinding of timber, so you can start the process of doing the work. In order for the end result to be of high quality, grinding should be carried out strictly in a certain sequence, which will be presented below.

Step one: end face grinding

The end of the house is exposed to negative environmental factorslarger than the rest of its parts, so the grinding process should begin with it. If this stage is omitted, then the tree, having absorbed moisture, will swell very much and begin to crack. To prevent this from happening, the ends must first be sanded with a nozzle with high rigidity, then treated with a nozzle designed for finishing work, and polished at the very end. When the sanding of the ends is completed, the wood must be treated with special antiseptics.

Processing glued beams

Sanding of glued laminated timber should be carried out immediately after completion of construction work. This is due to the fact that this material has a low resistance to external stimuli. If the glued laminated timber dries, then fibers will stick out of it, which will not allow the wood to be sanded to a perfectly even state.

Processing profiled timber

If the country house was built from coniferous trees, then profiled timber can be sanded using nozzles of any hardness. However, there is one important nuance. If you have purchased material that has been treated with antiseptic agents, then after sanding is completed, the impregnation of the wood will need to be repeated.

Sanding process step by step guide

If, after the construction of the cottage on the beam, the bark remains, then it must be removed without fail. To do this, you can use a chisel or grinder with a special abrasive nozzle.

When the beam is ready for sanding, the wood is first processed with a nozzle withhigh rigidity, which will eliminate the pigment that leads to blackening of the wood. Then finishing grinding is performed, after which the beam will become perfectly smooth. If any defects are found on the material, then the tree should be treated with a special vibration nozzle.

At the final stage, the timber is treated with an antiseptic that will protect it from rot, fungus, mold and other pests. It is worth noting that the impregnation with an antiseptic must be done within a week after sanding, otherwise the wood will change its natural color, because of which everything will have to be repeated from the beginning.

As it turned out, it's not so hard to grind a beam. In the process of work, the main thing is to follow certain instructions and observe safety precautions.
