Processing the floor log from decay and moisture is mandatory, even if the wood is of high quality and was originally varnished and the room is not too humid. In fact, lags in any case are prone to rotting for a number of reasons:

• an unpleasant musty smell is heard, and it makes itself felt even after general cleaning.

If nothing is done, the entire structure can collapse in 3 or even 2 years. In addition, when wood rots, toxic substances enter the air, and their concentration increases in summer due to rising temperatures. In advanced cases, the lags will simply break, the floor will partially collapse - there is a risk of injury.

Now it's time to learn about how to process sexual lags. Normally, building material receives industrial impregnation at the factory. Special formulations are used to protect against decay, insects and rodents. But even if it has not been done, you can carry out the treatment at home using antiseptics or folk remedies.

1. Impregnation is done after laying the log - otherwise it is easy to break the protective layer during installation.
2. The work is carried out at a positive temperature, preferably above +10°C.
3. For processing, you can use a brush (easily penetrates into hard-to-reach places) or a roller (for greater coverage). You can also use a sprayer - in this case, labor productivity increases.
4. Processing the lag by mining involves the use of special chemical compounds, so the room is ventilated both before and after.
5. The basic rule is that the antiseptic for the log floor must be applied evenly, allowing the composition to dry, which takes only an hour.
