The seal cracks in the wooden house?

DTo seal gaps and cracks in the wood (beams or the logs) there are three main means of them will talk about later, but for the beginning of the answer to the question:

Why there are cracks in the wooden house?
Wood - a porous building material, constantly absorbing the moisture and donor. The thicker the wood moisture is distributed unevenly: first it impregnates its upper layer, after - penetrates.

BThe higher wood moisture, water more deeply penetrated into the timber body. When the humidity in the room or on the street wood moisture falls below it starts to give a moisture outside, this process is called shrinkage.

When shrinkage of wood loses moisture, dry pores shrink, and a bar or a log decrease in size. Because of this, something between the logs and there are gaps, which are in villages regularly caulk.

EIf during the construction of wooden houses has been used timber or timber of natural moisture, ie unseasoned or not fully dried, the shrinkage of causing serious harm to the material: the outer layers of wood dry and reduced in size, while the interior remained filled water. As a result, a crack formed in the outer layers.

Important:
You will never see the cracks in the houses of laminated veneer lumber, because before construction lumber drying chamber passes, which uniformly removes all moisture from the timber body.

Why is everyone afraid of cracks in the wooden house? Perhaps the most convincing answer I found in the book "House. Practical recommendations for the construction and purchase their own homes " where such a scheme is represented:

The seal the joints in the wooden house?
To repair cracks in wooden houses using three methods:

• konopatka;
• Shpatlevanie;

• sealing;

IN the first case (konopatka) Using the same name and the hammer tool is made lnovatinom sealing gaps, a rope or rot-moss (see photo).

For more information about caulking - here.

The main drawback of caulking the outer portion of non-insulated log home is that the birds are pulled jute and linen for the construction and insulation of the nest.

PWhen the second method (Shpatlevanie) It is important to know the following: if the crack in the timber is less than 3 mm, then for its termination can apply solid wood putty. If the gap larger than 3 mm, it is better to seal the mixture of PVAc and sawdust.

ABOUTIt explained with this fact is that over the years the wood is not time to change their size, and the solid filler simply crumble out of the slot during a set of wood moisture, or fails in the slot during further shrinkage.

Trety method - pressurization - for it is generally used specialized sealants based on acrylic. Ranked Among its indisputable advantages - good price (150 rubles per 300 ml) and reliability (serves 12-15).

important thing
# 1 After applying the sealant remains of it must be cut, and the ends of the handle antiseptic.

important thing
# 2If a crack in the beam is very wide, in its rear part must be caulked with flax or jute, and only then begin to fill its cavity acrylic sealant.
