Sealing of wooden houses: popular methods and materials

Due to the ability of wood to "breathe", a special microclimate is created in wooden houses. However, the flip side of the coin are cracks at the seams and cracks that occur during operation. How to return the walls leak and to minimize heat loss - will deal with craftsmen FORUMHOUSE. Consider:

• Why wooden walls in need of grouting.
• What is konopatka.
• What is a warm seam.

After dinner comes the reckoning, or why wooden houses require attention

Wood is not only the most environmentally friendly building material, but also the most deformable - it shrinks rassyhaetsya changes the geometry with the change of humidity. Particularly susceptible to these phenomena from chopped or log-logs and natural moisture lumber. During assembly of wooden boxes necessarily used mezhventsovogo insulation, stacked in a row, but in order to completely seal the seams, it is not enough.

As the thickness of the shrinkage joints between the logs / timbers increases, and through them, not only escapes from the house warm, but also inside the wall gets wet.

It is fraught with both extra cost of heating and reduction in the strength and durability of the structure. Therefore, after a certain time interval it depends both on the quality of the timber, and quality of assembly requires sealing joints and cracks. two ways of sealing the wooden walls are in demand - and warm konopatka seam.

konopatka

The traditional method of processing seams - by means of special devices grooves maximally tightly filled natural insulator to form the face of the small roller.

Caulk the wall and the outside and the inside, this method not only allows you to get rid of the cracks and to minimize heat loss, but also increases the decorative effect. Since ancient times used for caulking Moss, who also served as an antiseptic function, but today most often use other natural materials - lnovatin, felt, hemp or jute.

Primary konopatka carried out simultaneously with the assembly of the box - use a wide mezhventsovogo insulation from the rim forming roller and driven into the seam.

The following processing is carried out after shrinking and sanding log, the best option - two years (CBS) or one year, if the settlement is planned before. But in this case you may need to repeat after the first heating season. For many urgent concern of one of our craftsmen.

Long read threads on the forum, but did not come to a consensus. Now there is a grinding log, I thought then caulk and paint. Log houses 1 year. But many people write, it is better to caulk a year after the heating installation to rassohlis timber, and then caulk again. And heating costs during the winter? How to do it better?

How to find experienced forum users, is worth the wait.

Plotnik29 (FORUMHOUSE User):

The most optimal solution - a caulk after two heating seasons.

IPaltus (User FORUMHOUSE):

Now tuck frankly questionable locations, including heating and caulk on the second or even third year.

Of course, it is necessary to heat the street, but it is justified.

avsergeev71 (User FORUMHOUSE):

Believe me, for re konopatku costs (as it in this case necessarily have to do) are not comparable with the cost of heating season. And about a year - I would not wait a year, but two.

To heat losses are not critical, and blowing through the seams did not replace the ventilation, at the stage of the assembly is not necessary to save on mezhventsovogo warming. glyuck can not afford to wait just because a responsible approach.

glyuck:

Will do so, at the time I decided not to caulk today. Especially, I was placed on the thickest frame superdzhut, and even each log is a huge sledgehammer ramming. It is now quite tight all lies, but in any case within two years caulked, as you advised.

Houses assembled from a simple bar of natural moisture, also subject to shrinkage, though to a lesser extent than the log. The build process also applies mezhventsovogo insulation and konopatka held on average one and a half years.

warm seam

Warm seam is applied in homes or chopped logs, and in the homes of a conventional, profiled and laminated veneer lumber. Especially prevalent this technology is on the profiled bar of natural humidity as caulk difficult because the tool joint, and the need for grouting is. Properly assembled box of laminated veneer lumber provides minimal shrinkage, and in most cases more grout in the walls is not required. But if the need does arise, warm seam - the best option.

It is an advanced technology that involves the use of synthetic materials - polymer filler and acrylic sealant. Filler is a flexible cord made of polyethylene foam or thin ribbon, a cord is used for filling of thick seams and crevices tape - for narrow. the string / belt seam on top is filled with sealant, the layer thickness is from 5 mm.

The composition is characterized by high adhesion to the surface and elasticity, it completely seals the seam and adjusts seasonal deformation timber.

Not everyone understands why use the cord / tape.

Vladimir_Ilich (User FORUMHOUSE):

Prompt, Seals harness before sealing - a necessary technical process, or a personal choice?

Holtsshutts (User FORUMHOUSE):

Of course, a personal choice: either to do, as it should be, and hence cost, it is checked on the properties, performance and beautiful, or whatever you want, ranging from "himself will understand" and "I think these details are superfluous" to "neighbor did so yesterday, he says that forever and ever". We are satisfied with both versions: in the first case we see a satisfied customer, in the second case the same house sale immediately doubled, and after a couple of years back the client - the buyer.

With an old tow should be more careful.

Interhouse (User FORUMHOUSE):

Sealant should only stick to the top and bottom of the log / board, and then it will work in tension and compression. If he will stick to the tow, he along with the tow of joint with the times and take off. Therefore, we first tamp or old tow or cut off, and then laid cord of polyethylene foam (to which the sealant does not adhere) and then apply the sealant.

Some also believe that really do without the seal.

Pilotajnik (User FORUMHOUSE):

With regard to sealing tow: if the house is "defend", place it where there is a gap. Where no cracks between the logs, it can not be laid, but it is subject to total shrinkage at home. There are examples of homes in which sealing is performed by such principle 5-6 years ago, and there are no problems.

As organic materials used for caulking, acrylic sealant is permeable, it prevents ingress of moisture from outside into the joints, but does not clog them.

Warm seam is performed after grinding and processing of wood walls antiseptic compositions.

Depending on the manufacturer, sealants produced both tinted and neutral color for the subsequent specialized oils, waxes or lapis lazuli. Given that the quality of service sealant is designed for 10-15 years, protective and decorative coatings require update more often, you should choose a specialized formulations Robust sanding wood before application.

Interhouse:

"LPs" colors are remarkable in that they are 5-7 years later updated without polishing, 1 layer of the same paint / oil / impregnation. The paint does not recommend it due to the fact that the timber is covered with a film. And in a few years will have to grind, t. To. The paint is simply not absorbed, it is in the best case.

Technology applying the sealant depends on the release form, plus each manufacturer gives their recommendations, but that the seam has turned out not only leak-proof and durable, our craftsmen can give a few tips.

Sibman22 (User FORUMHOUSE):

After applying the sealant always use more metal spatula under the weld size. Smoothing trowel allows to keep the uniformity of the seam, in thickness and in width. Available surface roughness, moistened with water smoothed ordinary kitchen sponge. It is removed from the timber and jambs, strokes and bloopers (immediately washed in a bucket and use more). Using the sponge allows you to visually smooth transition sealant with wood and leaves no clearly allocated seam contour boundaries.

Suit and modified his own rubber spatulas.

Nata-K (User FORUMHOUSE):

These are the spatulas have been made by us, have helped in the work, was still very soft brush to 25 mm.

Vasya Pupkin(User FORUMHOUSE):

How I did lay out step by step.

• Extrude sealant must not regret, the sealant layer in the cord should not be less than 5 mm.
• Next, it is necessary to smooth the sealant with a spatula, if necessary, sprinkle water.
• Take the flat brush, we sprinkle some water on it and gently smoothed, sprinkles and smoothes, smoothes and sprinkles. The seam is better not to splash all flows. Then gently wipe with a cloth along the contour of the joint streaks also corrected uneven strokes.

With regard to timing, the miracles do not happen, if the box is made of glued beam, sealant is also used after complete shrinkage.

Vladimir_Ilich:

House of CBS, assembled 01.30.16, between logs jute, 15 mm thick, planned after a year of sludge sanded, caulked and painted, but now it turns out that the caulk is better after the first heating season. Instead of thinking about the sealant caulking, but it turns out, too, need to wait?

The main thing - to protect the timber and sealing the really have to wait.

Interhouse:

So far, color, grinding as needed. From the streets is required, one layer of priming antiseptic and two layer coatings. At the expense of sealing, all right, you need to wait. Otherwise, the load on the sealant will be large (at the time of log shrinkage shrink, and twists), that not every sealant stand, you can throw money away. Next summer, I think, you can schedule a seal.

And konopatka and warm seam quite popular among craftsmen portal, argue, what technology is better, it is meaningless, everyone chooses, based on their own preferences and capabilities. But underestimated the need for caulking is not necessary, it is one of the essential operations when it comes to the exploitation of wooden houses.
