How to align the floor in the house with plywood on the joists with their hands - guide with photos and video

floor before finishing Alignment is performed using a variety of materials.Laying plywood on the load-bearing structure of the lag - one of the simplest methods.Perform all manufacturing operations without assistants and consultants, with their own hands, capable of even a beginner.About all the features of the floor assembly of plywood and will be discussed in this article.

choice of materials

Plywood

For everything it is advisable to purchase sheets of flooring (including cost) labeled FC (up to 3 years of guaranteed operation) or PSF (increased water resistance - up to 5).In the manufacture of veneer different species of wood used.Best for plywood birch considered.When

veneer bonding adhesives are used, which differ in their chemical composition, and hence the degree of toxicity (depending on the product).Therefore, FC sheets are recommended mainly for laying in premises, and PSF (as less "clean") - in all other (although preferably just outside the building, for example, for the arrangement of a solid roof battens).

Since the cost of the material is determined by, in particular, and its thickness should dwell on this matter.The strength of the design depends on this parameter, rough coat, the interval between the beams and the number of layers.Therefore, it can be combined.And yet, in any case should not be used for leveling floors thinner sheets of plywood 10 mm.

Useful tips

• To reduce the cost of the floor arrangement, should be limited to plywood 3 or 4 grades.It costs much cheaper, and the appearance of the sheets in this case is not important, as they will be covered with finishing material.
• This will help advance charting facilities.As it is easy to determine which size is better to buy sheets.The most common (m) - 1.5 x 1.5 and 2.4 x 1.2.The less need to cut, the more the material will go to the cause, for its intended purpose.Therefore, to reduce the amount of waste.Perhaps, given the complexity of the geometry of the room, it is advisable to buy plywood with different linear parameters.

Laghi

there are only 2 options - wood or metal sheets.With the latter is easier to work, and in terms of durability, they preferred the wooden blanks.Arguments significant, but they do not consider one nuance - temperature deformation of materials.For them, this ratio should be approximately the same.From this point of view, to avoid warpage floor, formation of cracks, it is advisable to stack veneer (taking into consideration its structure) is on wooden joists.

It is also important from a timber blank.Since the logs will not be in the best of circumstances (defined moisture under the floor can not be avoided), it should be guided only by pine trees, and above all - a larch.Of all the species, the most resistant to moisture, it is the cheapest.It is worth mentioning that it is not in vain in the old days it used it to lay the bottom row (the crown) framework.

fasteners

Of course, we can talk only about the galvanized hardware.But with what parameters?There is a general rule.fastener length should exceed the thickness of the sample fixed by 2.5 - 3 times.

Operation

Even if plywood is laid on the existing logs, instead of the removed floorboards, it is desirable to get acquainted with the full range of activities.Possibly taking into account this information, there is something thought to alter, improve.

Concrete Waterproofing

Activities such as cleaning base its examination, removal of defects such as cracks and crevices author deliberately skips - is the basics of repair.

Whatever may be the water-resistant plywood, but it is characterized by a certain hygroscopic.Therefore, gradual absorption of moisture can not be avoided.Previously the protective layer does not develop, it is a must-do.What to use - is achieved, depending on the specifics of the premises and the owner of financial opportunities.Perhaps the cheapest floor waterproofing option - p / e film (thick).

She covered the entire concrete floor, with small turn-up on the wall with the expectation that the material has performed several of plywood laid later (depending on the thickness).These edges then still closed plinths.The joints are sealed with tape webs (construction).

Previously the protective layer has not been installed, you have to think that it is easier and economically feasible - to dismantle the logs and all done "from scratch", or buy special impregnation (waterproofing penetrating).

lag Laying

distance between the rails is chosen to meet the requirements to the floor strength, size sheets and their thickness dimensions of insulation material and other installation features.But first and foremost it is necessary to focus on the plywood.Her mount is made with the fastener equidistance from the edge of about 10 mm (not to destroy the edge).fragments seam should be located on the longitudinal axis of the log (if possible).

Therefore, a single recommendation to give meaningless.That's why author and recommended to start an accurate diagram of the room.

Procedure lag mounting each skilled master his.But a number of features should specify:

• It is advisable not to fix the lag on the concrete, and exposed to a pre-support (according to the diagram).First, the gap provides better airflow under the floor.Second, the adjustment lag in height considerably simplified.
• work should begin on the walls.Indent - about 25 - 30 mm.After the alignment of horizontal extreme lag securely fixed, and it leveled all the other intermediate.

For orientation log level is used with respect to the horizontal plane (the building), but his body has a short length.So, not to avoid large errors.To minimize their expedient to fix the device on the rail.As a rule, it is sufficient that it be 1.5 - 2 meters (with more overall work is extremely inconvenient).

plywood mount

• Laid first row (of the window), checked the fit of all fragments and outline drilling point (lag of sheets from the walls - 2 mm).
• They are removed and processed for one - drill holes for fasteners made countersink (synonym - rassverlovka).It is necessary to completely drown hats.

Note! Do not get too "zealous" in an attempt to drive the screw deeper into the plywood with a screwdriver or a screwdriver.This will lead to cracks in the head region.

• edges of the sheets are processed (at an angle).After connecting the fragments formed groove, which is filled with sealant.Pros - partial improvement of the quality insulation, soundproofing and waterproofing the sub-floor.If necessary, cut out holes for the construction of communications lines.
• Final setting sheets in place and fixing them.Depending on the fragment size - perimeter (optional) and crosswise (or just in the center).

To reduce the risk of loosening of plywood on the joists (above) it is advisable to put a strip of roofing material.

sex Processing

Lies in the grinding of joints and sealing of all grooves and holes (over-head fasteners) sealant.

After that you can start finishing.
