To the walls were smooth

Probably at home with initially smooth and straight walls never existed. One way or another, and each homeowner or had yet to align the wall, using a "heavy plaster case" and "Plasterboard craft». Each of these methods has its advantages and weaknesses, supporters and harsh criticism. On the experience of our portal users, we analyze the cases in which a better use of plasterboard in which plaster, and how to do it right, and talk about the tools that help determine the degree of curvature.

The measured curvature walls

First of all, it is necessary to determine the degree of irregularities of the walls. For beginners, the so-called "teapot", the easiest way to measure the roughness of a laser level that can "shoot for a day" from a friend.

Makinsk-KZ (Member FORUMHOUSE):

Laser level is set parallel to the wall, at the point of serving. Beam leveling draws the line the walls of the future. If you are going to install the FCL, the most protruding part of the (hill) walls should be at least 30mm to retreat, because Guide profile width of 28mm.

Pavlovich P34 (User FORUMHOUSE):

The laser beam will draw a strictly vertical plane. On top of "the belly" to set point, and the failures of the beam will show the maximum depth of the layer in the pits. Here and see everything clearly kettle.

The traditional method of measuring the curving walls - with a long level (2-2.5 m) - "pass" level vertically across the surface at intervals of about a meter, and to find the most protruding position. To measure the curvature of the walls should be horizontal thread, natnutoy two self-tapping screws screwed into the wall at the opposite ends of the room. The angle of the thread to be measured using the polygon.

Makinsk-KZ:

You can take a short level of 50-70cm and primotat him to rule, or a piece of duct tape profile.

How to measure the curvature of the wall construction plumb

Another method of determining the curvature of the walls: a construction using a plumb or nut, attached to a solid thread.

Under the ceiling in the corner of a room is driven a nail that needs to stick out from the wall about 3 cm. To nail attached plumb line on a string long enough to load quite a bit not reach the floor. Stopped rocking, the thread forms a straight line. In the lower part of the wall hammered another nail, so that his head and thread are aligned.

Such beacons nails driven into the walls around the perimeter, will give us complete information about the curvature of the walls. Pulling two strands, crosswise, on the upper right corner to the lower left, and vice versa, we will make that information is almost exhaustive.

What a way to align the walls choose

Plaster or cement composition for alignment of walls are traditionally used with little deviation, and after that the drywall, but the experience of the participants FORUMHOUSE shows that their ability It is much broader. On our portal the question "Plasterboard vs PLASTER" viewed from different angles. Each of these methods has both advantages and weaknesses.

Buryat (User FORUMHOUSE):

What is not like an ordinary plaster, one part cement + lime razbodyazhennaya ductility + 3 parts sand (suspended)?

In favor of the plaster following facts: this method does not eat a useful area of ​​a room, it is cheaper at the wall appropriate skills can make a smooth "like surface of the lake in calm weather," plaster - robust and sturdy material; always possible to repair only the portion of the wall.

Disadvantages of this method: the complexity and dirt, plaster dries long and inhibits further processes putty-color, moreover, without the presence of certain skills to the wall plaster is not even out, and the main thing:

Buryat:

Consumption of materials for the plaster is highly dependent on the curvature of the walls.

Therefore crude surfacing method using the gypsum plaster or cement is usually used as the walls are not especially curves, and it is required to correct defects is not catastrophic. Otherwise, there are two problems: too high consumption of material (respectively, and money) and a danger that the excessively thick plaster layer will not hold on vertical surfaces.

Buryat:

When deviations of 2-2,5 cm may be safely applied plaster.
When deviations of up to 4 cm - is thoughtful occasion.
When quite uneven walls, you can still make plaster - if the operation outweigh considerations.

The average thickness of the plaster layer is calculated depending on the design of irregularities.

Pavlovich P34:

The middle layer will determine, based on the minimum layer over the "paunch" of 3 mm, and further plyusuem 3 mm thickness to troughs.

Thus, if the depth of the largest dimples is 10 mm above the layer of plaster will be 13 mm.

Pavlovich P34:

Indicative layer is seen as 8 mm.

More precisely know the size of the middle layer can assess which surface areas greater, up to 6 mm (small) or greater than 6 mm (depth). If small, subtract and accept the middle layer as a 6-7 mm if deep, then we add, and the size of the middle layer is 9-10 mm.

Depending on the size of the middle layer, the need to forward the mixture, considering flow of dry mixture per 1 sq. m.

"A layer of plaster on the average" is different from the thickness of the layer that you apply in reality its thickness throughout the wall will vary.

Buryat:

If the surface of the bulge - plaster in some places is reduced to 3-4 mm. If, on the contrary - "vpuklosti" - the thickness of the gallop increases to 3.5 cm. So that the walls with deviations up to 2 cm can be safely cover the plaster and not worry about the increase of the layer thickness. Particularly healthy bulge can simply podtesat.

Dry walls alignment method is carried out mainly by a sheet of drywall, or which are mounted on a frame made of metal profiles, or simply glued to the surface. In the first case lost centimeters square house, so it is used mainly in large rooms.

Advantages plasterboard: it can be fastened directly to the adhesive mixture of the wall (if it is sufficiently smooth) This method does not require complex preparation, working with non-professional drywall is much easier than with plaster; there is no dirt. Another advantage of plasterboard: the ability to hide underneath communications.

Disadvantages: "eaten up" living area. The conventional wisdom that the plasterboard surface is not as strong and can not withstand the load hanging cabinets, etc., does not correspond to reality.

Makinsk-KZ:

The walls of the FCL can withstand even the water heater, even hanging toilet, and especially kitchen cabinets. Everything depends on the correct installation.

 And the most annoying member FORUMHOUSE disadvantage of this material, no matter how strange, unpleasant sound when tapped.

stanspb (User FORUMHOUSE):

No, but sometimes you have to lean on, knock. I do not like this buzz in my understanding of the wall should be a stone.

How to align the wall with plaster

Wet the alignment begins with preparatory work: the walls, if necessary, are stripped from the crumbling traces of the previous finish, cracks are eliminated. Necessarily primed surface and well dried. Before proceeding to the main work, it is necessary to protect the floor, carpeted it with something that does not spoil the solution.

After that, install the flashing profiles.

Pool (User FORUMHOUSE):

This strip from corner to corner (or floor to ceiling) at a distance from each other, which must be in the same plane. This plane will hereinafter plane plaster.

AMK (User FORUMHOUSE):

I install beacons used for thin-walled aluminum profile 25x50 mm 6 m long, cut into pieces of 5-10 cm and a width less than the height of the walls.

Now DIY stores sell special beacons for plaster.

Beacons are fixed at opposite ends of the wall solution, checking the level of their vertical position. Then pull cord therebetween at three locations at equal distances and, guided by him, establish other beacons. How many lighthouses should be depends on the size of the rules: it must fit between the two beacons so that rely on them.

For plastering premises often choose a mixture of plaster, bathroom, kitchen, etc. - Cement-based solutions. But now there are a mixture of plaster, suitable for important buildings, as well as plaster and cement based, used for surfacing in a residential area.

Regulus (User FORUMHOUSE):

I would use it a cement-sand plaster due to the thermo-physical properties of the resulting sandwich wall. coefficient of thermal conductivity is very high. Increases the thermal inertia of the walls and the dew point is approached as in the case of the hovercraft plasterboard.

For independent plasters for preparing such sand is mixed with cement (typically 6: 1 but other proportions may be 3: 1, etc.) and diluted with water to a consistency of sour cream.

The house, plaster cement-sand mortar, to live is uncomfortable enough, then preferably cement-lime plaster. Here is an example of the composition:

Buryat:

100 solution Cubes:

• Lump lime for construction, grade 1 - 14 tons.
• Slag cement for general construction and special-purpose grade 300 - 20.4 tons.
• Sand for construction works for plaster finishing coat very fine natural - 110 m3.
• Water - 66 m3.

Gypsum plaster into the water and pour into a two phase knead construction mixer or a drill with a nozzle: first, just until smooth, then repeating kneading in five minutes.

Falcon's apply plaster mixture between beacons and smoothes h-rule upwards evenly distributing plaster on the surface, orienting beacons layer thickness (subsequently pulled out of their apertures and fill the resulting solution). Leveling plaster help to make straight the corners. Leveled surface is dried and soils, after the primer has dried proceed to putty.

How to align the surface with drywall

The surface, which can be vyovnyat using drywall, can be very rough - Old brick wall. But if on the surface of the drops do not exceed 40 mm, then it can be a special glue glued sheets GCR.

Patrol84 (User FORUMHOUSE):

For half an hour pasted two sheets in a single plane. An hour later a monolith, absolutely no progress: trying at the outer corner of the bend, or at least something to do, all in vain. A feeling that the room was simply plastered!

If the wall is uneven, drywall sheets are attached to the frame profile.

First, to the floor and ceiling profiles screw guides (parallelism plumb verified), then the vertical guides mounted at a distance of 40-60 cm from each other.

Pict (User FORUMHOUSE):

Profiles of 60 cm - ideal distance for GCR 12.5 mm thick, if more than 60 cm, it is necessary to add a jumper from the profile, plus a jumper on all mating seams!

When abutting walls at guiding profiles pasted rubber band. And since the tape is not only the expansion joint, but also sound insulation, if necessary, glue it and a guide, and under suspension.

If necessary, between the wall of the house and is plasterboard liner insulation or soundproofing, and then closes plasterboard construction (two sheets back to back are mounted on a single profile). The sheets are fixed with screws so that their hats left in the sheet to a depth of about 1.5 mm.

Left align the putty seams and fixing the place and proceed to putty. Caulking and drywall need to wallpapering (otherwise they would shine), and prior to painting.

Qualitative coat layer 3 is obtained.

The first layer - the surface align a large spatula, the second -fill irregularities, the third - smoothing the surface of the liquid filler and a small spatula.
