Special quality mixtures, eg, fire resistance or frost, in this case does not play any role, is more important to pay attention to the appointment of putty and then, in what room it will be ispolzovatsya.Tak, gypsum plaster is more suitable for dry rooms, because it is afraid of the big changes in humidity and can crack. Therefore, for a bathroom or kitchen is better to use putty, cement-base.
Leveling compound is good for joints, cracks and dents. It has a coarse texture, Consequently, like finish suitable only, if the wallpaper has a greater material thickness and density.
Universal polymer filler can be used for planarizing, and for the final finish. It is suitable for facilities with any moisture. And its consumption is less than that of other types of fillers.
Choosing a putty putty drywall under the wallpaper is better to give preference to the dry mixture, because it lasts longer and can be used in doses, kneading much, how much do you need.

surface preparation
Before starting putty plasterboard, it must be cleaned of dirt and dust, and carefully inspect for scratches, deep dents and protruding screws. This can help a regular spatula. Leading them on a plane plaster is easy to detect various defects.
Underturned screws should pull your screwdriver, slightly sinking their heads into the top layer of plasterboard. If there are screws, hats which were included in the body of the GCR too deep (more than half of the sheet thickness), they must be removed and spin in a new location, at least 50 mm from the old point of attachment. A smaller distance is not recommended, since the holes can be formed crack, which is likely to spread further, and therefore, This list will need to be replaced.
If gypsum boards at the joints do not have a factory chamfer, their edges are cut at an angle necessary to 45 degrees. This is necessary in order, to putty deeply penetrated deep into the seam. Besides, at the edges of the sheets should not be peeling paper from gypsum. Upon detection of such a defect, who quit need cardboard neatly trimmed with a knife, a place primed. In details, how and what to gloss over the drywall joints.
After a visual inspection and detection of all flaws plasterboard wall must be primed. As a primer is better to use a mixture of a water-based, since they are impregnated cardboard layer only and do not cause its deformation. The primer should be applied uniformly over the entire surface of the plasterboard, thin layer. When it is completely dry, you are ready to advance Shpatlevanie.
Pre Shpatlevanie
Preliminary plaster drywall under the wallpaper with your own hands is aimed at leveling the surface and includes:
- sealing of seams and joints;
- Shpatlevanie screws;
- Shpatlevanie angles;
- alignment of dents and other defects.
Putty seams and joints between the sheets of plaster to walls, ceiling and floor should begin with the reinforcement tape stickers - serpyanku. It is important to stick it so, to close up the slot was in the middle of the tape. Now it is possible to apply filler. The work is conducted from top to bottom, it is convenient to use two spatula - narrow and wide. The first seam can be filled with a mixture of, a second align it over the surface of the longitudinal movements. Putty does not need to be sorry, since when drying it gives a significant shrinkage. The result should be completely filled with a seam, without gaps and visible indentations. It is better if there is a slight excess putty - then it is possible to remove abrasive mesh.
Putty is applied on the screws crosswise. So it fills the recesses of the fixing caps and hides its head.
When a plaster walls of drywall under the wallpaper, perhaps, the most complex operation - it Shpatlevanie angles. often used perforated area of aluminum for the outer corner or, if the angle of the curved or arched, plasty. Get this profile is quite simple. To do this, you need to make to the corner of the place, in which it is mounted. Make a pencil mark, and then make an incision along the lines of plasterboard, spaced about 3 mm pometok, when viewed from ugla.Posle it with a chisel to remove the cardboard to a depth slightly greater, than the thickness of the corner. The resulting recesses are filled with putty, and then pressed into a corner profile in them so, to be slightly deeper relative to the plane through the perforations putty sten.Vystupivshaya smoothed wide spatula with addition of a mixture, to get aligned with the plane of the sheet surface. Video of the puttying of walls and ceilings.
Inside corners shpaklyuyut little harder. First of all, They as well as the seams are reinforced serpyanku. Secondly, to evenly bring the two adjacent sides, they shpatljujut turns - first one side, then, after complete drying of the first, second. It facilitates the work of a special trowel for corners, which can be easily found.
dents, deep scratches and other imperfections are sealed standard method. In this case, if the filler will need to be applied in several layers, each subsequent layer is applied only, when dry previous. To evaluate, how exactly it puttied wall,You can use the usual spirit level.
After finishing preliminary Shpatlevanie walls of plasterboard, must overwrite their sand mesh, cleaned and re-coat primer.
Final putty plasterboard
