It is difficult to imagine construction and repair work, which would not apply the drywall. It is made of internal partitions, boxes for water and sewer pipes, multilevel ceilings, arches, decorative elements in the interior. The drywall sheets line the walls, significant defects in slabs.
Smooth, broken, rounded drywall construction before painting or wallpapering should be fine. How to putty drywall, not being a master of finishing, we’ll cover in this article.
Tools ↑
For independent work you will need:
- foam rollers and brushes for priming,
- spatulas stainless steel with a width of 10, 20 and 40-50 cm,
- capacity for the mixture and for water,
- grinding grater with mounts for mesh or paper,
- sandpaper or sanding paint the grid,
- mixer attachment on a drill,
- construction knife
- a rule with a length of 1.5-2.0 m
- respirator, goggles, rubber gloves.
The materials ↑
- a primer of deep penetration,
- putty,
- the junctions or perforated paper tape for joints,
- perforated angles, metal and plastic,
- fiberglass,
- adhesive for fiberglass.
Putty ↑
Each novice finisher is better to putty drywall. To work apply rough and finish plaster plaster, cement or polymer. There are dry mixes and ready-made solutions.
For decoration with high humidity suitable cement, lime compounds or polymer putty.
For basic equipment use in gypsum plaster or cement fugenfuller of Hercules, for the top layer — finish polymeric Bergauf or Tserezit.
Surface preparation ↑
The quality of the finish depends on how well the drywall is ready for applying a layer of putty. To do this:
- with a knife to remove all loose paper coating;
- to extend the joints, cut on each side for 5 mm at an angle of 45on (to get a V-shaped junction), this will increase the contact area and the strength of the finish;
- the protruding heads of the screws to tighten flush with the surface of drywall or with a small depth (not more than 1 mm);
Priming ↑
The purpose of applying primer is to create a polymer film that prevents the penetration of moisture into and eventual delamination of the paper covering of drywall, as well as to increase the adhesion of the putty to the base.
A primer of deep penetration, you can use any, but the professionals recommend primer Cerezyme ST17. It creates a solid film. It is recommended to apply 2-3 coats, each applied after complete drying of the previous.
Preparation of the solution
Gypsum plaster is very demanding on the cleanliness of the container in which you can prepare a mixture, and quickly grasped. To prepare the solution should be 0.5–1 hour of work according to the instructions on the package.
Falling asleep dry powder in water, add it until then, until the surface appears dry Islands. This suggests that the proportions observed. The mixture should quickly stir until homogeneous and no lumps and leave for 5 minutes. Caulking should be thick sour cream. Then stir again and you are ready to work.
Prepare corners and joints ↑
A skim coat of drywall begins with the preparation of corners and joints. Here you will need a narrow spatula and a small amount of the solution.
What is putty putty the seams of the drywall? For this purpose, the composition of Knauf Fugen. Embroidered with the joints filled with the mixture, then stick the self-adhesive strip special mesh or perforated paper and smooth down with a spatula. The mesh width of 5-10 cm will provide a solid grip.
- External angles are reinforced with metal corners, securing them with a solution of putty, as follows: put a bump on both sides of the solution and pressed against the area. Excess solution is smooth down with a spatula, removing excess.
- Curved corners on drywall fix plastic corners with steppleton and solution in the same way.
- Internal corners are sealed with reinforcing mesh on each side so that the ends of the grid was in contact in the corner to prevent bending, and sealed solution, trying to exactly fill the joint. Sometimes the ceiling between the wall and the edge of the drywall sheet may be a large distance (1-2 cm). These close up angles differently: put a layer of plaster, trying to pin her to the end of the sheet of drywall for better adhesion and carefully aligning the angle. After drying, primed, glued serpyanku and putty.
- Place screwing screws in drywall also sealed solution.
After drying putty, we should check whether the stuck filament reinforcing mesh, remove them with a knife, irregularities in the sealing cut carefully with a spatula and all primed.
The puttying ↑
Putty drywall on the ceiling and walls is different depending on the final finish. If you plan to apply Wallpaper, it will be enough primary and finishing layer of putty. To finish painting and Venetian plaster will need fiberglass.
How to spackle a ceiling ↑
The ceiling can be the finishing putty from putty in 1-2 layers. Work from any wall in good light.
This is done as follows:
On a wide spatula, put a small amount of the solution and the broad movements of the wall itself or from itself it is applied to the surface. Once processed enough space, the layer is permanently wetted with water level rule. The wizard does not use the rule, but the novice finisher it will prove useful. So treat the entire surface.
If the layer of the dried up putty is not discernible dark spots of drywall, this can be limited. If the layer is uneven, it is necessary to apply a second. This roughness is removed by grinding mesh, the ceiling is primed and shpaklyuyut again. Dried up the surface carefully sanded, remove the dust and it is applied to soil for painting.
How to putty drywall under the Wallpaper ↑
To be clear, how to spackle drywall, video from experienced craftsmen will help you to understand all the details.
You’ll need wide and narrow spatulas. To coat was high quality, please note a few subtleties:
- the spatula should not have curved corners, chipping and other defects on the working surface;
- in the process you need to follow to lumps of dried mortar and other debris were not included in the solution and on the spatula. They will leave on the surface of the strip, are difficult to handle;
- the remains of the mortar should be removed from both sides of the working surface of the spatula. The dried solution is better to throw in the trash.
Work order:
- put narrow spatula evenly a small amount of mixture on the edge of the working surface wide spatula,
- starting at a corner, wave-like motions, apply it on the wall and carefully smoothed with a spatula movements in different directions. You can do a semicircular motion, wavy, but not straight. Start drawing better with a clean section, moving to the processed part;
- the remaining solution collect narrow spatula again, and spread evenly over a wide surface, adding a fresh portion;
- remove the defects of the dried layer of sanding mesh or abrasive paper;
- clean the surface from dust big brush or a cloth;
- apply the primer;
- to the primed surface in the same way apply a layer of finishing putty, finish after drying, paint grinding mesh number 180-220 a circular motion;
- clean the surface from dust and primed.
How to putty drywall before painting and decorative plaster ↑
When finishing drywall walls and ceilings in new brick houses, but also for painting or decorative Venetian plaster, should reinforce the surface of a thin glass fiber.
It will prevent the appearance of cracks and other defects. The sheet of fiberglass glued to sanded and primed with a layer of putty with PVA glue, or fiberglass is as follows:
- the adhesive is applied on the wall evenly,
- impose lapped (3-5 cm) of a cloth of glass fiber, trying to keep their joints do not fall at the joints of drywall,
- the canvas is carefully leveled and hand trowel, removing him out of the air,
- after hanging the two paintings of the place of overlap are cut using a knife construction, a surplus of canvas removed, the joints align,
- the canvas top is again covered with glue and smooth down with a spatula.
On cured adhesive applied in a thin layer of finishing putty, and sanded carefully align the masking grid. After sanding and dust removal, the surface is covered with primer deep penetration for 1-2 times.
The thus-prepared plasterboard walls are flat, smooth, ready to cover any finishing materials.
