Repairing a modern apartment is rarely complete without drywall. Alignment of walls, installation of partitions or the formation of design refinements in the form of arches, curved niches, columns cannot do without this universal material. Drywall is inferior to classical stucco in only one way: it does not "hold the punch" enough. A dent or hole may form under accidental circumstances or when it is planned, for example, to transfer outlets or hanging shelves to another location.
Therefore, an inexperienced master may have a question, how to seal a hole in a drywall on the wall? After all, the classical way of sealing holes in the plaster will not work here - behind the sheet there is usually a void or soft soundproofing material.
But do not worry that to eliminate the defect you will have to dismantle the damaged sheet as a whole, and buy a new one in its place. The technology for plugging holes in drywall is so simple that even a novice can handle it. Consider methods for repairing damage in order of increasing size.
How to close up holes up to 0.5 cm in drywall on the wall
Sealing holes in drywall left over from anchors, dowels, screws when moving furniture or shelves will not be difficult. To do this, you need acrylic sealant. It is squeezed into a recess and compared with a spatula to the wall plane. After drying, it will still have to be sanded with a mesh or sandpaper. And in the case of shrinkage of the glue and a small cavity in place of the hole, for the final disappearance of the defect, it is enough to apply the usual putty.
Through holes up to 3 cm
For repair you will need a minimum set of tools and materials:
- Sharp knife
- Sealant or PVA glue,
- Any material at hand to fill the hole. It can be crumpled paper or a piece of polystyrene left over from the packaging of purchased household appliances,
- Putty knife.
Before closing a hole in a drywall of this size, it is necessary to prepare the surface:
- They clean the edges so as to get a smooth inner surface without crumbling pieces and rags of paper,
- Carefully pass with primer the inner edge of the cleaned hole and the area around at a distance of 5 - 10 cm,
- The prepared lump of paper or foam is lubricated at the edges with glue and cover the hole with it. It is necessary to ensure that the edges of the makeshift “cork” do not protrude above the wall plane,
- After the glue dries, the sealed hole is putty.
Further actions depend on the type of decorative wall covering: painting requires careful alignment, as the slightest flaw is noticeable on the painted surface. Therefore, you may need another layer of putty and thoroughly smoothing fine-grained sandpaper.
Damage 3-6 cm
Repair of holes in drywall with a size of 3 to 6 cm or more is done using patches made from the same material. That's why you should not throw away trimmings from drywall after repair - several pieces should be left just in case. Otherwise, you will have to ask friends of the builders who work with the GKL.
The easiest way is to cut a round hole in the damaged area using a drill with a drywall nozzle (crown). The hole is obtained with smooth edges.
Next, they begin to make the patch with all that “crown”:
- Cut a square with sides 4 to 5 cm larger than the diameter,
- From the wrong side, a circle is drilled, not reaching the front paper layer,
- With a knife, a chisel or any improvised tool, clean the plaster. The result should be a round liner with a square front of paper,
- The patch and surface of the drywall are primed, not excluding the inside of the hole and the ribs of the liner,
- After the primer dries, a gypsum putty is applied to the edges of the hole and a patch is placed in the hole,
- The excess putty is distributed on the surface with a spatula, press the square part of the patch to the wall.
Further actions are puttying and finishing with decorative material using conventional technology.
Note: if there is no drill and special nozzles, the patch can be made square. To do this, you have to arm yourself with a pencil and a ruler so that the fragments match as accurately as possible.
Repair of large holes in drywall
Simple gluing of a patch is not suitable for large holes - there is a high probability of a glued fragment falling out. Therefore, before closing a hole in a drywall on a wall with a size of 10 cm or more, you will have to stock up on tools and materials:
- Screwdriver and / or drill,
- Wooden block or shtaket,
- A piece of drywall of the appropriate size,
- Primer, putty, putty knife.
First, a quadrangular fragment from GCR is cut out, slightly larger than the hole. By applying the patch to the damaged surface, mark the edges of the future hole. Then, drywall is carefully cut along the outlined lines. In order to prevent the seam from cracking in the future, the edges of the liner and holes are cleaned with a knife at an angle of 45 ° so that a groove of triangular section forms.
Next comes the turn of the frame for the patch: a wooden block (shtaket) is cut 5-6 cm longer than the hole and is pushed inside. Pressing it to the wrong side of the drywall, fasten the wooden frame with screws on the front side. The number of bars depends on the size of the hole - they should be enough for the fixed position of the liner.
Tip: For the convenience of working in the center or on the sides of the bar, you can screw the screws and wind the wire on them. Such an impromptu pen is then easily dismantled with a screwdriver.
After fixing the patch, the surface is primed. The joint seam is sealed with a serpentine and filled with base putty. After drying, impose a finishing putty and grind.
Repair of holes in drywall on the ceiling
The technology of the carcass device for large holes in drywall is the same for both vertical and horizontal surfaces. Therefore, the question of how to seal a hole in a drywall on the ceiling, beginners will not arise.
If you don’t have a drill and a screwdriver at hand, but there was a cylinder of construction foam left from the repair, then you can use it to fill a hole in the ceiling and form a stable base. Before filling the hole with foam, it is necessary to clean the inner edges of dust - this will ensure the adhesion of the foam to the inside of the drywall. After solidification, the foam is cut flush with the plane, putty. The method works on fragments up to 15 cm or with a small distance to the draft ceiling.
When closing ceiling defects formed by GCR soaking, it is worth remembering that before starting work, the ceiling should be thoroughly dried. Otherwise, mold will start under the drywall, which destructively affects health.
The listed methods are not the only ones possible. After all, drywall is a universal material that can work in an alliance with a variety of mixtures and solutions. How to seal a hole in a drywall? - ingenuity and imagination will tell the home master their ideas that will work no worse.
To close a hole in drywall is not necessary to have professional skills. Before starting any business, especially if it concerns repair, you need to carefully prepare for the process. Good preparation is already half the success.
As a rule, a hole that unexpectedly formed in a wall requires some cutting and processing. This can be done using the most ordinary knife, which is designed for construction work, or you can safely use a hacksaw. Choosing a hacksaw as a tool, we recommend taking a tool with small teeth. This is usually a hacksaw for metal. The smaller the teeth, the easier it will be to make the right cut, the edges of which will then not have to be cleaned for a long time.
After the cutting process, the edges require processing. This can be done with the same knife for construction work. You can also use a file that is designed for rough processing. Small files are also suitable, but it is worth remembering that they quickly become clogged with dust from drywall and will not work comfortably. Or you can use sandpaper.
Having completed the preparatory phase, namely, having prepared the hole itself for sealing, you need to decide what exactly you will patch the hole with. The ideal option is a piece of drywall. By the way, after repair it is advisable not to throw away residues and trimmings. As you can see, they may well come in handy.
In addition, for subsequent repairs, namely for repairing damage, you will need the following items: a simple pencil, a ruler, a construction knife, a spatula, sandpaper, slats, screws, putty and drywall itself.
How to deal with damage?
Below are a few ways to help repair a damaged drywall coating. You will be able to choose the appropriate method yourself, since a lot depends on the size of the damage in the drywall construction.
If a small hole is formed with a diameter of not more than three centimeters, then it can be easily patched with putty. Of course, you need putty, which is designed to work with drywall.
When you will putty putty, be sure to read the instructions on the packaging so that all proportions are observed. As a rule, the dry mixture needs to be added to the prepared water, so you can achieve the perfect consistency, which resembles a thick cream.
On the prepared hole, you need to stick the so-called seryanka. Then, a neat layer of putty is applied on top and everything is left to dry completely. The layer should be thin, as the procedure will have to be repeated three times, so that the whole structure is well kept.
After you close the hole with several layers of putty and it is completely dry, the surface must be sanded so that there are no bumps. You can do this with sandpaper. Next, you can already paint the surface or paste wallpaper.
It happens that small cracks form on the surface, which can then interfere with the overall finish. Getting rid of them is very simple. If the crack is small, you will have to deepen it a little, and then cover it with putty, which we talked about above. After drying, do not forget about grinding.
In the event that a small chip has formed on the surface of the drywall, the situation can be corrected with plaster tape. Strip damage in advance, apply tape, and putty on top.
In the event that an impressive damage has formed in the wall, the diameter of which is about or more than eight centimeters, the above method will not work. To fix this problem, you need a "patch".
- Before proceeding with the manufacture of the patch itself, you need to prepare a hole. That is, crop it, giving the rectangle a flat shape. On all sides of the prepared hole, you need to remove two centimeters of cardboard. This is necessary so that later the patch fits as tightly as possible and there is no strong deformation of the wall, bulges.
Hole sealing methods
The method for eliminating a hole directly depends on its size. If the hole diameter is less than 10 cm, one method is used, and if it is larger, another.
Both methods can be used for both wall and ceiling. Defects form on the wall much more often than on the ceiling.
Masking technology will be discussed in more detail below. Keep in mind that the cause of the hole does not affect the process of its elimination. The layout of the drywall sheet can be seen below.
What tools to use
To seal a hole in a drywall wall, the following tools must be used:
- pencil and ruler for measurements,
- sharp construction knife for incising material,
- putty knife,
- construction mixer for mixing the mixture.
As materials will be used: self-tapping screws, a block of wood, a sheet of drywall and putty.
Keep in mind that if a hole has formed in the bathroom or in the kitchen, a moisture resistant coating must be used.
Trim the crumbling pieces around the edges of the hole.
Before proceeding to the sealing of the hole, it will be necessary to first carry out preparatory procedures. These include:
- elimination of the cause of the hole,
- at the edges of the hole you will need to trim all unnecessary.
These procedures must be performed without fail. If extra parts hang on the edges of the hole, you will not be able to patch it qualitatively, and over time the hole will again make itself felt.
Then you can proceed to the preparation of putty or gypsum mortar. The procedure is as follows:
- According to the instructions on the packaging with the solution, add the right amount of water.
- Pour the right amount of material.
- Using a construction mixer, mix the mixture until a sour cream is formed.
Keep in mind that you need to fill the powder in water, and not vice versa. Otherwise, a large amount of sediment may form at the bottom. If the mixture was purchased ready-made, you can start working without the above steps.
