Modern construction intensively uses gypsum plaster as a finishing material, it is simple to install and inexpensive. However, the final cycle, including puttying, requires a special approach and technology compliance.
What you need to prepare for puttying the ceiling from ordinary drywall
The GKL finishing process includes several important stages , the quality of the finish surface depends on the order of priority:
- Reinforcing and sealing joints.
- Finishing putty .
Each stage involves the use of certain materials and tools. If there are no necessary devices, then they should be purchased or rented. Here is a list of tools without which plastering the ceiling from drywall is impossible :
- mixer or electric drill;
- roller or wide brush;
- paint knife;
- capacity for putty;
- grinding grater;
- Lighting lamp on a tripod.
From the materials you should purchase:
- serpyanka (reinforcing mesh);
- primer ;
- aluminum profiles for corners.
Profiles are often found on sale already with a reinforcing mesh, which greatly facilitates the work. Their fastening is carried out directly with putty mortar or stapler.
Anyone who decides to learn how to putty the ceiling of drywall , first of all, must be able to choose the right working mixture. Most of the putty is sold dry , based on natural fillers with various additives. By appointment, they are divided into :
The most commonly used gypsum mixtures with polymer components , they are resistant to moisture and are suitable for leveling surfaces in any room . Before use, you need to add water and by stirring, bring to the desired consistency.
What to do with joints and how to putty plasterboard ceiling yourself
As described above, the technology of leveling the ceiling surface requires adherence to the sequence of work processes. Let's start in order.
Preparation and primer
It is worth checking in advance whether self-tapping screws stick out at the attachment points; all heads should be recessed into the sheet body. In places where the sheets are joined without a bevel, it is necessary to cut off the edges at a 45-degree angle with a knife for a high-quality seal of joints. In this case, it is necessary to check the absence of delamination of the cardboard, and if any, remove it with a knife or sandpaper. The use of a primer when plastering a ceiling from ordinary drywall is aimed at improving the adhesion of finishing materials. As a primer, water-soluble mixtures are used, impregnating the top layer. It is applied with a roller or a wide brush. Drying occurs during the day.
Important! It is extremely undesirable to use alkyd primers - this causes deformation of the cardboard.
Sealing GKL seams
An important point at this stage is the high-quality reinforcement of joints and corners using a fiberglass mesh - serpyanka . The process does not take much time and consists in placing the tape exactly in the middle of the seam. You can do without a sickle, but using Fugenfuller putty , it will cost more, but it will significantly reduce the time of work. Before filling the ceiling with drywall sheets, a solution is prepared . Its volume must be calculated so that it can be used within half an hour . The following processes occur on points:
- with a wide spatula, apply a layer of solution to the area of the joint of the sheets;
- close up the holes from the self-tapping screws with the crosswise movements of the spatula;
- let the solution dry;
- sand the starting layer.
The degree of drying can be controlled by monitoring the disappearance of dark spots on the putty. Particularly pay attention to the absence of protruding parts of the tape, it is advisable not to leave extra irregularities that impede subsequent processing. Grinding is done with an emery cloth with a minimum size of abrasive particles ("null") . The finish layer is applied evenly over the entire surface of the ceiling, while adhering to the rule: the thinner the better. The solution should have a creamy consistency.
For a novice builder, this process can cause certain difficulties, but literally after an hour and a half of work, they miraculously evaporate. The whole problem is that both sides of the corner cannot be aligned simultaneously at once. Therefore, the masters recommend puttingtying the corners of the ceiling from drywall according to a simple scheme :
- to process one side of the corner according to the usual rules;
- allow the seam to dry a little;
- putty the second part of the corner.
Thus, we get an even, neat seam, spending a little time and patience. Aluminum corners with reinforcing tape will greatly help to achieve good results. After applying the finish layer, the surface should be primed again, regardless of whether it is painted or glued with wallpaper.
Tip. When performing work, be sure to use safety glasses, and when performing grinding - with a respirator or gauze dressing.
With a little patience and skill, you can independently arrange the ceiling in your apartment, while saving a considerable amount on the salaries of specialists. And the acquired tool more than once may be useful when doing household chores.
