Why putty the ceiling?
Before covering the topic of how to properly putty the ceiling, you need to find out the feasibility of this stage of construction. Such work gives the following results:
- evens the surface and color, eliminating cracks, bulges and yellow spots, which is especially true if repairs are carried out in houses of old buildings;
- reduces paint or glue consumption of the finish coating;
- facilitates decoration;
- hides tile joints or traces of self-tapping screws if plasterboard is putty.
The choice of putty
Putty is classified by readiness for use:
- The finished product. The composition is sold in hermetically sealed buckets. The product does not require preparation and is used immediately after opening the package. Ready putty is recommended for people who do not have the skills of professional builders, because the product does not need preparation and is easy to apply, which reduces the time of work.
- Dry mix. Sold in paper bags as shown in the photo. The mixture is a dry powder that is diluted with water and kneaded with a drill with a special nozzle called a mixer. Only with this tool you can achieve the desired density of the composition. The advantage of putty is low price, the disadvantage is that it requires preliminary preparation and additional equipment.
Putty is also classified, depending on the stage of construction:
- Coarse product. Recommended for use as a starting surface treatment to eliminate defects.
- Fine-grained mixture. It is used to level the building foundation before finishing.
The choice of putty also depends on the climate of the room in which the work is carried out. If construction takes place in a dry room that is well heated, it is recommended to use mixtures containing gypsum and polymeric substances. For rooms with high humidity suitable waterproof product, which includes cement.
Necessary tools and materials
Tools and materials that will be required to complete the work:
- putty in finished or dry form;
- primer (it is recommended to use a deep penetration composition);
- a bucket and a drill with a mixer nozzle if a dry product is used;
- set of spatulas;
- tool for applying a primer (roller, spray or brush);
- sandpaper to smooth the surface;
- reinforcing mesh (if putty is not applied on the ceiling of drywall).
Shelf putty rules
Ceiling putty consists of several stages - preparation, application of starting material, topcoat and grout. The instruction manual is simple, but requires careful study.
Surface preparation
Before finishing, the surface is prepared for work. The old coating is removed - tiles, whitewash, etc. Next, the ceiling is freed from dust and dirt.If liquid was used, then the surface is left for some time to dry. Then a primer is applied. It is recommended to put two layers. After that, the ceiling is checked for defects. If any are found, the surface is plastered. After that, you can proceed to the next stage of work.
Starting putty
To apply the starting layer of the material, coarse putty is used. The solution is kneaded according to the instructions indicated on the package. After that, a spatula is taken, and the composition is applied to the ceiling. The layer should be even, because the quality of the application of the putty and finish depends on this.
Finishing putty
The finishing putty is applied after the first layer has dried. Before using the material on the surface, it is recommended to use a wide trowel to level the building foundation. After this, a second solution is kneaded. For this, fine-grained putty is used. It better aligns the surface and prepares the base for further finishing. The ceiling is treated with the resulting composition. If the finish is painting, then the putty is applied in two layers. In all other cases, a single layer is sufficient.
Grinding
When the finishing putty has dried, the ceiling is sanded. It is recommended to perform the work wearing protective equipment - glasses and a respirator. After that, the surface is treated with sandpaper. Then a primer is applied to the ceiling and the finish is done.

Putty plasterboard ceiling
How to putty the ceiling of drywall - this question arises not by chance from lay professionals. The rules of work for this base are slightly different from the putty algorithm of other surfaces. Drywall ceiling does not need alignment. Its surface itself is flat and free from defects. This simplifies the work a little, but there are some nuances.
Answering the question of how to properly putty the ceiling from drywall, you should consider the algorithm of work:
- A primer is applied to the surface. The joints of the sheets are carefully worked out.
- All screws are screwed so that the cap does not extend beyond the base. After that they are putty.
- Putty is applied to the seams. On the long side of the sheet, this procedure is not carried out. For work, starting putty is used, which is applied to the seams. After that, a reinforcing mesh is applied to the composition, which is pressed into the composition. It is recommended that a trowel be used to level the surface. Next, another layer of putty is applied to close the mesh.
- When the putty dries, the surface is sanded. To do this, use sandpaper.
- The surface is primed. The composition is applied in two layers.
- After the primer dries, the entire ceiling is treated with putty. The finishing mix is used. After drying, the ceiling is also sanded.
Knowing how to putty the plasterboard ceiling correctly, the work will go quickly and if everything is done right, then the finish will last a long time.
The ceiling putty algorithm can be mastered by everyone who is not directly related to construction. This will save on the work of professional masters and learn a new skill.
