Seam sealing in the ceiling: preparation
Seam between the floor slabs with a spatula or drill with a special nozzle, damaged and unsuitableCarburization sites are carefully cleaned, freeing the junction of splinters and small particles.
The overlapping surface of the floor is cleaned from dust, after which the primer is diluted according to the manufacturer's instructions. Then, paying attention to the width of the seam, you need to choose the right brush, which will be applied primer. It should be of sufficient width, and the length of the pile should allow the solution to penetrate deep into the joint or crack to ensure the adhesion of the plaster to the surface. After the priming, the seam is dried.
Preparation of plaster and work with it
Dry powder of gypsum plaster is mixed with the amount of water specified in the instruction, after which the mixture is mixed until homogeneous with a construction mixer. To prepare a small amount of plaster, you can use spatulas.
The finished mass must be filled with cracks and voids, in case of a large gap depth it is better to apply the solution several times, before drying each previous layer. If the gaps between the plates are too large and filled with mounting foam, then remove its excess and apply plaster on top of it.
The final stage of the cracking
After the final drying of the plaster all the embedded surface is greased with PVA glue, then it is pasted with a paint tape, forming a gap. On top of it, a layer of putty should be applied, which, after drying, is leveled and sanded with fine-grained sandpaper.
Decoration of plasterboard joints
Gypsum plasterboard ceiling structures are simple to install and are widely used due to the fact that they can create ceilings of any configuration. Giprok consists of gypsum, whose property is expansion at a different humidity, therefore, joints form sheets of cracks. To decorate them, you need to prepare everything you need at the repair stage.
Materials needed
- cutter Brush
- Spatula
- Priming mortar
- Putty
- Sickle
Preparing for decorating
The seam that passes between the gypsum board liners is expanded by cutting a chamfer simulating the factory cutter. To do this, cut the edges of the drywall and slightly deepen the seams. After that, the surface of the prepared seam is cleaned of dust and cardboard residues.
Primer mortar is prepared in accordance with the manufacturer's recommendations. For rooms with a high moisture index it is worth choosing a waterproof primer. Brush the impregnation carefully applied to the entire surface of the joint, after which it is dried.
Sealing
To work, you need to prepare a filler to seal the joint - this is suitable as a ready-made latex putty, which is great for this purpose, and the usual finish mix. When preparing the putty it is worth remembering that for a good work the mixture should be homogeneous, without lumps. With the help of a spatula, you need to collect the necessary amount of mass for the finish and cover it with seams.
After this, you need to measure the specific length of the serpent, which is then glued over the top putty. The surface of the seam is leveled with a spatula, after which it is necessary to wait until the mixture dries completely.
The final stage is finishing work - sandpaper needs to clean all joints, then impregnated with a primer brush to cover all plastered surfaces, achieving the greatest possible smoothness. This type of work will be able to every layman, since the availability of special skills is not necessary.
