Types of technologies- Overview and tips + Video

Types of technologies- Overview and tips + Video Sheets of drywall are quite in demand for dry wall and ceiling decoration.

This material makes it possible to finish surfaces quickly and efficiently at minimal cost.

In this article, we will consider the topic of plastering drywall seams.

[contents ]

Preparation for grouting

Walls or ceilings finished with plasterboard are immediately ready for decorative finishing. This can be, for example, ceramic tiles, wallpapering or decorative plastering.

Usually, when painting or wallpapering, the joints must be filled with a putty.

Filling conditions

Filling should be done at normal humidity and air temperature plus 15 degrees.

Types of technologies- Overview and tips + Video Temperature conditions and other parameters must be observed throughout the installation of drywall, as well as within three days after installation.

Tools

To putty the joints between the sheets, there must be:

  • two spatulas size 25 - 40 cm,
  • drill with attachment,
  • container for mixing mixtures,
  • dry mixture for preparing putty,
  • reinforcing tape.

Putting on the seams is easy, but it takes patience.

Preparation of the putty mixture

The putty is prepared strictly according to the instructions indicated on the package. Before buying a putty mixture, pay attention to its expiration dates.

Many dry putty mixtures contain gypsum powder, which has a habit of absorbing water.

Types of technologies- Overview and tips + Video If the expiration date of the putty mixture has expired, then it loses its properties and it is better not to use it.

The mixture is prepared by adding the required amount of water to the dry mixture.

After adding the liquid, the mixture is thoroughly mixed using a drill with a mixer attachment.

Stirring is best done at low speed and stirring until the mixture is homogeneous, without lumps and lumps.

The ready-made mixture must be used within twenty, forty minutes, for this reason the solution must be prepared in small portions in order to have time to use it.

Sealing the joints

How to seal drywall seams with putty and serpentine?

Preparing the edge of the gypsum board

  1. Types of technologies- Overview and tips + Video The joints between the sheets are filled with a reinforcing tape gasket.
  2. It is pressed directly into the putty.

  3. The edges of the drywall sheets are thinned to form the seams.
  4. Before starting the installation of drywall, chamfer one third of the sheet thickness at an angle of 45 degrees.
  5. After fixing the sheet, cut the cardboard equal to the width of the hidden joint.

Working with the seam

Applying the mixture

Then, a layer of putty mixture is applied to the area of ​​joining the sheets with a spatula, leveling in one motion and remove excess.

Reinforcement

The next step will be the laying of reinforcing fabric (serpyanka), it is pressed into the putty.

Next, take a wide spatula and apply another layer of the mixture and smooth it out well. After the seams are dry, they are traversed with fine-grained sandpaper.

It must be remembered that the next applied layer of putty should be 50 mm wider than the previous one.

Types of technologies for filling joints

The filling of joints between sheets of drywall is produced, of course, according to technology. It is determined by what types of edges the drywall sheets will be used with.

Selection of technology depending on the edge of the board

Types of technologies- Overview and tips + Video When using either For a different type of edges, there are some recommendations that ensure the strength and quality of the joint.

There are gypsum plasterboards with beveled edges

Such sheets are putty using serpyanka. Such seams are closed in three stages, this requires a lot of time. For this reason, to reduce labor and time, plasterboard sheets with semi-circular lengths have been developed.

Plasterboard sheets are available with semicircular edges

Plasterboard sheets with such edges can be putty without using a serpyanka.

The filling of sheets with such an edge occurs in two steps, but there is one nuance that must be taken into account, and this is that for filling work, it is necessary to use only mixtures with high strength.

There are gypsum plasterboards with beveled edges

Not so long ago, drywall sheets have a beveled edge along the length.

This type of edge allows the use of both technologies that we described earlier. For this reason, these sheets are considered universal, at the moment they are more in demand.

Technologies in reinforcement

Why is surface reinforcement necessary?

The joints of sheets laid with reinforcing tape are not subject to cracking .

..

The advantages of the reinforcing tape are that no air bubbles form during its application, and it also does not change its shape during priming, painting.

Types of technologies- Overview and tips + Video Working with a reinforcing tape requires a certain skill.

Paper tape

To achieve special strength of joining sheets of gycardboard, paper tape is used.

It is used to design internal and external corners and joints, which require special strength. For example, when covering attics.

Fiberglass tape

Fiberglass reinforcement tapes and paper tapes are necessary to reinforce horizontal seams because their imperfections are visible under light. The above examples have high priority over self-adhesive reinforcing mesh. Because the thickness of the self-adhesive mesh is small.

Types of mixtures

Types of technologies- Overview and tips + Video Different types of edgebanding also require different filling techniques and different types of putty mixtures.

In the production of putty mixtures, there are two types of them:

  1. Based on gypsum binders;
  2. Based on artificial binders.

Application technology is determined by the characteristics of hardening.

So we have analyzed the technology of filling joints for plasterboard surfaces. We hope that our article was useful to you.

We wish you good luck in your endeavors!
