But to lay plasterboard ceilings, you need to have some basic concepts and know something about the subject, if not, it is better to engage the hands of a professional. Here is an explanation of how to lay a plaster ceiling.
Plaster (we measure ceiling meters and buy the gypsum boards we need)
Plaster saw (10 €)
One meter (5 €)
Marking boot in indigo or blue (5 €)
Some nails (1 €)
Esparto (3 €)
Gypsum powder (sold in bags, 4 €)
Fine gypsum powder (sold in bags, 4 €)
Esportón or suitcase for making plaster (10 €)
Hammer (5 € / 10 €)
Drill (30 €)
Wool (10 €)
Spatula (5 €)
A view or a rule
The first We need to be clear at what height we want the ceiling to go, normally it is usually 15 inches from the actual ceiling, but this will depend on how you want it and on the installation of the pipes and cables you want to go through.
When we are clear to what extent the ceiling will go with the counter and pen the mark is made in the corner to the extent that we want the roof to be fenced off. Next, we denote the same sign to the same extent in the opposite corner. And with a marking boot put the two tags we made, we make a line.
That line is right where the ceiling has to go. Indigo or blue boot will mark the entire perimeter of the place where we will put the plaster. For example in the bathroom. Well then We mark the entire perimeter of the bathroom with a marking boot so that we know exactly how high the ceiling is.
Now we look at the real ceiling, if it is a vault or a vault, we hit it with a hammer to make a hole. And if it’s concrete, we drill a hole and install a screw. That’s where esparto will go. If the ceiling is made of concrete, the esparto grass will be attached to the screw, and if it is a vault or vault, it will be attached to the hole we made with a hammer.
Now four nails have been taken and two are nailed to one side of one corner and two to the other, which serves to support the plasterboard, because we have to start from one of the corners.
We have to put the nails a little below the line we marked, so that when we lean the plasterboard on the nails, it is at the level we marked.
The mixture is made between gypsum powder and water, it must be semi-liquid, and we take esparto and smear it with gypsum paste. We put this esparto covered with plaster as follows: One end of the esparto goes to the ceiling in a screw or in the recess of the vault we made at the beginning, and the other end goes to the center of the plasterboard leaning on the nails. Gypsum usually needs a little time to dry, if we want it to dry quickly, we will add more gypsum powder when we mix it.
We already have the first tile on us, now we repeat the same action until we finish the row, and when we have the row, we start making another row from the beginning. With a look or a rule, we check if the others are upright and make appropriate corrections.
We have to drill holes or install screws in the ceiling in all the plasterboard to hold them together. And we also have to put nails in the wall to support the plasterboard. This must be done with each plate.
Obviously you can’t put nails in the middle boards to support them because there is no wall, here we only work using rules or views. We put a nail in the wall, and the other in front and on those nails we support the rule, and on the rule plasterboard. When drywall is held, we remove the rule or sight.
When we have the whole roof, and it is dry, we remove the nails from the wall. Now all that remains is to cover the joints between the board and the board.
To do this, we take a fine plaster powder, mix it with water and make a semi-liquid paste, and cover with a trowel all the joints and imperfections that traces on the plaster and nails may have.
This is a way of applying plaster, it is a bit complicated, but if you are a little close at hand and you are good at these things, you will surely leave a great ceiling.
