Increasingly, the creation of modern interiors uses plaster panels and plaster tiles imitating natural stone or brick. Cheapness of the material, ease of installation and beautiful appearance makes such finishing material very popular. In addition, it is eco-friendly and non-combustible.
In the stores there are various variants of plaster tiles. If you made the decision to decorate your apartment or house with such panels, it makes sense to go and see what they look like on the wall. It will allow, will decide on appearance, and returning home to begin to make the dream come true.
You will need moulds under tiles, gypsum, water and paint to begin the work. The finished moulds are sold in the store, but as a trial step it is possible to take any form, even for biscuit molding.
Before starting work, it is necessary to remember that gypsum is very volatile and to deal with it on the draft is problematic. Will fly all over the room and lie in a thin layer on all surfaces. Erasing it then will be very difficult. Sold plaster in paper bags and after opening the bag may be torn more than necessary, so it is better to place it in a plastic bag in advance. Like from under the garbage. The cleanup will be a lot less.
A bucket can be taken as a container for kneading gypsum. Here everything depends on the volume of the mixture and the area of the poured surface. Knead gypsum with stock should not. It stiffens up pretty quickly and gets messed up. Water used for gypsum breeding should be cold, it allows to increase gypsum stiffening time. With rapid stiffening, there may be a situation in which the plaster mixture does not have time to fill the entire space of the form or the air caught in the mixture will not come out.
gypsum mixture should be prepared at the rate of 0.7 liter of water per 1 kg. gypsum. The water temperature should not be higher than 18-20 degrees. The speed of gypsum stiffening when kneading with hot water will be only a couple of minutes. In such a short period of time you will not even have time to mix the mixture qualitatively.
Before pouring, the mold should be lubricated with oil or soap solution. This will allow easier separation of the product. The consistency of water-diluted gypsum is similar to liquid sour cream, but after pouring into shape, the gypsum begins to harden quickly. This process involves heating, so don’t freak out. Immediately after pouring the shape or surface on which it stands, you should be subjected to vibration. This will allow the gypsum mixture to be evenly distributed throughout the shape and to squeeze out excess air.
initial gypsum stiffening time is up to 20 minutes. But that doesn’t mean that the product is completely ready. After being excavated from the mold, it will need a few more days for the final strength set. Then the finished panel can start to paint and varnish.
