Today we will consider the features of the textured plaster device, methods for diluting the mixture and the list of ingredients used in the composition. In addition, you will learn what tools you need to apply the plaster layer, as well as familiarize yourself with the technology for applying textured plaster..

Preparing the walls

Textured plaster is a topcoat, so it should be applied only after other work in the room has been completed. For the device of textured plaster, there is no need for careful preparation of the walls, as when wallpapering or painting, irregularities within 2-4 mm are quite acceptable.

We level the walls, plaster, putty, then prime with a penetrating primer using a wide brush or roller. Leave to dry for 2-3 hours. This will help to strengthen the surface of the wall and keep dust free. Any acrylic primer will work, such as Ceresit. It is odorless and non-toxic.

Tip: Before applying the primer, be sure to cover the floor with a film, traces of the primer are poorly washed.

Dilution of the plaster mixture and its composition

We start plaster dilution. 6–7 kg of white gypsum-based dry plaster are poured into a container of a suitable size. Any one will do, such manufacturers as “Hercules”, “Kreps”, “Rotband” and others. It does not shrink, does not crack when dry, is very flexible and easy to form.

Add 2-3 liters of water to the dry mixture and mix with a special drill attachment at low speeds until the mixture becomes homogeneous and resembles sour cream.

Add PVA glue for construction work to the finished mixture to increase plasticity and slower setting of gypsum plaster at a rate of 10: 1.

Application methods and tools

Gypsum plaster tends to set very quickly, so you need to start work very quickly and try to work out the entire composition at once. As soon as you notice that the composition began to lose elasticity and began to set, it is permissible to add a little water and stir.

To form the necessary texture of the surface of the plastered wall, you can use either special tools with various shapes in the form of teeth, comb, brush or imitation of reptile skin, or improvised means: sponges, brushes, a plastic bag and just hands with gloves.

Textured plaster is applied to the wall with a wide spatula with a layer of 4–6 mm and is slightly leveled. Immediately on the applied area, we form the texture using the selected tool. If it is a comb or brush, then they need to be drawn along the plaster in wavy or even lines. It is not necessary to press the tool into the plaster strongly to avoid the appearance of deep grooves reaching the wall.

Finish coating

When all the plaster is applied, we leave it for at least a day to dry completely. Plaster can be painted with any water-based paint with the addition of a color of the required shade. It is imperative to paint over the plaster, since even white gypsum, after application and drying, has a grayish tint.

If you need to get the effect of two colors, then after the first layer of paint has dried, a second layer of paint is applied with light pressure with a sponge, usually of a darker shade. You can also add a dye with a gold or silver glitter effect to the paint for the second coat to create a shimmery effect of the wall in different lighting conditions..

If you want to get an individual interior in your home that will have no analogues anywhere else, then do-it-yourself textured plaster is the best option..
