How to apply plaster

There are three types of monolithic (ordinary) plaster. Simple plaster has two layers (spray and soil), its thickness is 12 mm. Improved plaster has three layers (spray, primer and cover), the thickness of this plaster is 15 mm. High-quality plaster has a layer of spray, several layers of soil and a layer of cover. Its thickness should not exceed 20 mm.

Before applying the plaster, it is necessary prepare the walls. They are removed from any old finish (tiles,wallpaper, whitewash). Clean the walls of dust, dirt, etc. If there is an old plaster, check its strength by tapping the plastered areas. Old old plasters should be removed.

Before applying the plaster, the surface of the walls needs primed. The reinforcing primer is applied with the help ofpaint roller and brush. The roller is used to apply the primer evenly to the wall surface, and the brush is used for hard-to-reach places. If the surface has good absorbent properties, several primer layers must be applied.

Then dilute dry plaster mix. In residential areas it is better to apply plaster ongypsum base, and in rooms with high humidity - on cement. Gypsum solution is not advised to be applied to concrete walls; it is better to give preference to the lime solution.

Dry plaster is diluted in accordance with the instruction manufacturer. Use clean water to make plaster. To mix the plaster mortar, you can use a mixer for an electric drill. If the solution is too thick - add water to it. If the solution is excessively liquid, put a brick in it - it will absorb excess moisture.

Then you can start to apply plaster. We will talk about applying improved plaster, simple and high-quality plaster are applied in a similar way, all the difference in the number of layers. To apply plaster it is necessary thin layers, differently at drying it will burst. The thickness of the total layer of plaster depends on the material of the walls: up to 5 mm for concrete, 5-10 mm for bricks and at least 20 mm for wood. The smoother the surface - the less the layer of plaster.

The first layer of plaster is splashing. Stucco solution must have a creamy consistency. The solution is thrown on the wall by a continuous layer, there should not be any gaps. Spray is needed to fill the unevenness.

Priming - this is the main plaster. The consistency of the mortar for the soil is more dense and resembles a dough. The layers of soil can be several depending on the desired thickness of the plaster and the degree of unevenness of the surface. Each layer of soil (especially the last one) must be carefully leveled.

The third layer of plaster (covering) has the same consistency as the spray. The cover is applied to the wet ground - it must be able to grasp, but do not have time to dry. This contributes to better grip. The dried up primer and the covering are moistened with a brush.

After applying the coating, the plaster is rubbed. Grout produce on grasped, but not dried plaster. Grout is made in a circular motion with a wooden float. After complete drying of the plaster, it is grounded, and putty is applied from above.

Setting time of plaster depends on the composition of the plaster solution,the porosity and humidity of the walls, the air temperature and the thickness of the plaster layer. Lime-gypsum solution was grasped for 7-15 minutes, grout - after 2-6 hours. The plaster must not be dried using heat: it begins to crack and fall off. It's better just to ventilate the room well.

Applying plaster must necessarily with observance safety rules. Before applying the plaster, remove from theplastered surfaces all nails. If you put plaster on top of reinforcing mesh, do not forget to wear protective goggles: when applying plaster, the mesh can vibrate, then the solution will begin to fly off, and there is a likelihood of getting a solution into the eyes.

You can apply plaster not only to level the walls before painting or wallpapering, but also as decorative coating. For example, Venetian stucco looks very profitable.
