Finishing plaster walls - the efficient completion for a better start

Finishing plaster walls - why is it necessary?

If not so long ago, the question of registration of the walls was solved quite simply - on old wallpaper pasted new and existing cracks and uneven gloss over putty locally, now increasingly talk about the technology of surface preparation of the walls to their final finishing.In particular, we are talking about finishing shpaklevanii.The main purpose of finishing putty is such a wall decoration room, which allows you to get the maximum quality and level of their surface for subsequent processing.

can use it to disguise the smallest defects or irregularities of the walls, remaining after application of the base leveling layer.It is impossible not to draw attention to the fact that the finishing composition, as opposed to the base, has a pure white color.This allows the use of thin white or any color wallpaper safely.The possibility of obtaining a fairly smooth surface of the walls due to the small size of the filler fractions.This is particularly important in the event that the wall is planned paint as paint is able to conceal the presence of irregularities.

On top of that the finishing composition provides good adhesion (adhesion) of the wall with an adhesive layer.This feature allows you to rely on the fact that the final finishing will serve you for a long time without risking to fall off the wall. Experts recommend not to neglect this type of filler, and when prepared for final finishing plaster or foam concrete surface.They are sufficiently porous and absorb moisture well, so complementary and reinforcing wall layer will not be superfluous. Thus, the need for finishing putty is obvious, but how to choose it?

Caulking finish types - how to choose?

First of all, you must pay attention to its structure.Today on sale there are several types of finishing fillers that differ in the type of binder.The greatest attention should be given polymer, gypsum and cement compositions.Each has its advantages and disadvantages.Thus, the cement composition differs excellent resistance to moisture, which can be used in rooms with high humidity (bathroom, kitchen).Can be made on the basis of both gray and white cement, to which you should pay attention when buying, because it is cement color determines the color of the treated surface.Cement finishing coat, also called the facade gives a small shrinkage, so often requires the application of several layers.

Gypsum plaster finish different types of snow-white, eco-friendliness, affordability, but unacceptable for use in wet areas.In addition, it does not tolerate sudden changes in temperature.In this case it is not subject to shrinkage and is suitable for handling most surfaces (bricks, concrete, gypsum board, etc.).Highest quality topcoat provides polymer compositions.Due to special additives, they become malleable and easily applied to the surface of the walls without creating problems when leveling.Of course, the cost of such fillers is quite high.

As already noted, the quality of the finishing composition is determined by the size of its aggregate fractions: it is less than, the smoother will be the surface of the walls.Fillers with a grain size of up to 0.15 mm do not even require subsequent grinding.

Such formulations are ideal for the preparation of walls for further staining.If your plans include wrapping the walls with wallpaper, you can choose the putty with a grain size of 0.5-0.8 mm.When choosing the finishing composition is recommended to pay attention to its viability - the period of time during which the plaster retains plasticity in an open container and is suitable for the job.Usually, it takes 2-5 hours, even faster freezes plaster to pour cement compositions.But the composition of the polymer retains its plasticity to 24 hours.So, the choice is made, it remains only correctly apply the putty on the wall, but even here there are some nuances.

Finishing putty walls - keep applying technology

finishing putty is applied on clean, leveled and primed surface of the wall.To apply you will need containers to dilute the composition, small (10-15 cm) and a large spatula (40-60 cm).A small spatula is used to intake the required amount of putty from the container and transfer it to a large spatula, by which then carried out the composition of leveling the wall. Coating thickness is typically less than 1-1.5 mm, since thicker layer stacking is great risk of cracking and fraying.

Experience shows that a single layer of finishing filler is sufficient if the finishing coating will be vinyl or non-woven wallpaper.If the walls will be painted, it is recommended to put structure into two or even three layers.To lay the finishing composition of the joints in the wall surfaces using a trowel or spatula corner.As for the application of putty on the wall, then you have two options.The first involves leveling her pretty broad strokes in the direction from left to right or bottom to top.

spatula pressed against the wall at an angle of approximately 20 °.When applied with a spatula spend several times in one and the same place, capturing a new area gradually.

Do not be confused by the presence of irregularities on the instrument, since they are easily removed during subsequent grinding putty.The second option - the application of leveling compound with small sharp strokes.It's pretty hard work, assuming the secondary coating the surface of the leveling layer, but the result is worth it.You can completely ignore the grinding wall, even if it is supposed to be painted.Thus, the finishing plaster walls, a video of the application which can be found on our website becomes a real lifesaver in the repair work.
