Plaster walls and ceilings made ​​of gypsum - how to quickly and reliably ?

What is the material and what it is used?

Building plaster (stucco) is an environmentally friendly, natural finishing material.Due to the properties quickly grasp, it is used for the installation of electrical cables, for the manufacture of such fillers, such as gypsum putty to install beacons in the plaster, puttying holes, production of sheets of drywall.On the strength of it is divided into three groups:

• Grade 1 - compressive strength - 5.3 MPa;
• Grade 2 - limit is not less than 4.5 MPa;
• Grade 3 - limit of not less than 3.5 MPa.

This material in the dried state "breathe", that is, when the room is too much moisture, it absorbs it, and when it is not enough, on the contrary, gives.This makes gypsum natural regulator of the level of moisture in the room.At different temperature processing material it receives a variety of properties and shares in the building, molding, vysokoobzhigovy and technical.

Gypsum Plaster works necessary for the hardening rate of the mixture.So, if you use three pieces of plaster and one part of the filler, the mixture is quickly set.The exact proportions of the mixture of gypsum putty is not, so it is done empirically.

Secrets of cooking

Using the gypsum plaster, it is necessary to take into account its rapid solidification, and that when mixed with water, it expands and heats up.Plaster mixed with water, forms a dough that is as dry becomes stronger.solidification point comes in four minutes, and it hardens completely in six minutes.

for his mixing is necessary to take two pieces of plaster and one part cold water.It is important to pour the water first, and then, while stirring, add gypsum.The finished mixture is not suitable for storage, so it must be all right to use.The dry material is stored in tightly closed containers, in order to limit air infiltration.The recommended shelf life of three months, as, after this time, it begins to lose its quality.

Note!Tightly closed from the air is especially necessary to keep the wet plaster, as it has a very low water resistance.To make

curing process is so intensive, it is necessary to add from 0.5 to 2% of animal glue soluble in water.He is able to slow down the curing process, but not for long.You can also add lime mortar.Many people applied for this purpose an ordinary washing powder, dissolve one teaspoon per gallon of water.

Regulations quality work

If you have chosen the plaster as a material for plaster, the question arises as gypsum plaster?In principle, the work does not differ with him from working with any other filler.The only thing that you must always remember is that he quickly grasped, and so should work quickly.Often this material is used for alignment of walls and ceiling.Align gypsum walls in the following order.

first step is to check the condition of the surface.All loose and movable elements on the surface will lead to flaking plaster, so they are fixed or removed.If you repaired the old plaster layer, the damaged areas completely astray, and the wall beneath them trimmed.

Remember that gypsum is corrosive to metal elements, so that all such items must cover the corrosion solution.Plaster walls plaster necessarily require pre-surface primer.Also necessarily secured fiberglass mesh at the junctions of different materials (ceramics and concrete, etc.).

Decorating the walls with plaster can be done both manually and by machine.Focusing on the type of application, prepare the solution, each of which has its own type.The plaster mixture hardens quickly, so by the wizard requires precise organization of work and experience.Solution was applied in a single layer, but if there is a strengthening nylon mesh, then another layer.

applied to the ceiling light solutions, and the layer thickness should not exceed 15 mm.The walls are plastered heavier composition, and thickness should be no more than 20-25 mm.If you do not have experience with this material, it is better to entrust it to a specialist.
