Gypsum plaster "Prospectors": characteristics and application

Among the many building mixtures, many professionals stand out gypsum plaster "Prospectors". It is designed for high-quality processing of walls and ceilings in rooms with low air humidity and is characterized by excellent consumer properties in combination with an affordable price.

The basis of the plaster is plaster of paris. The composition also includes special mineral additives and fillers, which ensure high adhesion of the solution and significantly reduce its consumption. The mixture has good heat and sound insulation and is great for living rooms.

Plaster "Prospector" is also able to regulate the air humidity in the room.... Due to its hygroscopicity, it absorbs water vapor from the air, thereby reducing the relative humidity. If the air is dry, then the moisture evaporates from the plaster and the humidity in the apartment rises. Thus, a comfortable climate for humans is created in the living space.

The solution is easy to apply and works well. The plaster is flexible and does not crack when dry. It is intended for indoor areas with low humidity. The composition does not have water resistance, so you should not use it on objects with high air humidity and where the walls may come into contact with water.

The Prospector mix can be applied to brick, concrete and other hard surfaces. In addition to interior decoration of premises, it is used as a basis for decorative compositions and putty mass. Plaster can also be used to fill joints and cracks in surfaces to be treated. You can also apply it in a thick layer up to seven centimeters.

After applying "Prospectors" you can not use putty, thereby saving a lot of time and money. Low consumption of the mixture, strength and elasticity of the resulting surface, low price - these are the main advantages of the plaster mix "Prospectors".

The mixture is available in paper bags weighing 30 or 15 kg. It can be white or gray, depending on the properties of the gypsum from which it was made. Sometimes a pink-colored composition is sold. Before use, the mixture is diluted with water, after which it is applied to a dry, well-cleaned surface.

Mixture specifications:

• plaster is intended for indoor areas with low air humidity;
• the plastered surface can be used for painting, for applying textured wallpaper, under tiles and finishing putty;
• on average, 0.9 kg of plaster is consumed per square meter of surface;

• the temperature range at which the mixture can be applied is from +5 to +30 degrees;
• you need to use the resulting solution within 45-50 minutes;
• the thickness of the applied layer can be from 5 to 70 mm.

If bases such as foam concrete, drywall, brick, plaster are processed with the mixture, then they must be pre-primed. It is desirable to treat other surfaces with the "Concrete-contact" primer.

First, the mixture must be diluted. To do this, it is poured into a special container, then water is added at the rate of 16-20 liters of water per package or 0.5-0.7 liters per one kg of dry mixture. Use clean water for diluting the plaster. The mixture can be mixed with a mixer, an electric drill with a nozzle or manually. The solution should stand for 5 minutes. The resulting solution should be homogeneous, after settling it is stirred again. After that, you can start working.

Do not add water or add dry powder to the finished mass. In 50 minutes, you need to have time to use the resulting solution.

The mixture can be applied manually or mechanically.

To do this, use a spatula or trowel. The mixture is applied in several layers, moving the tool from the bottom up. For the first layer, it is better to use a coarse-notched trowel: it will provide better adhesion. After application, the surface must be leveled. The thickness of the applied layers is no more than 5 cm.

The ceiling is plastered by moving the trowel towards you. Apply only one layer of the mixture. The solution is set in two hours. If the layer is more than 2 cm, then reinforcement with a metal mesh must be used. After 40 minutes, the solution sets, after which you can cut off irregularities and rub the surface with a spatula.

After the applied layer has dried, the surface can be prepared for final finishing. To do this, the plaster is moistened with water and rubbed with a float. Then smooth the plaster with a wide spatula. Smoothing can be repeated after a few hours. After such treatment, the surface can not be putty.

For machine application of plaster, a gun is used, moving it from the upper left corner down and to the right. The mortar is applied in strips 70 cm long and 7 cm wide. The strips must be overlapped with the adjacent one. Plaster is applied in one layer.

The ceiling is plastered with movements from left to right, starting from the wall farthest from the window. The thickness of the layer depends on the speed of the gun: the higher the speed, the thinner the layer. The recommended thickness is no more than 2 cm of mortar. The ceiling must be pre-reinforced. In the future, the surface is treated with a float and a spatula.

• For outdoor use produced cement-sand mixture "Prospectors". It is also used to work with the basement of a building. The mortar can be applied to old plaster. Produced in 30-kg bags, about 12 kg of the mixture is consumed per one meter of surface. When working with it, there are no restrictions on air temperature.
• Plaster "Bark beetle"... Decorative finish, suitable for exterior walls. The composition includes dolomite chips, which creates a grooved surface pattern. Then the plastered walls are painted.
• Optimum. It is used for rooms with high humidity. The composition includes cement, which ensures the water resistance of the coating. It is used for external and internal surfaces. Application in a layer up to 9 cm thick is permissible.

The price for plaster "Prospectors" is low and quite affordable. The cost of one package in different stores ranges from 300 to 400 rubles for a 30-kilogram bag.

Reviews of the plaster "Prospectors" are generally positive. Buyers note the low price and low consumption of the mixture per one meter of surface.The mixture is easily diluted, the solution is homogeneous, without lumps.

The applied layer of plaster dries without subsidence and cracks, it is well processed. After double processing, the surface is smooth and does not need putty. A slight disadvantage is that the pot life of the solution is about 50 minutes. But this feature is present in all mixtures prepared on the basis of gypsum.
