plaster, cement-base: composition, types, mixing ratios

Based on the composition and proportions for the preparation of a mixture of plaster can be such types:

cement-lime plaster

main binder - lime.A mixture of plaster of this type made from m

aterials such as lime, sand, water and cement.Grout plaster with the addition of lime is prepared in such proportions:

  • lime - 21 kg,
  • sand - 280 kg,
  • water - 50 liters,
  • cement - 25 kg.
Mechanized and manual methods for applying cement plaster

Scope: plaster walls cement-sand mortar allowed in rooms with high humidity, becauseunder the influence of moisture the plaster does not fall off, and does not lose its properties (ideal for the treatment of surfaces in garages, basements, kitchens and bathroom).

IMPORTANT! cement-lime plaster - one of the few materials that can be run on wood.

manufacturers and materials:

Cement-sand plaster

as the main binder used sand.This type of plaster applied to align the outer facades and other surfaces, as well as to align the internal walls.

Gypsum

This material is similar to the cement-sand plaster.The essential difference - drying time: plaster dries much faster.Gypsum is often used where speed is a dry surface, for example, in the ceiling work.

IMPORTANT! at long term work can not procure a mixture of reserve: gypsum plaster hardens already 30 minutes of cooking!

manufacturers and materials:

Another quality of this type of plaster - plaster "miners", designed for plastering walls and ceilings of brick, concrete, foam and aerated concrete base in rooms with normal levels of humidity.

Specifications plaster:

  • permissible thickness of layers - from 5 to 50 mm;
  • material consumption - 9-10 kg / m² (layer at 10 mm);
  • as dry - 5-7 days;
  • packaging - in bags of 15 and 30 kg.

Price: 9,3 $ / 30 kg.

Other materials based on cement:

to other cement-based materials include a lot of materials, among which are the decorative plaster, cement and perlite mixture and rovniteli.

Rovnitel cement based Bergauf Zement (Bergauf Cement) used to prepare the base, as well as for the application of top coat for all types of coatings.It may be applied by conventional manual method and mechanized.

Specifications plaster:

  • permissible thickness - from 6 to 50 mm;
  • material consumption - 18 kg / m² (layer at 10 mm);
  • drying to touch - 12 hours;
  • maximum curing - 28 days;
  • packaging - in 25 kg bags.

Price: 8,05 $ / 30 kg.

Decorative plaster Cerezyme CT-35 type "pitted" (grain size 2.5 and 3.5 mm) high impact coating for facades and internal wall surfaces, due to its structure allows us to achieve a textured surface indentations similar to wood, proedennye beetle-koroedom.

Stuck Turk walls with cement mortar: what determines the quality of plaster?

for different compositions of cement plaster sets relevant quality requirements: for example, sand plaster should be the minimum grain composition, is acceptable bubble formation on the surface of the mixture, with regard to the basis on which will be applied to this plaster, it should not be visible drops of relief.

Factors affecting the properties of the cement plaster:

  • weather conditions;

work with cement plaster is undesirable at high humidity and at low temperatures.In strong wind or drafts during plaster can cure unevenly and, therefore, crack.

IMPORTANT! If you choose not to, in any weather, plastered external walls are added to the mix shampoo or oily additive at the rate of 5-10 g per 10 liters of ready mix.

  • significant difference plaster thickness;

When plastering the walls with cement mortar wall thickness the maximum difference that can be closed without damage to the topcoat - 50 mm.The desired uniformity of application of the composition, aslower layer hardens faster and the difference in the layers may be formed large cracks in the mass of material.

To avoid cracking the cement surface , observe the operating temperature and proportion of ingredients in the preparation of the solution

  • quality material;

composition of plaster should be uniform and the preparation of additional material to cover one wall, be sure to maintain the aspect ratio of the first composition.Otherwise, plaster may crack, and the joints will be visible two mixtures.

IMPORTANT! quickly wipe out irregularities in the plaster is not recommended.Cement solution takes time, that to stand as follows, for which come from the air and bubbles formed in the interior of the mass.Because after application is necessary to wait about 15-20 minutes.

etching cement plaster neutralizing solution

Plaster will last longer on the surface of the composition does not form a fungus and physico-mechanical properties of the coating will be better if you are using etching.

for etching cement plaster use special solutions containing antacids.

During this type of work on a mandatory basis:

  • use protection in the form of gloves, gown, mask, respirator;
  • etching is carried out only in a well ventilated area;
  • in the case of getting the solution on your clothes or skin immediately rinse the affected area with large amount of running water to room temperature.

etching cement plaster: progress

removed from the walls a coat of paint, outdated wallpaper, dust and dirt of any kind.

components of neutralizing solutions are mixed in proportions and in the manner specified by the manufacturer.

suspension was applied to a wall using a brush or a sprayer.

Wait for drying of the composition (about 15-18 minutes) and wash off with plenty of water.

After that you can start plastering.
