Granite marble plaster

Granite marble stucco is a beautiful and inexpensive facade decoration of almost any room. It is used both for interior and exterior decoration. Today you will get acquainted with this material in more detail, decide how much it will suit you. The video in this article will show additional and necessary information.

Composition, characteristics and application

Stucco with granite chips has the necessary components, without which the result of the work will not bring the necessary results, which is why the presence of such substances as: filler, astringent mixture of the substance, also the solvent is mandatory.

Granite decorative plaster and its features

Attention: If granules made of marble are taken as a filler, then in the end we will get decorative plaster with simply amazing effect with marble chips as a base.

So:

• Significant competition for artificial stone made up a natural material with small fractions - that is, a crumb with a certain size, which in such mixtures is necessarily present in the composition, which is created on an adhesive material, also with a variety of acrylic additives.
• There is an abundance of natural colors and shades of the filler, and the color itself plays thanks to different lighting.
• Varnish coating enhances the visual effect. The method of use, which is directly dependent on the characteristic size of the crumb itself: large crumb for use in outdoor works with facades, fine-grained - for interior decoration. Gorgeous in this design look door openings, window frames.
• When buying granite plasters, you need to pay attention to the fraction of the composition: coarse-grained is a crumb of 3-5 mm, fine-grained - 0.5-1 mm, fine-grained up to 0.5 mm. And in order to determine exactly which particular group the purchased material belongs to, then pay attention to the accompanying documents to the material, there is an instruction with instructions and characteristics.
• Binder acrylic composition is characterized by elasticity, resistance to the emergence of microorganisms, to the formation of cracks, the inability to peel the surface.
• A plain or mosaic texture will emphasize the necessary elements of the building, for example, arches (see Decorating the arch with mosaics: how to do it yourself), cornices, various niches and openings, will create an emphasis on the most presentable parts of the structure.
• Creating surface zoning by creating a color shift at different facade levels can distract the focus from all kinds of defects on the walls. The smaller the amount of work when applying plaster, the better will be the result at the end.

Main characteristics

Granite decorative plaster is served in the form of crumbs, which can be bought or ordered, used for walls of any type and type, for example, created from foam concrete, concrete; on drywall, also on ready-made plasters, on any coatings.

• Fundamental coating It is resistant to various mechanical influences, including ultraviolet rays, to the effects of water. It has excellent vapor permeability due to the porous coating.
• Also, this material is quite durable. and you don’t need to spend money on its content.
• In case of violation of the application technology, for example, if you save on primer work (seeWhy do we need a primer: technological nuances of finishing work), the coordination of parts of the metal structure on which the plaster is directly applied is enhanced.
• High adhesion ensures setting.that is applied to the external walls, but if there is a need for repair, it becomes necessary to update the entire facade, rather than individual parts.

Finishing the facade with marble chips

Granite decorative plaster is completely applied with your own hands, then the final price will be much lower. Only when performing work, it is necessary to observe the application technology, this will be the key to the quality and durability of the coating.

Manual application

Attention: It is the preparation that largely determines not just the appearance of the coating, creates a foundation that will be the foundation of durability.

So:

• The preparatory phase is always required before starting any type of work, since for execution it is necessary to order the necessary instrument (seeWall plastering tool: what you need to work), and purchase raw materials: choose the crumb itself, choose the composition for the primer, a spatula that has a wide base, and which is used to comfortably apply the mixture itself, also a smaller spatula to carry out the process of applying the main plaster to the spatula, pick up a specific brush and roller for the implementation of the primer, purchase and grater of metal.
• Now remove the old coating. Then stopping is carried out using a cement mixture. The surface itself, but already dry and prepared for subsequent work, is cleaned, freeing from the possible presence of dust and dirt. Of importance is the fact that the humidity of the surface should not be more than 5%.
• If it becomes necessary to tint the composition, order a dye of a suitable color shade, which is added before application, which helps to avoid different tones for all finishes with marble chips. The most relevant is the application of soil to plaster, as well as walls finished in brick.
• In suspected places where a problem may arise, the base itself sticks together, which prevents the penetration of moisture directly into the walls. Acrylic primer with deep penetration is applied with a paint brush or using a roller, and after the first ball has completely dried, it is treated again to achieve the strength of the supporting structures and to prevent peeling of the lining. The façade, ready for plastering, should be roughened to prevent difficulties in application.
• A surface that has already been repeatedly run before must dry, and then directly begins the application of marble chips to the facade.

Attention: The work must be completed at a time, otherwise the surface will be visible when the sun is shining, the borders of precisely those areas over which decoration was performed at different times.

• First we take a wide spatula and then decorative granite plaster is applied to it with a smaller spatula. After that, the composition is evenly rubbed along the wall, the layer of which is equal to the thickness of the fraction of a unit of marble.
• 30 minutes after finishing the whole, then drying, the surface itself is treated with a grater in one direction and at a steady slope to the wall until the entire facade is aligned. Exclusively due to this, a high-quality finish is created, and the material itself is evenly applied.

Mechanical application

The use of a pneumatic crusher that is capable of throwing crumbs will help make the process easier and faster. This is a simple device, which consists of a reservoir for the mixture, the nozzle that is located at the bottom.

Application of marble plaster with a compressor

• The nozzle itself, together with a special nozzle equipped with a spray gun, creates a shape, also a thickness for the produced jet, then the air pressure is pumped by the compressor, then it goes into a metal tube connected to the tank with a mixture of plaster from the opposite end.
• Shut-off and sorting fittings, or rather, a small-size mounted crane, feeds air. This helps to regulate the pressure with which the mixture is supplied.
• First, we prepare the surface - level it, clean the dust, contaminants by applying an adhesive solution, which we repeat again in 2 hours. Give a color tone.
• To improve the adhesion of stucco with marble chips, there is basically no need to dry the entire second ball, and on a slightly dried surface using a crusher, mix with granules from top to bottom. It is necessary to keep the nozzle 50 cm from the wall, and keep the pressure uniform - this is the only way to achieve a normalized flow, deep impregnation of adhesive components into the very structure of the walls.
• So that the texture is high-quality, the crumb is deepened into an elastic adhesive solution. We are waiting for the mixture to harden and cover the facade with a thin layer of the composition of the strongest organosilicon varnish, which will become a protection against deformation and destruction for the finish layer.

When the color of natural chips does not fit, it can be painted with any color, and the resistance of the coating itself to various influences will increase - to mechanical, to shocks, to fading under the sun.

Take note of the following:

• The necessary color can be achieved by using a variety of colors for decoration. It consists of natural components, artificially tinted paints, which can be of mineral or organic origin. Such a wide range of colors provides virtually unlimited design variations.
• Having picked up marble chips in the facade of your own home, read the instructions for the work, order or buy goods such as plasterboard sheets, the entire tool, a trial part of the mixture for training application. Only after we start work on a full scale, and you will not be afraid to spoil the design of your home, because you will have time to fill your hand.

Granite marble plaster will serve you for many years only if you use high-quality materials for work. Therefore, when buying, pay attention to the manufacturer. So you can see the photo and select the desired pattern, and after that, take your time to get to work.
