Ordinary non elastic exterior wall emulsion paint (1) only has the function of cleaning and beautification.

Production process of real stone paint.

It is generally used in high-rise main walls and other auxiliary rooms in medium and low-grade parks.

Forming mechanism 2.

Genuine stone lacquer is mainly composed of emulsion.

Real stone paint has good decoration, wide application, simple construction, water-based environmental protection Good weather resistance and other advantages.



The stone imitation effect of real stone paint is realistic, and the degree of stone imitation can reach more than 90%.

Therefore, the external wall coating must have the elastic anti cracking function (resin); (4) According to the project modeling and construction technology, it can be divided into flat coating, small drawing, large drawing or relief modeling, but its mechanism must be monotonous than texture coating.

It is waterproof and has good air permeability.

Commonly used brands at present, the main brands in the market include garberry, sankeshu, Nippon, Dulux, STO, China Resources, SKK, meitushi, etc.

Difference between texture coating and real stone paint (1) different visual feelings.

2、 Exterior wall emulsion paint and elastic coating 1.

Industry development trend exterior wall coatings are basically divided into ordinary non elastic latex paint, elastic paint (flat coating, roughening and relief), texture paint, real stone paint, colorful paint, waterborne / oily fluorocarbon metal paint (less used at present), and some special processes, such as the effect of fair faced concrete, For example, the finished products are made of imitation sandstone, imitation limestone and pottery colored stone.

The color of natural colored sand has been determined from the moment of mining; The color of textured sand can be prepared according to artificial synthesis.

Suitable for exterior wall decoration of high-grade and high-rise buildings..

Construction technology 5.

The color and modeling of real stone paint are mainly realized by adjusting the sand or rock chips with different colors and particle sizes in the formula.

5、 Multicolor coating multicolor coating, also known as liquid granite paint, is a water-based coating for building exterior walls, which is composed of two or more water-based coloring particles suspended in the water-based interlayer and produces multiple colors through one-time spraying.

The content of genuine stone paint per square meter is higher than that of textured paint, and the price of genuine stone paint per square meter is slightly higher than that of textured paint; (3) Different construction processes, most of the real stone paints are mainly sprayed, and the texture coatings are mainly scraped in batches; (4) Different materials, the aggregate of real stone paint is natural color sand, and the main material of texture coating is texture sand.

  In 2012, real stone paint rose suddenly and will run up the paint market with new coatings such as colorful coatings and texture simulation coatings in 2013.

Texture coating is natural and environment-friendly, non-toxic and tasteless.

The most mentioned with texture coating is the artistic effect.


It is generally used in commercial outlets, local modeling, high-rise main walls in medium and high-grade parks and foreign houses in medium and high-grade parks.

The price of genuine stone paint is about 55 ~ 75 yuan / m2, which is mostly used for residential and commercial podium.

It is generally used for high-end residential buildings.

The price range is between 65-80.


Sand in water can be said to be an upgraded product of water in water and real stone paint.

Common additives include thickener, antifreeze, preservative and film-forming additives.

After coating a certain thickness, it has the function of covering the small cracks caused by the expansion movement of the substrate; (2) The price of double package in the general market is more than 30 yuan / m2, and the main difference lies in the different quality of the resin used; (3) It is applicable to the area with external wall insulation.

Common effects of colorful coatings: horizontal coating in water effect: special wall tile in water effect: sand in water effect 6.

Advantages of real stone paint.


The decorative effect is similar to marble, granite, white marble and hemp stone, especially for the decoration of indoor columns and roman columns, which can obtain the decorative effect of confusing the false with the true.

There are no special requirements and no color paste is added for color matching.

Elastic coating (1) elastic architectural coating is a kind of architectural coating which takes synthetic resin as the base material and is prepared with pigment, filler and additives.


Living in a house decorated with real stone paint can give people a return to nature, magnificent atmosphere and majestic vitality.

It is a good decoration coating.

A good emulsion paint can still be as new after a few years, without elasticity and anti micro cracking.

Because the external insulation is plate splicing, it will dislocation with the settlement of the building, resulting in the dislocation tension of the external wall coating and the cracking of the coating.

The surface of texture texture is formed by sand particles with different mesh numbers.
