01 Industry development trends and brands commonly used in the market
Exterior wall coatings are basically divided into ordinary non-elastic latex paints, elastic coatings (flat coating, brushed, embossed), textured coatings, real stone paints, colorful coatings, water-based/oily fluorocarbon metallic paints (currently used less), and some Special processes, such as fair-faced concrete effects, such as finished imitation sandstone effects, imitation limestone, pottery stone
In recent years, real stone paint has sprung up, and it has started the paint market with new paints such as colorful paints and texture simulation paints
02 Exterior wall latex paint and elastic coating
Ordinary non-elastic exterior wall latex paint
It only has the effect of cleaning and beautifying.
A good latex paint can still be as new after a few years, has no elasticity, and has no effect of preventing micro-cracking, so it is not suitable for use in North China, Northwest China and other regions;
It can only be used in East China, South China and other areas without external wall insulation .
More commonly used for building renovations, fences, and inside balconies
The elastic architectural coating is based on synthetic resin, and is formulated with pigments, fillers and additives.
After applying a certain thickness, it has the function of covering the fine cracks generated by the expansion and contraction of the substrate;
It is suitable for areas with external wall insulation.
Because the external insulation is plate splicing, dislocation will occur with the settlement of the building, which will cause the dislocation and tension of the external wall coating coating, which will cause the coating to crack.
Therefore, the external wall coating must be elastic.
Anti-cracking function (resin);
According to the project modeling situation and construction technology, it can be divided into flat coating, small pull flower, large pull flower or relief modeling, but its mechanism must be more monotonous than texture paint
It is generally used in the main walls of high-rise buildings in low-end parks and other ancillary buildings
03 Texture paint
Texture paint generally refers to the use of specific tools to paint with obvious personalized texture effect, which is different from ordinary flat-painted interior and exterior wall paint
The textured surface is formed of sand grains of different mesh sizes
The general shape is simple
It is generally used in commercial outlets, local modeling, high-rise main walls in mid-to-high-end parks and houses in mid-range parks

04 Industry development trends and commonly used brands in the market
Real stone paint, also known as natural real stone paint, stone paint and imitation stone paint, is a high-build architectural paint composed of synthetic emulsion as base material, natural colored sand powder particles as aggregate, and a small amount of additives.
The decorative effect is similar to marble.
, granite, white marble, granite, especially for indoor columns, Roman columns and other decorations, can obtain a false and real decorative effect
The color and shape of real stone paint are mainly realized by adjusting the different colors and different particle sizes (sizes) of sand or rock chips in the formula.
There is no special requirement to add color paste
Real stone paint is mostly used in residential and commercial buildings
The main components of real stone paint
Emulsion + colored sand + various additives = real stone paint
Characteristics of natural colored sand
Granite and powder products processed by various granite or marble natural ores through selection, crushing, crushing, grading, sand mixing, packaging and other processes;
Excellent color retention performance, no fading;
The intensity, color and particle size are difficult to control, and change with the change of ore;
The resources are in short supply and the supply is in short supply.
The varieties that can be supplied stably have been reduced from forty or fifty kinds five years ago to ten kinds now
Commonly used additives include: thickeners, antifreezes, preservatives, coalescents
The production process of real stone paint
The production process of real stone paint is divided into two steps:
Preparation of real stone paint slurry
The real stone paint slurry is mixed with colored sand to make real stone paint
Construction technology of real stone paint
Advantages of real stone paint
Real stone paint has the advantages of good decoration, wide application, easy construction, water-based environmental protection, and good weather resistance
Common effects of real stone paint
●Imitation brick effect (spraying)
● Texture effect (spray)
The difference between texture paint and real stone paint
(1) Different visual experience
The imitation effect of real stone paint is realistic, and the degree of imitation of stone can reach more than 90%.
Living in a house decorated with real stone paint can give people a return to nature, a magnificent atmosphere, and a solemn and majestic vitality
The most mentioned thing with texture paint is the artistic effect.
Through the outline of artistic beauty, the designer makes abstract thinking vivid on the wall, which can produce a unique visual experience;
(2) Price difference
The content per square meter of real stone paint is higher than that of textured paint, and the price of real stone paint per square meter is slightly higher than that of textured paint;
(3) Different construction techniques
Most of the real stone paint is mainly sprayed, and the textured paint is mainly scraped;
(4) Different materials
The aggregate of real stone paint is natural colored sand, and the main material of textured paint is textured sand
The color of natural colored sand has been determined from the moment of mining; the color of textured sand can be adjusted according to artificial synthesis
The texture coating is natural and environmentally friendly, non-toxic and tasteless, both waterproof and breathable.
It is a good decoration coating
05 Industry development trends and brands commonly used in the market
Colorful paint, also known as liquid granite paint, is a water-based paint used for building exterior walls, which is composed of two or more water-based colored particles suspended in a water-based medium layer, and produces multiple colors through one spray
Water-in-water and sand-in-water are collectively referred to as colorful coatings
