Application of re-dispersible latex powder in concrete artistic mortar
The development of concrete surface art

Concrete, as an economical, easy to formulate and process building material with excellent physical and mechanical properties, durability, practicality and reliability, is widely used in civil engineering construction. However, it is inescapable that if only cement, sand, gravel and water are mixed, what is obtained at this time is ordinary concrete, the appearance of which is less pleasing to the eye in tone, and easy to gray and return to the salt frost. Therefore, indoor concrete floors are usually covered with carpet, vinyl or tile and other coverings, while walls are mostly painted, tiled or finished with mortar and wallpaper as a decorative layer.
Today, the decorative concrete art mortar surface process has become one of the highly respected means of artistic concrete surfaces in North America and Australia. This originated in the 1950s concrete surface embossing pattern process (stampedconcrete), that is, in the fresh concrete surface sowing color hardener, through the use of pattern molds and release agent, in the concrete surface molded to simulate the natural form of the texture pattern, such as granite, marble, slate, cobblestone, or the texture of the texture of the wood weave, to meet the needs of people on the decorative effect of natural materials. This technique is not only suitable for fresh concrete, but also for the surface of the concrete. This technology is not only suitable for fresh concrete, but also for the renovation of existing concrete surfaces, such as home patios, garden paths, driveways, swimming pools, shopping malls and hotel floors. This so-called artistic mortar surface decorative effect has a natural realism and uniqueness, can be the dull appearance of the new concrete, but also decorative, functional in one, not only with the economy, durability and practicality of concrete, but also the combination of aesthetics and creativity organically.
In contrast, the life expectancy of common concrete substrates far exceeds that of commonly used overlays, while carpet and vinyl are susceptible to tearing, staining and abrasion, as well as water staining, and these flooring materials need to be replaced every few years. Artistic mortar coverings, on the other hand, are as durable as concrete and are sanitary, easy to maintain, and their decorative effect can easily be achieved to match the surrounding architectural style and blend into the surrounding scenery. Unlike carpet or vinyl veneers, artisanal mortars are not susceptible to damage from tearing, sticking, abrasion, or water spills; there are no fibers or fissures to hide dust or allergens, and they are easy to sweep or rinse with minimal maintenance. Compared to the process of imprinting a pattern on a new concrete surface, the artistic mortar topping process is simpler, faster and more economical!
Key to the Composition of Artistic Surfacing Mortars

Unlike traditional plasters, concrete art mortars must contain organic polymers in addition to pigments, which are referred to as polymer-modified dry-mix mortars. This polymer-modified cementitious surfacing material is composed of cement, aggregates, pigments and VINJANAPAS dispersible latex powder and other additives, through the adjustment of the formula can well meet the constructability and hardening of the various performance requirements.
Polymer-modified cementitious surfacing materials were introduced into commercial flooring projects in the 1980s, initially used as thin-layer repair materials for concrete surfaces. Today’s artistic surface mortars can be used not only for flooring decoration in a variety of settings, but also for wall decoration. Polymer-modified artistic surface mortar can be coated very thin, its thickness can be the maximum particle size of sand, or thickness of several tens of millimeters without fear of peeling, cracking, and more importantly, polymer-modified cladding has a stronger resistance to salts, aggressive substances, ultraviolet rays, harsh climatic conditions, and wear and tear of the traffic brought about by the ability to damage.
Art surface mortar contains dispersible latex powder, its high adhesion can ensure that the surface material and concrete substrate solid combination, and give the art mortar good bending strength and flexibility, can better withstand dynamic loads without being damaged, and make the mortar surface can better absorb the environmental temperature and humidity changes in the material and the interface at the internal stresses generated to avoid the surface mortar cracking, spalling, etc.; If the use of water-repellent properties, the polymer modified cladding has a stronger resistance to salt, aggressive substances, ultraviolet, harsh climatic conditions and traffic wear and tear brought about by the ability. If the use of dispersible latex powder with water-repellent properties, it can also significantly reduce the water absorption of the surface mortar, thereby reducing the intrusion of harmful salts into the surface mortar decorative effect of the reduction of the durability of the mortar damage.

Artistic surface mortar used on existing concrete surfaces should first be degreased and acid-washed. If there are other surfacing materials on the concrete such as paint, tile mosaics, adhesives, etc., these must be mechanically removed to ensure that the artistic mortar surface can be mechanically/chemically bonded to the concrete substrate. Cracked areas should be pre
