The redispersible polymer powder contained in the artistic surface mortar can ensure the strong bonding between the surface material and the concrete base material, and gives the artistic mortar good bending strength and flexibility, allowing it to better withstand dynamic movements. load without being damaged, and the mortar surface layer can better absorb the internal stress generated by changes in environmental temperature and humidity inside the material and at the interface, avoiding cracking, peeling, etc. of the surface mortar; Dispersed latex powder can also significantly reduce the water absorption of the surface mortar, thereby reducing the intrusion of harmful salts, reducing the decorative effect of the surface mortar and damaging the durability of the mortar.
Using the embossing process, you can get a surface with the same decorative effect as the traditional embossed concrete process. First, use a scraper or trowel to apply the interface layer of the polymer-modified cement material as thinly as possible, with a thickness equal to the maximum particle size of the sand. When the putty layer is still wet, use a nail rake with a gauge to spread about 10mm thick colored art mortar, use a trowel to eliminate the rake marks, and then use the same stamp as for traditional stamped concrete to stamp out the pattern texture. After the surface layer is dry, spray a pigmented sealer. The sealant liquid will bring the color to the low areas to create a rustic style. Once the raised area is dry enough to walk on, apply two coats of acrylic clear cover sealer over it. It is recommended to use anti-slip cover sealant for outdoor use. After the first sealant is dry, apply the anti-slip coating. Usually, the surface layer can be stepped on after 24 hours of curing, and can be opened to traffic after 72 hours.
At this stage, self-leveling art mortar surfaces are mainly used indoors, usually with patterns formed by dyeing. They are often used in commercial places such as car exhibitions, hotel lobbies, shopping malls, and theme parks. They are also suitable for floor heating floors in office buildings and residential buildings. . The designed thickness of the polymer-modified self-leveling art mortar surface layer is about 10mm. Just like the construction of self-leveling floor mortar, first apply at least two layers of styrene-acrylic emulsion interface agent to close the pores on the concrete substrate and reduce its water absorption. Increase the adhesion between the self-leveling mortar and the concrete base material, then spread the self-leveling mortar surface layer, and use an exhaust roller to eliminate air bubbles. When the self-leveling mortar hardens to a certain extent, you can use relevant tools to carve or cut patterns on it according to your design and imagination. In this way, you will obtain a decorative effect that cannot be obtained by using other decorative materials such as carpets and ceramic tiles. More economical. Patterns, artistic designs and even company logos can be made on the self-leveling surface. Sometimes it can even be combined with the cracking of the base concrete or the parts that cause the cracking of the surface to be artistically hidden. Color can be obtained by adding pigments to dry-mixed self-leveling mortar in advance, or more often through post-staining treatment. Specially formulated colorants can chemically react with the lime components in the mortar. These substances slightly etch and will The color is fixed in the finish. Finally apply the cover sealant.
The average cost of concrete art mortar surface is usually 1/3-1/2 more than the cost of natural stone materials such as slate or granite. Hard flooring materials such as tile, granite or decorative concrete may not appeal to consumers who prefer softer materials such as carpet or soft vinyl. Disadvantages may be the sensation of heat underfoot, the scattering of sound and the possibility of shattering from falling objects, or the safety of the ground where a child may crawl or fall. Many people would like to lay down area rugs on hard floors or long carpets in walkways and areas to add beauty, but these options need to be included in the budget. As one of the effective means to beautify concrete, artistic surface mortar is simple, economical, durable and easy to maintain compared to traditional decorative cladding materials. It is the best embodiment of people's aesthetics and creativity.
