1.Scope of application:
It is suitable for decoration of interior walls, exterior walls and tunnel openings in various luxury and high-grade places, roman columns, special-shaped beams, columns and lines of molding materials. It can be painted arbitrarily with the shape of buildings.
2.Performance characteristics:
(1)Ultra high simulation degree: the surface of the surface is smooth and concave, the colors penetrate each other, and the color particles bloom naturally in the spraying process, creating the aesthetic feeling like natural granite.
(2)Good batch stability: the color is controlled by the color paste, which is easy to control the batch color difference, and is convenient for later renovation and repair.
(3)Convenient construction and short construction period: molding layer and pattern layer are formed by one shot, which is very convenient and the construction period is short.
(4)Suitable for a variety of base surfaces: not affected by the base surface modeling, suitable for a variety of base surfaces. It can be painted with the shape of the building to maximize the architect's architectural inspiration.
(5)Safe and at ease: compared with natural granite and real stone paint, it can greatly reduce the wall load. It can solve the problem of overweight dry hanging load, serious corrosion and aging, life and property.
(6)Good crack resistance: good ductility, which can cover small cracks on the wall.
Water based environmental protection: the unique water-based technology makes it completely water-based, replacing the increasingly rare natural granite stone, reducing the demand for natural colored sand of stone paint, and having more environmental protection advantages and sustainability.
(7)First choice for high-end buildings: high resin content, excellent weather resistance, alkali resistance, flexibility, self-cleaning and UV resistance, and not easy to fade, so it is the best choice for high-end building decoration.
(8)Excellent weather resistance: wash resistance, acid and alkali resistance, waterproof, mildew proof, high bonding strength, good self-cleaning, service life more than 30 years.
High cost performance: the cost is only about 15-25% of that of natural granite.
Wide range of uses: it is suitable for decoration of interior walls, exterior walls and tunnel openings in various luxury and high-grade places, as well as roman columns, special-shaped beam columns and lines of molding materials. It can be painted arbitrarily with the building shape.
3.construction technology:
(1) base surface treatment
Before the base treatment, the wall needs a certain period of maintenance. Generally, the curing time of new cement wall in winter is 28 days, and that in summer is 14 days. After curing to the pH value of the base course is less than 10 and the moisture content is less than 10%, the base surface shall be treated. The contents of base surface treatment include: removing the loose matters on the base surface; reducing or eliminating the surface defects; improving the physical or chemical properties of the base surface.
(2) apply low temperature flexible putty
Repair the wall with low-temperature flexible putty. Level the first layer locally, fill the large holes and gaps with putty. After the putty is dry, grind it locally, and then apply the putty to make the base level.
(3) roller coating or spraying special primer (black)
After the putty meets the requirements, the putty shall be polished and leveled, the floating dust shall be cleaned, and the special primer (black) shall be evenly applied or sprayed. Be careful not to miss or over coat.
(4) Division
According to the design requirements or the shape of the building, the partition area is generally rectangular, 80 * 120cm, 60 * 90cm, etc., and the line is generally less than or equal to 1cm wide.
(5) middle layer
Roller coating or spray Painting with the same color for one to two times.
(6) spraying water in sand colorful coating
Mix the sand in water multicolor coating evenly and then put it into a special spray gun with 4.0 or 5.0 caliber. During spraying, the working pressure and discharge volume of the spray gun should be adjusted according to different requirements of concave convex degree and particle size (the pressure should be controlled within 0.1-0.2mpa). The distance between the spray gun and the wall should be about 30-40cm. During spraying, the spray gun should be vertical to the wall, the gun should be stable, the speed should be uniform, and the gun should be stopped as little as possible. The partition line of the wall shall be taken as the standard, and the block spraying of joint and grid is preferred.
(7) tear textured paper
Remove the textured paper before the multicolor coating of the sand in water dries.
(8) roller coating or spraying water-based matt finish paint
After the water-borne sand multicolor coating is dried, roll or spray water-borne matt finish paint evenly.
4.matters needing attention:
(1) for products stored in static state for a long time, it can be stirred slightly before opening the cover, and forced stirring is not allowed.
(2)In order to ensure the integrity of the coating, please use matching products.(
(3)Pay attention to the influence of climate on the coating construction. Construction in rainy and snowy days and high temperature climate should be avoided. The construction interval of each coating layer should be determined according to different climate. When the temperature is below 5 ℃ and the humidity is above 80%, the construction shall not be carried out.
(4) if the nozzle is sprayed up and down during spraying, use the nozzle horizontally; if the nozzle is left and right spray, and the nozzle is used vertically, the coating effect will be better.
(5)Pay attention to the uniformity of spraying when the distance between scaffold and wall is too close to avoid foot mark.
(6)The brushing tools should be cleaned and kept properly after use every day. In case of stopping the gun during spraying, the spray gun can be soaked in clean water temporarily to avoid blocking the gun due to dry and solid materials.
Please use face mask, gloves and other protective equipment when using. If eyes are stained or uncomfortable, please clean them with water and seek medical advice in time.
