This elastic stone paint has a unique elastic formula, with an elongation at break of more than 300%, which can effectively adapt to the slight deformation of the wall substrate and cover micro-cracks with a width of 0.5mm, solving the common problem of coating cracking caused by wall settlement and temperature changes. It has a good bonding strength, which can firmly adhere to old exterior walls with micro-cracks, and will not peel off after long-term use. It also has good weather resistance, with a service life of 18 years, and meets low VOC environmental protection standards. It can be used for exterior wall decoration and renovation of villas, old residential buildings and other scenarios, providing a perfect solution for solving wall micro-crack problems.
The specific technical parameters are as follows: The base material is natural colored quartz sand + elastic acrylic emulsion, with elongation at break ≥300%, can cover 0.5mm width micro-cracks on the substrate, VOC content ≤40g/L, tensile bond strength ≥0.8MPa, weather resistance life of 18 years, stain resistance grade 4, surface drying time of 2 hours, hard drying time of 22 hours, coverage rate of 30-35 square feet per Gallon, water resistance ≥1100 hours. It is suitable for concrete, brick, old exterior walls with micro-cracks, with packaging specification of 5 Gallons per drum and net weight of about 18kg.
It is mainly suitable for exterior wall decoration of villas, old residential buildings, prefabricated building exterior walls and other walls with minor micro-cracks. It can effectively solve the problem of coating cracking caused by wall settlement, temperature changes and other factors, and restore the beautiful texture of natural stone for the wall. It can be constructed by spray gun or scraping, adapting to most conventional exterior wall construction processes, and can also be used for interior wall decoration of some large-span buildings with slight crack risks.
