Not suitable for all occasions
Although the shell powder coating has good breathing and humidity control performance, it can suck the excess water in the room into its own micropores, release the stored water when it is dried indoors, and keep the indoor humidity at all times. However, shell powder paint is not suitable for painting in places with a lot of oil smoke and water, such as bathrooms and kitchens. It is more suitable to use products such as tiles in these places.
The initial investment cost is high.
The price of painting is high, which can reach 300 yuan per square meter, and the initial investment cost is high. Shell powder feels rough, uneven and textured, and does not have the lubricity and delicacy of paint, so shell powder paint has no advantage.
High construction requirements
Shell powder paint is different from latex paint or wallpaper, which requires high construction requirements. It needs a professional and systematic training and construction master with practical painting experience to create a personalized and beautiful shell powder coating wall.
High demand for room temperature
Shell powder construction requires high room temperature, and the indoor temperature is higher than 17 degrees Celsius. In northern spring and autumn, if the indoor temperature can't reach 17 degrees Celsius, indoor heating measures must be taken to ensure the wall color after shell powder construction. Stay together.
Good environmental protection performance
Good shell powder does not contain formaldehyde, but it has the function of adsorbing formaldehyde. The main raw material of shell powder is pure shells, the main component is about 95% calcium carbonate, and a small amount of amino acids and polysaccharides. Soft texture, porous fibrous double helix structure, can absorb harmful gases such as formaldehyde into the holes. In addition, formaldehyde decomposes with CaCO3 and Ca(OH)2 in shell powder to obtain carbon dioxide and water, thus completely degrading formaldehyde and purifying indoor air.
