High cost
High-quality diatom mud needs to be added with decomposition materials and constructed by professionally trained diatom mud wall artists, so it is more expensive than ordinary latex paint.
High construction requirements
In order to achieve the perfect construction effect, diatom mud must be constructed by professionals, so as to ensure the beauty and the construction quality of the wall, and it is impossible to paint it yourself.
Uneven quality
Photocatalyst (nano-TiO _ 2/diatomite composite photocatalytic material) needs to be added to diatom mud to decompose the adsorbed harmful gases and really protect the environment. However, at present, the diatom mud market is mixed, and not all brands have patent decomposition technology, so please choose a big brand with good reputation and strong strength when purchasing.
Not suitable for painting in bathroom and kitchen.
Diatom mud has a strong adsorption, which is an advantage to some extent, but because of this, in the bathroom. These areas with water in the kitchen are not suitable for painting.
It's hard to tell good from bad.
Diatomite plays a role in diatom mud. But diatomite can't be identified by naked eyes, so it is difficult to judge its quality only by naked eyes.
