Harmful carcinogen such as decomposing formaldehyde, benzene, radon gas.
But the durability against pollution of diatom ooze still has certain gap compared with the professional emulsion paint in part and ceramic tile.One
As, the good emulsion paint of resistant effect can accomplish that common spot can not be impregnated with, and can be cleaned out in surface wipes with wet rag,
Ceramic tile surface has a glaze paint protection, this respect it is with better function, and diatom ooze is because the presence of surface porosity, if commonly
Dust or soil are also easier to clear up, but run into the strong spot of some permeability, especially fluid, it is likely that can be because oozing
Left through depth irreversible " scar ".
