What floor tiles can protect against sun?

First of all, the humidity in the air is obviously not enough in hot weather, which requires us to keep the air humidity moderate and not too dry at the construction site. For example, when plastering wall tiles, our construction master needs to sprinkle water on the wall to make the humidity of the wall reach a certain proportion.

This is a small detail before construction, but it is related to the quality or technology of laying tiles in such weather.
