The white coating that appears on the tiles shortly after they are laid is the very same efflorescence that undoubtedly spoils the appearance of the tiles.
The reason is salts of carbonate and sulfate origin, which form on cement-based surfaces as a result of contact with water.
The formation of salts on paving slabs is inevitable, but their quantity can vary from insignificant to abundant.
Don't try to wash off the efflorescence with water - when the tiles dry, they will become even whiter than they were.
To get rid of the white coating, you will need acid, and there are 3 different ways to go about it.
Vinegar
Mix 9 liters of water and 1 liter of 9% vinegar in a bucket. Mix and apply to the surface with a brush. Leave for 30 minutes, then rinse with water.
Citric acid
Dissolve 25 grams of citric acid in a glass of warm water and apply it to the efflorescence with a brush. After 30 minutes, wash the acid off the surface.
"Coca-Cola"
Pour soda over the efflorescence and leave the tile like this until the drink is washed away by rain.
