Where to apply AC1 mortar? And why?
It should only be applied indoors, as long as there is no heavy traffic of loads and machines. Never outdoors because it cannot withstand temperature variations.

It is necessary to check that all the coating to be applied is free from dirt (dust, grease, fat, oil, etc.) and that it is well adhered.
How do you know if the mortar that has been opened with a cloth is still in adhesive condition?
If we touch it with our fingertips and they get dirty with adhesive mortar, it will make the ceramic coating adhere, but if the fingertips do not get dirty, it will not be possible for the ceramic coating to adhere.
How many hours after laying the coverings should grouting be done and why?
Grouting must be done 72 hours after laying the coverings, because the adhesive mortars take 72 hours or 3 days to completely cure.
If I grout before 72 hours have passed since laying the coverings, what can happen?
The grout will certainly be contaminated with the water contained in the adhesive mortar, and after it has cured it will present a stain (variation in tone).

What is it called? And what to do with the white powder on the back of the coatings?
It is called Engobe, and it must be removed, as it will make it difficult for the mortar to adhere to the coating and vice versa.
