Angidrid floor screed what it is

What is the angidride screed of the floor

Angidrid floor screed is made of dehydrated gypsum – anhydride. The anhydrid screed differs in properties from the concrete and cement screed.

It has high resistance to temperature differences, thanks to the liquid structure it easily laid and dries very quickly. The disadvantage of this type of screed is its sensitivity to humidity. Therefore, for wet rooms, if the screed is associated with the base and there is no waterproofing, its use is not recommended.

If the screed is associated with the base of the floor, then it is necessary to perform the primer of the base with a special acrylic primer in order to increase the adhesion of the solution and base, increase the strength of the solution, reduce the likelihood of cracks.
