Is it waterproof, what does water absorption actually do, and why the binder decides it.
7 questions in this harvest fall under this subject. 2 answered so far.
For cement-bound terrazzo it is commonly between 0.3% and 0.6%. For resin-bound terrazzo it is effectively nil, because the binder is the resin rather than a cement matrix. That difference decides whether a material can go in a wet room, which is why the binder is named in every figure this site publishes.
It depends which grade you are buying, because the Chinese standard grades it: 8.0% or less for standard terrazzo, 6.0% for high-performance, 4.0% for cement artificial stone, and 1.0% for the high-performance version of that. Absorption is the figure that decides whether you seal, and how often.
These are the phrasings people typed, not headings we invented. Where one has an answer the link is live; where it does not it is printed plain, and that is deliberate — a printed question with nothing behind it is an honest promise, and hiding it is not.
