Noted your observations on the flooring of which we had commented on this with Project Management , Dan whom I have in copy, after inspection of the completed floor during the last site meetings in LP.
The supplier explanation is that the product being self levelling and that the aggregate is gradually exposed over the 28 day curing process to achieve the finish performance specification.
I have requested that Pascal bring the approved swatch sample of the finished product specification with him to the site meetings in LP next week at which time we can review this against current finish attained.
