Ultratop [NA] is a self-curing topping that is specially formulated for fast-track resurfacing, allowing Ultratop [NA] to be polished 24 hours after being installed. Also, the polishing process of Ultratop Terrazzo System is a “dry” process, so you do not need to manage the dirty water.
There can be different explanations of why this happened. The grout may have been washed too soon or too much during the cleaning process, causing pigment to be removed from the grout. Or, the grout powder may not have been dry-blended before mixing in order to avoid color variation.
Ultratop Terrazzo System can be less expensive than terrazzo that is made with epoxy resin, based on the product cost. Designers can also increase the amount and the size of aggregates with less of an increase in price because cementitious products will always be less expensive than epoxy products.
