Sikafloor Quartzite HDB System is a decorative, 5 mm (3/16 in) thick, two layer epoxy floor system. The first layer consists of a 3 mm (1/8 in) thick, trowel-applied heavy-duty epoxy underlayment used to re-profile rough or deteriorated concrete surfaces or to create thin-set slope changes in wet areas in order to provide positive slopes to drains. The second layer is a 2 mm (1/12 in) thick, broadcast and sealed epoxy floor, composed of multi-coloured quartz aggregates finished with transparent top coats to produce a seamless and aesthetic finish. Final surface appearance options include: integral cove base, gloss, satin or matte surface sheen and variable surface texture to produce a range of slip-resistant finishes.
