Polyurethane Concrete (PU Concrete) Flooring

Polyurethane concrete (PU concrete) is a hybrid flooring system that combines polyurethane resin with cement and aggregate. It resists impact, abrasion, chemicals, thermal shock and hot-water or steam cleaning, which makes it the standard choice for food, beverage, pharmaceutical and chemical plants. Demmerg manufactures the DEMCO PUR 303 CONCRETE range of polyurethane concrete flooring.

DEMCO polyurethane concrete systems

DEMCO PUR 303 CONCRETE SL 20 UB/WB: heavy-duty self-leveling PU concrete applied at 6 mm or more. Compressive strength 75 MPa, slip resistance R 11 (EN 16165); resistant to thermal shock, intermittent live steam and hot-water cleaning, and freeze-thaw cycles. Coverage is about 2.1 kg/m² per mm.
DEMCO PUR 303 CONCRETE/W: water-based, slip-resistant PU concrete applied at 3–5 mm with adjustable surface texture. Compressive strength 50.8 MPa; coverage 6.0 kg/m² at 3 mm and about 9.2 kg/m² at 5 mm.
DEMCO PUR 303 CONCRETE SL 23 UT/WB: matt, scratch-resistant polyurethane-cement hybrid topcoat; slip resistance R10 (EN 16165).
DEMCO PUR 303 CONCRETE SL31 COVING/WB: coving and levelling mortar applied at 3–9 mm, 1.8–2.0 kg/m² per mm.
DEMCO PUR 303 CONCRETE NANO ESD/WB: 4–5 mm antistatic PU concrete for areas where static electricity must be controlled; see conductive coatings.

The products are water-based and tested to EN 1504-2 within the scope of the CE certificate.

Where is it used?

Meat, poultry and fish processing; dairy, bakery and confectionery production; beverage plants; pharmaceutical and chemical industries; laboratories; cold stores; wet and dry production and packaging areas. See the guides on food facility flooring and cold store flooring.

PU concrete or epoxy?

Rigid epoxy does not tolerate sudden temperature changes well, while PU concrete is formulated to withstand thermal shock and hot-water or steam cleaning. Choose epoxy flooring for areas at normal temperature and PU concrete for production areas that are washed with hot water or cycle between hot and cold. See Epoxy or polyurethane? or request a quote.
