Self-Leveling Urethane UltraCrete™ 3KPU

Fortis UltraCrete™ 3KPU is our urethane-based system is a heavy-duty seamless resurfacer that provides exceptional durability and service.


UltraCrete™ 3KPU is our 2 or 3 component trowel-applied cementitious polyurethane that is applied in thicknesses ranging from a 5mm to 20mm. Ideal for resurfacing of food processing areas, commercial kitchens or eroded factory floors. UltraCrete™ 3KPU is chemical resistant and able to withstand thermal shock from spills, high-temperature washdown. It gets you back up and running quickly and meet the demands of your operation.

Construction, Concrete, Industrial & Mining


Application of UltraCrete™ 3KPU polyurethane flooring should take place after priming but within 24 hours.


Mix Components A (resin) and B (hardener) in the predetermined mixing proportions provided. Stir the for approximately 3 minutes with a low-revolution (300 rpm) mixer. To achieve uniform dispersion of the hardener make sure the stirring reaches the wall and bottom of the container. Then, add the 3rd Component to obtain a uniform polyurethane mortar.

For a Smooth Final Surface

Spread UltraCrete™ 3KPU  with a notched trowel at a thickness up to 30mm. To remove any air trapped in the self-levelling layer, go over the surface with a special spiked roller. This inhibits the formation of bubbles.

For a slip-resistant Final Surface

Whilst the coating is still fresh, sprinkle it with quartz sand, grade 0,1-0,4 mm or 0,4-0,8 mm (depending on the desired slip resistance), at a rate of 3 kg/m2. Remove excess loose sand once UltraCrete™ 3KPU has hardened. Seal with a coat of FORTIS COAT 527 or UltraSpart in the desired colour.


The surface on which the UltraCrete™ 3KPU coating is going to be applied must be dry (<4% moisture), stable, free of dust, loose particles, grease.  The substrate must be properly prepared. Refer to Technical Note #4 - Surface Preparation, to open the pores to allow penetration of the primer and ensure better anchoring and bonding of the polyurethane coating. Subsequently, the surface should be carefully cleaned with a high suction vacuum cleaner. The properly prepared surface (as described above) is then primed with HydroFort™ Primer.
