Medium duty 2,5 – 4mm self smoothing polyurethane floor screed

abeflo HPU is a medium duty flow applied polyurethane topping based on a 4 part, liquid polyurethane resin system incorporating antimicrobial silver ion protection. A textured, smooth aggregate surface of uniform colour designed for excellent resistance to abrasion, chemical attack and other physical aggression for light to medium traffic.

  • Contains silver ion technology for antimicrobial protection
  • Easy to clean and sanitize due to seamless flooring
  • Heat resistant to 80 °C
  • High chemical, abrasion and impact resistance
  • Non-slip matt finish
  • Solvent free application
  • Low VOC content
  • Fast installation easy to use fluid consistency with excellent adhesion
  • Chemical processing plants
  • Food processing plants with antimicrobial additive based on silver ion technology making abeflo HPU ideal for use in HACCP environments as it provides a seamless, antimicrobial, matt finish that imparts no chemical contaminants to foods
  • Breweries
  • Engineering areas

Substrate Requirements
Concrete substrates are to be 20-25 MPa compressive strength and 1.5 MPa tensile adhesion strength, free of dust and friable materials. There must be no moisture vapour rising from the concrete and moisture content must be less than 5%.

Totally enclosed heavy shot blasting or scarification should be used to remove all residues to provide a dry, dust free open textured surface with exposed aggregate. Anchor grooves, minimum 4 mm wide x 4 mm deep, must be formed at all edges, bay joints, columns doorways, drains and at regular centres across the floor. Generally, groove width and depth is twice the screed thickness. If time constraints (or any other) results in application of screed short of these anchor groves, then cut new groves to finish off application and start next application with new groves.

1. Concrete Primer – PU/HPU primer + Silica sand No.2 fine
2. Polyurethane topping – abeflo HPU


Prepare surfaces in order to obtain a sound, dust free, dry surface. Prime with PU/HPU primer + scattered aggregate and allow to cure for at least 24 hours prior to application of abeflo HPU with a maximum overcoating time of 48 hours. Ensure application conditions are between 10 – 25 °C and at a maximum of 75% relative humidity.

Before mixing, turn the resin bottle upside down and shake vigorously to re-suspend any sedimentation. Mix the shaken resin and hardener in a pan mixer well. Then add the aggregate and, after the last of the aggregate has been added, mix until uniformly wetted out. Pour out the mix onto the demarcated area and trowel out into place. Spike roll out trowel marks and allow to settle.


Use the relevant abescreed PU CG coving grade colour with appropriate primer for coving and/or vertical applications.


Regular scrubbing and mopping will maintain the abeflo HPU in a serviceable condition.

Antimicrobial Resistance
The abeflo HPU makes use of silver ion technology in formulation which inhibits the growth of bacteria and fungi in contact with the product. The hygienic advantage is therefore not only derived from the daily use of the floor but in the longer life this technology affords in retarding the degradation of the floor by micro-organisms.

Colour Stability
abeflo HPU is not colour fast and will change in colour over time, especially when subject to direct sunlight and high intensity lighting. The rate of colour change is unpredictable.


Stain resistance is enhanced if the abeflo HPU surface is sealed.


Store the kit in a cool, dry place out of direct sunlight and where there is no exposure to damp and humidity.
