abe.®screed PU is a heavy duty trowel 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.

Uses
  • Chemical processing plants
  • Food processing plants with antimicrobial additive based on silver ion technology making abe.®screed PU ideal for use in HACCP environments as it provides a seamless, antimicrobial, matt finish that imparts no chemical contaminants to foods
  • Breweries
  • Engineering areas
Advantages

Directions

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 are twice the screed thickness. If time constraints (or any other) result in the application of screed short of these anchor groves, cut new groves to finish off the application and start the next application with new groves.

System

  1. Concrete Primer – PU HPU primer +Silica sand scatter 1.8 mm
  2. Polyurethane topping – abe.®screed PU
Application

NOTE: New cured concrete should alwyas be primed to avoid outgassing. 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 abe.®screed PU with a maximum over coating time of 48 hours. Ensure application condition 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 resuspend
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.

Coving

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

Maintenance

Cleaning
Regular scrubbing and mopping will maintain the abe.®screed PU in a serviceable condition.

Antimicrobial Resistance
The abe.®screed PU makes use of silver ion technology in the 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
abe.®screed PU 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.

Sealing

Stain resistance is enhanced if the abe.®screed PU surface is sealed.

Storage

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