Six months when kept in a cool, dry place. Packaging must remain unopened.

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%.

System Product Requirements
1. Concrete Primer – PU HPU primer + Silica sand No.1 course
2. Screed Topping – abescreed PU CG

Application
Prepare surfaces in order to obtain a sound, dust free, dry surface. Prime with PU / HPU Primer and allow to cure for at least 16 hours prior to application of abescreed PU CG with a maximum over coating 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.

For rendering applications anchor grooves, a minimum 8 mm wide x 8 mm deep, must be formed at all perimeter edges.

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 grooves, then cut new grooves to finish off application
and start next application with new grooves.

All vertical surfaces must be of a rigid construction to resist deflection during the application process.

All movement joints need to be carried through the abescreed PU CG and properly sealed. Subject to environmental conditions consult your local a.b.e.^® representative for the appropriate sealant type.

Construction joints and cracks may be covered but if substrate movement occurs, the abescreed PU CG will reflect the cracked areas subject to large temperature changes. The effect of these changes on the substrate movement must be considered.

Antimicrobial Resistance

The abescreed PU CG 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 microorganisms.

Colour Stability
abescreed PU CG 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.

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 abescreed PU CG 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.
