abe.®flo HPU is a four component polyurethane self-smoothing topping, applied between 2 and 6 mm, in general 4 mm thick, available in a range of matt colours.
abe.®flo HPU provides a heavy duty, thermally shock resistant, hard wearing floor finish with exceptional chemical resistance.
Typical areas of application include food processing factories, chemical processing plants, and pharmaceutical production for use in wet and dry process areas where the floor is subjected to hot fluid spillage steam cleaning, heavy traffic, impact and chemical attack.
- Impact resistant.
- Seamless and hygienic finish, no crevices where dirt and bacteria can collect.
- Excellent chemical resistance.
- Easy to clean and sterilise, low maintenance requirement.
- Matt finish.
- High abrasion resistance.
- Low odour during installation.
abe.®flo HPU is not colour stable and may discolour on ageing; this is more noticeable in light colours. This will not impair its chemical resistance. Where colour matching is required over more than one order or delivery, a.b.e.®’s Technical Department must be contacted prior to placing the order(s) and the requirement stated clearly on all orders relating to the project(s).
The colour range includes dark green, mid grey, mustard, cream, blue and red.
Variations in aggregates can cause variations in floor colour. Although every effort is made to keep product colours consistent, it is advisable to use product from the same batch in specific areas. Products can be pre-blended to further limit colour variations.
Substrate must be concrete or polymer modified screed above 25 MPa compressive strength and a minimum of pull off strength of 1.5 MPa.
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.

Do not apply the coating if the substrate temperature is at least
3 ºC (5 ºC is better) above dew point.
All movement joints need to be carried through the abe.®flo HPU 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 abe.®flo HPU will reflect the cracked areas subject to large temperature changes, the effect of these changes on the substrate movement must be considered.
Bonding / Priming
PU/HPU primer is recommended as a pore sealer and must be allowed to cure. Priming must be undertaken in the late afternoon (i.e. declining substrate temperature).
Use the relevant abe.®screed PU CG coving grade colour with appropriate primer for coving and/or vertical applications.
Kit components are pre-weighed for optimum performance.
Never split or proportion kits. The prescribed aggregate must be used as supplied in kit form and not substituted with an alternative. A forced action pan mixer is recommended. Do not mix by hand.
Mechanical mixing using a heavy duty drill and helical mixer may be considered. The heavy duty drill/stirrer should provide a minimum of 1100 W input power, 600 W output power, torque 45 Nm and variable speed of 0 to 700 rpm, including a heavy duty paddle having a 120 mm diameter and helical stirrer height of 100 mm suitable for mixing cement mortars and grouts (see typical illustration of a helix stirrer on last page). The rotation of the stirrer should be such that the material is lifted from the bottom of the mixing container upward during mixing. The mixer is to be used at slow speed to avoid air entrapment. To the clean mixing vessel add the base component followed by the liquid pigment and mix for 30 seconds, add the hardener component and mix for approximately 30 seconds until the colour is uniform. Finally whilst mixing slowly add the aggregate component to avoid lumps forming and mix for at least 3 minutes, until the mixture is homogenous and uniform.

Within one minute after mixing, spread the topping onto the primed floor to the required thickness using a steel-bladed trowel, or pin rake set to the correct depth. Within 3 minutes of application, roll with a spiked roller. Lay abutting mixes within 3 minutes of application of previous mix. Maximum bay width is 5 metres.

Protection on Completion
Protect surface against traffic and spillage until cured.
The floor topping will be abe.®flo HPU, a four component polyurethane self-smoothing floor topping applied in accordance with a.b.e.® Construction Chemicals’ recommendations.
abe.®flo HPU is supplied in 30 kg packs, consisting of base, hardener, aggregate and pigment.
Handling & Storage
All abe.®flo HPU related products have a shelf life of 12 months if kept in a dry, cool store in the original, unopened packs. If stored at high temperatures and/or high humidity conditions, the shelf life may be reduced.
Health & Safety
When wet, abe.®flo HPU is toxic and flammable. Ensure working area is well ventilated during application and drying. Avoid flames in vicinity. Avoid inhalation of dust and contact with skin and eyes. Suitable protective clothing, gloves, eye protection and respiratory protective equipment should be worn. The use of barrier creams provides additional skin protection. If contact with skin occurs, wash with water and soap. Splashes into eyes should be washed immediately with plenty of clean water and medical advice sought.
When cured, abe.®flo HPU is inert and harmless.
NB: When transporting liquids and semi-liquids by aircraft, ask for material safety data sheet.
