Heavy-Duty Metallic-Aggregate Topping.

abe.®top is an industrial floor topping that provides extended working time and extra heavy duty protection against abrasion and impact. 

Whether applied over new concrete or over existing hardened concrete, this topping gives an appreciably longer serviceable life than normal, high strength concrete or natural-aggregate toppings. 

Along with compressive strengths, abe.®top topping has a lower modulus of elasticity than equal strength concrete toppings. Thus, abe.®top is less brittle and more resistant to dynamic loads. Impact resistance and total energy-absorbing capacity – known as toughness – are also improved. 


  • Key areas subject to heavy traffic, impact, abrasion and continuous wear – loading docks, aisles, refuse transfer facilities, truck or tractor repair areas, and mill scale flumes. 
  • Areas where safety inspectors have deemed other floor surfaces hazardous because of excessive wear, dangerously buckled steel plates and other considerations. 


Should not be used in areas where excessive corrosion is likely due to exposure to acids, their salts or other materials which seriously and rapidly attack cement and/or iron. 



  • Highly abrasion resistant – has eight times more wear-resistance than plain concrete. 
  • Greater toughness – energy-absorbing capacity is significantly greater than plain concrete and high-strength, natural-aggregate toppings.
  • Added impact resistance – tests show impact resistance four times greater than plain concrete. 
  • High density – reduces oil and grease penetration, and many industrial chemicals. 
  • Reduced shutdown time – floors can be returned to service faster. 
  • Low maintenance costs – reduces dusting and absorption, therefore floors are easier to clean. 
  • Protects against joint deterioration – minimises damage to production goods and increases the life of material-handling equipment.

Surface Preparation

Monolithic Application: 

Ensure that there is no bleed water present. The surface must have reached an “initial set” in order to walk on to render the surface “open” with a wooden float. 

Previously Cured Concrete Application: 

To achieve proper bond of abe.®top the surface of the concrete should show a 5mm profile. All laitance and contaminated areas must be removed; coarse stone and the aggregates shall be exposed. This is best achieved by multiple passes with a shot blast machine with heavy shot, a scabbler or scarifier.

The concrete surface should be tested for tensile bond pull off strengths per a.b.e.® Construction Chemicals recommendations. The minimum tensile bond pull off strength shall not be less than 2.00MPa and substantial coarse aggregate fracture shall be revealed. 

All surface defects may be patched with dura.®rep FR


  • Do not apply abe.®top topping over fresh concrete containing calcium chloride, aggregate contaminates with salt water or more than 3% entrained air or in bleed water. 
  • Use only potable water when mixing abe.®top topping. 
  • Under no circumstances must a latex product be used with abe.®top or in the bond coat.
Bonding / Priming

Monolithic Application: 

No bond coat required when placing monolithically at 13-25mm thickness. 

Previously Cured Concrete Application 

Bond coat: epidermix 116 or epidermix 344. 


Using a forced action pan mixer, add . of the mixing water followed by the abe.®top in a slow, steady stream, then mix for approximately two to three minutes. Add remaining water and continue mixing for a total of five minutes, for a homogenous mix at the recommended slump. 


One 25 kg bag of abe.®top topping mixed with 2,5L of water provides approximately 6,5L of topping. This amount will cover approximately 0,25m2 at 25mm thickness.

Rate of Use

Use approximately 100 kg/m. to produce a 25mm thick topping. For thinner toppings, see precautions. 

Note: Contact the local a.b.e.® representative for information on application procedures, suggested armouring thicknesses and service. 

Recommended Thickness
  • 25mm and over, for impact and abrasion resistance – cement slurry bond coat required on set slab. 
  • 19mm – 25mm, for impact and abrasion resistance – epoxy bond-coat required on set slab. 
  • 13mm – 19mm, for abrasion resistance, and impact – epoxy bond coat required on set slab.

Discharge the topping from the mixer for immediate placing and screeding. If lumps are present, remove. 

Because of the relatively low slump of abe.®top, a roller or pipe screed is the preferred method for obtaining a uniformly flat, dense surface without excessive segregation from vibration. Tamp the topping thoroughly with a jitterbug to consolidate and ensure contact with the bond surface. As soon as the abe.®top will support an operator and machine without leaving impressions on the slab or creating excessive fines at the surface, float with a mechanical trowelling machine equipped with float shoes. For small areas, floating with hand tools is acceptable. Following one machine floating, proceed with one or two normal trowelling operations to obtain a hard steel trowel or burnished trowel finish. Trowelling operations should be timed and blade angle adjusted to avoid blistering. Periodically measure the topping thickness, especially in the centre of the slab. 

As soon as the surface will not be marred, immediately apply abe® membrane curing compound such as dura.®cure SBC

Cleaning of Equipment

Water before dried/cured.

Protection on Completion

Protect surface against traffic and spillage until cured.

Temperature & Relative Humidity

As for concrete work.
