Base requirements and coating conditions

The concrete strength class must be at least C25/30 with a wear resistance class of 3. The relative humidity of the concrete must be below 95%, and the surface temperature must be at least +3°C above the dew point. During application and curing, the temperature of the air, surface, and coating must remain above +15°C, and the relative humidity of the air must be below 80%. 

New concrete floor

Cement laitance and any uncured cement must be removed by surface grinding or shot blasting. All loose and adhesion-reducing material must be removed, and the surface must be thoroughly vacuumed to remove all cement dust.

Old concrete floor

Cement laitance and deteriorated concrete must be removed by grinding or shot blasting. All loose and adhesion-reducing material must be removed, and the surface must be thoroughly vacuumed. Dirty floors should be washed and rinsed with a synthetic detergent before any further surface preparation. Any existing old paint film must be completely removed from the substrate.

Priming 

Priming is done with Nanten HM Bio Epoxy. The primer must seal all pores in the concrete so that a dense and continuous film is formed on the surface. Adhesion sand is broadcast onto the primer as work progresses.'

Patching

Small holes and cracks are cleaned and filled with an epoxy putty made of, for example, HM Bio Epoxy and fine filler sand. Larger or more extensive overfills, leveling, and slope formation can be done using a filling/levelling mortar made of Nanten HM Bio Epoxy and filler sand (0.1–0.6 mm).

Mixing

Pre-mix Part A and Part B of HM Bio True Colors Epoxy in their own containers. Estimate the required amount of mixture based on the size of the area to be treated and the working time of the product. Combine the components in the correct ratio and mix with a low-speed mixer for approximately two minutes, avoiding air entrapment in the mixture. Add the required amount of precision-graded sand while mixing, and continue mixing for about one minute.

Mixing ratio

Part A: 2 parts by volume, Part B: 1 part by volume

Coverage  

At 4 mm film thickness
For priming: 0.2–0.3 l/m²
For top coating: 0.35–0.45 l/m²
Resin consumption: approx. 1.3 l/m²

Coating

The mixed material (HM Bio True Colors Epoxy + filler sand) is poured onto the floor in a continuous bead and spread with a notched trowel to the desired thickness. Application is carried out in strips, allowing surface finishing from untreated areas of the floor. After spreading, the material is compacted manually with a steel trowel or mechanically by power troweling to achieve a smooth surface. At 4 mm film thickness, the consumption is approx. 1.3 l of HM Bio True Colors Epoxy and approx. 7 kg of filler sand per m².

Top coating

Once cured, the compacted trowel-applied coating must be sealed with thinned True Colors Epoxy. We recommend applying two coats to achieve a hygienic and easy-to-clean surface.
