Product description

Cement based, polymer reinforced rapidly hardening waterproof and frostproof dry concrete. Low dust.

 

Application areas

For casting concrete floors/screeds and unbonded and floating screeds, repairs of holes and depressions and reinforcement of anchors, columns etc. in wet and dry areas, indoors and outdoors.

 

Types of substrates

Use 6998 betomix quick as bonded screed in a 20-80 mm thick layer on concrete substrates. Apply 6998 betomix quick as floating screed (layer thickness 35-80 mm) without a reinforcement mesh on solid substrates with a slip layer or with a reinforcement mesh and a slip layer on substrates like insulation. The slip layer is made of 2 x 0.15 mm PE plastic film.

 

Pre-treatment of substrate

The substrate must be firm, sound, coherent and free from dust, grease and cement laitance. Any hardened laitance and weak parts of the concrete surface must be cut off or ground away. Loose dust to be removed with vacuum cleaner. Grease, oil etc. to be removed using 7110 base cleaner, high pressure water cleaning or other effective cleaning method.

 

Priming

Priming is usually not necessary.
For bonded screed less than 30 mm thick 6998 betomix quick bonding must always be secured by a slurry bonding coat: 1 part 4180 primer mixed with 2 parts water and added 6998 betomix quick powder to create a mixture with right viscosity.

 

Application

25 kg 6998 betomix quick powder to be mixed with 1.8-2.2 l clean water to a lump free mass. Small portions can be mixed with a low-speed mixing paddle. Large portions are mixed in a concrete mixer. Ensure that the powder and water are within the recommended working temperature.

The pot life of the mixed product is approximately 40-60 minutes after mixing at room temperature of 10-18°C.

Pour compound onto the floor immediately after mixing and work it throughly into substrate. Level the compound.

All areas above 30-36 m² must be divided into smaller areas with expansion joints across the construction. Any reinforcement mesh/ bars must be cut at the expansion joints.

After 1-1,5 hour the compound starts to set and can be float finished and smoothened.

The surface is ready as finished flooring or for further surface treatment after 3 hours.

The newly cast mortar must be protected against forced drying out during the curing process.

 

Working environment

The product contains cement. Working hygienic rules for cement must be followed.

6998 betomix quick is guaranteed chrome neutralised for at least 12 months.
