PREMIUM SELF LEVELLING COMPOUND KEY BENEFITS • Ready for laying after 12 hours • Particularly smooth surface • Good workability in thin layer • Perfect flow • Pumpable with PUMP TRUCK • Suitable as a substrate for parquet laying APPLICATIONS DESTINATION PRODUCT CHARACTERISTICS Composition / colour Cement / grey powder SL C710 BEST is a self levelling compound for use on internal floors.
• Fast drying floor screeds • Rough concrete ceilings • Especially on critical substrates : water Mixing ratio Application temperature 6,75 liters of water per 25 kg bag Between +15°C and +25°C resistant adhesive residuals • Under parquet floors • Ceramic tiles • Natural stone • Hard and solid substrates The self levelling compound can also be used in industrial use rooms (especially with forklift traffic) with subsequent application of a suitable coating.

Can be applied in layer thicknesses of 1-15 mm.


Suitable for layer thicknesses of 2 to max.

5 mm on mastic asphalt screeds.

It can be used, upstretched, in a layer thickness up to 20mm.

For use in damp and wet-rooms in combination with Bostik an waterproofing system.

appropriate Working time* 40 minutes Walk on time* 2-3 hours Curing time* After approx.
2-3 hours Application thickness From 1-15 mm Coverage 1.5 kg/mm/m² Compressive strength C30 Flexural strength F7 *these times are determined at + 23° C and 50 % relative humidity on normally absorbent substrates SUBFLOOR PREPARATION CLEANING PREPARATION In accordance with the requirements of DIN 18365, DIN 18352 and DIN 18356, the substrate particularly permanently dry, clean (free of dirt, oil, grease, wax and other separating agents), crack-free, resistant to tension and pressure and not too smooth or too rough.
The following substrates must be pre-treated with the following primers or bonding agents : In case of needing a second layer of SLC 710 Best, apply an intermediate apply an intermediate primer such as GRIP A500 MULTI (water diluted 1:1).

The thickness of the following layer has to be maximum 1/3 of the existing and cured layer SLC 710 Best.

It is absolutely required to protect the curing layers from drying too quickly; e.g.

do not expose them to direct sun radiation, draught or high room temperatures.
Before laying the floorings, ensure that the levelling layer is completely dry.
AREAS OF APPLICATION ASSOCIATED PRIMERS Highly absorbent cement screed GRIP A500 MULTI COVERAGE 1.5 kg/mm/m² Calcium sulphate screed or Calcium sulphate floating screed GRIP A500 MULTI STORAGE STABILITY Mastic asphalt screeds, swept, vacuumed GRIP A936 XPRESS / GRIP A500 MULTI Magnesia screed, mineral filled HYTEC E730 XTREM sand well / GRIP A936 XPRESS / HYTEC P510 RENORAPID sans well Terrazzo, stones tiles and other smooth and dense substrates GRIP X910 FILL & WOOD / GRIP A936 XPRESS When priming absorbent, cementitious substrates with diluted GRIP A500 MULTI.
the prepared sublfloor can be self levelled direct after stepability of the primer.

In other cases, especially CA/CAF screeds you need longer curing times.

Please note the according TDS.

METHOD OF USE Fill a clean bucket with cold and clean water.

Stir the levelling compound powder into the water with an appropriate mixer and paddle until a homogeneous consistency is reached.

A ripening time of at least 2 minutes is recommended.
Apply the levelling compound onto the subfloor within the operating time and smooth it with a trowel.

To achieve the best possible evenness, we recommend using a spreading knife.

Thicker layers are deaerated with a porcupine roller.

For layers above 15 mm (until 50mm under ceramic tiles) thickness it is necessary to add sand as mentioned below.

Stir sand as last component.
