4201 MASTAR 10 Self Leveling Screed

TECHNICAL DATA SHEET

Description
Self leveling flooring compound, smoothing the differences in thicknesses from 2.5 to 10 mm on new and
existing interior floors where a high resistance to loads and traffic is required.
Fields of Application
• Leveling concrete slabs and cementitious screeds.
• Under wood, laminate parquet, carpet, PVC, linoleum and ceramic flooring.
• For floors subject to high loads and heavy traffic like depots against dusting and abrasion.
Properties
• Perfectly self leveling.
• High adhesion strength.
• Can be spread in thicknesses up to 10 mm per coat without shrinkage, cracking or crazing.
• Develops very high compressive and flexural strength.
• Resistant to abrasion.

Preparation of Substrates
• The substrate must be solid, dry, free of dust, loose parts, paint, wax, oils, rust and traces of gypsum.
• The substrates to be coated should be free of adhesion preventive foreign substances such as dust, dirt,
mould oil, paint etc.
• The sub-surfaces that are not strong enough to carry themselves e.g. cracked plasters, weak surfaces, or
residues of moss should be cleaned from the application surface.
• Use Tamirart series repairing mortars in case of any loose and uneven substrates to get a sound and flat
surface.
• Dusty and very porous concrete surfaces must be treated with Kalekim Astar (Primer) or B-Tone.
• Polystyrene foam should be placed to separate the self leveling screed from walls or other structural
elements, to avoid the risk of cracking during drying of the screed due to expansion.
• In order to prevent leveling difference at large areas, application should be done by determining maximum
3x3 meter sized areas.
• Application thickness should be determined according to the surface smoothness
