Sika® universal product SikaScreed® LS-5

SikaScreed® LS-5 is a new universal product for earth-moist cement screeds to improve heat transfer and advance the heating start of heated screeds as well as to improve flexural, compressive and tensile bond strengths for subsequent coatings.

• Excellent workability - simplified leveling and smoothing of the screed
• at least 45 minutes processing time
• Unlike conventional additives, does not introduce air and thus improves the flexural, compressive and, above all, adhesive tensile strengths
• Reduction of screed thicknesses of floating screeds by doubling the flexural tensile strength
• early load-bearing capacity of the screed
• Earlier coatability of unheated screeds (< 4 CM-% after max. 7 days)
• Tensile bond strength > 1.5 N/mm² for all types of coatings
• improved heat transfer in heated screeds by improving the compaction capacity of the screed
• shortening the waiting time until the covering is ready for heating
• Guaranteed, standard-compliant readiness of heated screeds after 7 - 10 days or 14 - 18 days (< 1.8 CM-% without deduction!)
• Low shrinkage and low stress hardening - reduced cupping of the screed
• biologically harmless: no formaldehyde, no solvents or other volatile compounds
• Density: ~ 1.03 kg/liter
• pH value: ~ 5.5 ± 0.5

• Color: bluish
• Container: canister
• Brand: Sika
