< 85%

25°c- 90min

35°c- 45min

Full cure at 7 days

Allow a minimum of 6 hours and a maximum of 48 hours curing prior to the application of Sika® liquid applied waterproofing membranes. In case the overcoating interval of 72 hours has been exceeded, apply a further coat of Sikalastic® Moisture Seal to reactivate and extend overcoating interval.

MOISTURE BARRIER COATING: A minimum of 2 coats shall be applied at 3m2 per Litre per coat

PRIMER: 1 coat is required at a rate of 10m2 per Litre per coat

All surfaces to be waterproofed must be firm, clean, dry, structurally sound and smooth. All grease, oil, wax, curing compounds, dust, loose material, laitance and other contaminants must be removed. All projections and rough spots should be dressed off to achieve a level surface. The substrate surface must be continuous. Substrates that have been previously treated or coated with curing compounds, bonding agents or other coatings must be mechanically prepared and washed to produce a contaminant-free surface.

Sheeting

All sheeting must be fixed in accordance with manufacturer's installation directions.

Concrete

Concrete must be allowed to cure for a minimum 72 hours and cement render and sand and cement screeds must be allowed to cure for 24 hours prior to the application of Sikalastic® Moisture Seal. Surfaces must be even and smooth, imperfections must be repaired with a suitable Sika® MonoTop repair mortar.

Prior to application thoroughly stir Part A and Part B with separate implements. Measure equal volumes of Parts A and B and place into a clean container. Using a mechanical mixer, thoroughly mix together to produce a homogenous liquid. Use care to avoid air entrapment into the mixture. Do not mix more product than can be used in within 90 minutes at 25°C.

Remove liquid coating immediately with a dry cloth, clean tools and equipment with water while the material is still wet. Cured coating can only be removed mechanically.
