MIXING
Waterproofing
Mix the required amounts of Sika® Cemflex® and water first, add the correct quantity of Portland cement slowly, while mixing, to avoid the formation of lumps.
Mixing can either be achieved manually or mechanically, with small quantities of 5litres and less. Larger quantities should be mechanically mixed with a slow speed mixer (set at 400-600 rpm). Mixing should continue until a uniform, lump-free consistency is obtained. The slurry should be mixed periodically during application to prevent settlement.
Bonding/Bagging mixing
Sika® Cemflex® and water are mixed in equal proportions by volume. Mix clean building sand with Portland cement in equal proportions by volume and then add sufficient diluted Sika® Cemflex® and continue mixing until a uniform, lump-free consistency is obtained. Mix periodically during application to prevent settlement.
