Corrosion blocking waterproofing mortar based on crystalline activated cement and passivating extenders
CrystalSkim is a blend of cements, pozzulanic extenders, fine sand, microcrystalline waterproofing additives, wetting aids and powder polymers.
Mixed with water to an easily trowelable consistency, CrystalSkim produces a thixotroptic mortar which does not slump off vertical or overhead surfaces easily.
Applications:
CrystalSkim wet mortar responds well for easy smoothing and thin applications. It is one component, only needs water added. CrystalSkim contains polymers and therefore need not be water cured. CrystalSkim protects and passivates corroded reinforcing bars.
The elastic modulus of hardened CrystalSkim is lower than that of cured concrete and therefore CrystalSkim bridges minor cracks and has no thermal expansion incompatibility with hardened concrete (Between 10 and 14-6 mm/oc)
CrystalSkim is breathable, allowing passage of moisture vapour, but watertight to liquid water.
CrystalSkim is ideal for the repair of areas subject to rising damp.
Used with P3 Primer X, CrystalSkim passivates corroded steel and provides a blocking mortar which arrests ingress of chlorides, sulphates, and blocks carbonation at the surface.
Yield:
Mixed with about 16 % water each 2 kg of CrystalSkim powder will yield about 1 litre of plastic mortar.
16% water addition by weight.
4 Litres of water / 25kg bag.
Skill Level Required: 4/5
