The NEOSEAL CRYSTALLINE is a waterproofing coating that ensures the total and permanent solution to water leakage, ingress or seepage in concrete structures or any cementitious substrate. The formation and development of insoluble crystals into
water-bearing capillaries effectively blocks the further passage of water and ensures permanent water tightness for the life of the structure.
Supplied as a powder and mixed to a slurry consistency with water. NEOSEAL CRYSTALLINE is applied directly to concrete, block work or cement renders in areas where general waterproofing is required. In powder form, the product may be used as a dry shake on horizontal construction joints.
Compressive Strength after 28 days (ASTM C579) > 20N/mm2
Bonding Strength to concrete after 28 days (EN 1542) > 1.0 N/mm2
Chloride Ion Content ≤ 0.03%
Water Pressure: Can resist up to 5 bar of water pressure
Resistance to fire (BS 476-7): Class 1
NEOSEAL FLEX 588 is available in 25 Kg Bag.
Always add water to NEOSEAL CRYSTALLINE – not in reverse order.
Mix 1 part of water to 2.25-2.5 parts NEOSEAL CRYSTALLINE powder by volume.
NEOSEAL CRYSTALLINE is applied by brush or spray onto the dampened substrate. Apply the material in 2 coats at right angles; apply the second coat whilst the first is firm, but “green” – usually 3-4 hours after first coat (dependent on temperature).
