NUMBER 1 : is a unique chemical treatment for the waterproofing, protection and repair of concrete. The barrel 5kgs is ideal for small projects. NUMBER 1 : is the most chemically active product within the Crystalline Waterproofing System. When mixed with water, this light grey powder is applied as a cementitious slurry coat to above ground or below ground concrete, either as a single coat or as the first of a two-coat application. It is also mixed in Dry-Pac form for sealing strips at construction joints, or for the repairing of cracks, faulty construction joints, and honeycombs. NUMBER 1 : prevents the penetration of water and other liquids from any direction by causing a catalytic reaction that produces a non-soluble crystalline formation within the pores and capillary tracts of the concrete and cement-based materials. Advantages: - Less costly to apply than most other methods - Can be used on damp substrates - Resists extreme hydrostatic pressure - Becomes an integral part of the substrate - Can seal hairline cracks up to 0.4mm - Allows concrete to breathe - Chloride-free - Highly resistant to aggressive chemicals - Non-toxic - Does not require a dry surface - Cannot puncture, tear or come apart at the seams - No costly surface priming or leveling prior to application - Does not require protection during backfilling or during placement of steel, wire mesh or other materials - Not subject to deterioration - Permanent Application: - Reservoirs - Sewage and Water Treatment Plants - Underground Vaults - Secondary Containment Structures - Foundations - Tunnels and Subway Systems - Swimming Pools - Parking Structures and Roof Decks Colour: Grey Shelf Life: 09 months Packaging: 25kg/barrel and 5kg/ barrel
