WATERPROOFING SYSTEM
RAYCOAT hydroproof slurry cementitious crystallization
Permanent Waterproofing. Crystalline Protection. Lasting Durability.
A two-component crystalline waterproofing system that penetrates concrete surfaces to form insoluble crystals, blocking water passage and providing long-term protection against water ingress and seepage.
- Permanent waterproofing protection
- Effective against positive and negative water pressure
- Reactivates upon contact with water for added protection
- Suitable for water tanks, basements, tunnels, and concrete structures

RAYCOAT HYDROPROOF SLURRY is a 2-component crystalline waterproofing formulation of selected blends of cement, very fine treated silica
sand and various active chemicals providing a long-lasting impermeability to water. Hydroproof Slurry provides a permanent solution to water
leakage, ingress or seepage in cementitious substrates. The liquid emulsion acts as an excellent bonding agent to ensure high adhesion
strength to the substrate to withstand high hydrostatic pressure. It has a unique chemical treatment for the waterproofing and protection of
concrete. The formation and development of insoluble crystals into water bearing capillaries and interstices effectively blocks the further
passage of water and ensures permanent watertightness for the life of the structure. This crystalline growth reduces porosity by blocking
capillaries and filling hairline, non-structural cracks caused by shrinkage or expansion.
SURFACE PREPARATION
Concrete surface to be treated must be clean and free from laitance, dirt, paint coating and other foreign matter. Remove existing coatings, smooth surfaces or laitance by acid etching, water blasting or sandblasting. Structural defects such as cracks, faulty construction joints and honeycombing should be routed out to sound concrete and repaired with hydroplug (see separate data sheet).MIXING & CURING
Mix the liquid component with the powder component. Mix thoroughly using a slow speed electric drill fitted with paddle for 3-5 minutes until desired homogeneous paste is achieved. Allow the mix to rest for 3-5 minutes to allow chemical reaction. It should then adhere to the brush without dripping. If the mixture thickens, re-stir to restore workability. Do not add extra water. Proper curing procedures are important to ensure the durability and quality. To prevent surface cracking, curing must begin as soon as the Hydroproof Slurry has reached initial set. Moist curing using continuous water spray is recommended, Keep treated surfaces moist during curing by spraying surfaces with a fine mist of water three times a day for 2-3 days (under moist conditions). In warmer climates, more frequent spraying may be requiredPRODUCT FEATURES
