Step-by-Step Instructions
1
Empty and Clean the Tank
- Use a submersible pump to empty the water from the tank completely.
- Wash or water-blast the entire interior surface to remove dirt, algae, old silicon/sealant and debris.
- Use a wet/dry vacuum to remove any remaining water.
- Ensure the surface is completely dry before proceeding.
2
Reinforce Vulnerable Areas
- Identify cracks, holes, corners, and wall-floor joins.
- Pre-cut Geo-Textile to bridge these defects.
- Apply a first coat of Waterproof Sealant to these areas using a brush or roller. While the sealant is still wet, embed the Geo-Textile into the sealant, ensuring there are no air bubbles or wrinkles. Brush out any air pockets for a smooth application.
3
Seal Key Areas
- Apply Waterproof Sealant to pipe outlets and areas just above the maximum waterline (do not coat the roof of the tank).
- Use Rapid Cure Spray to instantly set the product and accelerate the job. Ensure the Rapid Cure Spray is fully dry before proceeding to the next step.
4
Apply Additional Coats
- Apply a second coat of Waterproof Sealant to all reinforced areas, including cracks, joints, and corners.
- If fully encapsulating the entire tank interior, apply additional coats as needed to achieve a dry-film thickness of 1.5mm - 2mm (approximately 2 litres per square meter).
5
Cure Before Refilling
- Allow the Waterproof Sealant to cure for a minimum of 7-10 days before refilling the tank. Longer curing times are recommended in colder weather to ensure proper bonding and durability.
- Use a fan-forced ventilator to ventilate the tank and accelerate the drying process.
