EVERBUILD OPTI-MIX INTEGRAL WATERPROOFER is a versatile, all-in-one solution that functions as a plasticiser, waterproofing agent, and salt inhibitor. This concentrated formula is easy to use and ensures consistent results with no waste, providing 25 times the coverage of standard waterproofers (1L = 25L of standard waterproofer). It improves the water resistance of mortars, enhances workability, and offers protection against freeze/thaw cycles, making it an ideal choice for construction projects.
Key Points:
- Improves Water Resistance – Boosts the water resistance of mortars for more durable finishes.
- Enhanced Workability – The added plasticising agent makes mortars easier to work with.
- Freeze/Thaw Resistance – Provides long-term durability in environments with freeze/thaw cycles.
- Reduces Bleeding – Helps to prevent excess water separation, ensuring a smooth, uniform mix.
Shelf Life & Storage: The shelf life is 12 months from the date of manufacture. Store in the original, unopened containers at temperatures between 5°C and 40°C.

OPTI-MIX INTEGRAL WATERPROOFER is suitable for pool and tank linings, external renders, external pointing, and structures below ground level, providing durable and long-lasting protection.
Application Method
Before use, shake the bottle well. To open, push the lid down and twist it counterclockwise. Squeeze the sides of the bottle to measure the required dose (20-40ml per 50kg of cement). Mix EVERBUILD OPTI-MIX INTEGRAL WATERPROOFER into water and stir thoroughly. Prepare a dry mix of all other ingredients, then gradually add the water/OPTI-MIX solution until the desired consistency is reached. Always dilute the product in gauging water—never add directly to dry mix. Replace the cap after use.
Limitations
- Do not exceed the recommended dosage rate and avoid overmixing.
- Store the container upright during storage and transit.
- Not suitable for structural concrete due to its air-entraining formulation.
- Ensure materials and methods align with BS8000 Part 10 1995 for external rendering.
- Dispose of product and packaging responsibly; do not let it enter watercourses.
- Always read the label before use and wear appropriate protective gear. For suitability questions, contact the Technical Services Department.
