MasterLife WP 730 is a high-performance, water-based, hydrophobic admixture designed for concrete. Manufactured by Master Builders Solutions (formerly BASF Construction Chemicals), this product is not a simple surface coating—it is an integral water repellent. When added during the batching process, it dramatically reduces the capillary absorption of water and aggressive chemicals into the concrete matrix.
MasterLife WP 730 is compatible with:
| Problem | Likely Cause | Solution per Datasheet | | :--- | :--- | :--- | | No water repellency | Under-dosage (<0.5%) | Increase to 1.0% minimum | | Air entrainment instability | Interaction with air-entraining admixture | Add AEA after WP 730; increase dosage of AEA | | Slump loss | Late addition of WP 730 | Add during initial mixing, not after slump achieved | | Variable surface finish | Incomplete mixing | Extend mixing time by 60 seconds | masterlife wp 730 datasheet

MasterLife WP 730 (formerly known as Rheomac 730 ) is a liquid, chloride-free hydrophobic pore-blocking ingredient (H.P.I.) specifically designed to reduce water absorption in concrete. It reacts with the cement hydration process to create an integral hydrophobic barrier that limits capillary suction and prevents the ingress of harmful soluble materials. Note: Due to rebranding, this product is also known as SikaControl-730 WT Key Technical Specifications Specification Colourless, clear to slightly cloudy liquid Chloride Content Chloride-free (per EN 934-2 / BS 5075) Water Absorption < 1% at 7 days (BS 1881: 122) Approximately 13 (at 20°C) Approximately 1.02 g/cm³ Typical Dosage 1.0 to 2.0 litres per 100kg of cement Applications & Usage It reacts with the cement hydration process to
By understanding the dosage rates, compatibility notes, and performance curves outlined in the datasheet, engineers can design concrete that actively repels water, chlorides, and sulfates without altering the aesthetics or mechanical properties of the structure.
