HYPASTAT is the strongest commercially available sodium hypochlorite (bleach) formulation at >16% concentration, designed for deep cleaning and sanitising masonry surfaces prior to sealing. Ideal for use on: Concrete paths Concrete blocks & walls Oamaru stone Other masonry surfaces Note: HYPASTAT is a powerful pre-sealer cleaner and sanitiser. It is not an effective long-term moss control product. Mixing & Coverage Instructions: Mix Ratio: 1:2 — 1L of concentrate mixed with 2L of water 20L makes 60L of mixed solution, treats approximately 180 m² Application: Apply mixed solution by sprayer to the surface. Allow 1–2 hours for the product to react with the substrate, then rinse off thoroughly using a low-pressure water blaster with a wide fan nozzle. As the product rinses off, dries, and reacts with UV, the surface will come clean — as close to original condition as reasonably expected. A repeat application may be required on south-facing or heavily shaded areas. Safety: Place a drop sheet over plants near the treated area — HYPASTAT will burn vegetation on contact (plants typically recover) Wear gloves, safety glasses, and a P2 mask at all times After treatment: Once the substrate is fully dry, sealing with AQWB or Strata Nano is strongly recommended Download the product application guide and safety data sheet
