- Technology
HydroBlok is a proprietary aqueous solution with special penetrating agents that help deep sealing of concrete that has severe moisture problems, sluffing or dusting (Chalking).. Ready-to-Use Products
- Application
- Hudson or Airless
- Labeling Claims
- Non-Flammable
- Primary Benefits
- Rapid performance.
- Precipitates calcium ions.
- Vapor permeable.
- Reduces freeze/thaw spall.
- UV resistant.
- Stops seepage.
- Stops moisture migration.
- Hardens and increases strength.
- Surface Preparation
All concrete must be clean, raw concrete, no paint or sealers. To remove algae spray down with a 50/50 mixture of Clorox and tap water. Deck brush and hose or mop down to rinse. Allow area to semi dry and apply HydroBlok with a inexpensive low-pressure (garden type) pump sprayer that you can use for both products.. Note: Always wet the block wall down with water before applying HydroBlok sealer. A good damp spray is adequate. Do not over saturate.
- Application Instructions
Note: If a wall render is to be applied wall must be free of all residual sealer by scrubbing with and deck brush and water 24 to 48 hours after last application of HydroBlok–OR–apply the HydroBlok in smaller sections using 3 consecutive applications. While the wall is still damp from the sealer apply the wall render. See wall render instruction included with your shipment.
