Water based penetrating sealer
Finseal Invisi WB is a clear impregnating low VOC sealer that is designed to protect concrete, absorbent natural stone and masonry surfaces. Finseal Invisi WB is a water-based formulation containing a fluoro-acrylic modified microemulsion that has good penetration and is fast drying. Treated substrates are UV stable, hydrophobic and resist staining from ingress of, oils, salts, organic matter, food and beverages.

Ensure substrate is clean, dust and stain free prior to application. Clean surface to remove any dirt, laitance, previous coatings or curing agents that may prevent penetration of the material.
The surface must be dry prior to application.
Confirm absorbency of surface with a light water spray, ensuring penetration into the surface is achieved.
It is recommended to undertake a test sample to confirm the suitability of the product for specific substrates and ensure desired results are achieved.
Slowly stir the material until thoroughly mixed; Using a low-pressure sprayer fitted with an adjustable spray tip, surface must be flooded at a sufficient rate ensuring to achieve full saturation.
Substrates of greater porosity will benefit from a second application, wet on wet, to ensure penetration is achieved. The properties of the substrate such as porosity and profile will greatly influence the amount of material required.
