Preparation of Previously Treated or Coated Areas

Before applying VenSeal Ultra WB over previously treated substrates, it’s crucial to clean the areas by pressure cleaning. This ensures a contamination-free surface, promoting proper adhesion of the sealer and preventing issues from previous treatments or coatings.

How to Apply VenSeal Ultra WB

Follow these steps for optimal application:

Surface Preparation:

Ensure the surface is dry and free from contaminants. Moss or algae growth should be treated with a biocide after grit blasting. Allow the surface to stand for at least 24 hours before applying VenSeal Ultra WB, adhering to recommended recoat times.


Use VenSeal Ultra WB straight from the container without dilution.


Apply the product using a low-pressure sprayer. Remove excess material with a broom or microfiber mop, ensuring an even coating. Avoid contact with surrounding areas.

Note: Do not apply VenSeal Ultra WB over substrates previously treated with curing compounds, PVA concrete bonding agents, or acrylic coatings. Mechanically clean these areas before application.
