Stone cladding can add a touch of elegance to any space, but ensuring its longevity and resistance to the elements is crucial. Enter VenSeal Ultra WB, a cutting-edge waterborne mixture designed to impart water and oil repellency to inorganic substrates such as concrete and masonry. In this article, we’ll delve into what VenSeal Ultra WB is, why you might need it for your stone cladding projects, and how to apply it for optimal results.

What is VenSeal Ultra WB?

VenSeal Ultra WB is a waterborne mixture of silane, siloxane, and synthetic resins, carefully formulated to provide water and oil repellency to surfaces like concrete, masonry, and stone. The product is especially recommended for use on floors, window sills, table tops, and facades made of natural or synthetic stone, unglazed ceramic tiles, or fibrous cement.

Top 5 Points from the VenSeal Ultra WB Info Sheet

Composition:

VenSeal Ultra WB is a combination of silane, siloxane, and synthetic resins to impart water and oil repellency to inorganic substrates.

Recommended Applications:

Ideal for use on floors, window sills, table tops, and facades made of natural or synthetic stone, unglazed ceramic tiles, or fibrous cement.

Coverage Rate:

Approximately 3-4 square metres per litre per coat, depending on the porosity of the substrate. Two flood coats are recommended for a minimum effective treatment.

Packaging Options:

Available in 5-litre jerry cans, 15-litre cubes, and 200-litre drums.

Typical Properties:

White liquid appearance, invisible penetrating sealer finish, specific gravity of approximately 1.0 kg/l, viscosity of approximately 100 cps, potlife of indefinite, recoat time of 2 hours at 25°C, full cure time of 24 hours at 25°C, weight solids of 7 +/- 1%, and VOC (APAS D181) of 45 +/- 5 g/ltr.

Can VenSeal Ultra WB be Diluted?

No, VenSeal Ultra WB should not be diluted. The product explicitly states “DO NOT DILUTE” under the Mixing section in the Data Sheet.

Recommended Substrates for VenSeal Ultra WB

The recommended substrates for VenSeal Ultra WB include in-situ concrete, masonry, stone, and terrazzo.

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.

Mixing:

Use VenSeal Ultra WB straight from the container without dilution.

Placing:

Apply the product using a low-pressure sprayer. Remove excess material with a broom or microfibre 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.
