FAQs

Can this tanking slurry be used below ground?

No, the Bostik Sovereign Tanking Slurry is specifically designed for above-ground masonry applications.

How much water should I add to the 20kg bag?

Typically, 4.5 to 5.5 liters of clean water are added per 20kg bag, but always refer to the specific mixing instructions on the product packaging for precise amounts.

What tools are best for applying this slurry?

The slurry can be applied using a stiff brush or a spray application system, depending on the surface area and desired finish.

How long does the mixed slurry last once prepared?

Once mixed, the slurry should be used within 1 to 2 hours, as it will begin to harden.

Can I apply this over painted or rendered surfaces?

It is recommended to remove any loose paint, render, or coatings. The surface should be sound, clean, and dry masonry for optimal adhesion.

What is the coverage rate?

Coverage rates vary depending on the application thickness and surface porosity. Refer to the product's technical data sheet for estimated coverage.

Is this product suitable for exterior use?

Yes, it is suitable for above-ground masonry, which can include exterior walls, providing a protective barrier against dampness.

Troubleshooting

Slurry is too thick or lumpy

Add a small amount of water and mix thoroughly. Ensure water is added gradually during the initial mixing stage.

Slurry is too thin

Add a small amount of the dry powder and mix thoroughly. Be cautious not to overcompensate.

Poor adhesion to the surface

Ensure the masonry surface was adequately prepared, clean, dry, and free from dust or efflorescence before application.

Application is difficult

Check the water-to-powder ratio. Ensure you are using the appropriate application method (brush or spray) for the surface and consistency.

Setup, Compatibility & Care Instructions

Setup: To prepare the Bostik Sovereign Tanking Slurry, empty the contents of the bag into the provided bucket. Gradually add clean water while continuously mixing with a mechanical mixer or by hand using a suitable paddle. Aim for a creamy, lump-free consistency, similar to thick paint. The recommended water addition is typically around 4.5-5.5 liters per 20kg bag, but always follow the specific instructions on the packaging. Ensure the masonry surface is clean, dry, and free from loose debris or contaminants before application.

Compatibility: This product is designed for use on above-ground masonry structures. It is compatible with most common building materials used in masonry construction. Avoid application on surfaces that are consistently saturated or below the water table.

Care: Store the product in its original, sealed packaging in a dry environment. Once mixed, the slurry should be used within 1-2 hours, depending on ambient temperature, as it will begin to set. Clean tools and equipment immediately after use with water. Cured material can be difficult to remove.
