Product Information

Full details

This guide is for homeowners and DIY enthusiasts looking to protect exterior surfaces like wood, brick, stone, and concrete from water damage. Thompson's Water Seal Clear offers a key benefit of reducing water penetration while remaining virtually invisible, providing protection without altering the material's appearance. A potential caveat is that results can vary depending on the surface's condition and preparation. This treatment penetrates materials to create a breathable barrier, helping to prevent common issues like cracking, staining, and mold growth caused by excess moisture. It's designed for general outdoor surface maintenance and can be applied via brush, roller, dipping, or low-pressure spray.

FAQs

What surfaces can Thompson's Water Seal Clear be used on?

It is suitable for exterior wood, brick, stone, and concrete surfaces.

Will this product change the color of my surface?

No, Thompson's Water Seal Clear is designed to dry clear and preserve the natural appearance of the material.

How many coats should I apply?

Typically, two coats are recommended for best results, depending on the porosity and condition of the surface. Allow the first coat to absorb before applying the second.

How should I clean my tools after using this product?

Tools should be cleaned with white spirit immediately after use.

When is the best time to apply this product?

Apply when the surface is clean and dry, and when no rain is expected for at least 24-48 hours to allow for proper curing.

How long does the protection last?

The duration of protection varies depending on environmental conditions and surface wear. Reapplication may be necessary over time.

Can I apply this product on a damp surface?

No, for optimal performance and to prevent issues like cloudiness, the surface must be clean and completely dry before application.

Troubleshooting

Surface still absorbs water after application

Ensure the surface was thoroughly cleaned and dried before application. Reapply a second coat if the surface is highly porous or if the first coat was not fully absorbed.

Uneven finish or water beading

This can occur if the product was applied too heavily or unevenly. In some cases, light sanding after curing might help, or a reapplication after the surface has fully dried may even out the appearance.

Product appears cloudy or milky

This is typically a sign of moisture trapped beneath the surface. Ensure the surface was completely dry before application and allow adequate drying time in good weather conditions. Avoid application if rain is expected.

Difficulty cleaning application tools

Clean tools with white spirit immediately after use before the product dries. If dried, mineral spirits or a stiff brush may be required, but prompt cleaning is most effective.
