This 5L bottle of Thompsons Water Seal Exterior Waterproofing is designed for homeowners and property managers seeking robust protection against harsh weather for brick, concrete, and stone surfaces. Its key benefit is providing deep, structural defense against water damage, frost, and erosion, ensuring long-lasting preservation. A potential caveat is that it's formulated for dry, porous surfaces, so preparation is key. The product offers advanced hydrophobic technology, deep penetration, breathable protection, and UV resistance to maintain the original appearance of your property.

The protection is designed to last for several years, depending on environmental conditions and surface wear. While initial water beading may fade, the internal protection remains. Reapplication is recommended when water no longer beads effectively.
No, Thompsons Water Seal is designed for porous surfaces. Applying it over non-porous materials like paint or existing sealants will prevent proper adhesion and penetration, rendering it ineffective. Always test in a small, inconspicuous area first if unsure.
Coverage varies greatly depending on the porosity and texture of the surface. As a general guideline, a 5L container can cover approximately 5-10 square meters per liter for heavily porous surfaces, and up to 20 square meters per liter for less porous ones. Always refer to the product label for specific guidance.
No, Thompsons Water Seal dries to an invisible finish, preserving the original texture and color of brick, stone, and concrete.
While the product is designed for exterior use, it is advisable to protect nearby plants and water features during application. Cover them to prevent direct contact. Once dry, it poses no environmental hazard.
The best time to apply is when temperatures are between 5°C and 25°C, and the forecast predicts dry weather for at least 24-48 hours after application. Avoid applying in freezing conditions or when rain is imminent.
This can happen if the surface was not porous enough, or if the product has fully penetrated. The protection is still active, though the visual cue of beading may fade over time. Reapplication might be considered after several years.
While designed to dry clear, some porous materials may darken slightly. Ensure the product was applied evenly and allowed to dry completely. Test in an inconspicuous area first if concerned about color change.
The surface may be too wet, not porous enough, or already sealed. Ensure the surface is dry and assessed for porosity before application. Consider a test patch.
This often results from inconsistent application. Ensure even coverage with a brush, roller, or sprayer. Avoid applying too thickly in some areas and too thinly in others.
Preparation: Ensure the surface is clean, dry, and free from dirt, mold, or loose debris. For best results, treat surfaces when temperatures are above 5°C and rising, and when no rain is expected for at least 24 hours. Avoid applying to saturated surfaces or during very humid conditions.
Compatibility: Suitable for use on porous materials including brickwork and masonry, concrete paths and drives, porous stone, flagstones, and rendered walls. Do not apply to non-porous or previously sealed surfaces without testing compatibility in an inconspicuous area.
Application: Apply liberally using a brush, roller, or low-pressure sprayer. Ensure even coverage. For very porous surfaces, a second coat may be applied after allowing the first coat to dry.
Care: Once applied and dried, the barrier is largely maintenance-free. Periodically check treated areas for signs of wear or reduced water repellency, typically after several years, and reapply if necessary.
