Thompson’s WaterSeal Multi-Surface Stain, Clear
Product overview: Thompson’s WaterSeal Clear Multi-Purpose Waterproof Stain is built to waterproof concrete, brick, and other exterior surfaces. It provides a clear finish that hides grain while preserving brick texture. The coating delivers fade resistance through advanced polymers, helping protect against UV damage across seasons.
Best for: Outdoor brick projects where you want a nearly invisible finish that still shows texture. The clear stain suits decks, masonry facades, and concrete blocks when you prefer a natural look with weatherproofing.
Why chosen: Its clear formula minimizes color change, allowing brick masonry details to remain visible. Fade resistance helps maintain appearance year-round, a practical feature for sun-exposed brick walls.
Caution: As with all clear seals, surface preparation matters—ensure brick is clean and dry before application to avoid streaking or uneven coverage.
Waterproof Sealant, 35 Oz Transparent Coating
Product overview: Velxora’s transparent waterproof sealant uses Advanced Thin-Flow Sealing Technology to spread into small cracks and gaps for even coverage. It blocks water penetration by sealing vulnerable openings and provides a clear finish that preserves original color and texture.
Best for: Indoor and outdoor brick and masonry surfaces where a continuous, light-coating barrier is desired without altering appearance. It works well on small cracks and seams often found in brick walls and planters.
Why chosen: The emphasis on small gaps and a continuous barrier helps reduce future leaks without heavy surface buildup, making it ideal for brick where texture should remain visible.
Caution: Apply in thin coats and avoid heavy buildup on porous brick to prevent run-off or uneven texture.
Hensire Transparent Waterproof Sealant 17oz
Product overview: Hensire offers a water-based, low-odor clear sealant that dries transparent to protect wood, concrete, masonry, brick, stone, tile, and grout. Suitable for indoor and outdoor use, it preserves original color and texture while forming a protective coating.
Best for: Brick and masonry projects where low odor is important, such as indoor basements or garages, plus exterior brick applications where a non-intrusive finish is preferred.
Why chosen: The low-odor, easy-cleanup formula makes it accessible for DIYers and professionals alike, especially in spaces with limited ventilation.
Caution: Not intended for metal surfaces; always test a small area to confirm finish uniformity on brick.
