Flagstone & Natural Stone Sealant

Testimonial
“I want everyone to know how amazing Seal Southwest's flagstone sealer works. We had switched to a salt water pool and it started destroying our flagstone after about one year. After Seal Southwest's treatment we have not had any issues with our flagstone flaking and its been over 4 years. It was an excellent investment and I would recommend their treatment to anyone.”

Flagstone Surface Consolidator*
Provides long-lasting protection, prevents spalling / flaking & reduces maintenance!
Seal Southwest’s “Top Coat” sealant is non film-forming; able to consolidate loose and friable surfaces; able to work without changing the appearance of the surface - keeps the original look; suitable for indoor and outdoor use; able to greatly reduce water uptake and minimise moss growth, freeze thaw spalling and efflorescence; an excellent chloride ion salt screen - ideal for marine and pool areas; highly water vapour permeable - able to breathe so there is no build-up of subsurface moisture, allowing it to dry out; deeply penetrating - protecting against weathering and wearing; very alkali resistant - won't breakdown in contact with cement based materials, and able to seal hairline cracks up to 0.3 mm and does not flake or peel. It’s the perfect solution for preservation of flagstone, slate, engineering concrete, terracotta tile, cast stone, paving, sandstone, limestone, brick, etc.
Top Coat carries a 10-year product guarantee on horizontal surfaces—15 years if on vertical surfaces.
