The LTP Blackstone Sealer & Restorer is a water-based impregnating sealer designed to restore the appearance of faded dark stone surfaces while also providing protective treatment. Ideal for reviving tired-looking exterior stone, it helps bring back depth of colour to dark natural and artificial materials while supporting longer-lasting surface protection.
Formulated specifically for faded dark stone, LTP Blackstone Sealer & Restorer is suitable for a wide range of materials including limestone, marble, slate and concrete pavers. This makes it particularly useful for exterior areas where darker stone finishes can lose their richness over time through weathering and exposure. Rather than simply coating the surface, it works as an impregnating sealer, helping enhance the appearance of the material while also treating it more effectively.
Because it is water-based, the product offers a practical way to restore and protect stone without relying on a heavier solvent-style treatment. Its main role is to help recover the look of worn or weathered dark surfaces, making it especially relevant for outdoor stone features where appearance has dulled and colour needs reviving.
Suitable for exterior use, it is a strong option for darker paving, masonry and outdoor stonework that needs both visual restoration and surface protection. Available in 250ml, 1 litre and 5 litre sizes, it can suit smaller spot-treatment jobs as well as larger exterior stone restoration projects.
