It is also a black limestone sealant or black limestone paint that can transform the look of old, faded limestone patios. Most people who have black limestone paving laid around their properties want to keep the original, black shiny look of the black stone. However, with long-term exposure to weathering and UV light, the original black stone paving will turn a lighter grey over time. This visually unappealing problem can quickly be resolved by the application of the black patio slab sealer. The grey paving stones will quickly return to their original appearance once the black tile sealant, or what some people refer to as a black tile paint, is applied. The black patio sealer wet look is a remarkable patio colour restorer that brings old faded limestone back to its former glory. It also acts as a black grout sealer. The black limestone sealant can also be used as a sandstone sealer, as both sandstone and limestone are porous natural stone substrates. The black pigmented sealer for limestone will absorb into the surface and put the rich black colour back into the surface of the stone. If you want a wet look patio sealer for black limestone that performs really well, then SmartSeal black limestone sealer has been formulated to produce great results every time. The wet look stone sealer can help you avoid expensive replacement of a black limestone patio, by enriching the colour and protecting the surface from deterioration. Apart from the look of the patio once the black stone sealer has been applied, the limestone paving sealer will also help to inhibit the growth of mould, algae and lichens on the surface of the stone by making it waterproof. The water repellent sealer makes the surface of the limestone paving impervious to water, which in turn inhibits the growth of green algae and mould, which tend to thrive on porous substrates.

Review: Amazing product, best sealant I’ve ever bought !! - What an amazing product !! After laying black limestone and cleaning lots there remained a few pitted mortar splashes (as you’d expect) and so decided to seal with a black pigment sealant. It was an amazing result !! The sealant was easy to apply with a roller, quick to dry and apply a second (and third for good measure) coat. The results are stunning, mortar marks disappeared, water simply beads on top of the stone. I looked at the price of normal sealant versus this black pigment one and the delta was so small I decided it was worth the extra cost. It isn’t cheap but I did find it goes a long way. So I will buy again for another much older weathered patio to revive that. The reviews I read before I bought this product were right, amazing product, amazing results, what’s not to love (except maybe a little cheaper would be nice - such is life). Review: Excellent product - Excellent product- easy to use with good coverage and finish. Pity is not a Prime product with next day delivery! ## Features - Restores Colour to Faded Black Limestone Surfaces: The black limestone restorer is a colour-reviving black sealant for exterior black limestone paving. It will revive the vibrant black look of old faded black limestone that has lost colour and gone grey over time. Dull, faded and weathered black limestone can quickly be restored to the rich, deep black original colour when first laid. The black tile sealant also acts as a patio grout sealer, as it will seal and colour the grouting on the patio the same colour as the surrounding paving. - Water Repellent & Stain Resistant: After application, the black limestone sealant creates a protective barrier against rain, contaminants and watermarks that can leave unsightly stains on the surface of black limestone. The black stone patio sealer is frequently used on old black limestone patios to seal and deepen the colour. The black patio sealant will also disguise mild acid etching and other visible staining on exterior black limestone paving. - Colour Boosting Wet Look Finish: Black limestone patios look great when first laid, but will soon fade over time with constant exposure to UV light and general weathering. The colour boosting black sealant for limestone is a stone sealer that can quickly make an old, faded limestone patio look like new. The black patio slab sealer or patio sealant wet look dries to a visually appealing, rich satin finish that can transform the look of any faded grey paving on black limestone patios. - Application & Coverage: Applying the black limestone tile sealant is easy using a roller or microfibre cloth. A brush can be used to cut into areas that may be difficult to reach with the roller or cloth. Coverage of the black stone sealer averages 4-5m² per litre on the 1st coat and 6-8m² per litre on the 2nd coat. The black limestone patio sealer should be touch dry in 1-2 hours and dry enough to walk on in 4 hours. - Lasting Protection to Exterior Black Limestone: Once applied, the black limestone sealer becomes a wet look patio seal that helps protect the surface of patios, paths and drives. The black stone patio sealer is UV-resistant, which will help slow down future colour loss. The black limestone colour enhancer is also a waterproof stone sealer that helps prevent damage from water ingress and frost. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B095J159XR | | Best Sellers Rank | 5,705 in DIY & Tools ( See Top 100 in DIY & Tools ) 122 in Sealers | | Brand | SmartSeal | | Colour | Black | | Compatible Material | Black Limestone, Limestone, Slate | | Customer Reviews | 4.4 out of 5 stars 342 Reviews | | Included Components | Product Only | | Item Form | Liquid | | Item Weight | 5 Kilograms | | Item form | Liquid | | Item weight | 5 Kilograms | | Manufacturer | Smartseal UK Ltd | | Manufacturer Part Number | BLK-LIME-5 | | Material | Acrylic | | Number of Items | 1 | | Style | 5L | | Style Name | 5L | | Surface Recommendation | Black Limestone | | Unit Count | 5000.0 millilitre | | Water Resistance Level | Water Resistant | | Water resistance level | Water Resistant | ## Images ![SmartSeal Black Limestone Sealer - 5L - Easy to Apply Black Limestone Patio Sealer.

Pity is not a Prime product with next day delivery! ### ⭐⭐⭐⭐ Makes your patio look great every couple of years. *by I***M on 16 March 2026* I'm well placed to review this product now, I initially bought it three years ago based on the reviews here. Its really good as turning the Limestone back to absolute black. Its really easy and quick to apply and dries pretty quickly too. It will splatter a bit if you're not careful but it really looks great after its applied. However, you will probably find you need to re-apply it after 2 years. I've just re-applied it as it had worn off. I think if you consider this to be something you'll do bi-annually then this is a great product. It won't however permanently fix the colour. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/322656661-smartseal-black-limestone-sealer-5l-easy-to-apply-black-limestone](https://www.desertcart.us/products/322656661-smartseal-black-limestone-sealer-5l-easy-to-apply-black-limestone) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-06-08*
