Black Limestone Sealer - Re- Colours and Seals
Easy to Apply, Hardwearing Solvent-Based Sealer and Colourant
Smartseal black limestone sealer is a highly-effective solvent-based sealer and re-colourant for black limestone which gives a transformative effect.
Limestone slabs will often fade over time and gradually turn a lighter shade of grey. The black limestone sealer can transform the look of faded limestone patios and make them look like they were recently laid. The sealer can be re-applied at any time to ensure any limestone slabs on patios or other external surfaces look good at all times.
Preparation:
- Clean surface using a pressure washer and/or Patio Clean Xtreme.
- Allow to dry for a minimum of 72 hours
- Apply above 12°C with a temperature no higher than 23°C
- Two coats are recommended
- Apply by roller
- Coverage: Average coverage approx. 4 - 5m²/litre first coat (dependant on surface) and approx. 6 - 8m²/litre second coat
Always apply to a test area first to determine suitability. A sample size (150 ml) is available for purchase should you wish to try it before committing to purchase 5 Litres.
***PLEASE NOTE*** - For best results, if a sweep-in jointing compound has been used when the slabs were laid, we would recommend using the residue remover prior to application.
Q: How do I clean the roller after applying the Black Limestone Sealer?
A: The tools cleaning fluid should be used to clean off any residue from the Black Limestone Sealer after application.
Q: One more question, once it has been double coated, if it's pressure washed again after a few months, is the paint going to come off? Thank you
A: Using a domestic pressure washer should not have any detrimental effect on the Black Limestone Sealer once it has been applied and has fully cured.
Q: Hello, do you need to dilute this or apply as it comes out of the can with a brush and/or a roller? Thank you
A: You do not dilute the Black Limestone Sealer. It should be applied straight from the tin without dilution.
Our driveway had extensive damage to a container of bitumen dropping on it and a large area eventually turning white, despite the bitumen being washed of quickly. I didn't really have much hope but I am amazed the this product has lifted the whiteness and restored the colour in minutes. Very easy to use. I'm now going to try and patch up a lot of patches of deteriorated concrete and I'm quite hopefully the product for that will do the job. Excellent product!!
You get what you pay for. It works, the black limestone sealer works very well and I would recommend this product 100%
I had a question for Smartseal technical team, and as always they responded efficiently. It was George from the team who helped with a complex question regarding products I can use on Black limestone, which was already protected with Smartseal for black limestone sealant. Which looks fantastic!! I needed to further stabilise the jointing compound. George's response:- "Thanks for the message. The black limestone sealer would be fine for these compounds. Usually, to help solidify it as much as possible 2 coats on the compound is best. If you did do a further application I would focus just on the pointing rather than adding an additional coat on the limestone itself as you dont want too much on the surface as it can start to have adhering problems. I hope this helps!" It's also Thankyou George and Smartseal
