Black Limestone Restorer

£6.99£229.00

Black Limestone Restorer is a high-performance black limestone paving sealer & colour restorer. This black limestone sealer & restorer has been specifically formulated for sealing and enhancing the colour of black limestone patios, pavers & slabs. Black Limestone Restorer will deepen surface colours enriching its appearance, a little like dampening with water.

Black Limestone Restorer can be applied to both external and internal surfaces. One single application is sufficient to seal and enhance most surfaces. This black limestone sealer will dry to a natural, matt & breathable colour enhanced finish.

Black Limestone Restorer can be applied to newly laid pavers or existing surfaces which may have faded. A small amount of product goes a long way. One application is all that is required to resist oil & water-based staining and deepen colour.

This product is not a topical sealer which, when dry, forms a lacquer or skin. The limestone will retain its natural matt appearance. Black Limestone Restorer penetrates the surface sealing and colour enhancing from within.

Black Limestone Restorer will not peel, crack, flake or trap moisture. This breathable limestone sealer can be applied as an initial sealer soon after installation, or seal & restore colour to older faded slabs. This sealer can also rectify mild acid damage – please contact us for guidance.

Available in 1 litre or 1 litre bundle deals, with free standard delivery. Samples are also available to purchase.

Product Details

The ultimate black limestone enhancing sealer

Black Limestone Restorer seals & strongly enhances surface colours to all black & grey limestones. This limestone sealer & restorer will enrich the colour of your black limestone pavers, deepening colour, and restoring faded surfaces. Black Limestone Restorer can be used to seal & colour enhance newly laid pavers & tiles. It will also seal and revive older fading or weather worn black limestones. Black Limestone Restorer resists water & oil-based staining and also colour enhances the stone. Black limestone pavers will seem ‘blacker’ after the application of this product. Floorseal Black Limestone Restorer does not contain a pigment, it is a clear liquid which penetrates the stone altering the colour making the surface darker. This limestone sealer will dry to a matt, natural but enhanced appearance. It is not a non breathable surface coating that periodically requires stripping and resealing. Black Limestone Restorer is a powerful sealer and colour restorer which only requires a single application.

Before sealing it is important that your pavers or tiles are clear of grout, brush in compounds or sand & cement mortars. Obvious dirt, dust and surface contaminants should be removed. For external limestone we recommend pre-cleaning with Floorseal Sealer Residue Remover, particularly if you have used a brush in compound. The residue remover will break down the invisible resinous slick left either side of the joint. Sealer Residue Remover will also remove general grime, oils and dirt. It is important that the limestone is totally clean and porous before applying the sealer. Interior floors can be cleaned with Floorseal Stone Floor Cleaner. It is a non-acidic deep cleaning solution for the removal of dirt, grime, oils and waxes. Ensure the limestone is totally dry before any sealing work takes place. We would recommend 24 – 48 hours drying time before sealing.

Black Limestone Restorer sealer will revive limestone that has faded to a dull finish

Black limestone naturally fades from darker to lighter shades, this fading can become obvious even during the course of the installation. It is due to a variety of factors some chemical, and some from wear and abrasion. Wear or abrasion makes the surface of a soft stone, like limestone, appear washed out and faded. Wear on darker limestones manifests itself as a lightening of colour, which can be corrected. As limestone is an acid sensitive stone, even rainwater causes the stone to lighten over a relatively short period of time. The limestone becomes slightly etched as rainwater dissolves the surface, this etching process is a roughening of the stone. You will notice this roughness as a lightening of colour, even if you cannot obviously see it. Floorseal Black Limestone Restorer helps to deepen colour, reversing the natural fading associated with this stone. When pre-cleaning black limestone it is important not to use an acid wash to remove cement residues. If you have already accidentally acid damaged a black limestone we recommend you call us before attempting other sealing or colour restoration treatments. Black Limestone Restorer will restore light acid etching, it is always prudent to carry out a test on a single slab or tile first. This will give an indication of the depth of colour that can be acheived. When installing black limestone the level of care the installer takes is crucial. Joints must be pointed neatly (or grouted) as mistakes can be difficult to correct. Excess jointing compounds may weather off over time but it is better not to have an excess at all! Remember that this is a soft stone which cannot be cleaned with an acid to remove grout or cement staining. Never use an acid to clean black limestone as it will etch the stone!! All black or grey limestones benefit from sealing and the deepening of surface colour. As a rule the deeper the colour of the limestone the more attractive black limestone looks. It is worth noting that, at best, black limestone is really an anthracite colour. Sometimes it is clearly a mid-grey, so are never actually a true black and all lighten in colour quite quickly. Floorseal Black Limestone Restorer seals and improves colour. On exterior surfaces sealing will also inhibit the growth of moss, algae and lichens. The sealer acts as a barrier to prevent general water & oil-based staining on both interior and exterior surfaces. This product does not produce an unnatural shine or gloss finish. It is purely designed to enhance colour and retain the natural appearance of black or grey limestone. This black limestone sealer & restorer covers approximately 25m2 per litre. This sealer only needs to be applied in one single application.

Frequently Asked Questions

Does Black Limestone Restorer contain a pigment?

No, it is a clear liquid that penetrates the surface and deepens the colour from within, a little like oiling wood.

Do I need another product to seal the surface after using Black Limestone Restorer?

No, this product both seals against oil and water-based staining and also deepens colour. You do not need an additional sealant – Black Limestone Restorer seals and colour enhances all in one.

How does Black Limestone Restorer work?

It soaks into the limestone to deepen its colour. It is also a waterproofing agent so inhibits water and oil-based staining.

A little like oiling wood, when applied to grey or black limestone it simply deepens the shade of the stone.

This sealer only requires one application, the product is meshed into the surface of the stone rather than drying on the surface like a lacquer or ‘coat’.

Does this product create gloss, sheen or shine?

Black Limestone Restorer will always dry to a natural matt finish as it is primarily an impregnator. The product penetrates the surface of the limestone to seal and deepen colour from within. Therefore does not create a sheen or surface coating which is subject to cracking, abrasion, peeling, flaking or wear patterns.

Do I need to pre clean my black limestone paving before sealing?

We recommend pre-cleaning the surface with Floorseal Sealer Residue Remover if you have used a brush in compound. This is to remove the resinous slick that can be present around the joint.

Never clean and seal on the same day – wait at least 24 hours – preferably more.

For internal floors pre-clean with Floorseal Stone Floor Cleaner.

I have cement staining to my black limestone, how do I remove it?

With care! – do not use an acid! Soaking with water with long dwell times can help.

If it is just a residue very carefully pressure washing may work. Do not hold the nozzle too close to the surface of the limestone or you will mark it!

Using our non-acidic Floorseal Sealer Residue Remover can help if it is a light contamination.

 

Can I use an acidic cleaner on my black limestone?

No, limestones are all acid sensitive and you will etch the surface! Under no circumstances use an acid on a limestone or any kind.

I have accidentally cleaned my black limestone patio with acid what do I do?

Ring us! The level of damage the acid has created will dictate the level of success when using Floorseal Black Limestone Restorer.

Try a sample before you buy!

Can I use this sealer on an internal floor?

Yes, this product is suitable for using on internal floors.

What is the best way to apply this product?

Apply in a single application, working in small sections of a few pavers wide or deep.

Remove all excess before it dries, typically no more than 20 minutes. It is imperative that all slabs are buffed dry with microfibre cloths. Do not apply if rain is likely in the next 24 hours. A microfibre mop, microfibre cloth or paint pad can be used to apply the product.

Removing the excess is crucial but is easy to do when working in small patches.

Can I seal a newly laid patio with Floorseal Black Limestone Restorer?

Yes, it will seal and deepen the colour of your newly laid pavers.

Why does black limestone fade?

It is a soft acid sensitive surface – if it wears by abrasion or by being dissolved by rainwater it becomes lighter in colour.

A strong colour enhancer will darken the colour and seal it.
