Stone Sealers & Cleaners

We can help you protect your natural stone from staining and deterioration...

Reasons to seal natural stone

Building materials such as natural stone, tile, masonry, concrete and grout are all made up of countless invisible capillary pores. This makes them porous and allows the absorption of damaging liquids such as water, water-borne salts and oils.

These liquids cause the building material to deteriorate prematurely and in doing so, reduces their usefulness. Examples of deterioration include weathering, loss of strength, efflorescence, salt attack, freeze-thaw spalling, sulphate attack, alkali aggregrate reaction, unsightly staining, biological attack, steel reinforcement rusting, chemical attack, swelling, thermal conductivity, embrittlement and picture framing. Sealing can eliminate or significantly reduce most of these problems.

What type of sealer should you use

There are two main types of sealers, namely, surface sealers and impregnating sealers. A surface sealer will provide a physical barrier over the surface, the result is a darkening of the surface. These coatings usually wear and weather relatively quickly, make the surface more slippery when wet and must be completely stripped off when re-coating. Salts may also build-up under the surface, causing the coating to appear cloudy.

Impregnating sealers can be classified as those that repel water and those that repel both water and oil based stains. Impregnating sealers usually have little effect on the frictional properties and appearance of the surface but will not completely stop dirt and rubber getting into the open pores of the surface.

When comparing similar sounding impregnating sealers the two most important questions are: (a) is it permanent? and (b) how deep does it penetrate below the surface? A good depth of penetration is critical to provide protection against traffic wear and weathering.

We also carry out the smaller works, cleaning and sealing a natural stone patio, or even natural stone floors internally in some ones house.

Dry treat can also be used to seal concrete such as reinforced concrete structures like bridges and building facades. Sealing concrete in coastal location is especially important due to risk of salt attack & freeze thaw action.


Where can I buy stone sealing & stone cleaning products?

Everything Stone is a dealer & approved applicator, so you can come into the showroom or contact a member of staff to discuss what type of sealer or cleaner suits your requirements.

Can someone supply and apply your products for me?

Yes. Everything Stone offers a full application service for large projects such as sealing walls on an entire building, or sealing paving in a town centre to smaller jobs such as cleaning and sealing a small patio or even cleaning and sealing a stone floor inside a house.

Can I apply the sealer myself?

Yes, sealers are easy to apply, usually by following instructions on the bottle.

Will the sealer change the appearance of my stone?

It may, so always carry out a test in a non-conspicuous place first and wait 24 hours to see the results.

How to maintain a sealed stone countertop

The kitchen is dirtier than most bathrooms. A kitchen worktop has about 10 times more bacteria than a toilet seat! Near the drain there are about 3,000 bacterial per sq.cm. Without nutrients and water, bacterial cannot grow. This doesn't mean that the surface won't get dirty after it has been sealed, but it should stop water and oil based liquids from penetrating into the pores and causing a permanent stain, and should also make the countertop easier to clean.

Do I need to pre-seal my tile?

Pre-sealing is the process of sealing a tile or stone before it is installed and helps protect the tile from installation water damage such as that caused by grouting between the tile joints. One other important benefit of pre-sealing is to reduce the effects of grout migrating into the side of the tile causing an unsightly discolouration. Always ask the supplier of your sealer about the issues relating to bonding once you have pre-sealed your tile, you must make sure that you are using a suitable adhesive.

How do I maintain a sealed tile?

The long-term good looks of a sealed surface will depend on maintenance. Removing spills immediately, using diluted bleach to remove marks and routine cleaning and scrubbing of the surface will keep surfaces looking good for longer. We supply a range of products to assist with daily cleaning and/or more intensive spring cleaning.

What is 'picture framing'?

This is a term used to describe a discolouration that may occur to the outer rim of the surface of the tile. The source is usually either the seepage of grout into the tile or, for cement based materials, an uneven curing of the cement in the tile or, water. Picture framing is usually irreversible and it is best to prevent it from occurring. Preventive measures include pre-sealing the upper-surface of the sides of the tile.

Will I still get some staining after sealing?

All sealers have their limits. For instance they will not stop surface etching, so to minimize absorption the spill should be cleaned up immediately. We recommend that you clean up spills as soon as it is possible and clean regularly using hte right product.

What do I do if there is already a sealer on the surface I want to treat?

Usually pre-existing surface sealers must be removed. There are different products on the market depending on the stone type, please request further information. Use plenty of dry white cloth when removing the old surface sealer, this is particularly important with polished porcelain tiles which often arrive with a factory applied wax coating. Make sure you do a test area first.

I have sealed my surface with a impregnating sealer. Can I apply a surface sealer over the treated surface?

Yes, but you will need to wash the surface with solvent such as methylated spirits or better still acetone and use a solvent-based surface sealer. The reason for this is because only a solvent-based surface sealer will adhere to an impregnated surface.

How old does cement based grout need to be before sealing?

The grout needs a minimum of 3 days to cure before sealing.

How do I know if my surface is still adequately sealed?

Please carry out the following water test; place a tablespoon of water on the treated surface for 20 minutes, blot up the water with a tissue, pressing hard to soak up any water in the texture of the surface. If the water is absorbed or leaves a dark mark the surface needs more sealing.

Will sealing stop the growth of moss and mold on my concrete?

Moss and mold will even grow on glass under the right environmental conditions. However, moss and mold need water to survive and sealing the surface with will significantly reduce the amount of water available and so greatly reduce the growth of algae and the like.

Why is my outside limestone patio still fading even though I have sealed the surface?

Pure water has a pH of 7.0. However, normal rain is slightly acidic because carbon dioxide (CO2) dissolves into it forming weak carbonic acid, giving the resulting acidic mixture a pH of approximately 4.3 to 5.6 at typical atmospheric concentrations of CO2. Limestone is sensitive to acidic liquids and when used outside will etch causing surface roughness and giving the appearance of fading. Impregnating sealers can reduce but not stop
