beauty. With a few simple steps of care and maintenance, you can preserve that beauty in your natural stone.

Stone Care Q&A

Does Natural stone require sealing?

All natural stone should be sealed. We recommend Stain Proof ™ (applied in 2 coats). Stain Proof sealers penetrate deep into the stone, allowing stains to be removed much more easily than with other sealers.

How often do you need to re-apply sealer?

Unlike other sealers, with Stain Proof ™, re-sealing is not normally required.

Samples of stones are not usually sealed, will they show stains immediately if tested?

Natural stone should be sealed prior to using. Testing, if required, should be done by sealing sample first with Stain Proof™ with the correct procedure. Allow 21 days and then test sample. Samples handed out to customers are usually not sealed.

What different types of sealers are available for sealing natural stones?

A physical coating placed on the surface of the stone. Not recommended as it changes colour, scratches and damages over time. Impregnating sealer…Absorbed into the stone. This allows the stones to breathe, allowing moisture to evaporate.

How is it possible to tell if a stone has been sealed or requires re-sealing?

When the water does not bead (sit) on the surface of the stone and also when it absorbs immediately and leaves a darker wet area.

Can sealing be done by anyone?

Yes. You can apply sealer yourself, or you can use an approved Dry-Treat applicator. An accredited applicator is able to provide a 15 year written warranty from Stain Proof™.

Can Dry Treat be applied over other sealers?

Dry-treat can be applied on most jobs that have been sealed with an impregnating sealer. It is recommended to check with Stain Proof™ and if possible tell them the name of the sealer previously used. Check which sealer was used with your stonemason or kitchen company. 

Is there a need to seal the back of tiles?

In most circumstances no. It is recommended when laying moisture sensitive tiles in a shower recess or shower wall to have them sealed on the back i.e. Carrara, Calacatta, etc. 

Are tiles sealed before grouting or after grouting?

For more porous tiles it is recommended to seal the tiles prior to grouting once and then the second coat after grouting. Does sealing affect the look and slipperiness of the tiles? With  Stain Proof™, it does not affect either. 

Can the sealer wear away or be affected or removed by using chemicals? What is the maintenance that is required?

Stain Proof advises that there is no product that will remove Stain Proof ™ from the stone, which actually penetrates 6- 10mm depending on the stone. Stone sealed with Dry Treat does not require special maintenance. Spills should be wiped up immediately and cleaning done with a clean damp cloth. For stubborn stains, a mild bleach solution may be used. 

Do sealers protect the stones from acids in foods and liquids?

Most Granites are unaffected by acids used in the kitchen, but Marble, Dolomite, Limestone, Travertine, Sandstone and some Quartzite have Calcium Carbonate in the stones. Calcium reacts with acid and causes a dull spot on the surface (etching), which is why we recommend these stones finished with a honed surface if required in a kitchen.
