Types of Stone Sealer and How They Work…

By KleanSTONE | Feb 20th, 2019 | 0 Comments

If you have a natural stone floor, the chances are that you will have heard of the importance of sealing it. If not, you should definitely read; Floor Sealing: The Most Important Thing You Are Not Doing. If you are looking for a sealer for your stone floor it can be difficult to get to grips with what stone sealers are and which one to choose. There is a range of stone sealers available depending on the type of stone you have, level of cover you require and your budget.

Despite the huge range of stone sealers available, most fall into one of two categories, Penetrating and Topical.


Penetrating Stone Sealers

A penetrating stone sealer, also known as impregnators or penetrants, are just that – they penetrate the porous surface of the stone and activity ‘block’ contaminants in the form of liquids and debris from entering into it. The best penetrating stone sealers maintain the stone’s porosity and allow it to expel any water vapour once it’s been sealed – in essence, they allow the stone to remain ‘breathable’.

Penetrating stone sealers tend to be either solvent-based or water-based. This refers to the carrier which the active compounds are in solution in. The solvent or water penetrates the surface of the stone before evaporating out, leaving the active chemicals in place to protect the stone. Solvent-based stone sealers are, generally, more effective as they offer superior performance and typically last longer than water-based types. However, as these sealers are solvent-based it’s not always possible to use them (particularly in some commercial environments) and they can often have very strong smells which aren’t always ideal in the home.

Hydrophobic and Oleophobic Stone Sealers

When it comes to the properties of your penetrating stone sealer, the next consideration would be hydrophobic or oleophobic. Hydrophobic stone sealers repel only water-based liquids whereas oleophobic stone sealers repel both water and oil-based liquid contaminants. We would always recommend an oleophobic stone sealer as this ensures protection from any kind of potentially staining liquid contaminant.

Topical Stone Sealers

Topical stone sealers are sealers that sit on the surface of the stone. Topical stone sealers are sacrificial and can either strippable or permanent. Most topical stone sealers are water-based that are manufactured from polymers so that they can be removed if needed with the use of a floor stripper. Topical stone sealers are much cheaper than penetrating stone sealers.
