Top 3 misconceptions about natural stone and sealing
We here at Surfacepedia like to think we know a little bit about stone. But not everyone is a stone expert – if you’re an ordinary home owner, you’ve probably got a million things to think about that trump the basics of natural stone care and maintenance.
It’s true: Most people, don’t know all that much about stone or surface protection. And while this is not unusual, the unfortunate consequence of this is that there are numerous misconceptions floating around about natural stone.
Allow us this opportunity to bust a few of these more widespread myths.
Stones don’t require maintenance
If nothing else, stones are known for being tough. Rock is colloquially understood to beat scissors, rock music tends to be loud and heavy, and when something is particularly resilient, we refer to it as “rock hard”.
Unsurprisingly then, many people think they can simply install their natural stone feature, wipe their hands and walk away. But in fact, stone is a very porous material, and able to absorb various damaging substances quickly. According to a research paper form the University of Alicante in Spain, stones like sandstone, travertine and limestone are all considered especially porous stones, with a porosity level of around 10 per cent.
That’s why all stones need to be sealed with an impregnating sealer, like Dry-Treat’s STAIN-PROOF Original™. They will prevent moisture and other substances from reaching into the surface.
Stone sealers can prevent against acid damage
There’s plenty that sealers can do in order to keep your stone free of issues like freeze-thaw spalling or picture framing. Protecting it from acid etching, however, is a different story.
With acid sensitive stones such as travertine, marble or onyx, any acidic liquid which touches the surface will leave unsightly etch marks in your stone that will need to be either repaired or, at worst, be removed by replacing the stone.
Unfortunately, impregnating sealers won’t be able to stop the acid liquid – whether it’s vinegar, lemon or even acid rain – from touching the surface and wreaking havoc on your stone. The most you can do is keep these substances away from the stone or clean out the resulting stain.
Anyone can seal a stone
Many sealers, including products like Dry-Treat’s META CRÈME™, are easily available either online or in brick-and-mortar stores, and there’s technically nothing stopping you from applying them yourself. However, just because you can, doesn’t mean you should.
To do the job properly, you really need the hand of a professional who knows how and where to apply it, along with the various tricks and techniques to making it successful. To have a long-term working result, it needs to be applied correctly. That’s why many Dry-Treat products come with many years-long warranties if applied by an Accredited Applicator.
