Why You Should Seal Your Stone

“Why should I seal my natural stone?”

  • Any spilled liquids will be absorbed and in some cases, a stain will be present
  • Natural Stone needs to have adequate protection because of its porous surface.

That’s why you need to always seal your stone after a floor installation or floor restoration. We believe that all stone surfaces should be sealed in order to protect them and in some cases enhance their natural beauty.

Keep in mind that your sealer will wear out over time and daily use. Certain cleaning products or the inevitable spill of acidic products such as wine or coffee will strip the sealer. As the sealer is stripped noticeable spottiness and dulling will occur leaving the stone susceptible to staining.

Types of Sealers

We have experience in recommending the correct type of sealer required for the stone, based on usage, likely spillage risks, environmental factors, health and safety requirements (if installed in a commercial environment), and your budget.

Have an Adequate Number of Coats Been Applied?

Because all natural stones have varying levels of porosity it is extremely important that an adequate number of coats are applied. We carry out tests after every coat to ensure that full protection has been given and the stone’s porosity has been eliminated as much as possible. As professionals, we have the experience and confidence to give natural stone the best possible protection based on a thorough application of the product. One coat is hardly ever thorough enough!

Has the stone been left with the correct finish?

A stone seal can leave two possible finishes, enhanced or natural. An enhancing sealer will intensify the colors in the stone and increase their vibrancy. There are variations of these such as an “antique finish” or “wet look”, however, they are all essentially different brand descriptions of the same type of product.

We always seal a sample prior to full application of these sealers as the finish can vary with different types and colors of stone. This ensures that our clients are always happy with the end result. An impregnating sealer, on the other hand, is one that leaves an invisible finish. These sealers should not visibly alter the appearance of the stone if they are applied properly.
