If your natural stone surfaces will be exposed to liquids, oils, grease or other elements that can create stains, they should be sealed.
Porous surfaces – such as natural sandstone and limestone – can be easily marred by solvent contaminants that will penetrate deep into the substrate and leave them looking mottled and past their best. To keep your stone investment looking great for longer, sealing is the answer.
When should I seal my natural stone surface?
If you’re installing a new natural stone surface, you’ll want to get on to getting it sealed right away. Natural stone in commercial or residential situations need to be sealed twice – once before grouting to reduce the stone’s porosity, then after grouting to further protect it from the elements.
How much maintenance will I need to do on my sealed stone?
Stone sealants also make maintenance easier, saving you time and money. You will also need to re-apply a sealer at regular intervals – every few years – to keep the stone well coated and fully protected. If you use a coating sealer, you’ll need to remove the existing sealer completely before reapplying an impregnating or consolidating sealer.
