Topical vs Penetrating?

August 22, 2021



There are a variety of sealers to choose from but in general they fall into two categories: topical and penetrating. Which is best for you?
* Sits on the surface, preventing liquids and foods from sinking into the stone.
* Suggested for extremely porous stones like limestone or sandstone
* Gives a glossy appearance but also darkens the color of the stone.
* Prevents scratching/etching although the topical sealer itself can be scratched and the only way to fix it by re-sealing.
* Doesn’t breathe – it can trap moisture inside
* Wears away with use. May need to be reapplied every year.
Penetrating Sealers / also known as impregnating sealers
* Is absorbed below the surface of the stone, filling the pores
* Prevents liquid absorption into the stone
* Doesn’t affect the color of the stone after it’s cured
* Does not protect from scratches on surface
* Allows the stone to breathe – because it does not trap moisture it is preventing possibility of mold inside the stone
* Lasts for years and doesn’t need to be re-applied frequently.
We recommend a sealer that is designed to last and comes with a 25-year warranty when applied by one of our accredited applicators. For more information and to get a quote, give us a call and if you have the measurements of the countertops you need sealed we can give you an immediate quote.
