Should You Seal Your Stone Veneer?

You have recently decided to improve the appearance of your home by adding stone veneer. You have decided after some research that you would like to seal and possibly enhance your new manufactured stone but you’re not sure where to begin. Fortunately, North Star Stone is here to help. Continue reading to learn a bit more about stone sealers and enhancers.

What is a stone sealant?

Sealant is a product that is typically brushed over stone in order to provide a protective layer against things such as salt, weather, moisture, stains and potential color deterioration. There are several brands on the market that can be purchased at retail stores like Home Depot and Lowes as well as on the web. It is recommended that you avoid products with acid and use a silane or siloxane-based sealant that is penetrating yet provides breathability. Eagle Natural Seal or The Armor SX5000 WB are two brands available at Home Depot. At Lowes you can find Eco Advance Concrete/Masonry Siloxane Waterproofer.

What is a sealer + enhancer?

Like the name implies, a sealer + enhancer does the job of sealing as well as enhancing the stone, which essentially means it works to bring out the natural character of the stone and to essentially make it more vibrant. It is important to make sure when selecting a sealer + enhancer that it is safe to use on manufactured or man made stone such as stone veneer. Just like with sealer, it is always a good idea to do a spot check in an inconspicuous place to see how your stone reacts with the product. 511 Seal & Enhance by Miracle Sealants is safe to use on manufactured stone and can be found at Home Depot.

Why should I use this product?

The general rule where sealing stone veneer is concerned is, if the stone darkens when a drop of water hits it then it can also be stained by other materials in the environment like oil, dirt or plant residue. Furthermore, the up side to sealing your stone is that it makes stone veneer even more easier to clean and will provide protection against the environment and color fading. Additionally, depending on the weather conditions and climate where you live, in order to protect your stone’s appearance and longevity, the relatively short time it will take you to seal your stone is well worth it. As a result, applying a sealant to your stone is most likely a good idea to prevent the need for repairs. Many stone veneer manufacturers will often say their stone does not require sealing, which essentially leaves the choice with you. Most sealers can be applied to stone on the interior and exterior of your home, so keep that in mind for any stonework beautifying the inside of your home as well.

Things to Know about sealers

  • Certain sealers may make your stone appear wet, slightly darker and or vibrant.
  • Always test a small portion of your stone with the sealer or sealer + enhancer product first in an inconspicuous place before applying it all over. This will help you know how your stone will respond to the product.
  • The more porous the stone the more coats required. Read instructions carefully.
  • Check with your stone veneer supplier to make sure the product you purchase is safe to use on your stone.
  • Sealing or enhancing your stone is something you will need to repeat periodically. Check your product information for details.
  • Make sure you are applying your product under the right weather conditions, as it may not perform correctly.
