Sealing natural stone

Countertops, especially in kitchens, have to withstand hot items being placed on them and any spills. If countertops are not appropriately protected, warm temperatures and spills can damage the surface of the natural stone. 

One way that homeowners and business owners can protect their countertops is by sealing them. A seal on your natural stone can prevent liquids from seeping into your stone and causing stains or cracks.

Not only does a sealant protect the countertop, but it also makes it easier to clean. Thus, it is recommended to seal natural stone countertops to shield them from household and business activities that can cause wear and tear.

What type of natural stone needs to be sealed?

Before sealing your natural stone countertop, it is essential to determine the type of stone as some react differently to different seals. For instance, some granite countertops do not absorb sealants leaving behind a streaky, hazy mess. 

If you use travertine, limestone and marble countertops, consider sealing them since they are soft stones that are more prone to staining and scratches. You can also seal your soapstone counters since they can quickly get superficial scratches.

Another thing to keep in mind is where you are going to use natural stone. Bathroom and outdoor spaces with natural stone should get sealed more frequently because they are prone to more water damage. 

How often should you be sealing natural stone? 

The frequency of sealing your natural stone countertop depends on how porous the stone is. For example, a non-porous stone like granite does not require sealing more than once since it has fewer channels for air and absorption. Marble countertops and limestone surfaces are more porous, requiring resealing more frequently. 

How to know whether your countertops need to be sealed?

Homeowners can check to see if their countertops are in need to be re-sealed by a simple water test. This only requires you to pour a small amount of water onto your countertop surface. Then, you should let the water sit for about 30 minutes. If you notice that your countertops are becoming darker, it’s a good indicator that adding sealant to the surface may be necessary! 

Natural stone countertops like serpentine marble countertops require some care and maintenance such as sealant to ensure they are looking and performing their best. Keep these tips in mind when deciding whether or not to re-seal your natural stone countertops.
