Natural Stone Sealing: Understanding How To Seal Your Stone

Natural stone sealing is a seamless process that prevents staining and maintains your natural stone’s beauty. Our technicians usually recommend an inseminate sealer which penetrates deep into your natural stone’s surface to protect it against moisture, dirt, and stains. Before sealing natural stone, a thorough cleaning is recommended to avoid sealing dirt, grease, debris and other substances into the stones surface.

The life of the sealer will depend upon the type and finish of the stone, the area of application, and its exposure to wear. A piece of stone which is sealed with an inseminate  sealer and put in a closet will stay sealed indefinitely. Inseminated sealer’s are preferred to topical sealer’s because they expand both the longevity and quality of the protection.

Although sealer makes the stone less gullible to staining, applying when it when not needed, just wastes time, effort, and most importantly, money. An easy test to determine if your natural stone needs to be resealed is to sprinkle it with water. If the water rounds up tightly, then the stone has maintained its seal. If the water soaks in or darkens the natural stone, then allow the water to evaporate and reseal. Granite sealers can last up to 15 years, depending porousity and type of granite.  General suggestions for residential granite is to seal once every 5-10 years.

Prior to sealing, clean your natural stone thoroughly with warm water and a neutral ph cleaners. Let the stone dry, and then begin working in sections at a time. Apply the inseminate sealer using a clean towel, wiping on a thin coat on your natural stone evenly covering the entire surface with the sealer.

Allow the sealer to stand for approximately 3-5 minutes. Remove excess sealer by buffing with a clean dry towel. If the sealer accidentally dries on the surface, re-wet with more sealer, and wipe dry with a clean terry cloth. As you get close to completing the sealing of your natural stone, wait about 24 hours and repeat the H20 test. If the water beads up, you are finished sealing. If the water does not bead up, apply another coat of sealer.

The process of sealing stone is straight to the point and can for the most part be handled by a homeowner as part of usual home maintenance. Sealing a kitchen countertop will take about 30 minutes, but a large area of flooring can take notably more time. If you prefer, contractors and restoration companies can take care of cleaning and sealing for you. Such as our team of knowledgeable technicians! ; )
