Natural stone is one of the oldest, and certainly the most time-tested, of building materials known to man. Its beauty, durability, long life cycle and low-maintenance qualities make it the choice of many architects for commercial and institutional applications. Now, homeowners are also seeking the same functions in new residences and remodels. With a wider consumer base than ever, there are some simple, yet important, tips to know when using natural stone when it comes to proper care and maintenance. This article will focus on the importance of sealing to protect natural stone and the often overlooked role that a proper maintenance program plays in the ultimate success of residential stone installations.
When determining where to start, the question of “Do all natural stones need to be sealed?” must be answered. While all natural stone is porous to one extent or another, the honest answer here is no. We should take into consideration the answers to several key questions in determining the need to seal. Where is the stone being installed? Will it be installed on a kitchen countertop, a lobby floor in a condo tower, a backyard patio or in a shower? Depending on the type of stone and the area, the need or benefit to sealing can vary, as can the maintenance products and program needed. These variables, plus the owners’ expectations, need to be discussed at the very start of the project. This will ensure that all parties are in agreement and that performance and expectations are aligned.
