What to Consider When Choosing the Best Stone Sealers
Not all stone sealers are the same! There are a few key factors you should be aware of when choosing the best stone sealer for your specific needs. Let’s take a look.
Surface Area Coverage
The first thing to check on the instruction is the proximity of surface area coverage for a stone sealer product. This will help you determine the quantity you need for the process. Usually, sealers have about 800 square per gallon surface coverage, but this might vary depending on the brand and stone material. Other reasons not to neglect these first steps are;
- Cost efficiency: Overestimating the quantity of the sealer you need will make you waste money. On the contrary, getting less product than you actually need will compromise the quality of the work, and you might have to repeat the process all over again.
- Application consistency: Calculating the right amount of sealer for proper surface coverage it’s crucial for the process. This way, you can apply the sealer consistently for a finished uniform look.
- Ease of application: Making an informed decision when picking up the product will make the whole process easier, faster, and more convenient.
Lifespan
Stone sealers have a lifespan of their own, and even the best of them will wear off with time. The typical duration for marble sealers is five years indoors and three years outdoors. The longevity of sealers depends on various factors, such as the type of the product itself, the type of stone, how much it is used, and maintenance practices.
Stone Surfaces
When choosing the best sealer for stone, you should always consider the specifics of the surface you are working with. The composition of the material highly depends on the stone type, its characteristics, and its needs.
Granite needs surface sealers that create a protective layer at the surface and enhance the stone’s durability and make it more resistant to all kinds of stains. Usually, after the finished process, this type of sealer leaves a glossy or matte finish, depending on the product and brand you choose. When working with dark-colored granite, you will need a color-enhancing sealer. It has the same protective effect while it also enhances the color of the stone.
Marble needs penetrating sealers that can reach deep into the pores of this type of stone, to create a protective barrier without altering the appearance. Marble is one of the most porous stones in the market, and as a result, it’s prone to watermarks, stains, discoloration, etc. Other types of common stones that are suitable for penetrating sealers are travertine, limestone, sandstone, slate, terracotta, etc.
Flagstone needs enhancing sealer, which is arguably the best natural stone sealer. Not only it protects the stone from stains and other damages, but it also enhances its rich, natural color.
Effectiveness
The effectiveness of stone stealers varies depending on your chosen product and your maintenance practice. It’s crucial to follow the manufacturer’s instructions during the whole process and keeping good care of it. One thing is for sure, a good stone sealer will provide many benefits protecting your stone surface from hard stains, offering some water and moist resistance, enhancing durability, and making it much easier to clean.
Eco-Friendly
Eco-friendly stone sealers have great benefits for both the environment and human health. Usually, they are made of water-based formulas instead of harmful chemicals. These stones are nontoxic, release a low odor, and are much safer when contacting food. Plant-based sealers made of renewable resources or zero VOC sealers with little to nontoxic chemicals are also sustainable options. They release less harmful emissions into the air while being produced or used and create a healthier environment for both humans and pets.
