If you’re considering granite as a countertop option, you might be wondering: does granite stain? It’s a common question, but unfortunately, there is a lot of misinformation circulating on the internet. Let’s set the record straight.
The Truth About Granite Strains
Technically speaking, granite can stain, but it’s relatively uncommon. Like all natural stones, granite is porous to some extent. However, its level of porosity is relatively low compared to other stones like marble. This is why granite is a popular choice for building exteriors worldwide—it is highly resistant to water and minimally absorbent.
In most cases, when a liquid is spilled on granite, it will remain on the surface for a few minutes before drying out. However, if the granite is unsealed, the liquid may penetrate the stone’s pores. Nevertheless, even when this occurs, the stain is not necessarily permanent. A topical paste can be applied to draw out the moisture and effectively remove the stain in most cases.
To further minimize the chances of staining, it’s advisable to seal your granite regularly. By sealing the granite annually, you can prevent water rings, temporary dark spots, and stains. At Arch City Granite and Marble in St. Louis, we use Dry-Treat Sealer, a top-of-the-line sealer with advanced “Nano-Technology” that provides 15 years of protection.
The alcohol-based formula of our sealer fills the pores in the granite, creating a barrier against liquid penetration. Sealing your granite not only safeguards it from stains but also improves its overall hygiene and makes cleaning easier by preventing food liquids from seeping into the stone.
So, how can you seal your granite countertops?
It’s a simple process that you can easily perform yourself. Follow these steps:
- Clean your granite counters with water and ensure they are completely dry.
- Shake the sealer well and apply it liberally to the entire surface of your counters using a clean paint roller (you can also use a clean paintbrush or paper towels to reach the corners). The goal is to create a thin film of sealer on the entire stone surface.
- Allow the sealer to soak into the counters for 15 minutes, and then wipe off the excess with a clean cloth.
- If you have white granite or a stone that is more prone to staining, consider applying a second coat. Wait at least 48 hours before applying the second coat using the same method as before.
- Wipe off any remaining sealer from the counter using clean towels or paper towels.
- Ideally, let your countertops sit for 24 hours before using them.
- Clean your rollers or brushes with water and store them in a clean place.
