Granite countertops are a luxurious and durable choice for any kitchen or bathroom
Granite countertops are a luxurious and durable choice for any kitchen or bathroom. Whether you have elegant black granite countertops, timeless white granite countertops, or distinctive blue pearl granite countertops, protecting their surface is essential. One of the most critical steps in preserving these natural stone surfaces is using the right sealer—but what is the best thing to seal granite countertops with?
In this guide, we’ll explore the best sealers, application tips, product types, and how to ensure your granite surfaces stay stain-free, shiny, and stunning for years.
Why Sealing Granite Countertops Matters
Granite is a porous natural stone, which means it can absorb moisture, oils, and bacteria if left unsealed. While polished granite countertops offer some resistance, even they need sealing to prevent staining, etching, and dullness—especially in high-traffic zones like granite kitchen countertops or granite bathroom countertops.

Types of Granite Sealers: What Are Your Options?
Not all granite sealers are created equal. Here’s a breakdown of the most common and effective types available:
1. Penetrating/Impregnating Sealers (Best Choice)
These are widely regarded as the best thing to seal granite countertops with. They soak into the stone’s pores and form a protective barrier that repels moisture and stains without changing the appearance of the surface.
- Ideal for honed granite countertops and custom granite countertops
- Long-lasting (up to 5 years with proper care)
- Breathable formula allows moisture vapor to escape
Recommended for: All granite types, including granite countertops for outdoor kitchens
2. Enhancing Sealers
These not only seal the stone but also enhance the color and depth, especially in black, brown, and honed granite countertops.
- Adds a wet-look finish
- Excellent for deepening dark hues
Caution: Not suitable for every countertop style—test first.
3. Topical Sealers (Temporary Protection)
These create a protective layer on the surface but wear off quickly. They’re best for temporary solutions or budget fixes.
- May require reapplication every few months
- Can leave residue or alter the finish
