Should You Seal Quartz Countertops?
The Short Answer: No
Unlike natural stone surfaces such as granite or marble, quartz countertops do not require sealing. Because they are engineered to be non-porous, quartz surfaces naturally resist moisture, bacteria, and stains without the need for a protective sealant.
This characteristic makes quartz an ideal option for busy households, commercial spaces, and those who prefer low maintenance quartz countertops for busy families.
Why Quartz Countertops Don’t Need Sealing
Engineered for Durability
The manufacturing process of quartz slabs combines about 90–95% ground quartz with durable polymer resins. The result is a dense, impermeable surface that doesn’t have microscopic pores like granite or marble. Here’s why sealing is unnecessary:
- No moisture absorption
- No need for regular reapplication of sealant
- Stain and scratch resistance built-in
- Long-lasting shine and color retention

When Might Sealing Be Considered?
Although not required, in rare cases you might consider sealing:
- Older or damaged quartz surfaces that have lost their factory coating.
- DIY installations where fabrication errors expose raw edges.
- Commercial kitchens requiring additional sanitization measures.
