Does Exposed Aggregate Need to Be Sealed?

Sealing should be considered as part of the finish strategy

Exposed aggregate sealing can change the way a surface looks and is maintained. Depending on the selected product and site conditions, it may enrich colour, support cleaning or add a level of surface protection. The right approach depends on the project.

What sealing can influence

A sealer can affect sheen, colour depth, water behaviour and the way the surface responds to dirt or staining. These qualities should be considered alongside the desired appearance and the practical use of the driveway or outdoor area.

Maintenance still matters

Sealing does not remove the need for routine care. Cleaning, avoiding harsh products and responding to spills or organic buildup early can help maintain a more consistent surface over time.

Ask about the selected aggregate finish, expected use, surrounding trees, exposure to weather and preferred visual result before deciding whether sealing is appropriate for your site.
