Ask what protection you need
Think about the location, expected spills, exposure and desired appearance. A sealer may change colour or sheen, so confirm the finish effect on a sample before treating the whole area.
Customstone SA’s FAQ notes that a sealer can help reduce staining and efflorescence, while stressing that the sealer must be suitable for concrete products.
Check compatibility first
Ask the paver supplier and sealer manufacturer to confirm compatibility. The installer should consider curing, surface preparation and weather conditions in line with the product directions.
A professional sealing company can assess cleaning and application requirements. Avoid applying a coating simply because it is sold for another paving material.
Plan ongoing maintenance
Sealers may need care or reapplication according to their product instructions. Keep a record of the product used so future cleaning and repairs can be planned consistently.
Read the [care FAQs](/faqs/) and ask about your specific product before sealing.
