Block paving sealing and resealing

Look for rocking blocks, sinking tracks, loose edges and standing water. These may require investigation or repair rather than a surface finish. Coating visibly uneven paving can make it look different while leaving the cause unchanged. Identify whether the main concern is colour, cleaning, joint condition or movement.

Previous products matter too. A new coating may not be compatible with an old one, and the condition of the existing film can affect preparation. Tell us if the drive has been sealed before, even if you do not know the product name. Do not assume that a fresh application can be placed directly over every earlier treatment.

Preparation should follow the chosen product’s instructions and the paving specification. Dirt, growth and contamination can affect the finish, while remaining moisture can create application problems for products that need a dry surface. Weather and drying time therefore matter alongside the area to be covered.

Block paving joints also need attention after cleaning. Joint material should suit the paving and intended treatment. Re-sanding is not the same as sealing, and a sealed surface does not remove the need for sound joints and stable edges. Establish the sequence rather than treating cleaning, sanding and coating as interchangeable tasks.

Some sealers alter colour or sheen more noticeably than others. Ask about the proposed appearance on your type of block, including any trial area recommended by the manufacturer. A darker or glossier finish is a visual choice, not evidence of better structural performance.

Consider slip resistance, permeability and the manufacturer’s stated use. A product suitable for one paving system is not automatically appropriate for another. Where the driveway forms part of a drainage design, check the effect of the proposed treatment on that construction. Keep the original water route and maintenance requirements in view when discussing the finish.

Driveway resealing depends on the condition of the earlier treatment and the product instructions, not a universal calendar interval. Look at wear and compatibility before adding another coat. Excess build-up or treatment over a poorly prepared surface can create further work rather than improve the drive.

Driveway sealing cost includes more than the coating itself. Area, cleaning, contamination removal, joint preparation, earlier treatments and access all influence the scope. Compare driveway sealing companies on the specified process and compatible product rather than assuming identical work from a headline figure. Our sealing pros and cons comparison helps weigh the maintenance decision against leaving correctly maintained paving unsealed.
