What a sealer does
It soaks into or coats the surface to resist oil, dirt and moss, and can lock the jointing sand in place to reduce weeds.
The benefits
Easier cleaning, stronger colour, stain protection and fewer weeds.
The drawbacks
Poor application can leave a patchy or slippery surface. It can also make the paving less permeable, and needs reapplying.
When to seal
After a thorough clean and re-sand, when the surface is fully dry, and in suitable weather. Do not seal over damp or dirty paving.
Choosing a finish
Matt and satin finishes give a natural look and better grip than high gloss. See paving sealing.
