Why seal at all?
A good patio sealant soaks into the pores of the stone and forms a barrier that resists water, dirt and the spores that grow into moss and algae. It also makes the surface easier to clean in future – grime lifts without the jet.

Sealing your patio after jet washing
A freshly cleaned patio is the perfect time to seal it – locking in the clean and holding off weeds and moss for far longer.

Jet washing lifts years of grime – but if you walk away without sealing, moss, algae and weeds start recolonising almost immediately. A single afternoon of sealing makes the clean last far, far longer.

Let it dry completely first
After jet washing, the paving needs to be thoroughly dry before any sealant goes on – usually a full dry day or two. Sealing into damp stone traps moisture and the sealant fails. Pick a clear, dry spell and don't skip the wait.

Choose the right sealer
Sealers range from natural, matt, water-based finishes to glossy wet-look sealers and coloured options. Match the finish to your patio – most people want the stone's natural look with a subtle sheen rather than a shiny plastic effect. Read the coverage rates and buy a little more than you think you need.

Apply evenly and maintain
Work in small sections with a roller or brush, keeping a wet edge so there are no lap marks, and resist walking on it until it cures. Re-seal every couple of years (sooner in heavy shade or footfall), and you'll clean far less often in between.
