A sealer reduces how much a surface drinks, so water, grease and dirt work their way in more slowly and clean off more easily. These guides cover choosing the right product for your surface, preparing it properly, and working out how much you need.
Preparation and applicationWhen to seal, how to apply sealer with a roller, brush or sprayer, how many coats to lay and when you can walk on the paving - step by step, with times for specific sealers.
Preparation and applicationCoverage comes as a range because absorbent substrates drink more. How to get from that range to litres, and why one pack of spare is worth buying.
Preparation and applicationA sealing job that goes wrong is almost never the sealer's fault. Five things to check before you open the pack - and why the order matters.
