Surface know-howWhy seal block paving at all
The honest answer: you do not have to. Sealing changes how much the surface absorbs and how easily it cleans - not how long it lasts.
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.
