Easy to clean

For use on all block paving and flag stones

Coverage 6m2 / Litre


Make sure block paving, jointing sand and paving slabs are dry before you start. Give the surface a decent scrub with a stiff bristle brush to remove any dust or dirt. If you have any mould or algae, use some Thompson's Advanced Patio & Block Paving Cleaner. If you've got oil stains, use Thompson's Oil & Drive Cleaner.

Make sure any cleaners are rinsed off the patio & it's dry before you start applying One Coat Patio & Block Paving Seal.


For best results, use on a dry day above 10C. On cold & damp days, drying and re-coat times will take longer. Give the tin a good shake. Pour the tin into a roller tray and use a long pile roller to apply in long smooth strokes. On textured block paving, make sure any puddles are spread into dry areas.

It's just one coat, so that's it, job done!

FYI - Really rough surfaces might need an extra coat.
