Usage Guide

Before you start-

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 the Patio & Block Paving Seal.

Application-

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.

Wait 4 hours before putting on another coat.

FYI - Really rough surfaces might need an extra coat.

Aftercare-

Surfaces should be routinely cleaned using Thompson's Patio & Paving Cleaner. Treated areas should be recoated approximately every 2 years depending on use.

Remove as much product from application equipment prior to cleaning. Clean brushes, rollers and any other equipment immediately after use with warm soapy water.
