I want to seal my outside slate patio with a heavy duty high gloss sealer, which product would you recommend please?
You have a couple of options (links below) the Heavy duty sealer is the cheaper of the two and is easier to use but wont last as long, whereas the High gloss PU will last longer but you have to make sure that the paving is 100% dry and that you will have at least 5-6 hours of dry weather once it has been applied.
