waterproof sealant

I had a Beaufort flag patio (https://www.tobermore.co.uk/homeowner/products/paving-flags/beaufort-flags/) laid last year and just given it a quick clean. Was looking for recommendations for a sealant? Had a look online but just curious to see what's recommended on here, Cheers, Jordan

Hi The steel drum on my Parkside wet/dry vac slowly leaks. Can anyone suggest a waterproof sealant brand that would be ideal to keep the vac going for another year or so? Thanks!
