I've never heard of "Maple" can you post a photo of the paving?

It's one of the really soft, garishly coloured, Indian sandstones - not quite as repugnant as Rainbow, but heading in that direction. :p

Ah right, to the OP, that paving then will drink sealer, I'd leave it and don't seal, just keep it clean a couple of time a years.

If you do go the sealing route do NOT, use a surface forming sealer. It has to be an impregnating sealer for outside natural stone, IMO.

Yes, Roger, it does indeed drink sealant, and it hangs on to moisture within its structure for longer than a lot of other stones, so it's one of the worst for being hit with 'Cloudy Sealant Syndrome'.

I'd agree about the impregnator, definitely, and if it must be sealed, I'd leave it a month or two until we've had a week of really hot, dry weather to ensure as much of the moisture is driven off as is possible.
