Limestone has become a favourite choice as a natural stone for patio designs in the UK this last few years. We stock limestone in black, yellow and blue colours. With the Black limestone having a price point half that of Brazilian slate paving, with a striking consistent charcoal grey black colour when dry/unsealed, black limestone has an even more eye-catching dark black colour when sealed with a wet look sealant. Some customers play with this contrast further by using our natural Joint-IT jointing compound others prefer to use the dark grey Joint-IT to make the whole patio space consistently dark. 

As a rule we always recommend sealing Limestone as unsealed it is prone to fading from UV exposure. This again can be used to good effect, we have a customer who uses the yellow limestone unsealed, he informs us that it fades to look very much like a traditional York sandstone. Nice trick from a tradesman!
