Patio Paving Stain is a water-based paving stain for garden concrete stones and slabs. Available in 10 attractive earthy shades. For best results, apply the stain with a spray to maximise the absorption and shorten the application time. We recommend finishing off with a roller or brush, to ensure penetration into the stone pores. Available in 10 earth-tone shades. If the stones are already coloured, select a similar shade for the stain. For undyed concrete grey paving stones, any shade from this colour collection can be chosen.
