Cast stone designs can be aged to look older, using just a few easy and simple steps.
Encourage the growth of moss, lichen and a darkening of stone by painting your design with a mixture of natural yoghurt, semi-skimmed milk and either chimney soot, peat or silt. You can also encourage faster moss growth by rubbing established moss over the surface of your cast stone design. The moss spores will impregnate into the stone surface and activate growth over time.
Cast stone designs that are left in damp earth, shaded areas or amongst thick borders or grasses for several months will age much quicker than stone left in sunny areas of your garden.
An alternative to using the above instructions is to use Haddonstone’s Masonry Weathering Tint. This easy-to-use water-based formulation adds character to cast stone. One coat will add an antique-look, or additional layers can be applied to build up greater depth of colour.
