Defender CSD Pure AP675
Actichem’s Defender CSD Pure (AP675) is a proprietary impregnating sealer which consolidates friable material and strengthens the substrate. Although suited to a wide range of materials it is most popular with construction materials such as sandstone, limestone, clay and concrete. It reacts with the substrate material creating an extremely strong and durable bond which protects the substrate from structural weakening and erosion for many, many years.
Defender CSD Pure is clear solvent based consolidator ideally suited to heritage stone applications and stone in marine or high wind environments.
