Actichem Defender CSD is clear solvent based water repellent ideally suited to heritage stone applications and stone in marine or high wind environments.

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. It is a proprietary impregnating sealer which consolidates friable material, strengthens the substrate and provides powerful water repellent properties. Available in 500ml, 5, and 15L.

Recommended applications:

Formulated to provide premium protection to porous construction materials and is ideally suited to the protection of heritage and delicate/friable/crumbling stone. Defender CSD is ideal for limestone, sandstone and concrete structures.

Expected Wear – Defender CSD will provide premium protection for up to 15 years and in many applications, several years longer. However application methods, weather conditions, traffic, harsh cleaning methods and substrate type will affect wear. Avoid use of solvents, strong acids and strong alkalis for extended sealer life.

It is recommended that the sealer be re-applied every 8 – 12 years where harsh conditions exist.
