The cleaning & prevention of black spot from:
• Natural stones i.e. sandstone
• Porous clay-based & cement-based block pavers
• Removes black spot where pressure washing fails
• More effective than other cheaper black spot removers due to its unique blend of ingredients
• Use prior to sealing with one of our breathable sealers
• Works in conjunction with Kingifsher Bio-Wash to prevent the return of black spot.
This product will remove black spot lichens from sandstone, concrete, brick & block pavers. It has a non-acidic formula so can be safely used on limestones and cement-based block pavers. It is highly effective; this product succeeds where pressure washing, and weaker alternatives fail.
Amazed by this product. Easy to use and within a very short time the offending spots had disappeared, brilliant.
