ALGAE, LICHEN & MOULD Crikey Mikey Pavement Slab Path Treatment Extra Strong 10L Kit

This 10L kit of Crikey Mikey Extra Strong, supplied as 2 x 5 litre containers with a 3-litre spray applicator, protective gloves, and safety glasses, gives a mid-sized ready-to-use package for properties with a moderate amount of affected area, more than the single 5L bottle covers but without committing to the full 20L contractor pack. It's the strongest formulation in the range, built for neglected surfaces where algae, lichen, or mould has had time to take hold, and works fast, with visible results in around 12 hours. Used neat it treats up to 10m² per litre, and for routine maintenance it can be diluted up to 6 parts water to 1 part product.

Made from industrial-strength chemicals normally only available to trade, it's suited to block paving, fences, walls, brickwork, stonework, paths, patios, decking, gravelled areas, and roofing. It's not suitable for every surface or situation: avoid use on lawns, flowerbeds, vegetable plots, or near trees and shrubs, and don't use it on tarmac or anywhere lead is present. Keep people and pets off the treated area for 24 hours or until it's dried. Performance is best in temperatures between 10 and 20°C. As a batch-produced product supplied fresh weekly, it should be stored and used according to the label instructions.
