Di-Ard is a biodegradable quaternary ammonium compound (9.2% dialkyldimethyl ammonium chloride) - this basically means it is a water based concentrate which is used to kill algae, mosses, lichen, wood rotting fungi and moulds on external hard surfaces. It can also be used as a wood preservative.
Di-Ard is simply diluted with the recommended rate of water and sprayed or washed over the affected area.
No rinsing, scrubbing or powerwashing is required - just leave the product to work its magic.
Di-Ard is readily bio-degradable and non bio-accumulating. Once the treated area has dried the surface is safe for animals, pets and children. Di-Ard is also safe to treated surfaces and has NO staining properties.
Di-Ard can be used on external hard surfaces and because it contains no abrasive properties in can be used on delicate surfaces that powerwashing may damage.
Di-Ard is sold as a concentrate and can be diluted to your own requirements.
