D-mould an environment friendly, powerful, water based-mouldicide formulated to protect and clean most exterior surfaces from unsightly mould and algae growth.

It helps prevent from blackening, discolouration and slipperiness of these surfaces. D-Mould contains the active mouldicide and algaecide alkyl dimethyl benozylammonium chloride.

Recommended Uses

D-Mould is uniquely formulated so that when it is applied to raw timber, the treated surface weathers to a silky appearance. It is ideal to protect and clean timber, especially Western Red Cedar. Untreated surfaces such as decks can become slippery and dangerous due to mould growth. D-Mould will clean and protect these surfaces from mould growth. D-Mould is also suitable for other external surfaces e.g. paving, brickwork, tiles, painted surfaces, synthetic grass and canvas.

Test D-Mould on a small area of the surface to be treated, to ensure it has no adverse effect on paintwork, etc.
Directions For Use

Mix the 500 ml of D-Mould concentrate into 10 litres of water. Brush, roll, spray or mop a generous application onto the surface to be treated. Scrub the mould/algae affect surface using a nylon brush or stiff broom. Once applied, D-Mould kills any existing mould and natural weathering removes discolouration over a period of time. Heavily infested surfaces may require re-treatment with D-Mould 3-6 months after initial application. If treating blackened or mould affected wood, pretreatment by scrubbing discoloured surfaces with a household bleach or oxalic acid will help to clean it instantly. Rinse the bleached area with plenty of clean water and allow to dry. Apply D-Mould to prevent any further infestation of mould. Re-application of D-Mould every 1-2 years may be necessary to prevent re-occurrence of mould.

5-10 square meters per litre-depending on surface porosity.
