How to Remove Mould from Render?

DDAC is an acronym for the chemical compound diphenylamine chloride. It is a biocide that is used to remove mould from Render. DDAC has been used since the early 1900s and is one of the oldest and most effective ways to get rid of mould.

DDAC works by disrupting the cell membranes of mould. The product can be sprayed directly onto mould-affected external surfaces to break down the spores, which then wash away with rainwater. There are three main steps involved in using this type of mould protection.

When using DDAC, it is essential to protect plants and the surrounding area. First, remove any plants or objects from the treated area. Second, cover any plants or things in the surrounding area that you want to protect with plastic sheeting.

It is important to remember that DDAC is a biocide and can be harmful if it contacts eyes, skin or ingested. Always wear essential PPE gloves, goggles, and a mask when using DDAC and make sure to keep it away from children and pets.

Firstly we need to Determine the surface area that needs to be treated
To determine the surface area that needs to be treated with DDAC, first, take a photograph of the external surface and then calculate the square meters. Next, measure the height and width of the surface that requires treatment. It is generally easier to measure in m2, e.g. 18 m high by 4 wide.

Once the surface area has been calculated, it is essential to mix the DDAC with water in a spray vessel. The mixture should be sprayed over the surface that must be treated and then allowed to dry. If rain is forecast, it is vital to allow plenty of time for the solution to dry before the rain falls.

When using DDAC, it is essential to protect plants and the surrounding area:
– Remove any plants or objects from the treated area.
– Cover any plants or things you want to protect in the surrounding area with plastic sheeting.
– Spray the DDAC mixture over the surface that must be treated.
– Make sure to use a garden sprayer or paint roller to apply the DDAC mixture for best results.

It is important to remember that DDAC is a biocide and can be harmful if it comes into contact with skin, eyes, or consumed. Always wear gloves, goggles, and a mask when using DDAC and make sure to keep it away from children and pets.

Always read the manufactures guide for mixing chemicals.
