How to make Waterproof Limewash The Traditional way

This is where we take our quick lime, mix it with talow and water. A chemical reaction takes place where the water boils with the heat of the chemical reaction, melting the fat and the fat gets integrated into the lime wash 'furring' up the pores and making the white wash water proof. Its like Goretex for walls! The way it works is that it makes the pockets of air in the lime wash 'furry'. This stops water droplets penetrating the skin but it lets vapor escape. It becomes a breathable membrane. Its ideal for African mud buildings because it means you can paint the mud and it becomes water proof, stopping erosion without the need of expensive cement.
