Consider encapsulation of the lead-contaminated wall or area. Doing repairs involving lead-based paints or items is not recommended. Cover exposed areas. If the area being worked on is large, such as when a wall is being torn down, plastic should be used to cover and seal off entrances and ducts and to protect furniture, carpets, rugs, and floors from paint dust and chips. Dispose of plastic coverings carefully and properly.
Dust is kept down by wetting painted surfaces before they are worked on.
Areas are cleaned up thoroughly. Dust and chips are picked up with wet mops or rags soaked in water. Wear protective gloves. Some people recommend using trisodium phosphate or a phosphate-containing powdered dishwasher detergent with the warm water. Mops and rags are thoroughly washed after each use to prevent recontamination.
