Using the spray makes the task easy and quick, as it prevents the flaking process of asbestos pieces into the paint container and the brush. You can also use a hair paintbrush for this purpose. Apply the second coat of paint when the first coat gets dry.

Addition of plastic sheeting

  • If you want to create a barrier among the elements and prevent the rubbing against the painted asbestos siding, you can use plastic sheets. It will add a layer that will reduce the friction and also adds protection in between. 
  • On the top of the exterior wall, put the top edge of plastic sheets over the siding.

Nailing into asbestos siding:

  • It is a crucial step. It can be done by placing many nails in the plastic sheets when the top of the plastic sheets is completely attached. Make sure that the nails are correctly put to secure the plastic sheet. 
  • Repeat this process on the edges too. Make sure that sheets are overlapping when you are using more than one sheet by nailing them.
  • You can also use the shovel for digging the required area so that the sheets may cover the big area of the wall. The excess number of sheets should be trimmed with the help of a utility knife.                                

Addition of foam board

  • If you are trying to install the siding on the prior siding, you need an even surface with plastic sheets. Cut the foam board, matched to the exterior wall that needs covering according to the measurement.
  • The exterior foam board should be waterproof, mold and mildew-resistant to reduce the damage in future. 
  • Now place and screw the foam board on the wall.
  • The galvanized screws should be used at the existing siding on the corners. Now fasten the screws after the required distance.
