Repainting asbestos siding.

In most cases you can pry out old pieces in one intact piece which is very important as asbestos only becomes dangerous when it s broken and made friable and fibers are released into the air. Our method of choice to first apply zinsser peel stop triple thick primer which is a water based acrylic binding primer designed to penetrate and stop previous coatings from peeling. A typical procedure is to install furring strips on the existing wall avoiding breaking the existing siding.

A common remodeling practice is to install new vinyl or aluminum siding over cement asbestos shingle siding as well as over many other older siding materials when the old siding has become damaged leaky or cosmetically ugly. Take appropriate care and precautions when removing and disposing of old asbestos siding pieces. Begin painting the siding with your choice of brushes and rollers making sure to check often for runs. The choice is yours as far as whether you want to spray or roll the paint on.

You can roll it or brush it on but make sure you get under the small lip at the bottom of each asbestos siding shingle. Begin by analyzing a paint sample for lead content. One concern when repainting this type of siding is the small gaps between the shingles.
