Cleaning old asbestos siding.
The choice is yours as far as whether you want to spray or roll the paint on.
Within a week you can come back and simply brush the moss or fungus off the surface.
Although asbestos is no.
The approach of removing the old shingles and replacing them with new siding is an option that many homeowners have pursued though probably not as safely as they should.
Double knot each bag.
The fibers are less likely to become airborne if moist.
Clean up for something like this could cost even more money.
Although most of those particles will be trapped in the water while you are washing it the water will eventually evaporate and release those particles.
Step 2 double bag the asbestos siding in leakproof transparent 6ml or thicker plastic bags.
Since asbestos is only dangerous when it is in a friable state you will remove the paint without sanding or scraping.
Scraping or brushing off old paint from asbestos siding is necessary before repainting but dangerous because it can release small asbestos fibres.
Your are able to pressure wash but you must use a lower pressure setting in order not to chip or damage the siding and release dangerous asbestos fibers into the air.
This means that you ll have to take some extra time cleaning and prepping the siding before painting and rely instead on a garden hose sponges and good old fashioned elbow grease.
Take your soft brush and use it along the siding to remove the dust or chalk that you want to clean.
The bleach will kill the organic matter.
Do not overload the bags creating the danger of bursting open during handling or disposal.
Never use a hard or abrasive brush to clean cement fiber siding.
This means you need to be careful and take your time.
Remove any biological growth such as moss and fungus from the surface of the siding.
In the 1970s the public learned what the asbestos industry had known for 60 years that asbestos is highly toxic and that inhaling its fibers can cause lung scarring lung cancer and mesothelioma.
Often since asbestos siding holds paint so well there won t be any but if there is it you must remove it before you can repaint.
I have been told not to power wash asbestos shingles just use tsp lightly scrub and rinse off with hose.
If you prefer to use a soft cloth to handle the debris wet it and wipe the siding until it is clean and once again rinse with the hose.
Once the surface is prepped and cleaned there s really no difference when it comes to painting asbestos siding than any similar fiber cement or hardiboard siding.
Moisten the asbestos siding with a hose.
Asbestos was used frequently from the beginning of the 20th century in a variety of building materials.
Then rinse with the hose.
Asbestos cement siding is very brittle and can be easily chipped cracked or broken.
Just paint the siding and seal the asbestos in.
