Congratulations asbestos cement siding is durable holds paint exceptionally well and is fire proof.
Preparing asbestos siding for painting.
Here at top coat painters we dial down the pressure and use a 4 step process.
Preparation before coating is the key to a successful paint job.
Pressure washers are over rated.
The biggest concern is that you should avoid power washing asbestos siding as it can chip or damage the siding and release dangerous asbestos fibers into the air.
It is hard to top.
I m placing a bid on painting this house with this type of siding.
Use a long handled brush and detergent.
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.
Be sure to use both a primer and top coat that are recommended for use on cleaned fiber cement siding as recommended by the manfacturer of both the siding and the paint.
When you are done cleaning paint the siding with a suitable primer.
Thinking of pressure washing and allowing to dry for a couple of days.
You must be careful not to damage the wood while doing so as the water pressure is strong.
Start at the top of the house and work your way down aiming the nozzle downward and keeping it moving constantly.
Powerwash the siding to remove any excess dirt or paint with a low pressure pressure washer.
On preparing the surface for paint.
Begin painting the siding with your choice of brushes and rollers making sure to check often for runs.
Surface is chaulky with very little flaking.
You do not want to scrape or sand the shingles directly as you could release asbestos but.
Allow the primer to dry completely.
Use tsp with both if you can get it in your area.

We do a final rinse again.
That said you ll still need to take some precautions if you decide to paint your asbestos siding.
The first is the possible and almost certain presence of lead based paint on the siding and the second is the asbestos in the siding itself.
Painting asbestos siding compared to other similar hardie board or fiber cement siding there is not much difference in terms of painting asbestos siding after you prepped and cleaned the surface.
Begin by analyzing a paint sample for lead content.
Then be sure that the siding is dry before applying either primer or paint.
We apply a soap mildew killer under very low pressure and allow it dwell on the substrate for aprox 10 to 20.
Maybe add a mild cleaner that wont harm the plants.
We rinse with plain water to pre wet the surface and remove very loose dirt.
