My home is 50 years old and has asbestos shingles. Needless to say, the house needs a paint job. What do I need to do? Can you even paint these things? Help!!!!

Yes you can paint them and they hold very well.
The first thing you need to do is wash the shingles down to remove dirt and mildew. Jomax is good product to use and all you need is a pump up garden sprayer and a hose to use this product. You do not want to scrape or sand the shingles directly as you could release asbestos but otheriwse you will be fine. Allow the shingles to dry for a couple of sunny days before you start to paint them. Then you will need to prime the shingles with an exterior acrylic primer, such as Duron Bond-N-Seal and finish with 2 coats of either a flat or satin acrylic house paint, such as Duron Weathershield. I feel that you will need to coats of finish to get an even look if it has been many years since it has been paint or even it if never and the paint job will last longer also.
Happy painting.

I beg to differ on the primer. Asbestos shingles chalk badly - even after a power wash - you are likely not going to be able to remove it all.

Latex products won't stick to chalk - alkyds will. Use an exterior oil primer - and two coats of 100 Acrylic Latex topcoat.....

The primer i reccomended is modified with an alkyd resin and will stick to slightly caulky surfaces, but if you can't get that product you do your own by adding EB (Emulsa-Bond) by the Flood Company to an acrylic primer and that will work great. That way you will not have to deal with an oil based paint and all the clean up and disposal of the dirty thinner.

Some of the asbestos shingles laminate is flaking. Is there any way to prevent this?

I read the advice about how to paint the asbestos shingles, but I am concerned. The shingles are extremely snug against one another. If I paint them as suggested (2 coats of primer) and then 1 or 2 coats of house paint, the entire outside of the house will be extremely sealed. Won't the exterior paint start to blister / bubble as interior moisture tries to escape, regardless of how good the paint is? In fact, won't the problem be worse with better paint?

You should apply only one coat of primer as that is all you need, as anymore is just a waste. Then you can apply one or two coats of finish paint over the primer and if is badly weathered the two coat route will be best for the long haul. The house will not be sealed up to tight as acrylic paint allow moisture to escape not hold it in. No the problem will not be worse with a better product as on an exterior you want the better resin package for long term durability.

Hope this helps out.

I really hope your suggestions work well, I am a single mothere and my twelve year old son and I are preparing to paint the house, the previous owners had attempted this, but the paint in peeling, apparently they had not investigated the situation. If there are any more suggestions please let me know. Thanz

I painted my 70 yr old house with BEHR Premium Plus 1 Multi-Surface Primer and Sealer Exterior 2 yrs ago. It is blistering like crazy now. I washed the house and let the shingles dry in the sun for a few days first as well. Acrylic exterior did not stick. I am trying oil base next time. At $40 a gallon you would think it would stick.

In New Orleans the problem with abestos tiles is mildew. Has anyone tried twp mildew sealer? We just brushed it on a section of tile after cleaning as much mildew off as possible and it looks pretty good. Oil has worked the best as far as not flaking off but mildew bleeds through.
