Painting asbestos soffits
My house was reroofed 40 odd years ago and has asbestos soffits. They
have been painted with the pink masonry paint as used on the walls. They have a tendency to flake over time (? masonry paint not appropriate), but not everywhere. I am currently painting the fascia, and am wondering whether it would be better to: 1. Paint with masonry paint again over the existing paint after scraping off the flaky bits. 2. Paint with masonry paint after sanding off all the old masonry paint off first (yes, I know, very carefully, with full protection) and ? using stabilising solution. 3. Paint over the masonry paint with white primer, undercoat and gloss over the existing masonry paint after scraping off the flaky bits. 4. Paint over the masonry paint with white primer, undercoat and gloss after sanding off the old masonry paint off first and ? using stabilising solution. All thoughts gratefully received. Keith |

Keith Soffits have a tendency to peel no matter which paint you use, although I'm not sure why as they always seem to me to be the most protected part - they usually start to peel before the fascias for some reason.....I had a theory that it could have possibly been the heat radiating out from the walls on hot days and rising up to the eaves, but having just finished painting a hipped semi with 3 sides of soffits, 1 North facing, 1 West and 1 South, and they had all peeled in fairly equal proportions, so that theory has gone out of the window. Personally I'd go for undercoat and gloss, and try and do them every 5 years or so -- Phil L RSRL Tipster Of The Year 2008 |

If both sides were painted to problem would be solved. (Assuming it was dry when you painted) The accumulations of moisture behind the paint forces it off. The answer is to paint with one of these vapour micro-porous paints. If you are bent on scraping it, wear a mask and don't take the asbestos cement dust in the house. Ideally wear disposable overalls and head covering. |

Painting asbestos soffits
I can not see why anyone would want to scrape/sand the surface of
Chrysotile asbestos fibre soffit cement board - it is perfectly safe stuff in terms of wet sheet removal, but not so safe when treated in such an abrasive manner :-) Soffit boards are often black with mould around house vents, I suspect humid air exiting the house and condensing on their surface. Conventional undercoat & gloss tend to act like a plastic bag if one side is porous to moisture, they will bubble & flake. You basically want a white stain which is highly permeable. Prehaps Sikkens onol undercoat on its own would do, it is white, MVP, overcoatable. I would not use the top-coats because whilst they are overcoatable every 5-12yrs (depending on which one) after about 4 overcoats you need to restore to original surface. They do "wear" by chalking rather than flaking. That is probably so far into the future it does not matter, but you want a paint that can breathe because soffit boards do suffer moisture loading from the other side. |

So you were given a government site reference, which states both in words and graphically that the rate of death is rising, but you claim otherwise with no basis offered for your view.

Hello Dennis NT Asbestos related diseases. Lots of people are affected and don't know it.Bit about it here. http://www.hse.gov.uk/statistics/causdis/asbestos.htm You're not seeing the other diseases. There are others. (Same site different page.) |

Hello Dennis The recording has changed. It happens frequently with gov. statistics to baffle the people that just read the end figures. |
