Last weekend I started painting my clapboard house. I know about normal
surface preparation (cleaning, light sanding), but the east and west walls
are VERY badly alligatored, peeling, etc. and I suspect that I could make
my life easier if I knew more advanced surface preparation techniques.
The house was painted a few years ago with a dark brown latex paint plus
some bonding agent, over one or more coats of oil-based yellow. The two
bad walls peel right down to the bare wood, so the bond between the latex
and oil-base paint isn't the problem. I'm inclined to believe the theory
that brown paint heats up from the sun. Anyway, I have this scraper tool
(not a spatula) from the paint store that easily takes off the loose
paint. Problem, it then leaves me with a very uneven (huge, sigh) surface
where the chips of paint still tightly bonded to the house remain. So, I
can spend a portion of my life sanding this by hand, but..... Is there a
better way? I have an electric drill, do I want a sanding attachment? Or
what? Thanks for any help.

I've recently repainted my old farmhouse which had the same problem. I rented a disc sander (*very* high RPM - *much* better than an attachment for your drill) for about $15 which did the job. The drawback to this approach is that it leaves swirls on the wood. This doesn't bother me much (in fact, you won't notice it after a few weeks), but some people are more particular. Another option is a water blaster. These are normally used for cleaning driveways etc, but people around here use them for getting the old paint off a house too. These can be rented too - it is basically a compressor/pump that you hook your garden hose up to. Sort of turns it into a super hose - like the kind at the do-it-yourself car wash. This can knock off a *lot* of loose paint fast. The disadvantage here is 1) if any wood is rotted or soft the pressure can actually gouge the surface, and 2) you get very wet. Heat guns are the third choice, but they are slow and don't work very well for large areas. Lastly, there's scrape and sand: my least favorite (oh my aching arm). Good luck! -- Of all the things I've lost, I miss my mind the most. Michael L.

I was advised to prime areas which blister and peel with boiled linseed oil, then the normal primer, and then the finish coat. I selectively use the primer over bad areas when painting old previously painted wood. I use a belt sander and keep the belt wet to prevent the paint from clogging up the sandpaper.
