A week ago I painted a room in our house, which was previously painted,
with light green silk emulsion paint. I washed the walls first with a
very mild detergent solution. The old paint was fine, no damage or
The first coat went on fine, but then when the second coat went on it
started to crack - like the paint on old oil paintings, and over the
next few days it got really bad.
So I left it for a few days to dry out, then put quite a thick third
coat on, the same thing happened - not new cracks - just the same ones
showing through. It looked like a muddy field when the baked by the sun.
So now, I sanded down the worst areas, not to the bare walls, just
enough to take the tops of the cracks (its very tough stuff, I doubt I
could get down the walls if I tried), and painted again with a one coat
quality thick stuff paint. Guess what, the cracks started to come
through again - its not that you can see their shape - they actually
seem to pull the new coat apart and you can see the original colour. Its
like painting on wax.
Apart from the first two coats, I am now only painting in little
segments to see what works, so my walls look like a patchwork quilt.
Does anyone have any suggestions as to how to over come this. I dont
really want to have to put a quarter of an inch of paint on it the get
Thanks in advance.
