Thanks Mag
Hi Mag, we have so far power washed it and it looks even worse! God what a mess! A painter we know gave advice along the same lines as your friend. He said it would probably take an oil based undercoat to seal it and then a few coats of the usual emulsion. He said to do a test patch down low to see how it turns out. I wonder if the oil undercoat is the same type of thing as the ESP sealer your friend mentioned. I will try to find out before we do any more damage.
