We're in the process of painting a bedroom, using one of B&Q's "New
England" paints. The walls were previously painted with that looks
like a vinyl silk, were clean and appeared sound before we started.
When we put on the first coat, a small number of bubbles, 3-5mm
across, started appearing on the walls - these could be "burst" with a
finger or the point of a screwdriver, but left a mark on the wall.
The second coat, however, is *far*
worse - within a few minutes of
painting one section of wall, at least 50 of the same bubbles had
appeared in an area less than 1m^2 :-(
I fear that the only remedy is to wait for the second coat to dry,
sand down everywhere that the bubbles have appeared, and recoat.
- any ideas on what the cause of this is?
- why would it be worse on the second coat than the first (1st coat
had been on the wall for 48hrs before starting the 2nd)?
- how can this be prevented?
I have visions of the room being measurably smaller as a result of n
coats of paint by the time we've finished :-(
