textured wall issue
so our new house (built in '83) has textured walls in every room and some strange paint choices to boot. we decided to tackle the guestroom which was a demin blue color with a deep texture (that is curiously a totally different texture than the other 2 BRs). after priming with kills2 and painting a lighter blue flat latex, i found that the whole job could be scratched off with a fingernail. areas that i had taped off will peel down to the bare texture (i.e. through both my paint and the existing paint job). it appears that the previous owners did a plaster coat of texture and did not prime before painting.
should i scrape everything off and start anew? how would i go about doing so? should i just hire a pro?
