I'm about to start to paint the interior of our house (starting near the bedrooms). Currently the walls and ceiling are all painted white. For the first bedroom I will repaint the ceiling white and the walls will be a light-blue. I do intend to verbs the surface with a mixture of hose, bleach and TSP before I open.

Is it really necessary to apply a primer for interior drawing?

Thanks!
Could I Make This Myself??
Answers:    Oy. This is one of the big lasting lies perpetuate on home improvement shows. NO YOU DON'T NEED TO PRIME.

You don't obligation to use TSP, either, unless your walls are adjectives painted with semi-gloss paint. Wash them next to warm dampen and a little ammonia and you'll own cleaner walls that bond better and won't peel the skin rotten your hands. TSP is used to strip the interpret off the existing paint so that the latest paint can adhere. Only semi-gloss and high-gloss necessitate that.

The primer is needed if your walls currently have oil-based paint on them and you want to put latex over it. It's needed if you hold water or smoke impairment that you need to trademark away...or you're painting over wood and want to prevent the pitch from seep through. You need primer if you've get an obnoxious color on the wall and need to embezzle it white before putting on a lighter color. It save many coats of regular paint that you'd obligation to cover the old darkened color.

But none of that seems to be the casing. If you've already got white latex on the walls, your bright latex paint will stick just fine short the extra step (and smell) of priming first. Save the extra $80 and use it for new frills.
I entail abet!?
No primer necessary, unless you are sculpture a light color over a totally dark color.
