Is Primer Necessary?

I'll be painting a wall a slightly darker shade that it is now. Is it necessary to prime again or can I just paint right over the current shade?

No but if it's been a few years you might want to at least clean the walls before painting

Trish, it is never wrong to prime, but often it is over kill. If your walls are of a low sheen and the paint appears to be of good quality, go ahead and just paint.

You prime to: 1) get adhesion to slick walls 2) seal porous walls, ie. new drywall or poor quality paint 3) affect a color change. Two coats of the finish paint however, will often cover better than a primer and paint, this because there is often more white pigment in paint than in primer. Primers serve multiple purposes, color change is almost secondary to its primary purposes.
