Primer and Prep for Orange Peel Texture
Been using this forum for years for various projects around the house but can't seem to find a definite solution to my problem. I am looking at painting the hallways and stairwells in our apartment building, all of which are orange peel textured.
What I do know;
1. Latex paint overtop is not an issue. The walls passed the sponge test and a spot application of paint with no peeling or mushiness.
2. I am using recycled latex paint for the finish coat (it's cheap and our HOA/Strata doesn't have much money). I have used it in my place and was actually quite impressed for the price.
What I'm trying to decide;
1. Do I actually need to prime the walls first, and if so, what type of primer is recommended? There is 20+ years of wear and tear, various bug smears and marks from usage. I was hoping a primer would help cover any smells or stains that have soaked into the walls before applying a topcoat. Should I use a damp cloth to wash the walls first? TSP? I was going to use Kilz Original (oil based) but only if I can determine that it provides an added advantage.
2. The walls are currently white and will mostly be painted a cream colour except for some light brown accent walls.
Thanks!

Welcome to the forums!
Normally there is no need to prime painted walls prior to repainting. The 2 main exceptions would be if adhesion is expected to be an issue [like painting over oil base enamel with latex] or there are repairs that need to be sealed. Water and ink stains would need a solvent based primer to seal the stains.
Sometimes on older paint jobs or with drastic color changes it is beneficial to use a primer to facilitate coverage although a 2nd coat of finish paint is also an option. I would only use a solvent based primer if there are either stains that need sealing or adhesion issues are expected. I would not use latex Kilz! .... there are better latex primers available.
TSP is a great detergent but it must be rinsed well! It's always better to paint clean [or semi clean] walls as opposed to painting over dirt/grime. Cleaner residue can cause adhesion issues so that must also be considered.
