I need to paint the rear of a rental (outside) that is cinderblock construction. It was already painted white when I bought it but it needs a repaint job now and I'm planning to just paint it white again. Not sure what kind of paint to use for this. I've read mixed things about elastomeric.

Is Behr Masonry paint a good choice for this? Also would you use flat for the finish or something else?

thanks.

You need exterior masonry paint.

DIY? then:

1. Power wash.

2. scrape and brush loose paint off.

J(FL),

I am firm believer in Primer, especially Bonding type Primers, and I prime everything prior to top-coating regardless of whether it has been previously painted or not. I am sure you can find an 'expert' that will disagree with this but the fact is a good quality Primer will provide a good base coat, especially with block which is very porous and needs those pores filled.

Again, today my crew is putting Valspar Bonding Primer on the interior block walls of a garage, which was painted with some type of white paint 30-40 years ago.

Now, if you have concrete block walls where moisture is seeping through, there is a product called Drylock which is supposedly a better choice. I have never used it so I can't comment on whether it is worth the extra money.

Drylock works best on unpainted concrete. It works by blocking the pores, so painted surfaces don't allow that. If you don't have a water issue, it isn't worth the extra money. Valspar bonding primer is thick like pudding, yet spreads easily.

My local Lowes has the Valspar rep in quite a lot. I have asked him plenty of questions and he is good at giving real life recommendations. (yes use the exterior paint with good ventilation on the window sills) I have called the customer service number to ask questions. They are too cautious in their answers (never use exterior paint inside).
