Painting Concrete Block Wall

Hi,

My next door neighbor hired a contractor to paint his side of our concrete wall (sharing) last year. The final result is very smooth and I like it. While the contractor was doing it, I was watching. He pressure washed the walls and then he sprayed the wall with about 2 coats of paint. I think they did the entire job (around the house) in a total of 3-4 hours, including cleaning the wall too. I have asked my neighbor if the contractor used a self leveler or some type of filler? He does not know.

How can achieve the same smooth result without mortar grid lines? I would like to do it by rollers since I don't have an air compressor for painting.

Thanks

Is this a block wall or poured concrete wall?
Even when spraying it's best to back roll the paint.

Assuming you meant block wall I know of no paint that will hide the mortar joints although they could be filled in with stucco. I normally roll on a coat of block fill [fills the pours and primes the block] and then a coat of decent latex house paint.

Hi MarkSR,

Yes, it is a Cinder Block Wall similar to these: https://images.search.yahoo.com/sear...v-web&fr=crmas

Would you be able to recommend a block filler that I can buy from Home Depot?

Would staining be easier than painting? Just a thought.
