how to paint a block wall?
Answers:
That is somewhat of a trick question. If it is outside, and have never been painted, you need to prime it with a good block filler, and then paint it with a mid grade to top grade paint., if it has been painted before and is outside, you need to power wash it with a power warsher that has a bleach injector, bleach helps kill the chalk and mold. You can run your hand along the surfice and then look at your hand and if it is chalky looking, then it needs to be powerwashed again. then put a sealer on it, then paint it. this way the paint will not peal. if you paint over a chalky serfice or a moldey serfice it will peal in 2 to 3 months.
Inside, well you cannot really powerwash inside, but you can take a spunge mop and a bucket 1/4 bleach, and 3/4 water and wash most of the chalk off if it is chalky and then seal it with a sealer and then paint it. and again if it has never been painted, use block filler and then paint. I hope this helps

rather vague question but if this is about a cinder block wall then just use a roller with plenty of paint cause you'll lose alot in the holes

lots and lots of paint - it sucks it in and take many coats
call your local home depot or hardware store they have different applications.you may need special products or call a masonery supply store
Paint it with dryloc or a simular expanding paint to fill the cracks and seal out moisture, then paint the dryloc.
If you don't seal out the moisture, any paint you apply will be peeling off in no time.
You could work with what you have. A block wall can be turned into an interesting stone facade. I recently began painting a stone wall in a room of our house for a theme bedroom. Here's a pic: What is the best way to texture drywall?
