Hiya Ken,

New concrete needs to set at least 30 days before painting - you're probably
Ok on the block itself, but the mortar would still be too green before that amount of time has passed. Obviously before painting, you're gonna want to make sure the block is clean and free of dirt, loose mortar or any traces of efflorescence. It's always a good idea to apply 1 coat of block filler before finishing, and for best results, finish with a high quality acrylic finish...

...and not that it really changes anything in terms of time and prep, but is this for an interior or exterior app?
