I've bombed concrete a couple times. i wouldnt consider myself a writer, yet. but i need a tip on bombing brick walls. see im used to concrete which you might have to spray the lines 2wice, usually once. and most of my work is done on paper or canvas with an airbrush. so i was at walmart pickin up a dvd and got a can of paint. behind my apt is an abandoned brick house. it was burned pretty bad, thats why i think its abandoned, and of course kids have vandalized it. but its got a good 25X8 foot brick wall. so i walked over and started to lay down a layer to see how it'd work out. first thing i noticed, the grout would take the paint nicely but the brick soaked it up like paint wasnt even coming out of the can. im sure you all have been there. so in effort of trying to get a good line i had to spray over it like 5 times. i'd get drips like crazy. i've decided im prolly ganna just paint a black square and use other colors ontop of that painted surface. but just out of curiosity, if i were to walk up to a brick wall to do a throw up, how do i get a good line on brick without the drips? this is annoying me really bad. this is the perfect practice spot (no one goes there EVER, big huge wall, 2 min walk away from my house, perfect)
