hey all i hope maybe some of you can help me out.

recently started my own buisness as a handyman kind of thing, so please excuse my ignorance, although i did use the search option and have visited many web pages refered from there im still not positive what i need.

ok here is the deal i landed this contract to repaint a apartment complex consisting of 13 buildings. the buildings are located in central florida about 2 blocks from the ocean.

i purchased 2 dewalt power washers rated at 3750 psi. ( sorry i do not know the gpm ) to do the cleaning before prep and paint.

the problem ..... they are great machines ( though they like to drink gas like its happy hour) i have a 4 man crew 2 per machine so they dont rest when in use.

anyway these buildings were built in 1968 and have never been realy touched since.

okay okay to the point .sorry im long in th tooth.

using the machines i have and using the 40 deg tip supplied , seems to get most of the ie: dirt. the problem is the peeling paint and the more i do the more concern i am having

when i hit a "pocket" were 40 tip peals the paint i switch tips as far down to the zero deg tip which is fine but know the other problem.

one is a zero tip takes forever to clean a wall aand the other is that is a stucco finish and if you get to close you start carving out the stucco. (again these are old buildings and the stucco is old and failing to some degree)

so what to do... i have reaserched different tips and from what ive have found i think i might buy a suttner turbo spray nozzel.

the size of the pattern concerns me though.

these are big buildings and time is is money but i want to do it right

but i dont want to carve the heck out of the building which i hve to fix before repainting.

using pool grade chlorine were needed ( sodium hypochlorite @ 10.5 % for 2.5 gal)

this is put on manualy using a hand sprayer.

Its probably to late for advice, but if your looking for a quality paint job as far as longevity goes your gonna have to get rid of all the pockets of loose paint and work back to a solid/stable surface which means your probably gonna have to break out the scrapers and putty knives if your blasting the stucco away with the washers.
Sounds like a job I just came across where the previous contractor didn't bother removing ALL the loose paint (only removed what he could spray off) now a year later his work looks just like the the building before he repainted it. People like that keep me in business:D Good luck

variable speed nozzle

as far as the painting and stucco go i don't have a clue but a good variable speed nozzle is what work best for me will save lots of time changing tips but you might have a slight loss in pressure but its worth it

Next time think about a sub to clean before you paint. Some one could have both units done in a half day or so, and you could have been on your way painting with out all the mess ITS ALL IN THE PRICE..
