Prep for painting

Hi guys,
Thanks ahead of time for the suggestions. I’m being called back to a job that earlier this year I turned down but they liked the previous job I did washing their steeple. There are huge old columns at the entrance to the church and they want me to prep for painting. They were not sure whether or not they wanted me to remove as much paint as possible or if I needed to just knock the loose paint off.
Any input on what is necessary is appreciated.
I have used F8 and 18 in the past. Is this the best way about going about it?

Got pictures?

I wouldn’t offer to remove paint. If it’s older than 1975 then there may be lead paint behind it also


I don’t but they are 30-40’ columns that look like they have a few coats of paint on them. If all that’s needed is cleaning and knocking the chipped paint off is necessary then I don’t want to do overkill and charge a good client for something they don’t need.

I’ve done a lot of jobs where customers want something prepped for paint. I always tell them that I will remove all of the paint that is flaking and the painter can get the remaining with scraper etc. No need to take off paint that is still stuck on good. I also spray my HW mix on as well that way it will be cleaned and my shooter tips seems to work the best with the flaking. To me water volume flakes off paint better than Pressure.


A good painter will probably scrape it anyway even if you blow the paint off. If the wood behind even the good paint gets wet from the wash it will eventually start to flake. I’m no painter, nor do I claim to be, but I prep for a few around town and they say the killing of the mold is the most important part. Scraping and sanding and cleaning up that mess is a part of their quote.
