Brick sign cleaning questions

[Reider]

I have a customer that wants 2 entrance signs washed for their neighborhood. As you can see from the pics, there is some heavy growth in the brick. What solution would you tackle this job with? Low pressure or soft washing? I'm leery of using pressure because of potentially damaging the brick/mortar.


I've never done signs before, so I'm also wondering what price range some of you would be at? Each sign is 30 ft long and up to 4 ft high, with both sides being cleaned.

We just pressure cleaned for a Hoa master association 18 about the same size friday. we sprayed with roof pump about 50/50 mix then washed with about 1000 psi. make sure you wet the plants before and after.

Good Advise Greg, use a variable wand to lower and raise psi. With Un-glazed brick you've got to careful, high psi can etch it.

How do you get the mortar cleaned from those black streaks if you can't directly hit it? I have a church with 40' walls and goes down a steep hill. I can't get close enough to hit with any pressure just wet. I tried straight 12 1/2% down streamed 10:1 but they won't budge.

Lower your pressure

Don't forget that you can lower your pressure without messing with the machine. Just switch tips. If you're using 4 gpm, snap in an 8 gpm tip. 5.5 gpm, 10 gpm...etc. This lowers the pressure considerably, and you don't have to mess with the machines. When you want the higher pressure just put the regular tip back in. We do a lot of coquina here in fla. and the bigger tips come in handy when we rinse it.

Thanks for the advice. Nice work on the signs Greg and T-Mac.

You can do those with softwash in 30 min. If you are dealing with an influential HOA Prez then you might consider donating the service in lieu of referrals. Call the prez once a month and ask for referrals. You will get more work if you keep at it.

Good advice George. Thanks.
