New to the forum and wanted to see if you guys can help me with the proper mix for removing mold-mildew from a retaining wall. I have Sodium Hypochlorite and elemonator on hand, what ratio would you recommend?
You could probably just hit it with a turbo nozzle. You can try and pre-treat with about 4% if you want. You might not need to though.
Welcome to the forum. There’s a lot of great info on here. There’s a search icon in the upper right side of the screen. You can find the answers to most questions you have.
Ok, I’ll try that. I appreciate the feedback. Looking forward to being a part of the forum. Thanks again
As its painted, I wouldn’t turbo nozzle it personally.
I’d walk it with a pump spray, 50/50 SH and surfactant.
By the time you’ve got your pressure washer set up, it will come off nicely with the white fan tip 40°.
I didn’t even notice the paint so good call there Steve.
Make sure you know what the customer wants and set expectations. Is this a paint prep or do they just want the mildew off?
I was actually going to do that but the plastic connector on my pump sprayer broke so I just used the soap nozzle with white tip. I let it set for about 15 minutes then washed. It’s actually my property, wanted to try it here first.
It looks better but you would probably achieve much better results with a direct application like the other folks mentioned. Pump sprayers are cheap enough to keep 3 or 4 around all the time. You’ll enjoy not having to worry about what was mixed in your pump sprayer before mixing up something else and causing problems. I label mine for SH, OA, EBC, etc. Try to get ones with the good seals.
Yeah that’s a good idea. Appreciate all the feedback. Thanks guys…
