I was contacted today by a contractor who is working on a Dinkin’ Donuts in my area. He is in the process of taking down the store signs and getting ready to repaint. He said he needed someone to power wash the store “sign band” which he says is stucco. I am new to the power washing business and have only done residential jobs up to this point. I have used the search button to try and find my answer to this question but have not found anything definite. I found a prior post that indicated this could be potentially called EIFS siding and that normal sh solution will not work. My question is will my normal house wash mix which is 12.5% sh, water, and eliminator in my 5 gallon bucket take care of this type of building? I am using a 4gpm 4200 psi direct drive with a downstream injector 10:1 from pressuretek. Also, should I quote the entire building of adjust for just doing the “sign board” area arena the building. Thank You.
You did not search hard enough.
Keep looking up info on stucco cleaning
Well my original search I saw everyone saying to use a stronger mix but I guess I was thrown off by the EIFS siding and wasn’t quite sure. I honestly didn’t know EIFS was a thing until today. But anyways, it appears down streaming is not a great method for this so I will be passing until I gain more experience. Also, thanks to everyone for posting on this site and sharing information. It has been a great resource for myself and others when first starting out.
You want a stronger mix than ds can provide for stucco. You’ll need an x jet or 12v pump. If its just a small area a pump sprayer will work. If hes going to paint over it you really don’t need to remove any stains. Just remove cobwebs with a brush. Ds some soap. Rinse all the dirt amd debris off. Call it a day. Send in two quotes. Ome for just the sign area and one for the whole building. Then if youre into also include a quote for the exterior wimdows and the flat work around the building.
Edit: generally ill include a 5-10% discount if they want everything done. Even if its more $ than the client originally intended to spend it helps sell the job if they feel like theyre getting a “deal”.
