I was finaly able to upload some pics. This is the front and one back shot.

Thanks for the reasurance of my price range. I figured $100 for the concrete, $45 for the deck (PW only - no garantee of non-feathering without brightner $60-$120 for brightner and sealer) and $230 for just the siding. $416.17 with tax. I will probably hit the windows and gutters but no ladder and no scrubbing. M5 with 10.5% Sodium Hypochlorite, Cascade, and Dawn. Maybe a little liquide clothes washing soap. I figure with a 2.5 GPM low pressure system I can do the job in 4-5 hours. Thats still in my $55/hr range.

This is the info I needed. I actually cut of the diverter on the end of the sprayers wand and it was spraying a good quantity. I think I will make one also. They come in handy.

I tried using a garden pump up sprayer but it definitely does not put out the chem like a shurflo. It just mists the roof and no matter what chem. it never works like some of your pics. Until my M5 shows up is there a "best" type of pump up sprayer?

Ryan H, Are these pics taken after applied chem with a shuflo? - No direct 45 degree spraying, etc.

I was called out to a ladies house that had a stain on her drive. When I got there I found out that another guy had tried to get the stain out but could not. I used a 12:1 concrete cleaner soln from Northern and deck brushed it. Nothing. The drive was concrete but not all smooth. It had a border of smooth concrete but the inside of each panel was rough in one direction. It looked very pourous. I washed down the drive and set up my pressure washer. I poured a more concentrated soln. on teh stains, scrubed and then hit it with a 45 degree at 2.5 gpm 280 psi. As soon as I started to move the chemical I noticed that wherever the chemical was - was now orange. The more I looked at the rest of the drive the more i noticed that every little scratch went through the top layer of the concrete and exposed the orange concrete below. It appears as though the top layer of the concrete was just a very thin layer of white. This is a new subdivision and she is one of four that have moved in on her street. Her homeowners association was on her case to get the stain removed. Now they are going to be going crazy over these larger orange stains. Is there a way to repair this - new concrete layer, solid color spray sealer...

This is the result after using the concrete cleaner from Northern at 12:1, then full strength. I think the cleaner went right past the thin surface of the concrete in less than 30 seconds. Now I need to figure out if it can be fixed.

I think it was very poor quality concrete. Every scrape made previously by the customer went down to an orange colored substrate. It was almost as if the white concrete surface was painted on. Once the chemical and PW hit it there was nothing left of the surface color. With such a low psi it should not have damaged the surface. My only concern was the concrete cleaner from Northern.

The pics are at ***. I could not upload here???http://www.pressurewashinginstitute.com/board/upload/showthread.php?p=39691#post39691

Looks like Kaui - Point at Poi pu - nice little cafe on the water... Hope you had a great time.

I have a roof cleaning job tomorrow. Spoke to thecustomer and he said that a pressure washer co. came out and cleaned the roofs on two of his neighbors homes and wanted me to do the same. I explained to him that I was going to propell chemical onto his roof, let it dwell for about 20 min, then rinse. He then began to tell me how the "Other guy" did it. He said the other guy was walking on the roof without a harness (VERY steep pitch), and spraying chemical from a bucket on the ground. He said the pressure washer was spraying th eroof so hard he could barely hold on to the gun. My understanding is that you do not agitate the asphalt shingles with a broom or hard pressure beacuse it knocks off the granuals that protect the roof and that help inhibit fungus growth. To my way of thinking the life expectancy of these other two roofs was just cut in half. They do look brand new...for now...

When making the move to a trailer what do most of you use & why? (Truck or Van)?

What about a box truck? We used them at a previous job. We ran electrical to the back for a small mobile work shop, we had a heater for jobs up north, It was a huge mobile billboard, and the box was secure with no windows. If I'm going to spend the money for the long haul I want to make the most efficient decision.

Lord knows we need our trucks for the snow... I think we had all of 5 min. of it last winter and then it was back to shorts & T-shirts on Christmas day. I thought about a truck for the construction cleans. Some of the work sites have mud, large pot holes, or very fine sandy dirt. I don't think a van would have the same traction in these cases. I just though about the security of a van and the advertising possibilities of the side panels.

PW inside of a garage sounds a little frightening. I have a customer that wants to have his driveway, sidewalk, curbs, back porch, around the pool (brick pavers), the hardy plank on his garage (3 sides) and the intrior concrete of his garage done. What would you quote for a job like this? I will have to buy plastic to cover things in the garage etc., plus a degreaser for the concrete. It sounds like a 4-5 hour job.

Any suggestions or tips on buying a new rig? Looking to spen 5-10,000. I know that I want it heated, over 4 gpm, two sprayers, and already on a trailer not just on a skid. I am adding a sureflow and an xjet.

The garage is a two car garage with the two inch lip arond the edge. I will tarp the walk inside on three sides. The only thing on the floor that might be a problem was a 2' area with some paint sploches. He decided not to PW the exterior of the garage, but.... I will also be PW a 48'x 8 brick wall, a 15' fence both sides, and then they want to seal the wood fence, and stain a concrete patio. He wants itemized bid for each item so he can pick and choose. I will probably give him a discounted rate if he does all of it. I figure $450 for all of the PW, then $110 for the staining and painting to be done on another day. Drive - two cars wide - Two cars long Garage - two cars wide Pool deck is aggregate - 40x40 area with kidney shaped pool - 2'walk around small patio - 288 sq ft walkway - 25' curbs - aprox 160' Brick wall - 48x8 I have pics but can't seem to attach or paste...

What would you bid on a job like this? What chemicals would you use?

When stripping a deck I assume you low pressure apply the stripper, let it dwell, then pressure wash it, or do you need to manually scrub? Where are you guys getting the EFC-38? When you talk about a neutralization process, are you talking about a neutralizer like you would use in stripping floors or just flooding with water?
