  1. This is what one of the local manufacturers told me
  2. The final rinse is what really makes it, often requires a couple of go's as the silt on the surface, fine sand used for grip & oxidised paint will build up against the hose and only be visible when dry Excellent job Rob Drainage and the size of the out of play area can take or add quite a bit of time... as can the amount of mould & dirt. I allow about 4 hours and 5 drums of SH for an average court, but my machine is only 7gpm. A lot of "cleaners" around here, and this is probably why you lost the job, can be cheap because they just use high pressure with no cleaning/mould killing products. As for my price.... my market is not yours, and my $ is not your $ either (I'm in Australia) so you'll have to work off your hourly rate + consumables etc Cheers
  3. Hi Rob Bleach is your friend as most of the problem is mould - If very dirty I'll use a strong mix (about 6%), if not I'll start at about 3%. Your s/cleaner needs to be between 1000 & max of 1500psi - don't be afraid of the overlap. Then rinse a lot, sometimes twice to get rid of all the dirt & paint (I use a 2540 at 7gpm) https://youtu.be/Dn73yq9V0-c sorry about the link, I can't remember how to embed - i really need to get back here more often
  4. Cheers, that's great news. John
  5. G'day Chris, thanks for the lead on a good 12v pump. How well does the Santoprene diaphragm last (as opposed to the viton that some other suppliers offer)? Northern Tool told a customer None of our NorthStar pumps will be rated for use with chlorine based chemicals. by NorthstarExpert29 November 30, 2012 Will daily flushing allow it to last? Cheers John
  6. G'day Austin That looks pretty good to me, especially for 5+ years of oil. Plus it will look better when dry. Concrete is like a sponge, it allows the oil to seep deep into the pores, while some of the contaminants in the oil sit near the top Cleaning, in particular oil stains, is a combination of 1. chemical, 2. time, 3. temperature & 4. agitation. You need to to know those 4 variables and adjust accordingly. Oil stains in concrete can need more time (to allow the detergents to break the oil droplets apart and allow them to float to the top - remember, oil naturally floats on water), but time you usually don't have. To compensate, more temperature or better detergents can be used. If you want to have another go at it (consider it "professional development"), leave it a week to dry and for the oil to work it's way back to the top (capillary action), then scrub degreaser (take a selection to try) into the stains and keep it wet for as long as possible. When you're bored with the scrubbing and the business wants their carpark back then re clean with the s/cleaner and hot water. Cheers John
  7. While my business pays me a salary, I always compare the hourly rate I get paid to the hourly rate I would need to pay some other employee, and the hourly rate I could be getting elsewhere. But charge-out rate is something completely different, and not something an "employee" would easily understand. My business model works on me being paid by the business for 52 weeks a year for 40 hours a week (2200 hours a year), but I can only charge out about 1200 hours a year (my business is just me, so I need to include running the business and maintaining the equipment etc, as well as doing the work) so, my charge-out rate for a 2 hour house wash (which has a free on-site quote and travel time to cover) looks obscene to the person packing shelves at the supermarket, or selling white goods in a warehouse. But so would their own charge-out rate. While most other home service trades (painters, plumbers, carpenters, electricians, interior cleaners) in my area do give an hourly rate, or piece rate, a competitive and open market ensures that there is very little difference between charge out rates. Of course, this says nothing about their quality or efficiency. :onthego: John
  8. Wax, now that's a nice & cheap idea. I was actually back there last week for some other work and they have been graffiti free for 2 sets of school holidays now... John
  9. Thanks Shane.
  10. G'day Brad Oh, and the customer does not want a glossy finish on the concrete. My first thought is that you need to clarify with the customer what they really want - performance characteristics will determine the type of product. Do they want a topical/surface coating - usually glossy to satin finish (clear or coloured), which, as you mentioned needs regular re-coating and stripping if it is left too long, OR would a penetrating sealer (silicone based) be better - looks invisible, not quite as water/stain resistant, lasts a lot longer and easier to re-coat, - water resistance can be improved with a concrete densifier applied first. As for idiot proof - I prefer the water based penetrating sealers, spray on 2 coats wet on wet, then ready to use when dry. Not being local to you I can't help with particular brands. Good luck with this. John
  11. Some email correspondence Hi John Thank you for getting back to me so quickly with your quote for this work. I forwarded it to the Committee who have asked me to follow up with you a couple of questions: · Does this quote include the back fence and if it doesn’t, how much extra would that be? · What is your hourly rate? Thanks for your help with these. My reply Sorry, I thought (from memory) the back fence was timber so didn’t include it, but I’ll do it for nothing. I don’t usually discuss my hourly rate as comparing rates between contractors is very difficult. The charge out rate is dependent upon many things including the quality and efficiency of the equipment and techniques used. I never discuss my hourly charge out rate as (particularly) domestic clients want to compare it to their own pay rate, I'm even cautious with other building and home service contractors as this business requires on-site "free" quotes and my average job would be only 3 hours, while most others are the opposite. PS. I didn't get the job. Can't will then all, especially with committees.
  12. Brilliant work. That F9 looks awesome. All I can get over here is ol' faithful - oxalic and hope. John
  13. G'day AP Do you have "confined space" regulations in you state/county? as these may dictate the type of access required - possibly a tripod to hang a rope and harness from. The concrete can be sealed with a concrete densifier such as this http://www.con-treat.com.au/densi-crete.html, it's a "colloidal silicate" that penetrates the concrete and reacts with the minerals to form a gel that fills in the air gaps. This type of product is much easier to apply than topical coatings. Always great to see the interesting jobs! John
