| 1221701 | 2011-08-08 05:31:00 | Hi All, I've recently discovered that a modest compressor and kit can be had for a couple hundred bucks - which is a fraction of the cost of a few tubs of paint. Now I'm keen to know if these small entry level compressors are adequate for spraying paint, or if it's a false economy and requires a bigger unit to do a decent job. The cheapest I've seen has something like a 20 litre air tank, whereas the bigger models go up to about 45-50 litres. Am I dreaming to think this would make a big pait job easier? Seems the biggest pain is to refil the 1 litre paint tank all the time. |

| 1221702 | 2011-08-08 05:52:00 | Sounds fine to me, you just have to take ut slow so the compressor can keep up with you spraying. Just get a good quality sprayer though! :pf1mobmini: |

| 1221703 | 2011-08-08 05:56:00 | Depends on what you are spraying, as in the amount of consistent pressure you require, type of paint etc. If its something small (area) with a low pressure gun, then they should work fine. I have a small 21 Lt /5HP that is a cheapo, its fine for what I do with it. |

They arnt designed for that sort of constant use Ive also had to replace the drain valve 3 times (only $10 a pop so no biggy) |

For those you need one of those electric units from Mitre 10 etc, they have tungsten tips , so no prob. The best way if you are painting a house or a fence, is to hire an airless unit, as used by pro. |

I’m a bit confused here Paul because you’re going to need paint anyway? :confused: But the bottom line is good spray painting gets down to skill. I’ve seen a car painted with a Vacuum Cleaner spray gun and it was brilliant. Mind you, the guy with the Gun was a Crack spray painter anyway. But it depends what you’re painting and if it’s something like a house you’ll need patience to let the pump build up pressure and give it a rest. The hobby ones are like welders and have a “Duty Cycle”. Having said that if you wish to paint a quarter of a house wall at a time and then stop for a couple of beers then no problem. Oh, and the Compressor and the Gun are two seperate items and one often gets blamed for the others short fall. ;) |

I'm primarily thinking of using it to do a roof - 2 storeys up, so there's some 'sphincter' component to the work along with the sun, heat, tedium of doing the prep and 2 topcoats. Then in years to come there's a hell of a lot of fence to paint. In years gone by I've forced myself through these jobs with brushes / rollers, but now that I'm getting older and my knees are very tender to kneeling for any length of time - it just seems sense to pay for the kit to make life easier for myself... assuming I can do a semi decent job with a sprayer. I'm assuming the job would take a fraction of the time with a sprayer. Bought an airless Wagner many years ago, and it struggled to even suck up the paint, and had enormous spray drift, so am hoping an air sprayer will allow a better job. |

The good compressors use a belt drive normally. |

Well Paul whilst it is perfectly possible to paint a roof and a fence with an entry level spray systems but the reality is they are by no means ideal. With the type of system I think you are talking about the extra Air Hoses to get you onto the roof will probably cost more than the compressor, unless you intend hoisting the compressor onto the roof. There are some good Airless systems around, but at the end of the day it may be more economical to hunt around and find a guy with the good gear that will do it for you at a good price for a “Cashey”. ;) By the way I fully understand what you mean about aging bones when it comes to running around on roofs, especially two stories up ;) |

| 1221710 | 2011-08-08 09:10:00 | I sprayed a fence with an el-cheapo compressor and spray gun. One hell of a lot easier than roller or brush, but you do tend to use more paint. The thing did clog up from time to time, but cleaning it out was easy. One thing you have to be careful of is wind. Don't want specks of paint appearing on your neighbours car... |
