Painting the covering walls of your home with a brush or roller can be a fairly time involving job. But with a properly-used spray gun you can soon desist the job.
Although you don't need special paint, you do need precious special equipment: you need a spray gun. Fortunately, these are widely ready at a modest rental from good local tool hire shops. The foremost thing is that you pick the right kind of spraying tool for the paint you wish to use. Choosing the gun can, in fact, be rather complicated - there are so many separate kinds ready - so you could tell the hire shop what you want to spray and leave the decision to them.
Compressor Troubleshooting
The simplest type of spraying tool you are likely to be offered is called an airless spray unit. It is a uncomplicated pump which takes paint from a container (any container will do) and then squirts it out straight through a spray nozzle. It is very sufficient in terms of labor and use of materials and very fast. It is capable of delivering up to 2.25 liters (4 pints) of paint per exiguous (a practiced operator would normally cover about 240sq m/262sq yd in an hour). This type of gun does however, have a few drawbacks. To begin with the paint must be thinned before ii can be Sprayed, which may mean applying an extra coat in order to accomplish the required coverage and color density Also, with the pump at ground level, problems may arise when you are working on structure higher than about two stories. The engine may not be remarkable adequate to pump the paint that distance. In addition, this type of unit will not cope paints containing fillers.
An alternative is a engine that works a bit like an old-fashioned scent spray: the air flow is in case,granted by a compressor which may or may not be rented out as a separate item (if you do have to hire the compressor separately, make sure it is sufficiently remarkable for the application you have in mind). Reaching heights with a engine of this type should not be a problem. The only limitation is the length of the hose between the compressor and the spray gun, but many hire shops contribute 10m (30ft) hoses. A point here: not all compressor-operated units are the same and you should check that you are using a suitable type. At the lowest end of the scale, you'll find small transportable units primarily designed for spraying cars and the like. So long as you use a paint that does not comprise fillers, these can be used to spray walls, but since the integral paint container normally has a capacity of less than a liter (1 pint), you will spend a lot of time running up and down to refill. Larger 'industrial' versions using more remarkable compressors are ready and these are faster and have feed cups of around 1 liter (1 pint). They too will only cope lowly resin- and water-based paints.
If you want to spray on a reinforced paint there are a estimate of options, with separate suppliers calling them by separate names. Those able to cope with most lowly filled covering paints may have a shoulder-carried, or back-pack style, paint container. Those capable of spraying anything from reinforced paint to very heavy, plaster consistency materials tend to be fed from a gravity feed hopper on top of the spray gun, or from a separate pressurized tank.
Whatever you conclude on, do double-check that the gun is suitable for the material you wish to spray; even if the basic tool is right for the job a separate nozzle may be required. Also make sure you get adequate instructions on using and cleaning the tool before you take it home. If you damage it or return it dirty, you may lose some or all of your deposit. Again, bear in mind that some compressors are electric and some petrol driven, but the smaller units are approximately all the time electrically operated (check that you get a 240V model, not a 110V one).
