How to choose an airless paint sprayer
First of all, we need to understand why to use an airless paint sprayer, what advantages does a paint sprayer offer contractors and what size of airless sprayer is suitable for each average contracting job.
Minimal material waste is probably one of the most important facts of using an airless paint sprayer. In most cases and especially on a heavy duty airless paint sprayer, you will find a double method of material suction, so for example when spraying paint you can use a suction hose and with thicker materials you would work with a direct immerse pump. With these material input methods and the atomization procedure, you have already gained material therefor money.
Airless paint sprayers offer faster coverage than a roller or a brush application. With a sprayer it is easier to apply paint to a large variety of surfaces (walls, ceilings, indoor – external coatings, floors etc.) By adding accessories to your sprayer, you can reach high and inaccessible surfaces, increasing your productivity and saving time & cost.
Airless sprayers have a paint pump that pushes the material into a paint hose and out from a spray gun, at the output of the airless spray gun you will find a guard and a spray tip. The spray tips come in a large variety of sizes depending of the application and the desired fan pattern.
So now we have seen some basic facts of airless paint sprayers, we need to ask ourselves what size of sprayer fits my average coating job needs.
A few important questions are:
- Power = HP ?
Professional airless paint sprayer may be found either with electric motors or gas powered engines. So know the job site power source or you can always choose a convertible power airless sprayer.
- Average project size?
Think about your average jobs that you take on or bid, you don’t want to land up with a small unit that will limit your coating operation. If you most commonly work with commercial coatings and larger surfaces then a larger heavy duty airless sprayer may be appropriate for you. On the other hand if in average your painting jobs are small or housing renovations then a less powerful sprayer is probably ideal for you.
- What materials to you apply?
A large variety of materials may be sprayed with airless sprayers; therefor you need to be sure that the working pressure of your sprayer is appropriate for the material. For example if you are spraying heavy texture then you definitely need a high-pressure airless sprayer, always consult your material supplier of the psi / bar needed to spray the material.
- Volume of coating - pricing
Once again, when purchasing a paint sprayer you must take into consideration the payback time of this investment, you don’t want to land up spending more than you can afford.
- Number of spray guns?
How many users / how many simultaneously spraying? Heavy duty airless sprayers give you the opportunity to have multiple users spraying in order to get larger jobs done faster. Keep in mind that some spraying equipment can handle only one spray gun. This always depends on the contractor’s requirement per average jobs and time schedule.
