With the paint sprayer help, you can easily apply the gallons in LESSER TIME than any other way of painting.
And secondly, it helps in giving a SMOOTH FINISH to ANY SURFACE, wooden or glass doors, etc.
The central working principle of a Paint sprayer starts with pumping paint with high pressure at 3000 psi. Then through the hose of the sprayer and with the small hole on the sprayer gun’s hose.
They design the tip of the sprayer can emit paint in a circular. It’s like the shape of a fan allowing small droplets of paint reach the surface. Various types of tips to facilitate DIFFERENT TYPES OF PAINT like lacquer or stain, varnish, latex or house paint.
These advantages make it suitable for big projects of painting like painting a new building or a 200 ft fence for privacy.
Along with advantages, everything has disadvantages too. And I have told you about the benefits of the paint spraying before, and now we are going to talk about the problems of this style of painting.
One of the cons of air spraying is that the particles of spray don’t stick entirely to article’s surface and the second one that the paint with air sprayer resides in the air in a significant amount and gets settled at any nearby place or object, which is wasting 20-30% of the paint.
So while painting with an air sprayer, we have to make sure we have covered the areas nearby to avoid any paint on them. Painting the outdoors of any premises is also a disadvantage as you might be painting your shrubs, roof or your neighbor’s car due to over spraying and wind drifting it to random places.
Another disadvantage is the wastage of time used in cleaning the sprayer and flushing paint through the hose and the pump. And, if you are having your own and using that spray gun rather than a rented one than you have to do the filter cleaning. Specially install the fluid storage tank. If you are using oil based products than you must have to reuse or store liters or gallons of the used solvent left after the process of cleaning.
According to me the disadvantages are less than the advantages as an airless sprayer can help you in saving big time, and work out the big painting jobs and it also helps in providing a finish to the paint that any brush could not offer.
Buying or Renting? What to Choose?

But renting is also a great option as it helps in deducting the cost of buying a $200 sprayer and renting the sprayer whenever it is required, and you don’t even need to clean the filters, and you can easily avoid the maintenance charges. Renting charges for the sprayer are estimated at around $70-$80 per day.
