First thing first…

Prior Arrangements: You should make sure that you properly check that the wall you are about to paint is in good condition; you check for cracks and peels on the various surfaces of the wall before you go ahead and apply fresh paint over them. It is best that you paint at a time when the weather is dry because if you go on to paint in a humid environment, your paint will slowly dry up, and you would have to recoat every time. So, make sure that the weather is dry when you are about to paint, as this will make your job easier.

Your Painting Accessories: Before you start off with painting whatever surface, you should make sure that you have the right tools that you will need to see that you get your painting done, and done right; these tools are your HVLP paint sprayers and the other accessories that come with it, unless you want to do your painting by hand, that is, then you would need a paint brush, but why stress yourself? To make sure that you reduce the occurrence of drips and blurs, you would need to get a high-quality painter’s tape. And for a brilliant coverage, you should get the proper kind of HVLP paint sprayers that will enable you paint using different patterns (vertically, horizontally, and in circular patterns).

Pay Attention to Holes and Coverage: While you paint, make sure that you pay very close attention to whatever crevices that might be in the wall you are paint, and you should make sure to spray those well, so that you get an even result.

Shield the Area: You should make sure that you cover any area that you know that you will not painting, like using outlet covers, light switches, hardware, furniture, doorknobs, and so forth. Why this is important is just so you can save yourself the stress of having to clean up the mess in case paint falls on any of these, you would find yourself cleaning these up, when you should be resting.

The Primer: The primer plays a very vital role when you are painting. It gives an alluring look to your walls. If you happen to be working on a smooth surface, then mixing your paint and a primer would work excellently.

DIFFERENCE BETWEEN AN HVLP PAINT SPRAYER AND AN AIRLESS SPRAYER

We have two types of sprayers that are used for architectural spraying, and they are the airless sprayers and HVLP (stands for High Volume, Low Volume) sprayers. There is another type of sprayer, though, and this is the conventional type, which is the compress air sprayer, but it is never used when painting a house. This is because the compressed air sprayers tend to give too much overspray, and it does not spray the standard house paints well enough.

What are the differences?

The Airless Sprayer

This is a high production sprayer that shoots paint out of a small opening or orifice in the tip of the spray gun, and this helps to break up the paint into particles, spraying them into patterns. In this kind of sprayer, air is not used, hence its name, airless, so as to aid the break up process of the paint.

Airless sprayers make the breaking up of the paint into particles faster and better. For latex paint, they spray very well with the airless spraying unit, and they usually do not even need to be thinned at all. And this is the benefit of the airless sprayer, your ability to spray the heavily bodied materials without your having to thin them.

They spray paint at a pretty good pace, from .33 gallons per minute to 1 gallon per minute or more.

The HVLP Sprayer

This paint spraying is considered an “air gun” that uses air in the optimization of the break up of paint into small particles, and it does not do well in spraying heavier materials like latex, just like the airless sprayer does. The HVLP sprayer does give you a fine finish, and it works well with oil (alkyds) enamels, varnishes and thin viscosity paints like lacquer and shellac.

The rate of production of the HVLP sprayer is far less than that of the airless sprayer, and this makes it better used on trim and doors and not on walls and ceilings. HVLP sprayers are known for their ability to reduce overspray when using them, this means that they create less overspray than the convention spray system, like them air compressor sprayer, and also even less than the airless sprayer.

One way to achieve this less overspray when using the HVLP sprayer is to keep the air volume at a minimum so that it does the job required, giving you the result you want. You can also keep the fan down as this helps to reduce overspray.

ADVANTAGES OF USING THE HVLP SPRAY GUN

Using the BEST HVLP PAINT SPRAYERS spray gun has a lot of advantages, below are a few:

  1. It is fast: HVLP spray guns tend to cover more surface areas in less time than the other painting methods.
  2. Money-Saving: HVLP spray guns ensure that most of the paint gets on the surface you’re painting and not in the air, therefore reducing the chances of you having to buying extra paint.
  3. Environmentally Friendly: Using the HVLP spray gun ensures that you reduce the level of air pollution that other painting methods tend to cause, because HVLP spray guns reduce the amount of paint that goes into the atmosphere.
  4. It is Precise: HVLP spray guns sees to it that you have a more finessed painting, with an even lesser overspray, giving you accurate and desired results.
  5. It is Healthier: The HVLP spray guns have lower levels of Volatile Organic Compounds (VOCs), which is quite healthy for both workers and those living around the area where the paint job is being done.
  6. It is versatile: This method of painting actually sprays more than it paints. It can be used for primer, contact adhesives, lacquer, varnish, metallic coatings, vinyl fluids, and so forth.
  7. It is convenient: They are lightweight, portable, and compact, making on-site painting an easy task.

Things to do When Using the HVLP Spray Gun

The tips below will show you ways you can best use the HVLP spray gun.

  1. Ensure that you move the sprayer evenly, in an elliptical shape while you paint.
  2. Make sure you mix the correct amount of both air and paint. If there is less air, there will be poor coverage and the paint durability. And having too much air present will only cause the spray gun to blow the paint everywhere, and not focusing on the surface you intend painting.
  3. You would need to add some thinner to the paint since the warm air that is created by the turbine of the HVLP dry the paint, giving you an uneven finish.
  4. Never use halogenated hydrocarbon solvents in your HVLP paint spraying unit. And you should also never have cleaning agents like trichloroethane or methylene chloride through an HVLP paint sprayer unit.
  5. If handled by an amateur, the HVLP spray gun will not produced the desired results. Make sure that you make a professional handle the painting.

Following the guideline above will help you optimize your HVLP spray gun.
