The Types of Sprayers

In general, you can find four basic kinds of paint sprayers. They are hand-held cup gun sprayers, airless paint sprayer, air sprayers and high volume low pressure (HVLP) sprayers. Each type is designed to meet different needs of painters.  Cup gun sprayers are usually for beginners because they are easier to use and are perfect for smaller jobs. Since they create a higher quality finish, air sprayers are used for automotive work.

If you want to paint for large areas whether inside or outside, then airless sprayer is the right option for you. However, if you want to minimize the overspray resulting in a cleaner job with less waste, then high-volume low-pressure sprayer is the most effective tools for that. But, these sprayers work best for indoor projects.

Another type is the cup gun paint sprayer which is great as they are easy to operate and are reasonably priced. The price is at about a hundred dollars or less. You can find them easily at hardware and home improvements stores. These sprayers usually hold about one quart of paint making them ideal for small painting jobs around the house.

You can spray your large wall within each minute with multiple guns and hoses that spray over a gallon of paint each minute. Moreover, if you would like to work with stains and lacquers, you can buy sprays with pressure control settings. By this setting, the paint can be sprayed at fan widths from two to twenty-four inches.

Since larger airless sprayer is more expensive than an ordinary airless sprayer, so you better use them for larger projects like painting a basement, and etc. This type of sprayer works faster, about a half-gallon per minute. This makes it great for projects that need to be finished quickly.

However, you can consider using an HVLP sprayer for smooth or mirror-finish look such as trim, cabinets or some furnishings. You can also use conventional air compressor powered sprayers but they may produce too much overspray. This is why, it is important to understand different purposes of sprayers.

Choosing Nozzle Setups for Spray Gun

So, what type of nozzle setups should you use for your spray gun? Actually, you’ll achieve the best results when you refer to the paint manufacturer’s technical data sheets for that particular product you’re spraying. There are many nozzles that you can find, but each nozzle has been prepared to meet the features of the best needle nozzle combination for each product.

A general rule of thumb is:

  • When you use a nozzle size of 1.7 to 2.2, heavy-bodied primers and primer surfaces will work best on it.
  • Basecoats should be sprayed with a 1.4 to 1.6 nozzle.
  • Clear coats should be sprayed with a 1.3 to 1.7 nozzle.
  • Sealers and single-stage urethanes should be sprayed with 1.4 to 1.6 nozzles.

That is the general rule of thumb and many painters choose to go against the norm and are able to produce outstanding results from unorthodox methods.

Generally, you should go down in nozzle size to break the material down into smaller particles to get a smoother finish, when you have a high-solids clear coat or single-stage urethane. You should go down in nozzle size to break the material down into smaller particles to get a smoother finish. However, some spray gun manufacturers have gone against this rule and gone up in size. So, be sure to refer to the gun manufacturer’s recommendation as well as to the recommendation from the paint company.

Primer surfaces will require a much larger fluid nozzle. No material is deposited on the repair area as thick primer surfaces won’t go through a small fluid nozzle. In fact, some painters have complaint that the primer was spraying dry and adhesion was poor. This is because his body work wasn’t being covered and the primer was flaking off, even though he already uses a very high-building product. The reason is because he uses 1.3 fluid nozzles while in reality, he should at least use a 1.7 nozzle. This is what will happen when you don’t study your product very well.

Powerful Painting Tips

Achieving best-looking and durable paint result doesn’t happen overnight. It takes lots of practice, good tools and great painting tips. If you have practiced a lot, and bought good painting tools such as Paint Spray Gun, airless spray gun or paint roller, then it is time for you to get great tips, such as follows:

To get best quality work and no cost consideration, you can combine dirt proof and weather proof 100 per cent acrylic exterior emulsion paint or heritage finish or spectrum finish for external walls, premium emulsion paint for internal walls, melamine or polyurethane finish for woodwork and first quality synthetic enamel for metallic surfaces.

Moreover, you can use textured exterior emulsion paint or semi acrylic emulsion paint or cladding for external walls, low range plastic emulsion for internal walls, low range melamine or polyurethane polish for woodwork and second quality synthetic enamel for metallic surfaces for medium cost and quality.

How Many Spray Guns Do You Need?

Every painter will do their utmost to produce the best paint job possible. Using a new spray gun can be the best way to achieve the most satisfying paint result. In fact, knowing how to use spray gun is the right recipe for an outstanding paint job. So, let’s start from how many spray guns do you need?

What material that you are spraying is important whether your gun is old or new. Since the advent of VOC laws, the material you spray has changed too. So, it’s even more critical to choose the spray gun based on what you’ll spray with it. In fact, some spray guns are clearly designed for some purposes. For example, there are some spray guns designed especially to spray clear coats. Some of them, even especially design for primers and other heavy-bodied materials. Many painters also provide at least three to four spray guns for primers and surfaces. The other is for basecoats and another for clear coats.

Can I use one Spray Gun?

If you cannot afford to have three spray guns, you can try the other way. You should at least have one spray gun for spraying clear coats only. There’s nothing more disconcerting than laying down a beautiful finish. Then, when you start to lay down the final coat of clear, a glob of basecoat comes out and lands right in the middle of the clear. Hence, to prevent this thing happens; you better have a dedicated clear coat gun. Of course, if you don’t clean your gun properly, you can have the same thing happens.

So, this doesn’t mean that you should have 3 spray guns to complete the tasks. In fact, you can finish the painting job with one spray gun only. For instance, you can finish it with a 1.6 nozzle setup and you can spray everything from primer to clear coat out of. However, it does take more time compared to when you have more spray guns. This is because you have to clean the gun before spraying a different material.

What is Coating Thickness Gauges?

Coating thickness gauges is PCE instruments that can determine the thickness of different layers of corrosion and variable layers. The coating thickness gauges can be used on all surfaces of metallic materials (metal, iron, nonferrous metal alloys). The coating thickness gauge uses magnetic induction or by means of analyzing an eddy current as measuring principles. It is very useful for most surfaces as the devices work non-destructive. Hence, materials have to be used afterwards. Therefore, these devices cannot miss a place where galvanizing processes are carried out. This work is perfectly suitable for quality control and other different production purposes in the process of anodizing, or galvanizing.

This thickness gauge can also determine the degree of hardness by means of plastic, glass and metal walls and windows. Usually, this equipment can be used with a head unit to test temperatures up to 300 C. You are also able to check the thickness of the wall for steam pipes and also other pressure pipes. Before starting measuring, you need to add gel on the sensor and the object that you want to be measured. Then, adjust the sound speed and the unit will display the thickness of the measured object. Each device has a different memory capacity to store a minimum of 10 measured values. Coating thickness gauge is usually designed for easy handling.

These devices are essential to measure the coatings in the automotive sector but also and also many more, for example:

– F Model: to measure lacquers, paints, plasters, etc. on iron and steel
–  N model: to measure lacquers, paints, plasters, etc. on non-ferrous metals (e.g. aluminum)
– FN model: (coating thickness gauges combined for ferrous and nonferrous substrates)
–    PT -200 Model : for layers / painting, and any other non-metallic coating bases

Each brand of coating thickness gauges will offer you with different specification. So figure out which one that will suit you best.

How to Paint a Stairway

Do you know that painting a stairway is different than painting the average room? In stairway painting, there are more things to consider, such as the risers, height, and hard to reach areas.
