Why Use a Tip Extension?

 

WHY USE A TIP EXTENSION?

Use tip extension for extra reach! Using the extensions make working with Airless paint sprayers more efficient, by increasing the working radius. The nozzle extensions are also useful for accessing hard-to-reach areas such as ceilings, door and window frames.

 

 

Whether it be for a DIY or Professional Wagner Sprayer, a tip extension is a handy addition to your sprayer. Depending on the project, there are matching extensions between 30 and 60 cm. The use of a nozzle extension often means that the use of ladders or scaffolding can be reduced to a minimum. The Airless nozzle extensions are compatible with all WAGNER Airless guns and are available with a G or F thread.

The reduction of fatigue on the body allows you to spray on a roof without the need to bend to even spraying ceilings, cornices or the hard to reach areas and enables you the painter to reduce the amount of time and money in your spraying application with less setup time.

Below we’ve prepared a list of tip extensions products from both DIY to Professional product ranges to help guide you.

Importance of Paint Viscosity

Achieving a successful and efficient spraying application requires understanding the role of paint viscosity. Viscosity refers to the thickness or consistency of the paint, which directly impacts the flow and atomisation of the paint particles during spraying. 

The viscosity of the paint affects the size and distribution of the paint particles when sprayed. Thicker paints with higher viscosity may not atomise properly, resulting in larger, uneven droplets. This can lead to an inconsistent spray pattern, poor coverage, and potential issues like orange peel texture. To ensure proper atomisation, the paint needs to be thinned to break down into smaller particles for a finer spray pattern and smoother finish. 

Paint viscosity affects the amount of overspray generated during spraying. Thicker paints with higher viscosity may result in excessive overspray. To reduce overspray, better control, and minimise paint wastage, thinning the paint to the appropriate viscosity is necessary. 

The paint viscosity also influences the spray pattern and coverage achieved during application. Thicker paints tend to create a narrower spray pattern and may not cover the surface evenly. Thinning the paint to the correct viscosity allows for a wider and more even spray pattern, ensuring better coverage. 

Why is paint viscosity important?

Different types of spray guns and nozzles require specific paint viscosity. If the paint is too thick, it may clog the equipment, affecting the spray pattern and performance. On the other hand, if the paint is too thin, it may not provide adequate coverage or may cause excessive dripping. The viscosity of the paint can also impact the drying time after spraying. Thicker paints with higher viscosity may take longer to dry, potentially leading to issues like dust or debris settling on the wet surface. Thinning the paint to the appropriate viscosity allows for faster drying, reducing the chances of surface imperfections. 

 

To achieve the desired viscosity for spraying application and a professional-quality finish, it is crucial to follow the manufacturer’s guidelines and recommendations for thinning agents or additives.

The advantages of Spraying Ceilings

THE ADVANTAGES OF SPRAYING CEILINGS AS A PAINT PROFESSIONAL.

Painting a ceiling is incredibly hard work: you get little drops of paint in your eyes, your neck hurts and after a while your arms start to ache especially when your using a roller or brush. 

Using an airless sprayer to spray paint the ceiling makes your job easier – it’s not just quicker, it’s almost effortless. You save time, energy and material – and therefore money!

When it comes to spray painting ceilings, it is usually a case of needing to coat a ceiling in a house or an office building with ceiling paints. This is by far the most common application.

For industrial surfaces, materials with special properties are often chosen for the coating. For example, car park ceilings need to have a particularly resistant paint and finish. In industrial buildings, such as production areas, a sound-absorbing acoustic coating or fire protection might be required.

Coffered ceilings with wood panelling as well as ceiling mouldings also require coating. 
When it comes to wood, you might decide to 
paint or varnish the ceiling – you can get the job done easily with one of the airless sprayers.  

In general, you should try to apply as little pressure as possible to these types of ceilings, including ceilings mouldings. This is where accessories can help, for example, a TempSpray heated hose to reduce the viscosity of the paint or a HEA ProTip low-pressure nozzle .

What are the advantages of spraying ceilings?

Saves you time

Spraying a surface is clearly a lot quicker than painting with a roller or brush – even accounting for cleaning time!

Saves you energy

It’s tiring holding a roller on the end of a long handle over your head and trying to maintain a constant pressure. With the spray gun, you only need to pull the trigger and then move around at a steady pace.

Surface structure is preserved

If you have a ceiling with a decorative or embossed surface, then spraying the ceiling helps to apply the paint evenly. The structure remains unchanged – in contrast to painting with a roller and brush where paint collects in the recesses of the embossed surface.

Saves you material

Just think how much paint is lost through paint splatters and splashes! The spray method doesn't just stop this wastage, it also saves material because it allows you to achieve an even coverage straightaway. With the right settings and a HEA ProTip the overspray is minimal.

Saves you money

If you get the job done quicker and use less material, that means you save money and can start to tackle new projects in the time you have freed up – or alternatively finish earlier in the day

Five simple steps to spraying ceilings

Step 1
- Preparation & Masking

First, the surfaces need to be prepared by sanding or cleaning as necessary. When preparing the ceiling, mask off other areas. Protect the walls and the floor using drop sheets or plastic. Take particular care with walls that are a different colour, ensure that the masking tape is pressed down well to create a straight edge.

Step 2
- Setup Sprayer

Fit your airless sprayer with the required accessories – a nozzle extension or long-reach gun. With the nozzle extension and the long-reach gun you can reach high ceilings easily, such as those frequently found in older buildings. Different versions are available so that you can select the appropriate extension for the size and height of the room.

You will also need the right nozzle and gun filter insert for the material that you are using.

Step 3
- Adjust your sprayer

You can now adjust the material pressure and the spray jet to suit the coating material. Before spraying the ceiling, quickly test the spray jet on a piece of cardboard.

 

Step 4
- Spray Time

Spray paint the ceiling using the same technique that you use for walls: maintain a constant distance and angle as well as a constant speed. If you take a break, cover the container with a lid or cling film so that nothing dries out!

Step 5
- Clean up time

First, remove the nozzle and holder. Let the leftover material run back into the bucket. Then use the cleaning solution and rinse out the device. 

Continue to clean until the cleaning solution runs clear. The gun can generally be disassembled into its separate parts so that you can clean the filter easily and thoroughly. 

For contactless nozzle cleaning, you can use Wagner’s Tip Clean.

What is HEA?

What is HEA?

HEA is an abbreviation of High-Efficiency Airless, the innovative nozzle technology revolutionising airless spraying. Using HEA tips can reduce the pressure of the spray device, allowing it to work in the low-pressure range of 1160-2030 psi. These tips are compatible with all TradeTip 3 tip holders and WAGNER devices. 

How does spraying with airless work?

Our cutting-edge HEA tip technology is the ultimate solution for achieving outstanding results while spraying materials. By utilising a Pre-Tip in tandem with an atomisation tip (Finish-Tip), our technology ensures that the material is atomised at the same volume and speed as traditional airless devices, producing a soft and feathered spray pattern. This pattern guarantees better coverage of overlapping strokes, reduces paint build-up at the beginning and end of each pass and delivers a superior-quality surface. With our HEA tips, you can achieve perfect results effortlessly and save on materials at the same time.

LESS OVERSPRAY

The lower spraying pressure reduces overspray by up to 55%.

MAXIMUM CONTROL

The gently feathered spray pattern ensures better coverage and avoids hard edges.

LONG SERVICE LIFE

Reduced strain on the sprayer and its components mean HEA tips can be used for twice as long as conventional airless tips.

FATIGUE-FREE WORK

Low pressure spraying ensures low gun recoil for ease of use.

SURFACE QUALITY

Even coverage provides excellent surface quality, with little to no back-rolling required.

HEA technology compared to handy accessories standard airless

With the HEA nozzle technology, a pre-atomiser nozzle is positioned ahead of the actual atomisation nozzle in order to atomise the material at the same delivery volume and working speed found in classic airless devices. The structure of the nozzle creates a particularly gentle, feathered spray jet. The result is better coverage with overlapping of the spray paths, less paint build-up at the start and end of the stroke and a better surface quality. This makes the tips particularly easy to use, saves material and ensures a perfect result. Hence, the coverage is improved with overlapping spray paths, the paint build-up is reduced at the start and end of the stroke and the surface quality is enhanced. The tips are user-friendly, material-saving and guarantee an impeccable end result.

What is Airless Spraying?

What is airless spraying?

What is Airless Spray Painting in simple terms? Airless spray painting is a method of applying paint without using compressed air. Instead, it relies on material pressure to spray the paint.

A pump which can be powered by electricity, air, or petrol pressurises the paint and forces it through the nozzle at a maximum pressure of up to 3625psi, creating the spray. 

How does spraying with airless work?

An airless paint sprayer uses the pump to build up pressure, up to 3625 psi, in the paint material. The pressurised paint is then forced through an airless spray gun. When the paint valve is opened, the paint passes through an opening in the spray tip, which determines the flow rate and width of the spray. The pressure difference between the paint and the atmosphere – atomises the paint, creating a fine mist for application.

Please note that our airless paint sprayers work with different pressures and therefore not all materials can be used with every machine.

Which materials can be used with airless sprayers?

Airless paint sprayers can handle a variety of materials, including water-based and solvent-based paints, varnishes, lacquers, oils, separating agents, synthetic resin-based paints, PVC paints, 2-K lacquers, primers, fillers, fireproofing paints, corrosion protection paints, emulsion and latex paints, adhesives, sealants, masonry paint, roof linings, floor coatings, silicon resin paint, and fillers with high viscosity.

How is airless spray painting different from using a paint roller or brush?

What is airless spray painting and who is it suitable for?

Airless spray painting is a technique that can be used by anyone who needs to perform regular and high-volume paint work. WAGNER airless paint sprayers, equipped with the new WAGNER HEA technology, allow both experienced decorators and first-time users to achieve excellent spray results easily.

What is HVLP?

What is HVLP?

Have you ever wondered what “HVLP” stands for?

Well, it stands for “high volume low pressure”, which refers to a paint spray system that uses a high volume of air at low pressure to achieve a fine and even spray pattern with minimal spray mist. Read on for full details. 

How does spraying with HVLP work?

  1. The turbine generates air flow that moves into the container and out through the gun nozzle. 
  2. As the air flows into the paint container, it compresses the air inside the container and pushes the paint through the suction tube towards the nozzle. 
  3.  The high air volume and low air pressure work together to atomise the paint into fine particles at the nozzle outlet, creating the spray jet.
  4.  

When using the nozzle, both the paint particles and the air stream are released together. This creates a “jacket” of air around the paint particles, which reduces the amount of spray mist and results in less material waste. As a user, you can enjoy better paint coverage and less material loss with this technology.

It is important to note that HVLP spraying produces larger micro paint particles compared to airless spraying due to the lower pressure used. This distinction may not be visible to the naked eye, but it is crucial to be aware of the differences between airless and HVLP to select the most appropriate sprayer for your project.

Which materials are suitable for HVLP sprayers?

Different materials can be sprayed with the HVLP paint sprayers.
We have prepared an overview for you here:

 

The following can be processed:

 

  • Varnishes and glazes
  • Interior Wall Paints
  • Exterior Paints
  • Primers
  • Wood stains
  • Oil based paint

It’s important to keep in mind that not all materials can be sprayed using WAGNER’s HVLP paint sprayers. WAGNER offers a range of equipment that is specifically designed for certain applications and materials, ensuring you achieve the best outcome. 

What should be considered when spraying with an HVLP paint spraying system?

To achieve a perfect spray painting finish, it’s essential to properly calibrate your equipment and dilute the material if needed. You should aim for smooth and even coverage, with no visible imperfections. Your success depends on various factors, including your sprayer, its settings, the type of material you’re using and your technique. To ensure the best outcome, we highly recommend that you carefully review the operating instructions for your sprayer and follow the manufacturer’s recommendations for paint dilution and ensure the surface preparation has been thorough. 

Materials can be used for different applications with the HVLP paint sprayers. Whether interiors or exteriors, you will always find a suitable sprayer for your application.

Double Diaphragm

The self-priming double diaphragm pump has not one but two diaphragms. These are connected to a piston rod and move together. Since it is a compressed air diaphragm pump, it is driven by compressed air (as the name suggests). Therefore, with each stroke of the piston, the pumped medium is simultaneously sucked in and delivered through the diaphragms, and this takes place with even less pulsation.

Diaphragm

A diaphragm pump uses a hydraulic piston to move a flexible diaphragm, which creates a vacuum that draws material into the pump. The material is then forced into a hose for transportation. This method is efficient for moving liquids, gases, and solids, and can handle large volumes of material thanks to the hydraulic piston.

WAGNER sprayers with piston pumps

Diaphragm pumps – How does it work, advantages and applications

This guide will provide a comprehensive explanation of how diaphragm pumps operate, their potential applications, and what sets WAGNER’s technology apart from traditional diaphragm pumps. The WAGNER brand of paint sprayers utilises a variety of pumps, including the diaphragm pump.

How does a diaphragm pump work?

The paint sprayer diaphragm pump efficiently utilises an electric motor and planetary gear to power the hydraulic pump. As a result, it propels the hydraulic oil under the diaphragm, which then enables the material to be sprayed with immense pressure from the spray gun. Moreover, the diaphragm doubles as a valve that automatically shuts the inlet valve and lets the material out through the outlet valve when pressed upwards, while creating a vacuum and drawing in more material when pulled down. This incredible function allows it to function as a vacuum pump. The pressure control valve works to limit the delivery pressure in the hydraulic oil circuit and the material pressure, which can be fine-tuned to control the spray jet.

The advantages of a diaphragm pump.

One of the notable advantages of diaphragm pumps is their continuous operation, ensuring consistent pressure and an even spray pattern without any pulsations. This is due to the diaphragm’s constant motion that eliminates the need for frequent stops, unlike other pumps. Moreover, these pumps have a purely mechanical design that doesn’t require any circuit board or control technology, significantly reducing maintenance needs. If replacement of parts is needed, it’s a quick and straightforward process. SuperFinish paint sprayers, equipped with a hopper, eliminate the need for a suction hose filled with paint. Diaphragm pumps can also be used with small diameter hoses, which require less material to fill, thus reducing material costs. Lastly, diaphragm pumps are specially designed for small amounts of material, making them ideal for specific applications.

Which materials can be processed with a diaphragm pump?

Many materials can be processed with the diaphragm pump! Including:

  • Primers
  • Separating agents
  • Undercoats
  • Varnish
  • Water based paints
  • Silicate paints
  • Corrosion protection
  • External paints and more

Higher-viscosity materials must be tested. Low-viscosity flame retardants, for example, can still be sprayed with a diaphragm pump. For more viscous fire protection, a different pump should be used. Filling compound or plaster is also not suitable for processing with the diaphragm pump.

What applications is a diaphragm pump suitable for?

The diaphragm pump is an incredibly versatile pump that can handle a range of small to medium-sized material applications with ease. It is particularly useful for woodworking projects, where it can spray primers, varnishes, and paints on wood and metal surfaces with great precision. 

This pump is also perfect for interior and exterior wall and ceiling painting, making it a go-to choice for many professionals in the industry. While it can handle materials with low to medium viscosity, it is not suitable for coarse or highly viscous substances like filler or plaster. For those materials, HeavyCoat or PlastCoat pumps with different capabilities are recommended. It is crucial to steer clear of using substances that are too highly viscous, as this can not only damage the device but also reduce its lifespan. Below are the Diaphragm pumps that we currently offer.
