Handheld Sprayer: Tips from Professionals

A handheld sprayer is a handy tool for gardeners and farmers. From controlling pests on a small scale to large-scale weed management, they allow you to effectively and efficiently apply liquids to any surface. They come in various models, including manual and powered ones. One can say there’s a handheld sprayer to suit every need.

Handheld sprayer:

A handheld sprayer is a portable device to spray liquids onto various surfaces, such as pesticides, herbicides, fertilizers, and cleaning solutions. They consist of a container that holds the liquid, a pump or motor that pressurizes it, and a nozzle to control the flow and direction of the spray. Handheld sprayers come in various sizes and types and can be manual or powered.

In this article, I will explain different aspects of handheld sprayers and some frequently asked questions that I often get.

Types of handheld sprayers

Handheld or backpack sprayers can be divided into three main types, manually operated, battery-powered, or gas-powered:

  • Manual sprayers: These handheld sprayers are operated manually with a hand pump. There are two main pump types, i.e., piston and diaphragm. A piston creates a finer mist, while a diaphragm produces a coarser mist.
  • Battery-Powered sprayers: Battery-powered sprayers use a motor powered with a rechargeable battery. They make the job easier as the user requires no force or action other than directing the spray. They come in various sizes ranging from one gallon to five gallons and are generally worn as a backpack.
  • Gas-Powered sprayers: Gas-powered sprayers use a motor powered by a gas engine. They are generally bigger and suited for heavy-duty jobs. They make much more noise than battery-powered ones, and the gas engine needs much more maintenance. Gas-powered sprayers also come in several sizes and are available as a backpack.

How to use a handheld pump sprayer

If weeds have taken over your lawn or garden, using chemicals is one of the options. In that case, a pump sprayer is one of the ways to deliver the chemicals where they need to go. They are excellent tools to treat large areas without cramping your trigger finger from using a spray bottle.

Pump-style sprayers are manually operated and require some work to create the vacuum before you can start. As with every sprayer, you must ensure you use the correct mix of chemicals.

Follow these steps to use a handheld pump sprayer:

  • Step 1. Personal Safety: Before starting, wear a long-sleeved shirt and pants, work gloves, safety glasses, and closed-toed shoes. Wearing protective clothing protects your skin from contact with chemicals.
  • Step 2. Setting up Tank. Remove the sprayer from the tank, and let any excess air from the tank. Pull out any valves on the tank’s side before removing the lid.
  • Step 3. Clean the tank: Ensure the tank is clean. If needed, clean it. You do not want to have any residue from the previous usage.
  • Step 4. Fill the tank: Check how the herbicide needs to be used. You must fill the tank halfway with water and add the herbicide for many solutions. Always check the user manual on what to do.
  • Step 5. Close the sprayer: Insert the sprayer’s lid back and tighten it clockwise until it is closed.
  • Step 6. Pressurizing: Take hold of the lid’s handle and pull it up. Push it down and pull it up in a slow, continuous motion until pushing it down becomes difficult. This indicates that the canister has been adequately pressurized.
  • Step 7. Setting the nozzle: Using your gloved hand, grasp the sprayer tip’s nozzle and twist it to either narrow or widen the spray pattern. Use a narrow pattern to avoid overspray on undesirable plants and a wide pattern to treat large areas quickly.
  • Step 8. Start spraying: Squeeze the trigger to dispense the herbicide and position the sprayer nozzle 10 to 12 inches away from the weeds. Check the manual for the exact usage.
  • Step 9. Repressureize: Pump the handle five to six times to repressurize the tank during use if you see that the spray loses power.
  • Step 10. Cleaning up: Remove the sprayer’s lid and thoroughly rinse it with a garden hose. Please dispose of the water somewhere it won’t kill or flush the plants down the drain.

How do garden hose sprayers work

Garden hose sprayers are attached to the end of a regular garden hose and use the water pressure from the hose to spray mixed liquid solutions. They consist of a container that holds the liquid chemicals and a nozzle that attaches to the end of the hose.

Here are the basic steps to using a garden hose sprayer:

  • Step 1. Prepare the solution: Mix the right amount of chemicals with water using the instruction label or manual. This is essential, as you do not want to work with the wrong solution.
  • Step 2. Fill the container: Open the container and solution in it. Leave some room for the air at the top.
  • Step 3. Attach the nozzle: Connect the nozzle with the garden hose. Keep the connection tight and check that there is no leakage.
  • Step 4. Adjust the nozzle: Most garden hose sprayers have special nozzles that can be adjusted. They allow flow and direction control. Experiment with different settings to find the best one for your task.
  • Step 5. Turn on the water: Turn on the sprayer and adjust the flow to the desired level.
  • Step 6. Start spraying: Hold the nozzle steady and spray the solution onto the intended surface. Keep a safe distance between the nozzle and the surface to avoid applying too much solution.
  • Step 7. Clean the sprayer: Clean it thoroughly after use, preparing it for subsequent use and helping prevent clogs.

How much pressure should a pump sprayer have

A pump sprayer’s pressure is expressed in pounds per square inch (PSI). The optimal pressure for a pump sprayer will vary depending on the precise activity and the liquid solution being applied.

For most cases, a pump sprayer should have a pressure of about 40 to 60 PSI. This range is ideal for most applications, including pesticides, herbicides, and routine cleaning duties.

Although some handheld pump sprayers have a maximum pressure of 90 PSI, these high-pressure settings are needed for heavier-duty applications like dispensing viscous liquids or reaching higher surfaces.

Different pressure levels can be necessary for specific solutions. For instance, some delicate plants or flowers could need less pressure to prevent breaking or harm. On the other hand, some tough cleaning jobs might need more pressure to get rid of dirt and grime properly.

Finally, it is essential to check the product label and instructions for the recommended pressure range of the specific liquid being used.

How far will a pump sprayer spray

Several factors dictate the distance that a pump sprayer can spray. These factors are:

Pump sprayer Nozzle: An average pump sprayer with a pressure range of 40-60 PSI can usually cover 20-30 feet horizontally. However, if a nozzle with a wide spray pattern is used, the distance will be less, but the covered area will be larger. With a small spray pattern, the distance will be larger. This is similar to a garden hose.

The thickness of the spraying liquid: How distance also depends on the viscosity of the solution. Thicker liquids will not spray as far as thinner liquids. That is why ensuring the right amount of dilution, and the correct pressure for each job is important.

Environment: It’s important to remember that wind and other environmental conditions can also affect the distance a pump sprayer can reach. With wind, the liquid can get much further than with no wind.

How do you spray tall trees?

You can take care of small and even medium trees using a ladder. For a tall tree, I recommend making use of specialized spraying equipment. With such sprayers, you can spray a tall tree and do not need to leave the ground.

These machines have more extended handles and generally use a higher pressure that can reach high into the air. They typically have a larger liquid container with a spray rate of 30-60 Gallons per minute.

Step 1. Fill the liquid container:

Fill the liquid container from the high-pressure air blast sprayer tank or a hydraulic sprayer with the herbicide solution. Check the manual on how to prepare the solution.

Step 2. Set up the sprayer:

Position the sprayer away from the tree base so that you spray at an angle toward the tree limbs while avoiding getting any spray over yourself. Spraying at an angle also has the advantage that the spray travelers easier through the tree branches and is less obstructed by the lower ones.

Step 3. Start spraying:

Start the sprayer and check how the spray looks and leaves the nozzle. For the nozzle to send a directed spray to the height of the tree limbs before dispersing into a fine mist, twist the nozzle until the spray reaches the intended area.

The sprayer must lift the chemical fluid to the correct height before transforming the spray into a fine mist that can cover the branches and leaves of the tree to avoid tearing them.

Step 4. Walking around:

As you spray, walking around the entire tree will ensure complete coverage of all branches and leaves. Depending on the problem with the tree and the chemical used, you may need to coat the trunk, limbs, leaves, or a combination of those parts.

It is important to read the instruction manual of the chemical to determine exactly what part of the tree should be sprayed, how much liquid is needed, and how frequently it should be used.

What is the difference between a sprayer and a duster

A sprayer and a duster are used for applying liquid/powder solutions on affected surfaces, but they work in different ways and are intended for different purposes.

A sprayer uses a pump mechanism to pressurize a liquid and then sprays it through a nozzle. Sprayers come in a variety of types, including hand-held or backpacks. They are used for various tasks, such as applying pesticides, herbicides, fertilizers, and cleaning solutions.

A duster uses air pressure or mechanical vibration to blow a powdery material through a nozzle. Dusters can be handheld or backpack-style and are mainly used for applying pesticides, herbicides, and fertilizers in dry form. Dusters are used for areas that are hard to reach with a sprayer.

A sprayer applies liquids and some powders, while a duster is used primarily for applying dry powders. The choice between a sprayer and a duster will depend on the task and the solution used.

Can you spray paint with a garden sprayer?

You can use a garden sprayer to paint, but there are some steps you should follow before you start. These depend on the type of paint used: water or oil.

Spray Water-based paint with a garden sprayer

  • Step 1: Prepare the solution. Most latex paints are water-based and thick and should be diluted before using them in a garden sprayer. I recommend using one part paint to three parts water.
  • Step 2: Fill the sprayer. Swirl and shake the mixture gently, and fill the garden sprayer with the mixture.
  • Step 3: Start spraying. Spray the paint as a fine mist as much as possible. This lowers the chance of clogging the sprayer nozzle, and adjust the nozzle as needed. To achieve the consistency of one brush coat of undiluted paint, apply several (up to four) spray coats. This diluted paint works best on horizontal surfaces because vertical surfaces are prone to dripping and running. Only spray a thin layer for vertical surfaces, let it dry, and repeat more often.

Spray Oil-based paint with a garden sprayer

  • Step 1. Prepare the solution: For the use of oil-based paint, I recommend to diluted it 50/50. Swirl the mixture around and give it a good shake.
  • Step 2. Start spraying: Spray as fine a mist as possible to ensure the nozzle is not clogging. Change the spray nozzle setting, or use another nozzle. Spray two coats of oil-based paint or stain to make one regular coat.
