Using a Backpack Sprayer

There are a lot of different uses for a backpack sprayer and knowing what you can and cannot do with different types of sprayers is very important to your safety, to the maintenance of your tank, wand and nozzle, and to the effectiveness of the job that you are undertaking.

You may be using one for pesticides (around the house, in a garden, yard or orchard), or perhaps you want to use a sprayer for staining the deck.  Understanding what you can and cannot do with a particular brand or style is very important.

Read through our articles below to learn about sprayers, choosing the best for your needs and how they make your life easier, less complicated and with a backpack sprayer – more comfortable.

What is a Good Backpack Sprayer

If backpack sprayers are new to you, then choosing one can be very overwhelming and determining what a good backpack sprayer is can be daunting.

The answer is … one that suits your needs.

If you have a large area to cover, then you should highly consider a battery operated backpack sprayer.  The main reason is that your arm won’t get sore and worn out from pumping constantly.  You may be strong, but after hours of pumping chemicals you will feel it in your arm, shoulder and back.

Battery Powered Lawn and Garden Sprayer

Battery Powered Lawn and Garden Sprayer

You have three options when it comes to batter powered lawn and garden sprayers.

  • Hand-held pumps
  • Wheeled Sprayers
  • Backpack Sprayers

Hand Held Garden Sprayers

These sprayers are typically used for small jobs around the yard.  You would not want to do any significant amount of spraying with these guys as they are not comfortable.  You can either carry the tank in your hand while spraying with the other, or you can sling it over your shoulder with the thin strap.  The strap is not padded and is uncomfortable to wear.

Wheeled Garden Sprayers

The wheeled sprayer is great if you will be walking on even terrain and not walking through shrubs, orchard or a garden.  It’s portable, easy to push or pull.

Backpack Sprayer with Boom Attachment

Having a backpack sprayer with a 2, 3 or 4 nozzle attachment is a great way to increase coverage and to reduce time to get the work done. Productivity at it’s finest.

If you are currently using a pump sprayer, your arm may become exhausted fairly quickly (even if you are fit), as you need to keep the pressure up in order to accommodate the extra nozzles.

Using this attachment will speed up the application of herbicides, pesticides or fertilizer that you may be using.

Backpack Sprayer with Boom

Our recommendation would be to use a boom attachment with a battery powered backpack sprayer for the 3 or 4 nozzle boom,  so that you don’t get tired before the job gets done.  The automatic sprayer will keep up the necessary psi to ensure an even flow of product.

The boom simply attaches to the wand of your sprayer and adds extra width to your spray pattern.

Typically a wand with 2 nozzles as a width of 24″, 3 nozzles have a width of 36″ and 4 nozzles have a width of 48″.

You can interchange the nozzles to meet your spraying needs.

Two companies which sell booms for backpack sprayers are Solo and Chapin which are designed to work with their own sprayers.


Understanding Spray Nozzles and Tip Color

Nozzles come in different sizes, angles, flow rates and types.  You need to understand these different options so that you can appropriately choose what nozzle to use for your situation.

There are twelve different designs.

color nozzle for backpack sprayersThe flow rate, is part of the tip number.  For example if you have a tip number of 06 it means that you get .6 gallons per minute rated at 40 psi.  In this example, the nozzle of 06 would be grey.

These different types provide different droplet sizes, spray angles, different pattern and different pressure flow.

spray pressure for backpack sprayersThis color coding system it to help you with a more accurate placement of product.  Generally speaking, a wide fan nozzle with a small opening with high pressure will result in smaller droplets – giving more coverage.

With smaller droplets, you do need to be cautious with wind factors as well.

Because you are carrying only 3 to 4 gallons for liquid in the tank, you want to make the most efficient use of you time and not be filling up your tank frequently.  The smaller the droplets, the wider the coverage, the more distance you can cover with each tank and less fatigue on you.

So if you want good coverage, you will need to break up the droplets as much as possible to cover more area.

Wind plays a big factor when spraying with smaller droplets as there is more chance of the product drifting with the wind, resulting is a less precise application and missing your intended target.

If you are spot spraying, then you will choose larger droplets with a more precise spray.  This will use a lot more liquid with the larger droplets and will provide less coverage (though more specific) and less drift.

air induction nozzle for a backpack sprayerAir Induction Nozzle

An air induction nozzle has holes on either side to allow air to flow into the nozzle chamber and mixes air with the spray solution.  It basically creates spray bubbles and provides less drift.

Air induction nozzles are very good at providing a uniform larger droplet that doesn’t drift.

This nozzle has two holes and each hole is half the size that it would typically be based on it’s color code.

We will be able to spray at two different angles with the volume of spray. It sprays at two different angles at the same time.  This is great to cover foliage.  As you walk it will spray ahead as well as behind as you continue walking.  You will be able to spray the plant at two different angles with a single pass of the sprayer.

It is going to produce very fine droplets which provides very good coverage.

This is an excellent choice for a backpack sprayer as you are getting great coverage, small amounts of product being used (less tank refilling) and less work for you.

Can I Use a Backpack Sprayer for Bleach

Best Backpack Sprayer for Bleach

These sprayers designed for bleach are great general clean up and for mold remediation.

If you are wanting to use a backpack sprayer for bleach, you want to ensure that you use a piston pump sprayer and not a diaphragm sprayer.

A piston pump sprayer has a sealed chamber that protects the unit from corrosion and damage.

In addition, you want to ensure that all O-rings are chemical resistant so that they will not break down and start leaking.

These O-ring seals are typically made of viron which is a synthetic and fluoropolymer elastomer.  They are highly impermeable to many strong organic solvents that would destroy or permeate common O-rings.

It is very important that you buy a bleach-specific backpack sprayer and not just any sprayer.

Garden Sprayer for Concrete Sealer

Using a Backpack Sprayer for Sealing Concrete

When using a sprayer to seal your concrete, you need to ensure that you are using a water-based, film forming protector.

First, you need to clean your concrete very well and give it at least a day to dry.  The next day you can seal, but you should make sure that your concrete is warm to the touch so that you know that you sealant will hold.

Apply the sealant with the pump sprayer in 50 to 60 foot sections.

using a garden sprayer to seal concrete - best backpack sprayer guideIts best if you use a circular motion for a more even layer of application and it is very important that you saturate the surface.

As you are going along, you should also “back roll” with a roller to evenly distribute the product and to get rid of any excess on the concrete.

Wait until the surface is dry to the touch, then apply a second coat.

How to Clean a Backpack Sprayer

There are common components with every sprayer that need to be cleaned an maintained.

The primary concern is the tank which needs to be cleaned both inside and out.  In addition, there is the hose which is attached to the spray wand and nozzle (it’s at the joint that you want to ensure gets cleaned properly as reside can build up behind the spray nozzle.

how to clean a backpack sprayerTips on How to Clean a Backpack Sprayer

To begin, add plain water to the tank and swish it around to wash down the tank walls inside.

You will want to pump to build a bit a pressure in the system, then with the wand facing down, spray out all of the water to ensure that you wash away any reside in the hose, wand and nozzle.

It’s really that simple.

I highly recommend that you wipe down the outside of the tank in case you had any spills or drips from the chemicals when you were emptying or loading the tank.

How Far Can a Backpack Sprayer Spray

You need to determine how you need your sprayer to spray before choosing a product to buy.  It makes a big difference if you are looking to hit the roof line of your home, garage, shed or barn vs spraying weeds in the yard.

You need to take into consideration the length of the wand as well as the type of spray the nozzle on the pump provides.  The wider the spray, then less distance it will spray.

Most backpack sprayer go the distance of 20-25 feet.
