A pump sprayer is a device that is used in spraying chemicals or solutions on gardens and even lawns. It is also called a pump-up sprayer and is very essential in spraying your lawn or garden when it has been invested with weeds. When using pump sprayers, it is important that you get a distribution of the chemicals that is uniform on the area being sprayed.
Overdosing or under dosing is highly discouraged as it may lead to unwanted results. There are various types of pump sprayers and each of these are used for various applications.
Things you need when using a pump sprayer
These are some of the essential things that you will need to make your pump spraying experience successful and with no hitches.
- A garden hose
- A marker that is permanent
- A tape measure
- A pair of gloves
- A pair of safety glasses
- Long sleeved clothes and pants
- A pair of gumboots or closed shoes
Steps to Follow When Using a Pump Sprayer
Step 1 :
First, you need to wear some protective clothing. Put on the long sleeved clothes and the pants, gumboots and the pair of safety glasses before getting started. Wearing some protective clothing helps prevent the chemicals being used to spray don’t come into contact with the skin.
Step 2 :
Next you should remove the top of the pump sprayer from the tank. This can be done by turning the top in a counter clockwise direction so as to get it opened. If your pump sprayer has a valve attached to the side of the tank, you should pull it out before opening the top so as to get rid of the excess air that is inside the tank.
Step 3 :
Once the top of the pump sprayer is opened, you need to fill the tank with water up to half of its volume or any other volume that is specified on the bottle containing the chemicals. It is important to note that some chemicals require to be more diluted as compared to others.
Step 4 :
The next step you have to take now is calculating the area that needs to be sprayed. You can do this by using the tape measure to measure the width and length of the whole area you will be spraying. Thereafter you multiply the length and width measured to find the area. Finding the area will be helpful in determining the proper amount of chemical that will be used to cover the whole area.
Step 5 :
Add the right amount of chemical to the water in the tank and put the top of the pump sprayer back and turn it clockwise until it is tightly put into position.
Step 6 :
Hold the handle on the top of the pump sprayer and pull it in an upwards direction. Then in a slow motion that is continuous and repeated, push it down and pull it up till it becomes hard to push it downwards. Completion of this process will mean that the tank is now well pressurized to begin spraying.
Step 7 :
Now with your gloved hands, hold the handle of the sprayer tip and start twisting it so as to either narrow or widen the pattern of spray that is achieved. It is important to note that a narrow pattern will prevent an over-spray onto areas that are unwanted while using a wide pattern will help spray large areas more fast.
The spray nozzle you will settle on will determine the amount of chemical that will be applied on the area, the uniformity of spraying, and the chemical coverage on the area that is being targeted as well as the amount of the potential drift of the chemical. There are three most common types of spray nozzles and they include;
Step 8 :
The flat fan- this particular spray nozzle is mainly applicable in broadcast and band spraying.
Step 9 :
The cone- this is mainly applicable in directed, spot and air assisted spraying.
Step 10 :
The streaming- this is mainly used in the application of liquid fertilizer in farms.
Step 11 :
When spraying, you should hold the sprayer nozzle in a position that is approximately 10 or 12 inches from the area being sprayed and then squeeze the trigger so as to dispense the chemical solution.
You should spray the plants until they are completely saturated and the chemical solution starts to drip off from them. Using the same manner, spray all the plants in the area till all the solution in the tank is used. When the pressure in the tank drops in the process of spraying, you should regain this pressure by pumping the handle close to six times.
Step 12 :
The solution in the tank may get finished before you are completely done with spraying the whole area. In this case, you need to open the top of the tank again and refill it. Before opening the tank, you should remember to open the pressure release valve if that particular pump sprayer has one. When opening the tank, you should it away from you so as to avoid spraying the chemicals on your eyes and face.
Step 13 :
Once you are completely done with the spraying, you should remove the top of the pump sprayer and rinse it well with the use of the garden hose. The water used to rinse the pump sprayer should be disposed in an area where it won’t affect the plants or pour it an open drain.
Step 14 :
Finally, after rinsing the pump sprayer, you should store it in a location that is covered and out of the reach of children. It is also important for you to clean the clothes, gloves and gumboots or shoes that you used during the spraying to avoid contamination and later take a bath yourself.
Once you follow the above steps carefully, the spraying will be done in no time. It is always advisable that you walk backwards while spraying so as to avoid walking on an area that you have already sprayed the chemicals on. You should also be careful when spraying so as to make sure that the over spray doesn’t land on unwanted areas.
