1
Stop spraying and move to a safe area
If the aerosol is behaving unexpectedly, stop using it and move the can away from people, heat and ignition sources before inspecting it.
Blocked Nozzle
A blocked nozzle is one of the most common aerosol problems and is often caused by dried coating left in or around the actuator after use.
Quick answer
Start with the safest checks: stop spraying, remove the actuator only if the product allows it, inspect the spray opening and replace the actuator if appropriate. Never pierce the valve.
What to do
2
Check the actuator
Look for dried paint around the spray opening, a loose actuator or visible damage. Do not force the actuator if it does not remove as intended.
3
Replace the actuator where appropriate
If the product uses a removable actuator and a suitable replacement is available, fit it securely and test the can according to the label.
4
Test the spray pattern
Carry out a short test spray on a suitable test surface. A clean, even fan or jet indicates that the actuator is functioning correctly.
5
Do not pierce the valve
Never use a pin, needle or drill to clear the valve. This can damage the can and create an unsafe release of pressurised product.
6
Clean the exterior after use
Wipe dried residue from the outside of the actuator after use and follow the product instructions for clearing the nozzle.
7
Store the aerosol correctly
Store the can as stated on the label, protected from excessive heat, frost and direct sunlight.
8
Contact us if the blockage persists
If a replacement actuator does not resolve the problem, stop using the can and contact AerosolsRus with the order and batch details.
Important
Follow the product label and current Technical and Safety Data Sheets. Do not modify, puncture or misuse aerosol containers.
Common mistakes to avoid
Pushing a sharp object into the nozzle
Review this point before continuing with your coating system.
Removing parts that are not designed to be removed
Review this point before continuing with your coating system.
Using solvents to soak the entire actuator without checking compatibility
Review this point before continuing with your coating system.
Continuing to spray while the nozzle is only partially clearing
Review this point before continuing with your coating system.
Storing cans with wet paint around the actuator
Review this point before continuing with your coating system.
Ignoring a damaged valve or can

Frequently asked questions
Can I remove an aerosol nozzle?
Some aerosols use removable actuators and some do not. Only remove it if the product design and instructions allow it.
Why does the nozzle block after spraying?
Residual coating can dry around the spray opening when the nozzle is not cleared or cleaned as instructed after use.
Can I wash a nozzle in solvent?
Only where the product instructions specifically permit it. Do not assume a solvent is compatible with every actuator material.
What if a new aerosol is blocked?
Do not force the valve. Contact AerosolsRus with your order details and photographs so the issue can be assessed.
How can I prevent blocked nozzles?
Follow the product instructions for clearing the actuator after spraying and store the can correctly.
