During winter months spraying jobs can decline, especially outside jobs; spraying fences, exterior renders etc…and generally the industry shuts down over Christmas. As you start to pack up your spray equipment how do you ensure it will be in full working when the holiday season has finished, and everything begins to defrost?
Preparing Your Graco Spray Equipment for Winter
As winter approaches, it’s essential to prepare your Graco spray equipment for the colder months. Proper preparation can prevent costly damage and ensure your equipment is ready for action when spring arrives. Here’s a comprehensive guide to help you winterise your spray machine effectively. Here are two important steps that could save you time and money!
1. Store Your Machine Correctly
The first step in winterising your Graco spray equipment is ensuring it’s stored in a suitable environment. Ideally, the machine should be kept in a space which isn’t susceptible to extreme heat. If indoor storage isn’t an option, consider using insulated covers to protect your equipment from harsh winter temperatures. It is important to note, however that even protecting your spray equipment from extreme temperatures, if left empty the ball valves are still likely to stick.
2. Protect the Pump from Freezing
One of the most critical components of your spray equipment is the pump. If left unprotected, the pump can freeze, leading to severe damage. Here’s how to safeguard it:
- Flush out the system: Make sure you don’t have any paint residue or water in the system. For more details on how to clean your machine, read our blog.
- Use Pump Armor: This specialist fluid is designed to prevent freezing. It coats the internal parts of the pump, providing a barrier against ice. Before storing your equipment, make sure to run Pump Armor through the system. This simple step can save you from costly repairs.

Understand the Risks of a Frozen Pump
Failing to protect your pump can lead to significant issues:
- Snap Piston Rod: When the pump freezes, the pressure buildup can cause the piston rod to snap, resulting in a complete loss of functionality.
- Need for Repacking: A damaged pump may require extensive repairs, including repacking. The costs for this can range from *£70 for a packing repair kit for a smaller machine. Metal components may start from around *£140. *The extent of the damage and labour costs for fitting and testing must also be taken into account.
- Damage to Drive Housing: If the pump freezes and damages the internal components, it can also lead to issues with the drive housing, compounding the repair costs and time needed to get your equipment back in working order.
Conclusion
Preparing your Graco spray equipment for winter is essential for maintaining its longevity and ensuring it’s ready for use when the warmer months return. By storing your machine properly, protecting the pump with Pump Armor, and understanding the risks associated with freezing, you can prevent costly damages and keep your equipment in optimal condition.
Take the time to winterise your spray equipment, and you’ll thank yourself when you’re ready for the first job of the New Year.
