Winterizing Sealcoat Equipment: A Step-By-Step Guide

Stowing your sealcoat spray system in the garage and calling it a day is not enough to winterize sealcoating equipment. You'll need to end the season right if you want sealcoating sprays, tanks, and other equipment ready to put into service when warmer temperatures roll around! And, don't worry. These steps are easy but can make a huge difference.

1. Check the Manual 

Always refer to your equipment's user manual since it usually includes a more detailed guide about storage and cleaning. If you don't have the documents, don't worry! You can always find a copy online, most likely from the manufacturer or the seller's website. If you cannot locate it, you can always send an email and ask for winterizing information. 

2. Empty the Tank 

Emptying the tank is one of the most crucial steps in winterizing sealcoat equipment because the integrity of any leftover sealcoat is compromised when it freezes. As matter of fact, frozen sealcoat is no longer usable. So, unless you want to repurchase sealcoat and spend more money, make sure that you empty the tank. 

Pro Tip: Ensure that the leftover sealcoat is stored in a clean and tightly sealed drum. And, never store the drum outdoors where it's exposed to cold temperatures. As much as possible, you should keep the drum in an area wherein the temperature is warmer. Use supplementary garage heaters if necessary. 

3. Clean Pumps and Hoses 

After draining the tank and putting the leftover sealcoat in a tightly sealed drum, the next step is to disassemble the components (pumps and hoses) and flush them with water. As mentioned, sealcoat can freeze during winter. And, the last thing you'd want is to have sealcoat residues clogging the pumps and hoses.

4. Drain and Open the Valves 

When the pumps and hoses are cleared of any sealcoat residues, don't close them. Keep them open so that the remaining water can evaporate on its own. 

5. Thoroughly Clean the Tank 

Another crucial winterizing sealcoat equipment step is cleaning the tank. Over time, dried sealers stuck on the tank's walls will chip off. When spring arrives, loose chunks will cause clogging and wreak havoc to your entire spray system

Pro Tip: Sealer is more challenging to handle when it's still wet. If it's dry, you can easily scrape it off from the tank's walls. So, give ample time for the tank to air out. Subsequently, you can speed up the "drying" process by placing a room fan on the tank. 

6. Flush the Motor Oil From the Pump 

Motor oil from the pump can also freeze during the winter months. So, make sure to remove the oil and add antifreeze before storing. Don't skip this step. If neglected, there is a huge possibility that the leather seals will dry out, and the pump housing will rust.

7. Remove and Store Other Components 

The last step in winterizing sealcoating equipment is to detach other components like spray wand and hose from the machine. Similar to step 2, keep them in a warm place; cold and freezing temperatures can make them brittle.
