Preparing your sealcoating equipment properly is the key to smooth, efficient, and professional results. Whether you’re gearing up for your first job or just need a refresher, getting the basics right will save you time, prevent breakdowns, and ensure your asphalt sealer sprays beautifully.

In this guide, we’ll walk you through the full process: checking your equipment, mixing sealer in drums, loading it into your spray system, priming the pump, and cleaning up afterward. Let’s dive in.

Step 1: Pre-Inspection Checks

Before you even think about loading sealer, take a few minutes to check your equipment:

These simple checks help avoid major headaches later on and are an essential habit before every project.

Step 2: Understanding Your Loading Options

There are two main ways to load sealer into your spray system:

1. Fill at a Plant: Open the top lid of the tank and have the plant hose fill the tank directly. This method is fast and efficient if you are near a supply facility.
2. Fill from Drums: Use the 2-inch loading port to pull sealer from 55-gallon drums. This method offers flexibility if you're working remotely or prefer to stock your sealer ahead of time.

For many contractors and DIYers, filling from drums is a more accessible option, especially when just starting out.

Step 3: How to Properly Mix Sealer in 55-Gallon Drums

Unmixed sealer is mostly water on top and thick clay-like material at the bottom. If not mixed properly, the sealer won't perform as intended, leading to uneven surfaces and premature wear.

Tools You Need

Mixing Process

1. Remove the Drum Lid: Take off the drum hardware and carefully remove the lid.
2. Do a Dipstick Test: Stick a clean broom handle straight down to the bottom of the drum and pull it up. If you see a visible separation between watery liquid and heavy sludge, the sealer needs thorough mixing.
3. Insert the Drill Mixer: Start mixing at the bottom of the drum. Use an up-and-down, side-to-side motion to break up settled material.
4. Mix Thoroughly: Continue mixing for about 4-5 minutes until the sealer reaches a uniform consistency similar to thin pudding or thick gravy.

Final Check

After mixing, repeat the dipstick test. You should see a solid, uniform black line from top to bottom with no visible separation.

Proper mixing ensures the sealer will cure correctly on asphalt surfaces, providing the durability and protection your clients expect.

Step 4: Preparing the Transfer System

Here’s how to get your spray system ready to load sealer:

• • Remove the plug from your transfer port.
  • Attach the male end of the transfer hose to the loading port.
  • Lock the cam clamps securely to prevent leaks.

Priming the System

Before transferring sealer, you must prime your pump and hoses:

Priming ensures a smooth transfer. If air is trapped inside, the pump could struggle, potentially damaging the equipment.

Step 5: Loading Sealer into Your Tank

Now you're ready to load sealer into your spray tank:

Make sure your bottom ball valve is closed and top ball valve is open to allow proper loading without causing airlocks.

Proper loading technique saves time, prevents pump wear, and ensures you have the right amount of sealer ready for spraying.

Step 6: Cleaning Up After Loading

Never overlook the importance of cleaning up immediately after loading sealer. Residual sealer left on the hose and fittings can harden, leading to frustrating problems the next time you need to work.

• Clean the Transfer Kit:
  • Use a garden hose to rinse off the barrel kit, hose ends, and any other exposed parts.
  • Scrape off any residual sealer before it dries.
• Seal the Drums:
  • Cover any partially used drums securely to prevent contamination.
  • Label the drums if necessary, especially if you’re planning to mix or use them on another project.
• Secure the Hose:
  • Connect both ends of the transfer hose to each other to prevent drying inside.
  • Store it in a clean, dry location.

Taking a few minutes to clean now can save hours of frustration later and extends the life of your equipment significantly.

Final Tips for Long-Term Success

Developing these habits early will keep your spray system in top shape and your business running efficiently.

With proper prep, you’ll not only produce professional results but also extend the life of your sealcoating equipment. Whether you're tackling your first driveway or managing large commercial lots, following these steps ensures a smooth, stress-free job every time.
