Troubleshooting Questions and Answers

Why is my sealcoating tip clogging? How can I fix a poor spray pattern?

A blockage can easily occur if a solid piece of sealer or a stone gets stuck in the sealcoating tip. A trickle from the spray gun or an odd spray pattern is another indication of a blockage. To prevent blockages from forming, you can invest in a filter kit to filter chunks of sealer out during the suction process.

Another possibility of poor spraying are spray tips that have worn out — new spray tips when your spray tips are worn out or clogged should help fix this.

There is a leak from the pump. Why is that and how to fix it?

A leak can occur if the pump overheats from running the pump without liquid. The overheating pump heats up the master seal, making it dry out and crack. You can add water to the pump for priming, so that you will never run the pump dry and won't damage the seal. If the damage is done, we have a seal replacement kit.

What oil can be used with the sealcoating systems?

You can use 10W30 or any typical 4-stroke motor oil.

How do I prime the pump? When should I prime the pump?

You can prime the pump by adding 1 gallon of water to the pump. Running the pump with the water will create the suction needed to start sealer recirculation and spraying.

You need to prime the pump the very first time you use your system. If you haven't used the system for over 24 hours, you will need to prime the pump with water again.

Why is my sealcoating system not agitating?

If your sealcoating system isn't agitating, your sealer may be too thick. Since sealer is sold as a concentrate, you need to dilute it for use with sealcoating systems. You should add 20 to 30% water dilution, so if you have 100 gallons of sealer, you would add 20 to 30 gallons of water.

To ensure that water evaporation isn't occurring, you should check the levels of your sealer at the end of the day and the next time you use your system. If the sealer levels didn't match, you would add water to get the previous level.

If your sealer is properly diluted, you should check the ball valve on your sprayer system's output. This is the ball valve that lets you direct the sealer back into the tank or to the spraying gun. If the ball valve is stuck to the spray gun output, you would never get pump agitation.

Why am I getting foam on the top of my sealer?

If you agitate the sealer for too long, your sealer will start to accumulate foam on the top. You'll only have to recirculate at the start of the workday for 2 to 3 minutes, and then before each job for a minute.

Frequently Asked Questions about Our Spray Systems

Does my spray system come ready to go or do I need to assemble it?

Your Asphalt Kingdom spray system comes fully assembled and ready to go. Just add gas and asphalt sealer and you're all set.
