The Bottom Line
Learn Before You Buy
We selected a power-packed 6.5hp Briggs engine and a 2" CAST IRON pump with Viton Seals designed especially for sealcoat.
The AK230 includes manual paddle agitation sweep. This one feature alone usually costs an extra $550 but we decided to include it for free for a limited time. Manual agitation always ensures that your sealer is mixed properly in your tank.
The AK230 can also be accessorized to enhance the performance and management of your spray machine. You can add a filter kit so that you filter out any unwanted chunks and prevent them from blocking the tip of your gun. You can also add a hose reel that will allow you to keep your spray hose neat so that you spend less time untangling and more time getting the job done. You can also add a transfer kit that will allow you to transfer sealer from drums, totes or other sealer sources over to your main 230 gallon tank.

Questions & Answers
The sprayer tip isn't spraying correctly.
Poor spraying can occur if there is something blocking the sprayer tip – this could be from a solid piece of sealer or a rock getting stuck in the sprayer tip. Sealer at the top of your tank can dry into flakes along the tank's walls, and can fall to the bottom of your tank, allowing these flakes to get pushed through into your spray gun. The flake can cause a blockage, which can result in the spray gun trickling or having multiple spray streams coming out of the tip. To avoid having to worry about tip blockages, you can get a filter kit that will take out any chunks or flakes of sealer.
The spray pump leaks.
If the spray pump is leaking, it could be a sign that your pump has been overheated from running the pump while it's dry. There is a master seal that can crack if the pump is run dry, so it is very important to only run the pump with liquid. If you're using the pump for the very first time or after not having used your system for over 24 hours, you can add a gallon of water to the pump for priming.
The oil to use.
You can use any typical 4-stroke motor oil, such as 10W30.
Priming the pump.
Why: Priming the pump is important so that you do not run the pump dry. This can lead to the pump overheating and the seals wearing out or cracking. When: You only need to prime the pump if it's the very first time you're using it, or if you haven't used your machine for a full day. How: Add 1 water gallon to the pump via the orifice and run the pump. The pump will immediately push the water through, and the force will pull in the sealer and create the appropriate suction.
Odd spray pattern.
An uneven or an odd spray pattern could be caused by a blockage / clogged tip or if the tip is very worn out. We would suggest getting new spray tips and keeping a variety of spray tips for back-ups, and to invest in a filter kit to remove unwanted sealer chunks (which will prevent clogging at your spray tip).
Agitation is not working or the system isn't spraying.
If the system isn't pulling sealer from the tank, then the sealer could be too thick. Sealer is sold as a concentrate; if using in a spray system, it needs to be diluted (20 to 30% water dilution is standard). Another thing that can cause your sealer to become too thick (if you've been properly diluting your sealer already) is water evaporation. Check the level of your sealer when you store it at the end of the day. Re-check it the next time you use your system; if the two measurements match then no water evaporation has occurred. However, if the two measurements are different, you need to add enough water to your tank to get your sealer level back to the first measurement.
If the sealer is properly diluted and there is still no agitation, check the ball valve on the output part of the pump. If it is set to direct sealer to the spray gun (or if it's broken permanently to the spray gun output), no recirculation will take place.
The sealer is foaming at the top.
Sealer will start to foam if it's being overagitated (imagine putting a milkshake into a blender and overblending it – it turns to foam!). You only need to agitate your sealer for a few minutes (2-3) at the start of each day, and perhaps for a minute at the start of your jobs.
