AK230 Pro Sealcoat Sprayer

The pumps are self-priming pumps so as long as your sealer is diluted properly and you have ample sealer in your tank your sprayer will self prime. Aways make sure that air isn’t sucking into the pump or you will lose prime and your pump will get quite hot potentially compromising the main seal which leads to a leaking pump.

If the sealer is too thick the pump will struggle with a prime as it’s like sucking a thick milkshake through a small straw.

Make sure your sealer is diluted at 20% to 30% at all times.

If you’re using the sealer within the week it can remain in the tank. Just periodically agitate the material in the tank to prevent it from settling and starting to cure.

If you want to remove the sealer from your main tank and store the sealer, we recommend taking off your spray tip and starting your unit up and then pumping the sealer into a drum or separate storage tank. Once this is done, flush your main tank out with water.

You can flush out your spray system by connecting the transfer kit or suction hose to a bucket or drum of water.

Simply turn your unit to Spray mode and spray the sealer back out into the drum or bucket that you got it from originally.

Our spray systems work only with Refined Coal Tar (Commercial Grade) Water-Based Sealer and we have specifically tested our systems with the coal tar sealer we sell on our site.

If you use:

• Asphalt Emulsion sealer, 
• a sealer with sand, 
• or oil based sealer,

the spray system will not work: the pump will need repair and you may even blow the engine.

If you use the wrong sealer your warranty is voided in the same way as if you were using diesel fuel in a gasoline engine for your truck. 

Yes, simply close the main valve on the bottom of the tote. Disconnect the suction hose from the bottom of the tote and then put that end of the hose in a 5 gallon pail and turn the valve above the pump to spray mode and then start the engine. The pump will suck the water up out of the 5 gallon pail into the pump and down the spray hose out the gun and then spray the water out of the gun back into the 5 gallon pail you just sucked up and you can recirculate it in the pail like this while having the engine on low idle.

We cannot warranty a system if sand has been used in it as it will wear and ruin the seals. We do however, suggest applying the sand by hand with a grass seeding machine after applying a thin wet coat of sealer and then applying a second coat of sealer over top of the sand layer as a final coat.

300 gallon metal tanks with sweep agitation blades mostly move the product contents near the outside walls of the storage tank. The heavy paddles usually rotate very slowly and are driven by cumbersome gears, chains, and pulleys. The product near the center of the tank may never even get mixed at all!

To observe this, try this revealing experiment:

First take a can of paint, secondly take a paint stir stick. Now stir the contents using the stir stick only along the inside edge of the paint can slowly. Try to emulate the speed of a paddle moving around the inside of a storage tank. What happens to the contents in the center of the paint can? Hardly moves or mixes at all doesn't it?

The re-circulation system that comes with the AK Tote, Drum, Portable, 130 and 230 Sprayers is absolutely amazing. Your sealer mixes up in 3 to 4 minutes and ready to apply.

These systems are field-tested with our own brand of Coal Tar asphalt sealer. The systems cannot spray sealer with sand, and they cannot spray Asphalt Emulsion sealer.

We can't guarantee the performance of the systems with other people's sealer because they may add additives that we don't know about that could affect the performance of the pump, hoses, circulation, etc. We use the industry's best-quality sealer and we can assure you that you will not have any issues with it; if you wish to use another brand of sealer please contact the manufacturer to guarantee performance with your spray system.

The 130 gallon system fits in trucks as small as Ford Rangers, Chevy S10's, or any full sized pickup truck.

The 230 gallon system fits in full sized pickup trucks like Ford F150's or larger.

Both systems fit in most trailers.

The 130 (130 Gallon Capacity) = 13,000 square feet of coverage.

The 230 (230 Gallon Capacity) = 23,000 square feet of coverage.

The filter connects to the output port of the pump, and then your spray hose connects to the filter kit.  

If a chunk of sealer, a stone, or a rock is blocking the output of the tip, it would create a blockage in the tip that would create a trickle or a pressurized multi-stream spray. Sealer sitting in the tank for a long period of the tank can dry on the side walls and form flakes. These flakes can fall into the rest of the sealer and get suctioned through to your spray tip, causing a blockage.

We heavily advise investing in a filter kit, as it filters out unwanted chunks. See more troubleshooting tips for if you lose pressure at the spray tip.

You get this when the sealer is too thick and the pump cannot create a prime to circulate the sealer. Dilute it properly to achieve 20 to 30% water dilution.

Use a dipstick to check the level of your sealer at the end of the day and the next time you use your system, just in case of water evaporation (if the levels are different, add enough water to regain the previous sealer level).

Another possible reason could involve the system's ball valve. On the output part of the pump, there's a ball valve that allows you to redirect the sealer to the top of the tank or to the spray gun. If that ball valve is constantly or permanently broken to the spray gun, you wouldn't get recirculation.
