Spray Systems

How do you prime the 130 or 230 Gallon Spray Systems?

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.

How do I clean out my spray system between uses?

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.

Can I spray sand with the 130 or 230 Gallon Spray Systems?

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

If you use:

  • 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. 

Does the Portable Spray System come with the suction and discharge hoses?

Yes it does.

How long is the hose?

This system includes a 50 foot 3/4" diameter hose, rated to 275psi.

Will the portable spray system work with a tote?

Yes, but not out of the box - you need to purchase the optional Tote Connection Kit.

Can I flush the unit without touching the sealer?

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.

Can this system spray sealer with sand in it?

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.

Does the system re-circulate as well as agitation systems?

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.

I'm getting an uneven spray pattern.

This usually happens due to the tip clogging or if the tip is worn out past a usable point. Make sure to clean your spray tips after every sealcoat job. Buy new spray tips and invest in a filter kit to prevent clogged spray tips.

What type of oil should I use?

Any standard 4-stroke motor oil (like 10W30) for lawn mowers, snow blowers, etc. can be used.

I'm getting foam on top of my sealer.

The cause of this is over-agitating the sealer. Only recirculate your sealer for 2-3 minutes max at the beginning of the day and maybe for a minute at the beginning of each job.

Do the 130 Gallon / 230 Gallon systems fit in a pickup truck?

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.

How many sq. feet of asphalt coverage do I get?

The 130 (130 Gallon Capacity) = 13,000 square feet (1,207.74 square meters) of coverage.

The 230 (230 Gallon Capacity) = 23,000 square feet (2,136.77 square meters) of coverage.

Can the AK55 be used with oil-based sealer?

No, none of Asphalt Kingdom's spray systems can be used with oil-based sealer.

Hello i bought a ak spray sytem and the filter kit.can you please tell me where i attach the filter kit thanks.

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

Is this self priming?

No. You will need to prime the system first before using it, then mix your sealer with a drill mixer prior to turning on your machine.

How can I tell if the aluminum pump has gone bad on my ak130 unit its really hot and doesn't seem to be pumping

Typically you will notice sealer leaking between the pump and engine casing.

What sort of sealer can I spray?

These systems are field-tested with our own brand of Coal Tar asphalt sealer and can be used with specific brands of Asphalt Emulsion sealer. The systems cannot spray sealer with sand.

Approved Sealers:

  • Coal Tar Emulsion
  • Asphalt Emulsion (AE): GemSeal, Sealmaster and Neyra sealers only without the addition of any latex additives

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 sealer is suddenly just trickling out of my spray tip. What caused this?

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.
