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. 

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.

One of the RynoWorx Crack Repair Machines' greatest advantages is how much bigger the nozzle is than the competition's.  That means it's less prone to plugging up when you're on the job.

Another innovation is that it is fully removable for cleaning. Start by heating it up with your accessory torch.  Using a pair of heat-proof gloves or vice grips, slide the valve right out and let the excess material flow out. This will leave a clear passage for the next crack repair job you are doing.

No. DSF does not contain any acrylic or brittle polyvinyl resins like some products. DSF rubberizes the seal coat as it cures where hardening additives cause the seal coat to become brittle which causes premature cracking or flaking.

We do not recommend using any other additives when using DSF. DSF is an all in one additive offering all the features and more of other additives combined. Your money would be wasted to use two products for the same result.

Here is the recommended ratio:

If your spray system is designed to work with sand (AK's Drum, Tote, Portable, 130 and 230 gallon systems do NOT work with sand) then you can also add:

In cold weather increase the amount of FSA to 7-10 gallons.
