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.
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:Sealer Concentrate: 100 Gallons
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:Sand: 300-500lbs
In cold weather increase the amount of FSA to 7-10 gallons.
