Tank Sealer

Yes, drain the used KBS Klean solution into a bucket and keep the KBS Klean solution until you can inspect the inside of the tank to verify it has been cleaned well.

You can filter the KBS Klean solution as it gets drained into the bucket to clean out the rust and junk from the dirty KBS Klean solution.

You can always re-use the KBS Klean solution if the inside of the tank needs additional cleaning. Some customers have cleaned their tank up to ten times which all depends on how dirty and nasty the inside of your tank is when you start.

Pro Tip: Placing some nuts & bolts or loose chains inside the tank, along with frequent shaking and rotation with the KBS Klean solution, will help knock away loose rust and contaminants.

It is always best to do all three steps (KBS Klean, RustBlast, Tank Sealer) when the ambient and surface temperature are above 55 degrees.

Pro Tip: KBS Klean and RustBlast are more effective when the ambient air and surface are warmer up to 80F.

Because there is usually moisture in the air, it is quite common for a metal surface to flash rust after being rinsed with water. RustBlast is formulated to leave behind a dusting of zinc phosphate. The zinc phosphate aids in the adhesion of Tank Sealer. Zinc phosphate is white in color.

So, when the tank is rinsed after the RustBlast step, there is the dusting of white zinc phosphate that is left on the surface and that mixes with the brown surface rust. This often makes the appearance of the surface rust appear much worse because most of what is seen is the dusting of zinc phosphate.

If what you have is a dusting on the surface and the tank is bone dry, you care good to proceed to the Tank Sealer step.

TIP: You can always minimize the amount of surface rust by drying the tank immediately and quickly after the tank has been rinsed with water after the RustBlast step, but this is not necessary.

Yes, the KBS Tank Sealer System is designed to prep and seal bio-diesel tank. KBS Tank Sealer is completely impervious to bio-diesel making it the ideal solution for sealing up a bio-diesel tank.

Yes, the KBS Tank Sealer System is used all the time to prep and seal up oil tanks. PRO TOP: The key with oil tanks is to be sure you prep the surface well because any oil residue that is not cleaned from the inside of the tank could cause long-term performance issues.

We designed Tank Sealer to be a long-term rust prevention and sealer solution and we also developed the prep process to complement and enhance the performance of Tank Sealer. It is certainly possible to use the Tank Sealer without using KBS Klean and RustBlast, but you are risking the chance that the Tank Sealer will not adhere well and prematurely fail. KBS Klean cleans the surface well and RustBlast etches the surface to leave an anchor pattern, so you get incredible adhesion of the Tank Sealer.

As with any coatings job, the prep is 90% of the job and the same is true with the KBS Tank Sealer System. If you want the longest-term results, it is always best to do all three steps of the KBS Tank Sealer System.

KBS Klean is a powerful cleaning concentrate and can be diluted 10-parts hot water to 1-part KBS Klean for most cleaning applications, but it is BEST to use KBS Klean full strength when cleaning the inside of a tank as tanks typically require the maximum cleaning power available. Full strength for KBS Klean is 1-part hot Water and 1-part KBS Klean and that is what we recommend using when cleaning the inside of a tank.

The KBS 3-Step Tank Sealer System is absolutely ideal for new tanks. If you leave a new tank uncoated, it will eventually rust leaving you with clogged fuel filters.

A very common misconception with sealing new tanks is that you do not need the KBS Klean and RustBlast. New tanks made of new steel are very slick and not an ideal surface for Tank Sealer to stick, so we always recommend KBS Klean and RustBlast to properly clean and etch the surface of the new tank so the Tank Sealer can bite into the surface and adhere permanently.

Yes, you can do multiple tanks with a single appropriately sized Tank Sealer Kit.

To do this, be sure to prep both tanks well and then pour part of the can of Tank Sealer into one tank and then the other part of the can of Tank Sealer into the other tank immediately. Never drain the Tank Sealer from one tank to another.

You can also pour part of the Tank Sealer into a prepped tank and then put plastic between the lid and the can of Tank Sealer and store the Tank Sealer for later use (within six months).

KBS Klean and RustBlast can be used on multiple tanks, and if needed, can be poured from one tank to the next. You can typically prep a few tanks with KBS Klean and RustBlast without losing any effectiveness.

Yes, prepping and sealing up air compressor tanks is an extremely popular application for the KBS Tank Sealer System. Most air compressor tanks develop rust over time from the condensation that develops on the inside of the air compressor tank and this rust can eventually cause leaks in the tank. For this reason, many people prep and seal the inside of their compressor tanks, so they do not have to be concerned about rust forming in the tank down the road.

For air compressor tanks that already have a pinhole leak (tip of a pin), the KBS Tank Sealer System will seal up that pinhole leak and protect it from getting any larger.

The BackBone Fiberglass Mesh is used for areas of your tank that need to be reinforced. If you have pinholes and weak areas, you can use the BackBone Fiberglass Mesh with some Tank Sealer on the outside of your tank to reinforce that area.

Use KBS BackBone Reinforcing Mesh for exterior repair of pinholes or weld seams. Prior to patching, prep the outside and inside of the tank by using KBS Klean and RustBlast and allow all surfaces to dry completely. Begin by sealing the inside of the tank as outlined above. After sealing, immediately use any remaining Tank Sealer to paint a thin layer on the exterior pinhole area(s). Using a suitably sized piece of BackBone Mesh, embed it directly into the wet Tank Sealer and apply another thin coat of Tank Sealer painting outward from the center. Let cure.

There are thousands of different types of plastics and polyethelynes in use today and they continue to change every year. Because there are so many out there, it is impossible to test all the plastics and polyethelynes for adhesion and compatibility. Therefore, we cannot completely recommend our tank sealer kits for plastic or polyethelyne tanks.

What we have found over the years is that many plastic and polyethelyne tank owners are so desperate that they have been willing to try it regardless of the results. The surprising thing is that most, but not all, have great results. The success is due to the fact the more porous the plastic or polyethelyne, the more it leaks. But this also means the more porous the plastic, the better the gas tank sealer can stick because our Tank Sealer loves porous surfaces.

In conclusion, we cannot recommend our tank sealer kits for plastic or polyethelyne fuel tanks. But, if you are desperate, you can certainly give it a shot.

Tank Sealer is formulated and designed to stick to a bare surface that has been prepped with KBS Klean(cleaner) and RustBlast(acid etch). With that in mind, it is always a good idea to strip out the previous sealer with KBS Strip.

Directions for Stripping Out Old Tank Liner

Use KBS Strip for the most effective removal of an old, failed coating. Pour some KBS Strip into tank and carefully rotate tank to allow contact with all sides. It may take multiple applications of KBS Strip to finish the job completely. Old Sealer may come loose in big chunks or small pieces so use a long tweezers-type tool to help remove it from the tank. After stripping is complete, rinse tank generously with water and proceed with the KBS 3-Step Tank Sealer System for Fuel Tank Preparation & Sealing. (NOTE: When stripping a Fiberglass Tank, surface contact with the stripping agent should be kept to a minimum to avoid the attack & weakening of the fiberglass resin.)

After you have the previous liner out of the tank, you can proceed with the KBS 3-Step Tank Sealing System.
