Resimac 200 Series – For Pump Repair and refurbishments with Chris Mathson from Resimac

Lately Unconventional Solutions has been getting a lot of requests for information about pump repairs. Some requests that have been coming in. One is a typical erosive damage on the inside of the pump that needs to be repaired. Sometimes the pumps are 50-60 years old, and it is just really hard to replace them. They are also wanting, when asked, to increase the fluid flow.
 
FUN FACT: Around the world is spent on moving water via pumps, so that cost can get pretty high, and that coating actually tends to pay for itself pretty quickly in that process. 
 
It seems that energy costs are going up, and to take the factor to help process plants help their energy costs go down over time. The older the part / pump gets the more energy and maintenance it will use over the lifespan of the product.
 
How do you keep a pump in service? How do you keep good flow? When pumps age, it is not only the replacement of the pump; it is also the replacement parts that add to the cost.
 

The ability to bring back the OEM efficiency and increase the flow, energy cost, wear resistance, etc.—that is what we want to help with. The Resimac 200 Series are great products to help with these problems. To coat on, you can’t really coat over a divot. It’s going to entrap air. It’s going to have other issues, you know, just in the application process. And of course that’s going to be a weak spot if you don’t address it first. So those are the things. This is a cold weld, if you will, like a weld replacement.

It’s a two-part epoxy that has ceramic filler in it, and those are the things that it’s designed to fill in the pitting to rebuild, you know, restore that worn metal surface back to a semi- or completely uniform state.

Finish . It’s, you know, surface prior to probably overcoating it with what you’re going to show next, which is that ceramic fluid coat, you know, the brushable coating. You have 2 layers. A lot of shops will simply fill in the pitting because that’s what they have the budget and the time to do, but over time this area will wear.
 
Repack it. If you’re going to do the maintenance, why not go those extra couple of steps to abrasively blast the surface, clean it up, fill in the pits, and then apply a two-part epoxy ceramic coating over top of it? What they saw then was that efficiency gain.
 

The best return on your investment is in protecting and restoring that asset back to the performance that you are looking for without the need of replacing it.

If you would like to see the full study from 2026, we can send it to you. There is a right solution/application for your problem.

We typically suggest doing the 2-layer system. That tells you it’s time to reapply that coat. That way you don’t ever eat into that metal again; you’re only eating through.



QUESTION:
What types of pump failures or which areas do you see most often where these repair products make the biggest impact?
 
ANSWER: The older pumps that have been functioning for a long time are the ones that have erosion on the interior. The new ones are not the same size and form. All of the areas have a continual flow, and if it picks up some materials, it becomes rough. We may fill in holes and cracks and protect it with a top coat. And put them back to work. There could be a number of various reasons why it might wear down, erode, or wear away in that location, right? It could be a solid, a chemical, something that is really hot, or something that is not from this world. There are paste-grade materials and system coatings that will work for what you require.



QUESTION:
When you’re looking at the 200 series in the field, how do you typically position 201 versus 202 versus 203 depending on the failure mode, especially when you’re dealing with erosion versus corrosion versus mechanical damage?
 
ANSWER: The solution is simple: the 201 and 202 are not the same. 201 is a substance that is used to grade speed. So, when you think about it, fixing your car is like putting in body filler. If you have those gouges, pitting, or cracks, it’s easy. That’s the stuff that fills in the gaps (damage from erosion or corrosion). You’re rebuilding with the 201 pay screen. 202, then 203 again. And what is your desired final result? Is it mainly about sliding abrasion or do we want to improve the flow and be more resistant to cavitation? I would argue that those are probably the main issues. There are two unique codes that explain why I’ll move from 202 to 203 or the other way around.



QUESTION:
We have that new 101 HT product, right, which is a high-temperature version of our regular metal repair. Is there a 201HT in development?
 
ANSWER: Yes. So, think about it this way: if our paste-grade materials are the 201 because they have ceramic in them or the 101 because they can be totally machined, then that’s fine. But if you or someone else comes to Chris and says, “Hey, this pump or this piece of process equipment is running at 300 degrees Fahrenheit,” you know, full.
 
Immersion—well, that’s not going to work for these other paste-grade materials, but the filler material, OK, that paste-grade material in this case might be the 101 XHT. I need to fill in the gaps with a plate bond. No matter what that is, 101 XHT, it will be the pace grade for that application. And then there’s 202203, which we’ve already talked about. It’s good for pumps and for regular operating temperatures. However, again, you tell me about this stripper. This other asset is working at high temperatures, between 350 and 300 degrees and 200 degrees. Oh, well, in this particular case, we’re going to go to that brushable ceramic coating that’s suitable for high temperature, and that’s going to be that tool, the 207 in that particular case.



QUESTION:
What’s the biggest mistake you see people make when applying the 200 series that ends up hurting performance?
 
ANSWER: Is this going to be surface prep? I mean, you know, the good thing is that it has to be it, right? We constantly attempt to cut shortcuts to get it back into service as soon as possible. Also, it might not have been left to cure long enough. You know that downtime costs money, and it can cost a lot of money. We would like to have that back in use as soon as possible. Tell us that this has to hold on for a few more months until we get to a shutdown because we. You probably have a substance that would work better for that. Sure, if you need it that quickly. But we have to execute the steps if you want a service life of 10, 15, or 20 years. We have to do it, right? So that’s going to be a rough blast. Making the sharp edges less sharp. All those places where, you know, coatings have failed in the past. This technique is going to make coatings fail. That’s because we attempt to get things done quickly.
 
Each of our coatings, each of our materials. They have a technical data sheet that goes step by step, and it says, “For best results, here’s what we recommend.”
 
Chris said that a client had a waste pump and that it was kept hot where it was pumping from. We had sold the supplies to it, which were actually the 300 series, 301 and 302, to fix a segment of the pipe in the beginning. At the beginning of the pipe, the flare temperature was much greater than the flare, like the temperature in the middle of the pipe. So it didn’t really fail, but it didn’t do what they thought it would do. And I guess we ended up selling them some 101 XHT for that job since there were only a few pinholes in the sewage pipe and they said, “Hey, we’re going to replace this in two years.” So we just need something that will keep it from leaking today.



QUESTION:
How realistic are these repairs to perform in the field versus in a shop environment?
 
ANSWER: It’s going to be harder in a field, right? Because you’re limited, you know, the temps around you might be different, right? You know, and everything else, but is it possible to accomplish it 100%? Of course. Yes. So, once again, please let us know what your limits are and where you are. For example, if you’re in a sump, we can warm it up and do all sorts of things. We’ll do our best to give you the best advice for that specific application and make it as successful as possible for us.

A different way to think about Corrosion Control in Maintenance. S2S Product Line from Valkyrie Enterprises

Who It’s For

This session is useful for:

  • Fleet Managers

  • Equipment Managers

  • Machinery Managers

  • Asset Protection


About the Speaker

A different way to think about Corrosion Control in Maintenance. S2S Product Line from Valkyrie Enterprises.

Most corrosion doesn’t occur in laboratories. It occurs on a real-world structure like the picture that’s in the slide. This is actually a picture of a bridge that an engineer sent to me that he was taking a look at, and he wanted to make sure that whatever they were doing was the right thing that they were doing, but they had some constraints that they couldn’t work around. A lot of times when you take a look at the situation that’s in the picture, you can’t do perfect surface preparation, or maybe you don’t have the downtime and can’t close the structure. Or maybe you just don’t have the funding at that present time to do it.


Why Traditional Coatings Struggle in Maintenance:

A lot of times the specification is written around applying traditional coating systems to new steel construction. A lot of times it depends on something like a commercial blast cleaning or maybe even something that’s more critical, like near white or white, where they need an anchor profile, typically two to four mils or something like that. Their corrosion-resistant properties are dependent on how well they actually can adhere to a mechanically prepared surface, typically abrasive glass cleaning. And lots of times they’re sensitive to moisture, surface contamination, salt contamination, and those kinds of things.

What S2S offers is a different approach:

It’s not to replace traditional coding systems. They offer some unique solutions to difficult situations where maybe you can’t abrasive blast clean for any one of a number of reasons, or you don’t have the ability to spray apply a coating.
  • Penetrates and migrates into rust, seams, pits and surface irregularities where corrosion begins.
  • Displaces moisture from steel surfaces
  • Combines corrosion inhibition with flexible barrier protection
  • Not dependent on perfect surface preparation ion for performance
The Valkyrie Corrosion Shield line of products is actually our workhorse line of liquids and the idea here is they they provide extended corrosion protection, long-term corrosion protection to steel, aluminum, different kinds of metallic surfaces. They come in different thicknesses based on how long-term corrosion protection you really need and what kind of items, like salt, fog, resistance, and cyclic corrosion testing, you need. Whitewater flow code is another example of something that’s very unique. If you’ve ever tried to prepare a surface and coat a surface that requires confined space entry, you know it’s very, very unique, can be very costly, and can be very dangerous. Valkyrie offers coating systems, especially this void and router flow code, where you don’t need to have confined space entry to make the coding system work. We’ve used it on, you know, certainly lots of builders and void spaces on barges and ships, but also on unique applications like monopiles for offshore wind towers and structural supports for offshore oil platforms. And then at the other end of the scale, we make products similar to the dielectric spray, which has tremendous insulative qualities. It comes in an aerosol and is used on dielectric components, circuit boxes, and battery terminals, and the idea is that it’s a substitute for dielectric grease. It’s easy to apply; if you need to remove it, it’s super easy to remove and much easier than the alternative.

Where this approach works best:

The Valkyrie S2S products fit into multiple industries. We grew up in the marine business. S2S has been in business since 2004, and their primary focus was marine when we started, and they have a tremendous relationship with the US military, especially the Department of Navy, but we’ve also expanded to bridges and highways, different kinds of construction equipment, and anything that requires either long-term or short-term corrosion protection. The common thread between all of them is generally in-service steel or other metals that require maintenance so that they don’t corrode, or you want to stop the corrosion, not just simply convert it from rust into something else, where you have moisture or salt exposure and you don’t have the ability to do outstanding surface preparation at that time.

How S2S Fits into Corrosion Management:

  • Compliments traditional costing systems

  • Addresses corrosion challenges where traditional coating systems struggle

  • Supports maintenance without full shutdown.

S2S doesn’t replace traditional coating systems. It extends asset life where mechanical adhesion-based systems struggle.

Q&A Highlights

From what you’ve seen in the field, where does S2S actually save the most money? Labor reduction, extended inspection intervals, or reduced rework?
Where it works best is where you’ve got areas that are, well, I’m going to break it into two or three different things. Let’s talk about areas where you can abrasive blast clean, but you’ve still got corroding steel. I’m going to make it up, but let’s say you’re in a saltwater marine environment close to the ocean and you’re doing structural steel on a bridge. Now, while S2S isn’t going to provide aesthetic value like, probably, a polyurethane on the steel where you can’t abrasive blast clean, it’s a simple application. You knock off the loose rust and make sure that it is clean, and it doesn’t even have to dry. You can then apply the product with a spray, brush, roller, or whatever it takes. You know you with some of the items you can flood coat if you want. So long-term corrosion protection, absolutely. The beauty of it is. Let’s say down the road when you have the funding and you want to paint it, how do I remove it? What’s the next maintenance site? With a high-pH detergent, something like Simple Green or one of the products that is out there, you can certainly remove it with warm water and a high-pH detergent and abrasive glass, clean it, and put on there whatever you want to do later on.

It says if someone is evaluating this against a traditional coding system, what scenario makes S2S the obvious choice, and where could you say it’s not the right fit?
It’s not the right fit for most kinds. Well, any kind of immersion in a liquid, OK. And I don’t mean water, but let’s say, for the sake of example, you’ve got a, you know, sour crude oil or gasoline or something like that. Absolutely not. But where it does work very, very well is where you’ve got a situation where I need to provide long-term corrosion protection. I want to do it with my own plant maintenance personnel that can’t use abrasive glass cleaner, don’t want to, don’t have the time, or whatever. It may be, and I mean a long-term corrosion protection, in that that kind of scenario works tremendously well. The other thing is we make anti-corrosion tapes. If I need to tape-wrap something in paste, I can have corrosion resistance that will last for decades depending on the application and how I want to do it.

Have you seen or heard of it causing any CP interference? Does it have NSF or NSF 61?
No, none at all

Gridguard HD Plus

Who It’s For

This session is useful for:

  • Pipeline owners, engineers, corrosion teams, and inspectors evaluating rock shield performance and CP compatibility 

  • Contractors and crews who want easier handling, fewer cold-weather headaches, and faster lowering operations 


About the Speaker

Jamie Blanco has worked closely with installers and engineers to translate real-world challenges into practical solutions. She has been with JDR Enterprises for nine years and played a key role in the development and approval of Gridguard HD Plus, serving as a manufacturer’s representative focused on advancing rock shield performance and adoption.

Gridguard is manufactured in Madison, Georgia.


Why Rock Shield Matters

Rock shield is used to:

  • Protect the coating from rock impact during backfill—and ideally continue that protection after burial

  • Help prevent coating damage that can lead to long-term corrosion 

  • Support the overall corrosion-control system, including cathodic protection 

A “good” rock shield shouldn’t only survive the backfill—it should protect the coating long-term without becoming a contributor to coating failure risks


Common Challenges (Field + Engineering)

Field challenges crews deal with

  • Heavy rolls, moisture retention, freezing, and handling problems that slow installation and raise safety concerns 

  • Difficult use with cradles/rollers leading to lost time and money

Engineering concerns

  • Cathodic protection compatibility is one of the first questions raised with rock shield selection 

  • Thick materials that hold water, abrasion risk against coatings, and unvetted/untested products being used in the field 


What to Ask Before You Approve Any Rock Shield

Use these as a quick checklist for your next spec review:

  • Does the design eliminate void spaces where small fragments can get trapped? 

  • Has it been tested for CP flow during burial and compaction (not just unburied tests)? 

  • Does installation require heat welding—and if so, what are the risks of heat near the coating? 

  • Does it retain moisture or freeze in cold weather, creating handling delays? 


Gridguard HD Plus Highlights (At-a-Glance)

Designed for engineering + corrosion teams

  • 6 oz geotextile backing bonded to a bidirectional extruded poly for impact resistance 

  • Geotextile backing intended to assist CP and “will not shield,” with test reports available 

  • Strength comes from the bidirectional poly structure, not “just thickness” 

  • Helps reduce abrasion on the coating and allows water/fines to move around the pipe

  • Eliminates void space concerns (fragment trapping) 

Built for field productivity

  • Light weight: ~0.41 lbs/sq ft (about half of traditional rock shield, per the talk) 

  • Longer rolls: 50 ft vs. 30 ft traditional 

  • Can be used in rollers/cradles without bunching or tearing, speeding lowering operations 

  • Uses less tape (often about half) and can reduce wrap intervals (commonly up to ~12–18″) 

  • Cold-weather flexibility tested to -40°F to -50°F (including wet/frozen conditioning) 

  • UV protection: ~1.5 years built in, plus additional protection from carbon-black wrapping 

  • Made with up to 24% recycled materials 


“Avoid This” — Most Common Field Mistakes

Jamie called out two common install errors that can create downstream issues:

  1. Lip installed “up” instead of down — the lip should be down and wrapped toward the bottom of the pipeline to reduce fragment entry. 

  2. Fabric installed outward — ensure the geotextile is against the coating (not facing out). 


Q&A Highlights

Other applications discussed:
Gridguard material has been used (or explored) in applications beyond pipeline—including under tanks with anodes, under liners, and behind concrete in other projects. 

Hazardous waste / liner cell protection:
A question came up about using it for additional impact resistance in new hazardous waste dump cells where crews currently use geo fabric prior to liners. 

High temperature rating:
When asked about “top temp,” Jamie noted there are melt-point values available (start-to-melt vs. fully-melted), and she can provide those specifics.
