Frequently Asked Questions about CeramaTherm

How can CeramaTherm insulate so well when it is so thin?

The coating is made with nanoceramics and aerogel. It has the highest insulation value that we know of. At ten mils (0.25 mm) thickness, the K value is 0.02 W/mK – the thermal transfer is near zero, possibly the closest you can get material to a vacuum.

What is K-Value? K-value indicates the ability of a material to conduct heat. Materials with low thermal conductivity do not easily allow heat energy to pass through.

If I add more coats, will that provide even more insulation value?

Yes. Once the coating has dried for two hours, you can recoat and build up the coating for your needs.

NOTE: It is important to let the coating fully cure for at least five days before submersing in water.

What is the coverage rate?

120 square feet per gallon at ten mils dry, applied at 13.3 mils wet, depending upon the substrate.

Note:  CeramaTherm is sold in 25-gallon kits. Each kit covers approximately 3000 square feet when properly applied. Please be sure to carefully read the Technical Data Sheet, available in the Documentation section on the site.

What can CeramaTherm be used for?

CeramaTherm is a highly durable coating used anywhere you want thin film insulation. It is self-priming to just about any surface. It can be used for above and below water, roofs, walls, metal, interior and exterior equipment, buildings, vehicles, trailers, reefer trucks, barns, housing, etc.   

It can also be used in planes, firewalls, boat engine bays, and other locations where space is tight and where you need extreme insulation with minimum bulk.

Is CeramaTherm waterproof?

CeramaTherm is waterproof and can be applied directly to metal, PVC, Concrete, EPDM, cap-sheet, wood, stucco, sheetrock, and virtually any substrate. CeramaTherm adheres to practically all surfaces. It maintains remarkable flexibility to prevent cracking.

How do I tint CeramaTherm?
  • CeramaTherm is a 2-part epoxy coating. Part A is the activator. Part B is what you tint.
  • Go to Sherman Williams (or similar) and select a WATER-BASED – NOT(!) an Epoxy-based tint.
  • They will tell you it needs to be Epoxy-based, which is wrong for this product’s chemistry, and will trash the coating.
  • Select a lighter base color and add the tint vials at product usage time.  The product contains a lot of whiteners, and if you select too dark a coating, you will be fighting the whitener and not like the results.
I have multiple different types of substrate that I want to go over. Is this an issue?

You can use it on almost any clean, prepared surface. But, CeramaTherm is not recommended to be applied directly to Teflon, high-plasticized vinyl, polyethylene, and/or silicone rubber. However, utilizing our BX520HT primer can even be applied to polyethylene.

What are CeramaTherm's Sound Deadening properties?

CeramaTherm provides up to 68% sound reduction and can be used inside or out. It is ideal to use on the inside of vehicles when doing restoration.

It is often used on the walls between suites in hotels or apartments.

It is extremely good for renovating older buildings where you do not have the time or money to spend removing the old walls and insulation.

Will CeramaTherm still work if it gets dirty or is painted over?

CeramaTherm is highly durable. It can get dirty and lose its reflectivity, but it will still insulate due to the type of components that have been incorporated into the product. 

We want to use CeramaTherm on our Reefer trucks to prevent heat transfer, save energy, and save weight. What are your recommendations?

For Reefer trailers, CeramaTherm adheres to practically all surfaces with remarkable flexibility. Use the CeramaTherm to coat the top outside of the roof, interior walls & ceiling, and the underside of the trailer floor. This keeps the road heat from radiating into the box and provides a highly durable waterproof coating. Do not coat the interior floor, as using forklifts and such (for loading and unloading) tends to tear up the finish.

One of my team works for a Telecom industry that has 1,000’s of Telecom towers. They have battery boxes that have A/C units on them to keep the batteries cool. He’s wanting to use the CeramaTherm on the boxes and is worried about the surface not being properly prepared, it could be slightly dusty as wind is always blowing. They can wipe, brush and take a wire brush to the surface, but because they are so high up the tower, he doesn’t know that the surface could be completely free from dust. Do you see this being an issue?

This should not pose any problem. Ensure you remove as much of the dust as possible as the coating is being applied,  enabling the coating to bond to as-solid-a-substrate as much as possible.

What is the kit shelf life?
  • The products shelf is known to be at least 1 year.
  • CeramaTherm is a 2-part epoxy coating. Part A is the activator. Part B is the coating material.
  • Part B is designed to off-gas as it cures, and if you open the product too soon, or if the rubber gasket at the top of the container dries out or leaks, some of the solvent will evaporate. 
  • This will cause Part B to become stiff. If Part B is too stiff, this can easily be resolved by adding up to a coffee-cup volume of MEK or similar solvent/alcohol to the container and mixing it very well, before you add any tint or the Part A activator.
Where is CeramaTherm made?

CeramaTherm is made in the USA.

We build pools, we use prefab panels to make the swimming pool shape, plastercrete is then applied. As CeramaTherm is waterproof, can we apply it over the cured plastercrete to seal it. And once it is dry, can we apply ceramic tile on top of the CeramaTherm. Would there be any issues for sticking?

Ensure the CeramaTherm is at ten mil DFT thickness above the high points of plastercrete (applied 13.3 mils wet). As long as the CeramaTherm is fully cured, apply the ceramic tiles using a ceramic tile adhesive recommended for high moisture areas.

We have projects in different construction areas, how do we split up the containers?

The containers come as a 25-gallon kit. It equals five 5-gallon pails of Part B (each contains four gallons), and one 5-gallon pail of Part A, to be split between the 5 part B pails (very easy to do) – they can mix one pail at a time, or all five at once if the job size warrants it. To split into different job sites, ensure you mix part A well, following the precise instructions on this site or in the TDS sheet. Once mixed, you can split out what you need.

We have high humidity, and sometimes rain showers happen even when the sky is clear and blue, so it's not predictable. It says in the literature that the coating can be applied to damp surfaces. Are there any particular thoughts, comments or advice you would have in the application of CeramaTherm in that type of environment?

It should not be a problem at all – damp surfaces are ok – if it has just rained, sweep off standing water as best possible (allow it to dry to damp, if possible). Once the coating is sprayed onto the surface, rain showers will not harm the product and will continue to cure.

What kind of tape do you recommend to bridge gaps for roofs?

As long as the structure is solid, use UniTape Seam Tape or equivalent type fabric tape – being sure to use a width that allows at least a 7.5 cm/3″ overlap, or more on each side of the joint if there is much movement expected, then coat over with CeramaTherm.

We have an R/V Camper and 30’ Yacht that we are renovating, can we use ‘CeramaTherm AM’ for inside the walls?

This is an excellent use of the material. You can use it for insulation inside any vehicle and apply it on walls, floors, ceilings, inside doors, and on the firewall. It will save on weight, provide more usable space, and protect the substrate from corrosion, mold, and mildew. It will also allow your vehicle to be warmer in the winter and cooler in the summer. It will also reduce road noise considerably, reducing driver fatigue. You can apply this under the floor and wheel wells to reduce road noise and protect from exhaust and road heat. Please look at our other advanced Tecmari Nano Ceramic Products to keep your R/V and Yacht looking and performing their best.

What does a kit weigh?


The kit is designed to fit and be shipped on one pallet, and comprises six 5-gallon containers. A maximum of two kits can be shipped per pallet. We wrap these prior to shipment to ensure everything stays together.

  • Pallet size is generally 48″ x 42″  
  • Pallet and product weight for 1-  25gal kit —  ~306lbs / 166kg
  • Pallet and product weight for 2-  25gal kits — ~590lbs / 355kg

For container load sized orders

Here is the information for a 40 ft container

  • 20 pallets per layer x 2 layers = 40 pallets
  • Each pallet has 100 gallons, each pallet weights 1062 lbs including pallet
  • So 40 pallets x 100 gallons = 4000 gallons in a 40 ft container
  • Total payload = 42480 lbs. The maximum payload for a 40 ft container is 59200 lbs.

A 20 ft container would be half of the 40 ft container volume

For overseas shipments, we will work with your shipping company to ensure the content and weight are properly packed and constrained.
