This is a granulated asphalt cap sheet. You can find it at any roofing retailer or big box store in the roofing section. No particular brand, but ask the sales personnel what they might recommend in-store.

We have many distributors throughout Pennsylvania. You can find our list of distributors on our website under "Where to Buy". Be sure to call them ahead of time to make sure they have the product you are looking for in stock before making the trip! See this link: www.karnakcorp.com/store-locator

This is for emergency repairs. When it comes time to put a two-layer system, you can always overlay that on top of this (as long as it is clean and dry, so as not to trap moisture and risk blisters in the future).

We're always here for the feedback!

Unfortunately our coatings are not designed nor are tested for this application. As a result, we cannot recommend your proposal as a solution.

We love to hear it!

Nice! Our aluminum coatings stand up to the test of time and weathering

Which product do you have, and which do you need? Feel free to call our Technical department for specific questions

You can visit www.karnakcorp.com, and under the Resources tab you can find both Karnak University and also you can contact us for the Karnak Qualified Applicator program training. We look forward to hearing from you!

Yes, using an entire sheet of Mod Bit across the wall would work great in your situation! Please ensure there are no masonry cracks on the wall or coping that will allow water to get in behind your new membrane. Feel free to call our Technical department for specific questions.

This product, 298 Alumin-R is highly rubberized and wears much slower than the 97. The 298 will last around 10 to 12 years, while the 97 lasts around 5 to 7 years before recoating should occur. The 97 has fibers in it, while the 298 does not. Hope that helps! Feel free to call our technical department if you have any further questions at 800 526 4236.

@KARNAKroofcoatings I'm looking to patxh my roof with Karnak 19 ultra.. how long do I have to wait before I apply the karnak 298 coating over it?

Unfortunately you cannot. This is just an adhesive for roof membrane to roof membrane. Always be sure to follow membrane manufacturers requirements when installing. Feel free to call our technical department with any other questions.

Can always use modified!

We do not know the alternative at big box stores, but if you visit our website at karnakcorp.com, you use our Store Locator feature to find a distribution center near you.

That's another option!

We'd be very sorry to hear that...

Yes, you can apply this product (Karnak 97 Aluminum coating) to your mod bit roof. It will slow down the granular loss when applied. A better solution would be to apply our 220 Fibered Emulsion first before the coating. This will end up with a longer lasting, better result.

Great point!

671 Karna-Seal provides 400% elongation in a variety of hot and cold weather types, throughout weather changes

This product (Karnak 66) is as true mod bit adhesive, and will work better in this example than 19 Ultra.

This tape is a foil-backed butyl tape.

We are located in northern New Jersey, give us a call if you need anything!

Glad you found it helpful!

Thanks for sharing this insight!

You can find this at many local roofing distributors, but unfortunately it is not available in a quart size.

It's a great option as an aluminum reflective coating! But a better performing one would be our 298 Alumin-R.

In our experience, this is not true as long as the roof system is fully dry before application. This is why we recommend a moisture survey before coating.

Vamos a intentar amigo. Gracias por apoyarnos.

Asphalt coatings incorporate a softer melting point asphalt than traditional hot-applied asphalt. Therefore, when they cure, maintain a somewhat soft, ductile, and pliable surface.

This application is for the installation of a new roofing membrane, so it will last as long as the membrane on top lasts. While we do not manufacture or sell SBS roofing membranes, most manufacturers will give a warranty of 10 to 15 years depending on different factors.

Interesting! We have not yet seen this application. We recommend you try it first on a small inconspicuous section of the wall as a test area. We'd love to hear your results.

Our 404 and 501 system would work fine as long as the slope is over 2/12. This means, for every 12 inches the roof moves horizontally, it goes down at least 2 inches.

Hope you found this helpful!

Yes, this product will definitely help with that!

Karnak is available for sale in California. Please visit our website at www.karnakcorp.com to see your options and contact our local sales rep.

Move

Yes, it is to make the product easier to apply, but by lowering the viscosity.

All of our asphalt-based repair products will skin over in 24 hours. However, once 19 is applied to the clean and dry surface, it could rain within a minute and will not wash away.

He also gets his pastrami from there as well

Glad you liked it!

Glad you enjoyed! We're only a phone call away if you ever need technical advice

No, it is not. We have coated airports with both aluminum and white reflective coatings with great success.

That's another option!

When applied, it is waterproof immediately, but reaches its ultimate adhesive strength in 28 days.

@@KARNAKroofcoatings28 days??? Torch down is instantaneous!

No, this is a reflective coating only, with no waterproofing properties.

That's definitely a major part of it!

No asbestos in this product, we are happy to report!

2 years, if you're lucky.

That would depend on many factors, including weather, frost/heave, underlying substrate, and building movement.

Thanks!
