EPDM Rubber vs Neoprene Liquid Rubber is a never-ending discussion amongst roofing contractors.

Both are synthetic rubbers and are commonly used in outdoor constructions.

However, its cost, benefits, and application guidelines are different.

Therefore, in this article, you will find the main characteristics between EPDM rubber vs Neoprene Liquid Rubber.

Read on!

EPDM Rubber: What is it?

Ethylene Propylene Diene Monomer (EPDM) is a synthetic rubber that results from a single bond molecular structure.

Above all, it has great resistance to acids, cold, heat, and ozone. 

In addition, it has excellent waterproofing, noise reduction properties, and you can use it as an electrical insulator.

Therefore its popularity includes the automotive, HVAC, and roofing industries.


  • Recovery from up to 600% elongation
  • Functions better in higher temperatures
  • Heat, coolant, steam, sunlight, ozone, and water-resistant
  • Popular for its electric and noise resistant


  • It’s the cheaper option
  • Swells if put in contact with petroleum oil, fluid, or solvent
  • EPDM roofing can also puncture fairly easily

Neoprene Liquid Rubber: What is it?

It is a superior fluid-applied rubber that combines the elastic properties of a modified latex with the waterproofing qualities of a highly refined Liquid Rubber.

Consequently, Instacoat Premium Products’ Neoprene Liquid Rubber technology is designed to form a waterproofing layer of protection over your roof.

As a result, it will completely stop any possible water leaks that could arise from the ponding water formed in the roofs during the rainy season.

EPDM Rubber vs Neoprene Liquid Rubber

Instacoat Premium Products’ Neoprene Liquid Rubber Technology


  • Ideal to use it as a top coat over existing roofing systems
  • The material is non-toxic, odorless, and non-flammable
  • Its average elongation is over 1,000%
  • It is a water-based material that contains no VOCs (Eco-Friendly)


  • It can only withstand temperatures of up to 225 degrees Fahrenheit
  • It is a more expensive solution
  • Vulnerable to aromatic and oxygenated solvents


As you can see, EPDM rubber and Neoprene Liquid Rubber are very similar roof restoration technologies, and both are optimal solutions for aging roofs.

However, the IPP Neoprene Liquid Rubber technology outperforms EPDM rubber’s benefits.
