Waterproofing Systems - Acrylic or Urethane Membranes?

July 3, 2017

Over the past two decades, there have been technological advances in waterproofing materials, including more advanced membrane materials which seek to overcome shortcomings in older methods like PVC (Polyvinyl Chloride) and HDPE (High-Density Polyethylene). New technology in waterproof membranes relies on polymer-based materials that are extremely adhesive to create a seamless barrier around the outside of a structure. Acrylic coatings are water-based and among the most popular materials on the market for commercial projects. Urethane coatings are solvent-based and while they have some of the same advantages as acrylics, some features are different.

 

Acrylic coating advantages:

· Fewer odor and toxin emissions

· Lower price tag

· Easy to clean (with soap and water)

· Good color retention

· Shiny and polished; great for concrete

· Resistant to UV damage

 

Urethane coating advantages:

· Fewer odor and toxin emissions

· Shiny and polished

· Strong resistance to traffic

· Toughness, flexibility, and less risk of chipping over time

· Less vulnerability to spotting and discoloration

· Ability to level out well thus making it a great product for metal

· Ability to adhere to previous finishes

· No susceptibility to water damage
