Waterproofing Paint, Coatings or Membrane - DIY Waterproofing-Liquid Rubber Sealant

Waterproofing Paint, Coatings or Membrane

Waterproof paint is NOT the same as a waterproofing membrane.

  • Waterproofing membranes and waterproof paint have a similar objective – minimizing the travel of water through a substance.
  • However, there are major differences.
  • The American Concrete Institute (ACI 515.1) defines:
    "waterproofing as a treatment of a surface or structure to resist the passage of water under hydrostatic pressure, whereas damp proofing is defined as a treatment of a surface or structure to resist the passage of water in the absence of hydrostatic pressure." 

To permanently stop water and water vapor from entering a structure you need to waterproof with a MEMBRANE

  • Waterproof roof paint does not have the durability, strength, protection, UV reflectivity, and waterproofing capabilities of a roof membrane.
  • Paint cannot withstand the typical elements a roof endures - it becomes brittle and will peel, chip and crack.
  • The polymers used in a waterproofing membranes allow for superior bondage, ensures durability and waterproof protection to structures.
  • The elastomeric properties of membranes allow flexibility and ability to bridge over surfaces.
  • Elastomeric membranes are impermeable to water, chemical vapors and subterranean gases.

Liquid Rubber Membranes

Liquid Applied Waterproofing Membranes are the new generation of elastomeric waterproofing.
