Advanced Polyurea Waterproofing & Coating Systems

Polyurea coating technology is a newer and more advanced method than traditional waterproofing and protective coating technologies.

It isn't a new technology, however. It has been in use for nearly three decades.

This technology relies on the reaction between an isocyanate and an amine mixture. It can be either aromatic or aliphatic. This rapid reaction can be completed in a matter of seconds. Therefore, it is necessary to use specialized mixing equipment and equipment for a special application crew.

Major advantages-properties of all Polyurea based products

  • Ultra-fast curing. Traditional coatings take longer to return to service or for further processing. The gel time takes only seconds and allows for foot traffic within a matter of minutes. This means that the facility can be returned to use in as little as one day.
  • Excellent chemical resistance and extraordinary mechanical properties like elongation and tensile strength, tear resistance, crack-bridging ability, and abrasion resistance. When it comes to physical properties, Polyurea is the best coating.
  • Application may cause sensitivity to humidity. Polyurea's hydrolytic stability means that relative humidity and residual moisture have little or no effect on the adhesion or coating performance.
  • Temperature variations can affect thermal stability. Weather changes have little effect on coating performance and adhesion properties.
  • Solvent-freeIt is made up of a 100% solids formulation. Polyurea products can be considered to be environmentally friendly.
  • Apply quickly with a two-component, high pressure, and temperature spray machine.
  • After curing, monolithic, seamless membrane. Polyurea membranes are resistant to high mechanical and chemical loads. These membranes can also be permeable to vapor, which prevents moisture accumulation.
  • Also applicable to vertical and curved surfaces, you can coat intricate architectural details and structures in any thickness you like without worrying about sagging.
  • The thickness of applications is almost limitless one go.
  • Good adhesion you can use various substrates (concrete and metals, as well as wood, etc.), even under extreme temperatures and high humidity.


Waterproofing Structures

Protecting against water damage is one of the major advantages of Polyurea as well as polyurethane. Water cannot penetrate the concrete or wood surface by creating a leak-proof barrier. This prevents water from absorbing into the underlying surface, such as concrete or wood, and can even be used to prevent rotting, rusting, or warping.

Be aware of the following areas:

The application of the correct waterproofing treatment to the environment is a major issue in construction. It should last for many years. These are some examples:

  • Foundations and basements
  • Landscape design with water
  • Wall-floor crevices

How to Waterproof Walls

Too often, water seeps through the crack between the wall and the floor. Rain on a porch or water from a factory lunchroom, liquids, and microorganisms can seep under the trim and behind walls. They can cause damage to the structure and create unhealthy environments.

ArmorThane can create a seamless membrane using chamfer molding attached to the floor and coating partway up walls. The cracks can be sealed by two little seams replacing the main one. You can also learn to attach outdoor siding to wood decks to prevent water from entering the wall.

Leak Repair in Basements/Foundations

It is important to determine the source of the leak and the extent of the flooding in the structure. This will help you decide which repair or preventive measures are most appropriate. First, repair cracks. Then, professional application of one of ArmorThane's polyurethane, Polyurea, or combination coatings to the outside, interior, or both is made. These spray-on coatings are strong enough to create a waterproof barrier that will prevent further deterioration.

Sealing the foundation and walls of the building during construction is the best option. This will ensure a smooth application and prevent future damage.


Weatherproofing to Increase Structural Strength

ArmorThane coatings with Polyurea make surfaces more resistant to severe weather like tornadoes, hurricanes, and straight-line winds. These powerful winds and ground shifts can easily break, crack, and bend wood, metal, and concrete. Polyurea bonds outdoor surfaces such as floors, walkways, and decks with high tensile strengths. The material absorbs impact and stretches to hold the structure together.

Polyurea protects against hail damage and flying debris during storms. Damage can be avoided or minimized by strengthening the surface.


ArmorFoam provides additional protection by strengthening walls and ceilings made of metal and wood structures. Closed-cell sprayed insulation fills cracks and crevices with foam. The foam then hardens to increase structural strength. This insulation is twice as energy-efficient as traditional insulation and has twice the R-value rating.
