What Is Polyurea?

A pure polyurea coating / elastomer is derived from the reaction product of a polyisocyanate component and an amine-terminated resin blend.

For reference purposes, a polyurethane / polyurea hybrid coating / elastomer is the reaction product of a polyisocyanate component and a resin blend component. The resin blend may be made up of blends of amine-terminated and / or hydroxyl-terminated polymer resins.

Polyurea high-build, fast-set, spray-applied elastomers provide significant protection to various metal/steel, wood, concrete, fiberglass, plastic, rubber, urethane foam, and many other substrates.

Polyurea coating systems are resistant to water and petroleum-based chemicals, such as gasoline, hydraulic fluid, diesel fuel, motor oil, MTB, toluene, sulfuric acid, hydrochloric acid, and caustic chemicals such as sodium hydroxide, potassium hydroxide and hydrogen sulfide.

Over the past 15 years or more, polyurea has become the No. 1 choice in resolving many issues in the coating industry. Its fast cure time, excellent adhesion, abrasion and corrosion resistance, strong durable finish and waterproofing capabilities makes polyurea the leading solution.


 

     

 

 

Polyurea Used in Waterproofing

Foundation waterproofing is an important consideration when building. Many buildings have been damp-proofed instead of waterproofed. To effectively protect a basement from water infiltration it must be properly waterproofed.

Mold grows in environments where constant streams of moisture occurs. Moisture come

through water being carried in soil surround the foundation. Waterproofing is the only way to permanently stop water and vapors from entering foundation walls. Spray-on polyurea systems work well when it comes to sealing off the pores of concrete walls.

Polyurea forms a water resistant, seamless monolithic coating for waterproofing slabs, wooden decks, roofs, and other surfaces to prevent leaks, rust, corrosion and water damage.

It must be specified and installed in combination with proper surface preparation and primers, correct manufacturer’s material formulation, proper equipment, quality control inspection and trained applicators.

Polyurea can be mixed with aggregates to achieve the desired skid resistant surface.

All systems can be installed to meet the ADA requirements for slip resistance. Polyurea coating systems can be textured through the use of silica sand, polypropylene beads or aluminum oxide. In general, a smaller grade aggregate can be incorporated into the coating while larger aggregate must be broadcast and back rolled. The broadcast technique will leave variation in texture. Broadcast systems are naturally course and can be made smoother through the use of additional topcoat materials.

 

 

Polyurea has been successfully used as primary and secondary containment in many industries such as oil & gas, potable water, waste water, sewage, fish hatcheries, and piping conduit interiors.

The term primary containment refers to the first level of containment, usually storage tanks, pipes or retention ponds that come in direct contact with the substance or material being stored. Primary containment coatings play an important role with protecting structures to make them last longer and more importantly protecting the environment against leaks or spills of potentially harmful materials.

Its strong water and chemical resistance properties make polyurea an excellent selection for thoroughly containing many liquids associated with containment breach. Containment is the key function of the polyurea coating, but it also protects the containment substrate from corrosion caused by harsh acidic or caustic chemicals or environmental conditions.

Today, storage tanks are often highly regulated with regular inspections, reports written and certifications earned. When primary and secondary containment tanks reach the end of their lifespan, polyurea can bring them back to a certified condition. Because secondary containment is a safety backup, it is just as important to have a strong resilient coating. Polyurea forms a seamless membrane which can be applied to many surfaces and can conform to any shape to eliminate the risk of the liner leaking. Its elongation properties allow for movement of metal, concrete and earthen substrate without tearing the monolithic barrier.

Emulsion Waterproofing & Maintenance Coating System

Asphalt Emulsion is a premium, versatile coating for the protection of roofing materials, metal, and masonry surfaces. Solvent-free, it is made from asphalt emulsified with bentonite clay and water. Asphalt Emulsion is cold-applied, nonflammable while wet, corrosion- resistant, and waterproof when dry. Asphalt Emulsion will not crack, "alligator," run, or sag under extreme weather conditions. It resists most corrosive fumes and spray.

Features

• Best-value, versatile protective roof and waterproofing coating

• Solvent-free, non-fibered black asphalt, waterproof, “non-alligatoring”

• For concrete, masonry, steel tanks/coating composition, metal and smooth-surface built-up roofs

     

 

Emulsion Maintenance Coating System

Emulsion can be sprayed applied over existing Built up asphalt membranes, metal roofing, concrete decking, and in some cases single-ply membranes. The process is fairly simple and cost efficient as emulsion can be delivered strait to the job site in tankers and pumped in place with specialty high volume pumps.

A typical emulsion maintenance system is made up of 3 layers. Layer one will typically receive 1-layer of reinforced polyester fabric set directly into the freshly sprayed emulsion. Once the base layer is cured 24-48 hours the second layer is applied. The second layer is made up emulsion being sprayed in place at a typical rate of 9 gallons per 100 square feet. By using a special gun fiberglass roving is copped and fanned into the emulsion as it is sprayed into place. At this stage your roof is water tight the emulsion has transformed it into a smooth black roof that is ready for years of protection. Typically contractors will then apply a reflective roof coating over the emulsion by either spray applying a aluminum or acrylic latex paint to help reflect the heat.

Acrylic & Urethane Maintenance coating system

Acrylic Latex & Urethane coatings can be sprayed or roll applied over existing Built up asphalt membranes, metal roofing, concrete decking, and single-ply membranes. With a handful of quality manufactures producing specialty products for almost any application the possibilities are almost endless.

Acrylic latex & Urethane coatings can be used over:

- Emulsion as a reflective top coat to help keep the roof surface cool.

- Polyurethane foam as a protective top coat against damaging UV rays

- As a maintenance system on older roofs to extend their serviceable life.

Epoxy & Urethane deck & floor coatings for pedestrian and auto applications


 

Epoxy

100% solids epoxy. (what this means is that there is no cheap solvents or water used as fillers). A 100% solids epoxy is truly the best floor coating available today. An epoxy is a 2 part coating that you mix ʻAʼ & ʻB” together. Once mixed, a special, safe chemical reaction occurs which makes it super hard when it cures.

Factories, manufacturing facilities, hospitals, and the US Government all use 100% solids epoxies due to their low odor, ease of use, and extremely long life. When applied properly it is approximately 5 times thicker than standard floor paint or cheap ʻhome centerʼ epoxies. (Yes, those epoxies come in nice packages, but can you really truly expect a long lasting floor for less than $75.00?).


 

Urethane

Urethanes on the other hand are more pliable and can be installed in multiple coats. Urethanes are used more in applications that will require the material to stretch and move with the structure like over wood decking but can also be used as a floor covering and waterproofer for a multitude of applications.  With thousands of color schemes to chose from and products designed for almost any application it would be hard not to find the look and finish you desire.
