Polyurea

We believe in matching chemistry to exposure, not the other way around.

Most coating failures trace back to a mismatch: a rigid film on a moving substrate, an aromatic topcoat in full sun, or a fast-set elastomer sprayed over damp, unprepared concrete. This site explains how the major polymer systems behave so you can ask better questions before a single drum is opened.

About this guide

PrepSurface preparation sets the ceiling on adhesion.

Film buildThickness is specified, measured and recorded.

Epoxy

What we cover

FEATURED SERVICES.

All applications

System selection

Matching chemistry to abrasion, chemical, thermal and UV exposure.

Specification support

Prep standards, film thickness and inspection points to write into a spec.

Polyurea and hybrid systems

Fast-set elastomers for waterproofing, linings and impact protection.

Recoat and repair planning

Assessing an existing coating before deciding to repair, overcoat or remove it.

Where it goes

SELECTED APPLICATIONS.

Find an applicator

Secondary containment

Seamless elastomeric linings for berms, pits and tank farms where chemical exposure and crack-bridging both matter.

Steel & structures

Barrier systems over blasted steel, with primer selection and film build driving service life.

Roofs & decks

Fast-return waterproofing membranes, topcoated with aliphatic chemistry where UV color stability matters.

Concrete floors & pits

Moisture testing, profile and primer choice before any film goes down on concrete.

How we help

The guidance we offer is built around your substrate and schedule.

Every guide on this site is educational. When a project is ready for pricing, ArmorThane and its independent applicators handle quotes, equipment and installation.

The lineup

MEET THE CHEMISTRIES.

Pure polyurea

Sets in seconds, highly elastic, tolerant of cold application.

Hybrid polyurea

Blended chemistry trading some properties for cost or working time.

Polyurethane

Versatile elastomers and topcoats; aliphatic grades hold color in sunlight.

Epoxy

Rigid, strong adhesion to concrete and steel, commonly used as primer.

Questions

COMMON QUESTIONS.

How do I choose between epoxy and polyurea?

Epoxy is rigid and bonds strongly to concrete, while polyurea is elastomeric and sets in seconds. Movement, return-to-service time and UV exposure usually decide it.

What is a hybrid polyurea?

A system that blends polyurea and polyurethane chemistry in the resin side. Hybrids trade some properties for cost or a longer working time.

Why does the same product perform differently on two jobs?

Surface preparation, substrate moisture, ambient conditions and applicator skill vary from site to site, and they often matter as much as the product.

What should a coating spec include?

Surface prep standard, primer, product, dry film thickness, cure conditions, inspection hold points and repair procedure.

Can a new coating go over an old one?

Sometimes. The old coating must be well-bonded and compatible; an adhesion test on site is the safest way to know.

Who should apply polyurea?

Trained applicators with heated plural-component equipment, since ratio and temperature control are essential.
