Choose the Right Polyurethane Floor Coating
Fortis manufactures clear polyurethane coatings for concrete, timber, epoxy and decorative floors. Choose the system according to the substrate, expected traffic, chemical exposure, application conditions and required finish.
Fortis Coat 519 – Single-Pack Clear Polyurethane
Fortis Coat 519 is a moisture-curing, single-component clear polyurethane for prepared concrete, timber, grind-and-seal floors and decorative surfaces. Available in Gloss and Matt, it offers durable, UV-resistant protection without mixing a separate hardener.
Fortis Coat 526 – Water-Based Polyurethane
Fortis Coat 526 is a two-component, self-priming water-based polyurethane with ultra-low VOC and low odour. Suitable for concrete, timber and decorative surfaces, it is available in Gloss and Satin. Use Gloss for the first and build coats, followed by Gloss or Satin for the final finish.
Fortis Coat 527 – Premium Clear Polyurethane Topcoat
Fortis Coat 527 is a two-component solvent-based clear polyurethane topcoat for compatible epoxy flooring, decorative flake systems and demanding commercial floors. It provides excellent abrasion, wear, chemical and UV resistance.
Fortis PAP – Concrete Adhesion Promoter
Fortis PAP is a specialist adhesion promoter for difficult, high-quartz and siliceous concrete surfaces where additional adhesion is required before applying a compatible polyurethane coating. It does not replace correct mechanical surface preparation.

Product | System | Recommended Application |
|---|---|---|

Two-pack solvent-based PU | Epoxy, decorative flake and demanding commercial floors |
Polyurethane Over Epoxy & Decorative Flake Floors
A compatible clear polyurethane topcoat adds a protective wear layer over epoxy flooring while helping maintain the appearance of the underlying coating.
Fortis Coat 527 is recommended over compatible Fortis Coat 823 HS and decorative flake flooring systems where increased abrasion, wear and chemical resistance are required.
For projects requiring faster curing and reduced downtime, compare UltraSpart® 100 polyaspartic floor coating.
Garage Floors, Tyre Staining & Hot Tyre Pick-Up
For garage floors and automotive applications, consider vehicle traffic, tyre staining, hot tyre pick-up and chemical exposure when selecting a clear coating.
Tyre staining refers to discolouration caused by compounds transferred from vehicle tyres. Hot tyre pick-up involves loss of adhesion or lifting of the coating under hot tyres. These are different performance requirements.
Resistance depends on the complete coating system, surface preparation, curing conditions and service environment. Contact Fortis where tyre resistance is a critical specification.

Polyurethane Coatings FAQs
Which polyurethane floor coating should I choose?
Choose Fortis Coat 519 for single-pack clear protection of concrete and timber, Fortis Coat 526 for a low-odour water-based system, or Fortis Coat 527 for more demanding commercial flooring and compatible epoxy topcoats.
Can polyurethane be applied over epoxy flooring?
Yes. Fortis Coat 527 is suitable as a clear protective topcoat over compatible epoxy flooring, including correctly prepared Fortis Coat 823 HS systems.
Which polyurethane is best for decorative flake floors?
Fortis Coat 527 is recommended as a durable clear wear coat over compatible decorative flake floors. For faster curing, compare UltraSpart® 100.
What is the difference between Coat 519 and Coat 526?
Coat 519 is a single-pack moisture-curing polyurethane available in Gloss and Matt. Coat 526 is a two-component water-based polyurethane with ultra-low VOC and low odour, available in Gloss and Satin.
What is the difference between Coat 526 and Coat 527?
Coat 526 is a self-priming water-based system for suitable concrete and timber. Coat 527 is a solvent-based polyurethane topcoat for compatible epoxy, flake and more demanding commercial floors.
Which polyurethane coating is suitable for timber floors?
Both Fortis Coat 519 and Fortis Coat 526 can be used on correctly prepared timber. Coat 519 is single-pack, while Coat 526 offers a low-odour water-based alternative.
Which polyurethane coating is suitable for garage floors?
Coat 519 may be suitable for prepared concrete garage floors, while Coat 527 is an option for compatible epoxy and decorative flake systems. Consider tyre contact, traffic, chemical exposure and the complete coating system before selecting a product.
Are polyurethane coatings resistant to tyre staining?
Tyre staining resistance varies with the coating, tyre composition and service conditions. Fortis Coat 519 lists tyre stain resistance subject to Fortis Technical Note #8. For critical automotive applications, confirm the required performance with Fortis.
What is hot tyre pick-up?
Hot tyre pick-up occurs when a floor coating loses adhesion or lifts under hot vehicle tyres. It differs from tyre staining, which causes discolouration. Correct substrate preparation, adhesion and curing are essential for resistance.
Does Fortis Coat 526 require a separate primer?
Fortis Coat 526 is self-priming on suitable prepared substrates. Use Coat 526 Gloss for the first and build coats, followed by Gloss or Satin for the final finish.
When should I use Fortis PAP?
Fortis PAP is an adhesion promoter for difficult, high-quartz and siliceous concrete where additional adhesion is required before a compatible polyurethane coating. It does not replace mechanical surface preparation.
Are Fortis polyurethane coatings UV resistant?
Fortis Coat 519, 526 and 527 provide UV-resistant clear finishes. Product selection should also consider the substrate, exposure conditions and required durability.
Can polyurethane coatings be used in factories and warehouses?
Yes, where the selected coating system is suitable for the expected loading and exposure. Fortis Coat 527 is intended for more demanding commercial applications. Confirm forklift traffic, chemical exposure and cleaning requirements before specifying.
