FORTIS COAT 526 is a premium, self-priming two-component water-based clear polyurethane coating designed to protect and enhance concrete, timber and compatible prepared surfaces.
The self-priming system simplifies application by using Coat 526 Gloss as the first and build coats, eliminating the need for a separate primer on suitably prepared substrates. Additional Gloss coats can be applied to achieve the required film build before application of the final finish.
With an ultra-low VOC content of less than 10 g/L and low odour during application, Coat 526 is particularly suited to residential, commercial and occupied environments where reduced solvent exposure is important.
Once cured, Coat 526 provides excellent wear and abrasion resistance with a clear, UV-stable finish that maintains and enhances the appearance of the underlying surface. Typical applications include concrete floors, timber floors, decorative concrete, benchtops, stairs, walls and other compatible interior or exterior surfaces.
For a Gloss finish, Coat 526 Gloss is used for both the build coats and final coat. For a Satin finish, Coat 526 Gloss is used for the build coats, followed by Coat 526 Satin as the final coat.
Two-component water-based polyurethane
Preparation: Ensure the substrate is correctly prepared, clean, dry and free from dust, oil, grease and contaminants that may affect adhesion.
Mixing: Combine Part A and Part B at 4.5:1 by volume. Mix thoroughly using a low-speed mechanical mixer while minimising air entrainment. Mix only enough material for use within the working time.
First Coat: Coat 526 is self-priming on suitable prepared substrates. Apply Coat 526 Gloss as the first coat, ensuring even wetting and coverage.
Application: Apply by brush or roller. For floors, distribute evenly using a 270 mm microfibre roller with approximately 5 mm nap. Maintain an even film and wet edge.
Build Coats: Use Coat 526 Gloss for all build coats. For a Gloss system, use Gloss as the final coat. For a Satin system, apply Coat 526 Satin as the final coat.
Coverage: Approximately 12–15 m²/L per coat, depending on substrate profile and application method.
Working Time: Approximately 45–60 minutes. Typical recoat time is 6–24 hours at 20°C. Apply between 10–35°C. Temperature, humidity and airflow will affect drying and cure.
Suitable Surfaces: Fortis Coat 526 is a self-priming clear polyurethane suitable for correctly prepared concrete, timber and other compatible substrates.
Concrete: Concrete must be sound, clean and free from laitance, curing compounds, oil, grease, dust and other contaminants that may interfere with adhesion. Diamond grinding is the preferred preparation method for most concrete floor applications.
Apply Coat 526 Gloss directly to suitable prepared concrete as the first coat. Porous concrete may absorb additional material and require further Gloss coats to achieve uniform sealing and film build.
Timber: Timber should be clean, dry and thoroughly sanded to provide a uniform surface. Remove all sanding dust and contamination before applying Coat 526 Gloss as the first coat.
Existing Coatings: Existing coatings must be firmly bonded, clean and mechanically abraded to provide a suitable key. Compatibility and adhesion should be confirmed on a representative test area before proceeding.
For unusual or difficult substrates, contact Fortis for substrate-specific preparation advice before application.

Fortis Coat 526 is a self-priming clear water-based polyurethane used to protect concrete, timber and compatible prepared surfaces. Typical applications include floors, stairs, benchtops, walls and decorative concrete.
Coat 526 is self-priming on suitable prepared substrates. Coat 526 Gloss is applied as the first coat and is also used for subsequent build coats.
Coat 526 Gloss is used for the first and build coats to achieve the required sealing and film build. The final coat then determines whether the finished surface is Gloss or Satin.
Apply Coat 526 Gloss as the first and build coats, then apply Coat 526 Satin as the final coat to achieve an even Satin finish.
Coat 526 is a two-component, self-priming water-based polyurethane with ultra-low VOC and low odour. Coat 519 is a single-pack clear polyurethane designed for durable, non-yellowing protection of compatible prepared surfaces.
Yes. Coat 526 Gloss can be applied as the first coat to suitable correctly prepared concrete. Diamond grinding is recommended for most concrete floor applications.
Yes. Coat 526 can be applied to correctly prepared timber. The timber should be clean, dry and thoroughly sanded before applying Coat 526 Gloss as the first coat.
Typical coverage is approximately 12–15 m²/L per coat. Actual coverage varies with substrate porosity, surface profile and application method.
