The yield of glazes varies depending on the product and its application, but here is a general estimate:

Average yield of glazes:

• Per coat: Between 8 and 12 m² per litre.
• For two coats (without a hard base): Approximately 4 to 6 m² per litre.
• For three coats (on raw wood): Approximately 3 to 4 m² per litre.

Factors influencing yield:

1. Type of sealer:
   • Water-based or polyurethane sealers generally offer a yield of 10 m²/litre per coat.
   • Some specific products, such as two-component sealers, may cover slightly less due to their viscosity.
2. Condition of the substrate:
   • Raw or very porous wood will consume more product.
   • Applying a hard primer beforehand reduces the quantity needed for subsequent coats.
3. Number of coats:
   • Two coats are often sufficient on a wooden floor that has been prepared beforehand with a hard primer.
   • Three coats are recommended for optimal protection on raw wood.

Practical examples:

• With a 1 litre pot, you can cover approximately:
  • 10 m² with a single coat.
  • 4 to 5 m² with two coats.
• A 2.5 litre pot will cover approximately:
  • 25 m² with a single coat.
  • 10 to 12.5 m² with two coats.

Tips for optimising use:

• Apply a hard primer before sealing to reduce consumption.
• Use a microfibre roller or synthetic bristle spalter for even application.
• Allow for drying time between coats and sand lightly between coats for a better finish.

In short, the yield depends on the product chosen, the surface and the conditions of application. Always check the manufacturer's specific recommendations to ensure optimal results.
