How many coats of sealant should be applied after sanding a wooden floor?

The number of coats depends on the sealant used (solvent-based or water-based) and the hard primer applied beforehand. It is essential to consult the technical data sheet and the manufacturer's recommendations for each product.

As a guide:

• 3 coats are the standard solution to ensure good protection for your floor.
• 2 coats may be sufficient if a suitable undercoat (hard primer) has been applied beforehand.
• In damp rooms or areas subject to heavy use (entrance hall, corridor, kitchen, etc.), 4 coats are recommended for optimum durability.

Practical tips:

• Allow the drying time between each coat (usually 3 to 4 hours).
• Lightly sand between coats to improve adhesion and finish.
• Remember to dust thoroughly after each step.
