How long does it take to varnish a staircase?

Time It Takes to Varnish a Staircase


The question of how much time is needed to varnish a staircase is crucial for our clients in Montreal, Laval, Longueuil, and the South Shore and North Shore regions. At Plancher Deluxe, we understand that varnishing is a critical step in maintaining your staircase, and we are dedicated to providing a service that is both efficient and of high quality.

Preliminary Steps

Preparing the Staircase

  • Cleaning: Ensure the staircase is completely clean and free of dust.
  • Sanding: Floor sanding is an indispensable process to prepare the surface. It helps to remove imperfections and ensures better adhesion of the varnish.

Choosing the Varnish

  • Type of Varnish: Depending on the usage and exposure of the staircase, choose a suitable varnish – water-based, polyurethane, or oil-based.
  • Color and Finish: Consider the aesthetic aspect in relation to your home’s interior.

Applying the Varnish

First Coat

  • Application: Apply the first coat evenly.
  • Drying: Allow it to dry completely, which can take from 4 to 6 hours, depending on the type of varnish.

Additional Coats

  • Light Sanding Between Coats: For better adhesion, light sanding is recommended between each coat.
  • Number of Coats: Generally, two to three coats are necessary for a durable and quality finish.

Factors Influencing Varnishing Time

  • Humidity and Temperature: Climatic conditions like high humidity or low temperatures can prolong drying time.
  • Ventilation: Good ventilation is crucial for faster drying.

Total Duration of the Process

On average, the complete varnishing process of a staircase can take from 1 to 2 days. This includes preparation, the application of different coats, and drying time between each step.

Post-Varnish Maintenance

  • Normal Use: Wait at least 24 hours before resuming normal use of the staircase.
  • Long-Term Maintenance: Regular maintenance with suitable products can extend the life of the varnish.


At Plancher Deluxe, we commit to offering a staircase varnishing service that is quick, efficient, and of high quality. We take into account every detail to ensure a perfect finish, tailored to the needs and style of each client in the Montreal area and its surroundings.
