Is it possible to varnish a wood floor without sanding?

Innovation in Floor Varnishing

In the field of floor renovation in Montreal, Laval, Longueuil, as well as the South Shore and North Shore, a common question arises: is it possible to varnish a wood floor without going through the floor sanding stage? At Plancher Deluxe, we are constantly seeking innovative techniques to meet our clients' needs.

Understanding the Traditional Process

The Role of Sanding

  • Surface Preparation: Floor sanding, or sablage de plancher, is essential to prepare the wood surface by removing old varnish layers, dirt, and imperfections.
  • Optimal Adhesion: This step ensures better adhesion for the new varnish.

Limitations of Sanding

  • Time and Effort: Sanding is a time-consuming process that requires specific equipment.
  • Dust: It can generate a lot of dust, despite modern dust capture technologies.

Varnishing Without Sanding: Reality or Fiction?

Alternative Techniques

  • Thorough Cleaning: Sometimes, meticulous cleaning may suffice to prepare the surface for a new varnish.
  • Specific Products: There are varnishes designed to adhere to unsanded surfaces.

Factors to Consider

  • Floor Condition: This technique is more suitable for floors in good condition, without major damage.
  • Durability: Varnishing without sanding may offer less durability compared to the traditional method.

Advantages and Disadvantages


  • Speed: Significant time savings.
  • Environment: Less dust and waste produced.
  • Practicality: Ideal for occupied spaces or tight schedules.


  • Less Durability: Potentially less resistant to scratches and wear.
  • Limited to Certain Floor Types: Not suitable for very damaged floors or those with thick, old varnish layers.
