The steps involved in floor sanding and varnishing in Quebec!
Sanding a floor is best done when all the preparatory work has been done and the surface has been cleared for the contractor. Under these conditions, the work can be completed quickly, so it’s best to follow the steps in order when sanding and varnishing your floor.
Here are the main stages of floor sanding and varnishing in Quebec!
1) Seal the room and close ventilation
Even if you opt for dust-free sandblasting, there’s still a risk that particles will be released into the air during the work. That’s why it’s a good idea, at the very least, to close off the central ventilation to prevent the spread of dust. In the case of traditional sandblasting (with dust), it’s best to protect the furniture and seal the parts.
2) Remove baseboards and furniture
Baseboards and furniture interfere with the sanding and varnishing process. That’s why they must be removed before the contractor arrives, to avoid delays and expedite the sanding.
3) Floor sanding, varnish removal and dust extraction
Once the rooms have been cleared of clutter, the first step is to remove the varnish or product covering the floor surface. This is done using a specially designed sander.
4) Application of varnish or oil
Once the surface has been sanded and blasted, you’re ready to apply the new finishing product, whether varnish, oil, latex or stain. Be sure to choose a quality product that will last and not damage the wood species.
5) Curing and drying time
The work may be finished, but be careful! You’ll have to wait a while before you can walk on the floor. We’re talking about a cure time of 24 to 48 hours, depending on the type of product applied, before you can walk on the floor and put furniture on it.
And voila, the floor is sanded, varnished and practically as good as new in just a few steps. You’ll have peace of mind for several years before you need to sand and varnish again.

FAQ - Frequently asked questions about floor sanding and varnishing!
How often should a hardwood floor be sanded or varnished?
In general, hardwood floors should be sanded every 10 years. However, this depends on how the floor is used. For example, a home with pets and small children causes more damage to the floor, which may require more frequent sanding and refinishing.

Is it necessary to protect a floor from the sun and UV rays?
Floor varnish is indeed vulnerable to the sun’s rays. And while it’s impossible to stop UV rays, it’s advisable to move furniture and carpets regularly to ensure even wear. A protective film can also be stuck into windows to give the floor a chance, although curtains are effective enough to offer sufficient protection.
Can all wood floors be sanded and varnished?
Hardwood flooring is not the only wood floor covering that can be sanded. Some engineered wood floors can also be sanded if they are thick enough. However, engineered flooring can only be sanded once, whereas hardwood can be restored up to 3-4 times without any problem.
Can floating wood floors be sanded and restored?
No! Floating and laminate floors cannot be restored or sanded. Their “plasticized” finish does not permit such corrective work. When float is scratched, damaged or otherwise worn, it simply has to be replaced. The same applies to vinyl flooring.
