How to Choose the Right Grit for Floor Sanding?
The Importance of Grit Selection in Floor Sanding
Floor sanding is a crucial step in renovating and maintaining wooden floors. The choice of sandpaper grit plays a key role in achieving a perfect finish. At Plancher Deluxe, experts in floor sanding in Montreal, Laval, Longueuil, South Shore, and North Shore, we understand the significance of this choice and aim to guide you through this process.
Identifying the Wood Type and the Floor's Condition
Before selecting the grit, it's essential to assess the type of wood and the current condition of the floor. Hardwoods like oak and maple require finer grits, while softer woods like pine can be worked with coarser grits.
The Sanding Sequence
Sanding is generally done in three stages:
- Coarse Sanding: Using coarser grits (30-60) to remove old finishes and major flaws.
- Medium Sanding: Switching to a medium grit (80-120) to smooth the surface.
- Fine Finishing: Fine grit (150-220) for a smooth finish ready for varnishing.
Practical Tips for Choosing the Grit
- Assess the wear: For heavily worn floors, start with a coarser grit.
- Beware of scratches: A too coarse grit on soft wood can cause hard-to-remove scratches.
- Test on a small area: Before proceeding with the entire floor, do a test on a small section.
Sanding Stairs and Railings
Sanding stairs and stair railings requires special attention. Use a medium to fine grit to avoid damaging the wood.
Sanding Decks and Antique Floors
For decks exposed to the elements, a medium grit is often sufficient. For antique floors, a fine grit is preferable to preserve the details and patina of the wood.
Commercial Sanding Services
For commercial projects, where durability and speed are essential, we recommend professional sanding with grits suited to the traffic demands.
