Whether your floor is pine, parquet, engineered wood, mosaic finger parquet, or solid hardwood, we’ve got you covered. Additionally, we explore finishing options to suit different styles and wood types, ensuring you achieve the look you desire.
Why Floor Sanding is the Key to Wood Floor Restoration
Floor sanding is the process of stripping away the top layer of wood, including any existing finish, imperfections, and minor damage, to reveal a smooth, fresh surface. Once sanded, the wood is treated with a protective finish that enhances its durability, colour, and texture.
Key benefits of floor sanding include:
- Aesthetic Improvement: Restores the original beauty of the wood, highlighting its natural grain and patterns.
- Increased Durability: Allows for the application of protective finishes that resist scratches and stains.
- Cost-Effectiveness: Extends the lifespan of your flooring, saving you the expense of replacement.
- Versatility: Enables you to change the finish, stain, or colour to align with modern trends or personal preferences.
The Floor Sanding Process
The process of floor sanding involves several steps to ensure a flawless and professional result.
Initial Inspection and Preparation
Before sanding, the chosen professional will inspect the flooring for damages, loose boards, or uneven surfaces. Preparation involves:
- Clearing the Room: All furniture, rugs, and objects needs to be removed to allow free access to the entire floor. This is usually mandatory, in order to achieve smooth and uniform finish throughout.
- Repairs: Loose boards & blocks are secured, damaged pieces are replaced, and nails or screws are countersunk to prevent machine damage.
Repairs and Gap Filling
- Replacing Damaged Planks: Severely damaged boards are replaced with matching size wood. In many cases the flooring material for the repair work is obtained from reclaimed source, in order to maintain consistency.
- Missing Sections: In many properties, missing section of the flooring has been previously repaired with concrete, plywood or inappropriate timber. The most often repair required is around fireplace that is no longer there. In order to properly repair this, it usually requires portion of the existing flooring to be removed and extended. Furthermore, by creating a stagger joint or continuing the original pattern will make the repair work unnoticeable.
- Gap Filling: Gap filling is very standard method of filling any gaps, cracks and deep dents that you may have on your wooden flooring. Depending on the type of the gaps, the actual gap filling method, may vary.
- Wood Fillers: Pre-mixed fillers are used to fill small gaps and cracks. This wood fillers can come in different colours, depending on the wood flooring specie. As those are ready made, there is likely to be some colour/shade difference between the filler and the actual flooring. For this reason, this method is mainly used for DIY jobs, rather than by floor sanding professionals.
-
- Wood Slivers: Natural wood slivers are inserted into larger gaps. Most commonly, pine slivers are fitted to cover the large gaps between the boards. This will ensure smooth appearance of the flooring. Moreover, it can also minimise the draught from underneath. This method is usually suitable for gap filling of larger, open gaps of over 3mm.
-
- Mix of Resin & Sawdust: The most common way of gap filling any small gaps, cracks and nail holes is mix of resin and sawdust. During the sanding process, fine sawdust is collected from the very same flooring. The sawdust is then mixed with resin. This mix is applied in the gaps and cracks of the flooring. Once dry it will provide as close as possible colour to the existing floor.
Floor Sanding
Floor Sanding is the cornerstone of any wooden floor restoration project, as it transforms worn and uneven surfaces into a smooth and flawless foundation ready for finishing. Using industrial-grade machines and a multi-stage approach, sanding removes imperfections, restores the wood’s natural texture, and ensures an even, professional result.
Stages of the Floor Sanding Process
- Coarse Sanding:
- The first stage uses coarse grit sandpaper to strip away old finishes, varnishes, or stains and to level uneven surfaces.
- This step is crucial for removing deep scratches, dents, and ingrained dirt that cannot be eliminated by finer sanding.
- Medium Sanding:
- This intermediate step smoothens the wood surface and addresses any scratches or roughness left behind by the coarse sanding stage.
- It refines the floor’s texture and begins to reveal the wood’s natural grain.
- Fine Sanding:
- The final stage uses very fine grit sandpaper, or sand screen to create a silky-smooth surface, perfect for applying finishes.
- This step ensures the floor is free from minor imperfections, preparing it to absorb finishes evenly and achieve a flawless appearance.
The finish you choose determines both the appearance and durability of your flooring. Below is a guide to popular finishes:
- Oils:
- Penetrate deeply into the wood, offering a matte, natural look.
- Available in clear, tinted, or UV-cured varieties for added versatility.
- Best for high-traffic areas and homes seeking a modern aesthetic.
- Lacquers:
- Form a hard, protective layer on the surface, available in matte, satin, or gloss finishes.
- Ideal for homes with children or pets due to their scratch resistance.
- Waxes:
- Traditional finish that adds a warm, low-sheen look but requires regular maintenance.
- Suitable for solid wood and pine floors.
- Stains:
- Transform the wood’s colour while retaining its natural grain.
- Available in a wide range of shades, including grey, white, and rich brown tones.
- Water-Based Finishes:
- Eco-friendly and low in VOCs, making them a healthier choice for London homeowners.
- Dries quickly, allowing for faster project completion.
Floor Finish Drying Times & Application
Depending on the chosen type of finish, the application, as well as the drying time will vary.
In general lacquer is fast drying floor finish that will allow for the flooring area to be accessible in approximately 4-5 hours after the application of the final coat. Homeowner/s, who would like to remain in the property during the floor sanding work, often prefer this type of finish. This will ensure that the occupants will have access as soon as the work is complete.
Hard Wax Oil finishes on the other hand requires more time 12-24 hours drying time for each coat. For people that would like to stay in the property during the flooring renovation, finishing the wooden floor with hard wax oil finish, could be challenging.
To carry out intermediate buffing, or fine polishing between the coats is standard practice for all floor sanding professionals. This is a necessary step in order to achieve as smooth finish, as possible.
Can All Imperfections of the Flooring Be Rectified with Floor Sanding?
Floor sanding is an excellent way to breathe new life into your wooden flooring. It can restore its natural beauty, bringing back the elegance and character it had when first installed. However, as floor sanding is primarily a surface treatment, it has certain limitations. While it effectively removes surface imperfections, some deeper or more intrinsic flaws may remain visible or require additional intervention.
What Can Be Rectified with Floor Sanding
Floor sanding can address many common issues, including:
- Marks of Wear and Tear: Surface-level scuffs and damage caused by foot traffic can be easily sanded away.
- Surface Scratches and Dents: Light scratches and shallow dents are smoothed out during the sanding process.
- Discoloration: Fading or uneven coloration caused by sunlight or old finishes can be restored to an even tone.
- Large Gaps Between Wood Blocks or Planks: These can often be repaired during the sanding process with appropriate gap-filling techniques, such as using wood fillers or slivers.
Marks That May Not Be Fully Removed, but Can Be Disguised
Some deeper imperfections may not be completely erased. However, it may be possible for those to blend in, by carrying additional treatments:
- Deep Stains and Marks: Stains from spills, such as water or oil, that have penetrated too deeply into the wood grain may not be entirely removable. However, sanding can lighten these stains, and applying a dark or tinted finish can help to disguise them.
- Deep Scratches and Dents: While sanding may reduce their appearance, additional measures like gap filling or wood repairs may be needed to address deeper damage.
- Imperfections from Previous Floor Coverings: Previous marks that have had deep impact onto the wooden flooring, such as paint splashes, adhesive marks, or indentations from carpet underlay may persist. However a carefully chosen finish or stain, can disguise them, so they would not be as obvious.
What Is Likely to Remain After Floor Sanding
Some imperfections are inherent to the wood or its history and may remain visible even after sanding:
- Colour/Shade Differences Between Blocks/Boards: Natural variations in wood colour, or differences between newer and older sections of the floor may be highlighted rather than hidden after sanding. It often happens if previous repair is done using timber from different wood specie, as well as age or origin.
- Insect Marks and Worm Holes: These are often seen in older floors and may remain as part of the wood’s character. Some homeowners choose to preserve these as features of aged wood, rather than replacing the affected boards/blocks.
- Old Filler: Pre-existing fillers that are incompatible with the new finish may still be visible unless removed and replaced during the restoration process. In many cases the old filler will require extensive labour and it is time consuming (and often costly) option.
- Creaky Boards: Cause of this could often be related to issues with the subfloor rather than the wood surface itself. While sanding improves the floor’s appearance, creaking may persist and require appropriate repairs.
How to Handle Persistent Imperfections
For homeowners looking to achieve the most flawless result, additional solutions can complement the sanding process:
- Stains and Finishes: Opt for tinted stains or coloured finishes to unify the appearance of the floor and disguise stubborn imperfections, as well as some colour/shade difference between the different boards.
- Deep Repairs: Replace severely damaged planks, blocks, or sections of flooring.
- Professional Gap Filling: Use resin-based fillers, natural wood slivers to handle wide or irregular gaps.
- Structural Repairs: Address subfloor issues causing creaks or movement before sanding begins.
By understanding the possibilities and limitations of floor sanding, you can set realistic expectations and achieve a beautifully restored floor with the help of skilled professionals.
How often shall you do floor sanding?
A standard assumption is that carrying floor sanding and renovation once every 10-12 years is perfectly fine.
