What Is Parquet Flooring?

Parquet flooring refers to hardwood flooring constructed from small planks positioned to form geometric patterns. Standard straight planks differ from these small blocks or strips of wood that arrange into decorative layouts like herringbone, chevron, basketweave, and chequerboard. The term originates from the French 'parchet', meaning 'small enclosed space', famously popularised in 17th-century France at the Palace of Versailles.

Parquet comes in two main forms. Traditional solid parquet blocks are 15-22mm thick and can withstand multiple sanding cycles throughout their lifetime. Engineered parquet features a thin veneer layer over a plywood or composite base, with the veneer thickness determining how much sanding the floor can tolerate. Wood types vary and include oak, teak, beech, pitch pine, sapele, and merbau.

Why Parquet Flooring Fades and Gets Damaged

Parquet flooring deteriorates for several reasons. Water damage ranks as one of the biggest problems, with moisture penetrating seals and causing warping, discolouration, and increased scope for bacterial growth. Excessive water from leaks, flooding, or overzealous mopping deforms the wood and blocks lift up.

UV light causes oxidation, a natural effect where wood exposed to light and air changes colour depending on exposure intensity. All types of wooden floors darken over time due to UV light. Wood covered by furniture and carpets will appear darker than wood exposed to light and air.

Temperature and humidity fluctuations create additional problems. Parquet is sensitive to changes in temperature and humidity, which can cause the flooring to warp, shrink, and lift up. Natural expansion and contraction due to modern central heating guide to gaps between blocks. Heavy use reduces gloss and causes dents or scratches. The protective surface wears away in high-traffic areas, exposing the wood underneath to dirt, moisture, and sunlight.

Signs Your Parquet Floor Needs Restoration

Visible scratches, scuffs, or dull patches in busier spaces signal surface wear. Faded or uneven colour, especially in sunlight-exposed areas, indicates a deteriorated finish. Loose blocks create slight movement or hollow sounds when walking. Gaps between blocks collect dirt or moisture. Water damage demonstrates as stains or discolouration on the surface. Sanding becomes necessary if cleaning or polishing fails to revive the floor's appearance. Rough, splintered, or uneven surfaces suggest the finish has worn away.

Assessing the Damage and Preparing for Restoration

Inspecting Your Parquet Floor for Problem Areas

Professional assessment is the foundation of successful restoration. Surveyors get into wood moisture content and identify structural issues. They check for woodworm or rot. Walk across the entire floor area. Pay attention to high-traffic zones and areas near windows where UV damage occurs. Spots around radiators where heat may have caused shrinkage or warping need checking too.

Test for loose blocks by tapping or pressing gently. Hollow sounds indicate subfloor or adhesive problems. Water damage presents unique challenges. Black staining indicates deep moisture penetration that may have weakened the wood structure. Check for squeaks, bouncing, or movement when walking. These suggest subfloor problems that need addressing before restoration begins.

Record and monitor any changes after storms, spills, or renovation works. Photograph suspicious patches. The details will help if you seek professional assistance later.

Gathering Tools and Materials You'll Need

Restoration just needs specialist equipment unavailable through standard contractors. Parquet floors have boards that point in different directions, making them quite tricky to sand. Specialist equipment is used on parquet floors. Other tools may cause more damage than they fix.

Professional restoration uses multi-disc sanders or belt sanders with specific grit sequences designed for parquet work. Heavy-duty dust extractors keep the site and air clean. You'll need compatible adhesives for re-bonding loose blocks and colour-matched fillers for gaps. Floor-specific finishes are also required. Generic adhesives can react unpredictably with historic glues. Off-the-shelf fillers can shrink or stain blocks over time.

Deciding Between DIY and Professional Restoration

The size of the job guides whether a contractor is needed. You may be able to do this yourself for very small areas of floor such as in small bathrooms or hallways. Think over replacement when more than 20% of blocks are loose, missing, or damaged badly.

Parquet restoration requires expertise that's unavailable through standard flooring contractors. Seek specialists with experience restoring period properties. They showed their skills and have appropriate insurance coverage.

How to Fix Damaged Parquet Flooring

Repairing damaged parquet requires different approaches depending on the issue type.

How to Fix Loose Parquet Flooring

Lift loose blocks using a chisel without damaging neighbouring pieces. Clean old adhesive from both the block and subfloor. Use solvent-based adhesive rather than water-based options, as it bonds better with old bitumen. Press blocks back into place and weight them down for 12-24 hours whilst the adhesive cures.

How to Fix Scratches on Parquet Flooring

Mix equal parts olive oil and vinegar for superficial scratches, rub into the scratch, then buff the surface. Minor scratches respond well to wax sticks or wood touch-up markers matched to your floor colour. Deep scratches require wood filler applied with a putty knife. Sand smooth once dry, then stain and finish to match surrounding areas.

How to Fix Dents in Parquet Flooring

Place a dampened towel over the dent and apply a hot iron for 3-5 minutes. The moisture and heat cause wood fibres to swell back to their original level. Use colour-matched wood filler or a wax repair kit with a melting knife to fill deeper dents.

How to Fix Water Damaged Parquet Flooring

Remove visible water using towels or a wet vacuum right away. Use fans and dehumidifiers to dry the floor. Measure moisture content with a hygrometer; once it reaches maximum 9%, sanding can commence. Replace warped or rotted boards rather than attempting repairs.

Filling Gaps and Cracks in Parquet

Mix fine sawdust from sanding with resin fillers or cellulose hardener to create a paste. Trowel the mixture into gaps and clean excess off the surface, then lightly sand once dry. Gap filling improves appearance and extends floor finish life.

Replacing Missing or Damaged Blocks

Source reclaimed blocks matching the original wood species, size and thickness. Clean the subfloor area, apply suitable adhesive, and press the replacement block into position following the existing pattern. Sand and finish to blend with surrounding flooring.

Sanding, Refinishing, and Restoring the Finish

When Sanding Is Necessary

Sanding parquet every 7-10 years prevents wear buildup. Not every floor needs full sanding to bare timber. You can often refinish without sanding to raw timber if your surface wear is moderate, the wood underneath is sound, and the topcoat is worn rather than failed (peeling, flaking, or scratched through to wood). 

Choose screen and recoat if you like the current colour, have surface wear, and the old finish remains intact. Choose full sanding if there are deep scratches, grey water staining, cupping, heavy pet damage, widespread peeling, or you want a new colour.

Proper Sanding Techniques for Parquet Patterns

Parquet demands sanding at a 45-degree angle to the grain, which lines up with the pattern's direction. Start with coarse grit (40), then medium grit (60), and finish with fine grit (120). Multiple passes at slight angles work towards the final finish and cut down cross-grain scratching. Rushing this process often causes permanent damage.

Choosing and Applying the Right Finish

Water-based products like Bona Traffic and Junckers HT700 provide durability with low odour and quick drying. Oil-based products provide recoating flexibility but need longer drying times. Apply finishes evenly in the direction of the grain to improve the pattern and avoid streaks.

Restoring Faded Parquet Without Sanding

Screen and recoat uses a floor buffer with abrasive mesh to scuff the finish, then applies a new topcoat. This method produces less mess and downtime while preserving material for future sanding life.

You now have all the knowledge needed to restore your faded or damaged parquet flooring back to its former glory. Whether you're tackling scratches or water damage, these techniques will help you make the right decisions.

Most parquet floors respond well to proper restoration. Start by assessing your damage honestly and gather the right materials. Don't hesitate to call professionals to handle larger projects. Your beautiful parquet floor will thank you.
