How to Refinish Parquet Flooring Properly

Parquet can look tired long before it is beyond saving. A dull finish, light scratches, old varnish and patchy colour often make homeowners think replacement is the only option, when in many cases the better answer is learning how to refinish parquet flooring properly and understanding where a careful restoration makes all the difference.

Why parquet needs a different approach

Parquet is not the same as sanding standard floorboards. Whether you have herringbone, chevron or block parquet, the pattern itself is part of the value of the floor, and that means the refinishing process has to protect both the timber and the layout. Sand too aggressively, use the wrong grit sequence or rush repairs, and you can end up softening edges, exposing gaps or creating an uneven appearance across the pattern.

This matters even more in London homes, where parquet is often found in period properties, conversions and well-used family rooms. Many floors have already been sanded before, and some have had years of polish, wax, carpet adhesive or DIY touch-ups applied over the top. A good result depends on reading the floor first, not just hiring a machine and starting.

How to refinish parquet flooring step by step

The refinishing process usually starts with inspection. Before any sanding takes place, you need to know what the blocks are made from, whether they are solid wood or engineered parquet, how much wear layer remains and whether any pieces are loose. If blocks are lifting, cracked or water-damaged, those repairs should be dealt with before the main sanding begins.

The room then needs to be fully cleared. Furniture, rugs and door thresholds all need to come out, and skirting edges may need protection depending on the finish and sanding equipment being used. Professional sanding teams use dust-controlled systems with high-grade extraction, which makes a major difference in occupied homes. That is particularly useful in London flats and terraced houses where disruption needs to stay manageable.

1. Repairs come first

A parquet floor should be stable before it is refinished. Loose blocks may need to be re-bonded, missing pieces replaced with matching timber and old bitumen or adhesive issues assessed properly. Gap filling can also help, but it depends on the age and movement of the floor. Very fine gaps can often be filled during sanding, while wider or active gaps may need more selective repair work.

This is one of the main points where DIY projects start to struggle. On parquet, a repair that is slightly proud, slightly uneven or poorly aligned stands out quickly because the pattern draws the eye.

2. Sanding removes the old finish

Once repairs are complete, the old lacquer, wax or surface damage is sanded away in stages. This is not a one-pass job. Parquet usually needs a careful grit progression to flatten the surface without tearing at the grain or leaving heavy scratch marks. Edges and corners are then sanded separately so the finish remains consistent across the room.

Older parquet often has small height differences between blocks, especially if previous repairs have been carried out. Sanding evens this out, but only within reason. If the floor has severe movement or substantial historic damage, refinishing can improve it dramatically, though it may not make every block look newly installed.

3. Filling and fine preparation

After the main sanding passes, the floor is checked again for small gaps, pinholes and surface imperfections. Resin filler mixed with fine sanding dust is commonly used to create a closer colour match. Once dry, the floor is lightly sanded again to leave it smooth and ready for finishing.

This stage affects the final appearance more than many people expect. A good finish sits on preparation. If sanding marks, rough edging or poor filling are left behind, the sealant will highlight them rather than hide them.

Choosing the right finish for parquet

The finish changes both the look and the day-to-day maintenance of the floor. Most homeowners choose between lacquer and hardwax oil, and each has strengths.

Lacquer gives a durable sealed surface and is popular for busy family homes, rentals and high-traffic areas such as hallways. It comes in matt, satin and extra matt options, so you do not have to accept a shiny look unless you want one. It is generally easier to keep clean and can be a strong choice where practicality matters most.

Hardwax oil gives a more natural, low-sheen appearance that many people prefer in period interiors and decorative parquet rooms. It tends to enhance the grain and warmth of the timber beautifully, but it does need the right maintenance products and a little more care over time.

If you are also thinking about staining the floor, parquet needs extra attention. Because the grain direction changes across the pattern, stain can take differently from block to block. That can look striking when done well, but patchy if the preparation is poor or the timber has mixed history. Sample testing is always worth doing before committing to a full room.

Can you refinish parquet flooring yourself?

Technically, yes. In practice, it depends on the floor, your expectations and your tolerance for risk.

If the parquet is modern, flat, lightly worn and in a spare room, a confident DIY approach may be possible. But many parquet floors in London homes are older, more delicate and less forgiving than they first appear. Machine choice, sanding pressure, edging technique and product application all affect the final result.

The biggest risks are over-sanding, visible drum marks, poor repairs and choosing a finish that does not suit the room. There is also the issue of dust and disruption. Professional teams use commercial machinery from brands such as Bona, Lagler and Festool with proper extraction systems, which makes the process cleaner, faster and more controlled.

For homeowners who want a floor to add value, improve presentation before sale or restore original character, specialist sanding is usually the safer investment.

How long does parquet refinishing take?

A single room can often be sanded and finished within one to three days, but timing depends on the size of the area, the condition of the parquet and the finish being applied. Repairs, staining and drying times all add to the programme.

Drying and curing are not the same thing. A floor may feel dry to the touch within hours, yet still need more time before heavy furniture goes back in place or rugs are laid down. Rushing that stage can mark the new finish before it has had a chance to harden properly.

In lived-in homes, the practical question is usually not just how long the work takes, but how long the room is out of action. Planning this properly helps avoid frustration.

What does it cost to refinish parquet flooring?

Costs vary according to floor condition, access, room size and the level of repair needed. A clean, straightforward sand and seal is naturally less expensive than a full restoration with block replacement, staining and multiple finish coats.

Parquet can cost more to refinish than plain floorboards because of the extra detail involved. Repairs are often more precise, edging takes care, and the visual standard is higher because the pattern is such a strong design feature. That said, refinishing is usually far more cost-effective than lifting the floor and starting again.

A proper quote should take account of sanding, repairs, filling, finishing products and expected drying times, rather than giving a one-price-fits-all figure over the phone.

When refinishing is not the right answer

Not every floor should be sanded again. If the parquet is engineered with too little wear layer left, heavily water-damaged, badly delaminated or unstable across large areas, replacement or partial renewal may be the better route. The same applies where blocks have failed because of subfloor problems that need solving underneath.

This is where an honest assessment matters. A trustworthy specialist will tell you when a floor is a good candidate for refinishing and when the money is better spent on repair or replacement work instead.

Getting the best result in a London home

In London properties, access, noise control, dust management and timing all matter alongside the finish itself. A beautiful parquet restoration is not just about the final coat. It is about careful preparation, the right equipment and a team that understands both old timber and modern living.

At Love Your Floor London, that usually means balancing craftsmanship with low-disruption working methods, especially in occupied homes where clients want a cleaner process and a finish that lasts. Whether the parquet sits in a Victorian terrace, a mansion block flat or a newer family home, the principle is the same: restore what is worth keeping, and do it properly.

If your parquet still has sound timber beneath the wear, refinishing can bring back character, depth and value in a way replacement rarely matches. The best place to start is not with a sander, but with a clear view of what the floor needs.
