Timberlay Engineered Walnut Wood Flooring, 190x4x20 Mm

4 mm Hardwood Wear Layer

Timberlay Engineered Walnut Wood Flooring, Oiled, 190x4x20 Mm has a 4 mm real hardwood top layer, a generous wear layer for engineered wood flooring. The top layer, or wear layer, is the solid wood surface you walk on. Its thickness decides how many times the floor can be sanded and refinished during its life.

A professional sanding usually removes around 0.5–1 mm of timber, so a 4 mm wear layer can typically be renovated 2–3 times. Between sandings, the finish can also be refreshed with a recoat of lacquer or maintenance oil, without sanding back to bare wood.

It offers a great balance of value and longevity, ideal for living rooms, bedrooms and family homes where the floor is expected to last for many years. Compare other 4 mm top layer floors, or browse our full engineered wood flooring range.

Durable Lacquered Finish

A lacquered finish seals the wood beneath a clear, hard-wearing layer, making it one of the most practical choices for a real wood floor. Spills, dirt and moisture stay on the surface instead of soaking into the timber, so they can simply be wiped away before they leave a mark, and the floor stands up well to everyday foot traffic.

Lacquered floors are also among the easiest to look after. There is no regular re-oiling to plan for: sweeping or vacuuming, with an occasional damp mop using a cleaner made for lacquered floors, keeps them looking their best. The smooth, sealed surface doesn't hold on to dust either, making it ideal for kitchens, hallways, busy family homes and allergy sufferers.

Factory-applied lacquers are built up in several coats and cured for extra hardness, giving long-lasting protection in everyday use. Modern water-based lacquers are non-yellowing, so the floor keeps an even colour and sheen for years, with finishes from natural-looking extra matt to classic gloss to suit any interior. It is a finish that keeps your floor looking beautiful while adding lasting value to your home.

Natural Oiled Finish

An oiled finish soaks into the wood and protects it from within, giving the timber a natural, matt look and feel that brings out the warmth and grain of the wood. Floors are often brushed before oiling to emphasise the texture, a finish known as "Brushed & Oiled". Factory-applied UV oils and hardwax oils add extra resistance from day one.

Oil is less hard-wearing than lacquer, but it can be topped up and spot-repaired without sanding the whole floor. Regular maintenance with a compatible oil or hardwax oil can delay a full renovation and preserve the wear layer of your floor.

Traditional oils can take 6–10 hours to dry per coat, so plan re-oiling around a quiet period at home. Putting it off too long can mean an earlier full sanding. Browse all oiled wood flooring.

Walnut Flooring

Walnut is known for its characteristic dark coloured wood with attractive straight and irregular wood grain patterns. Walnut is a dense, heavy and strong wood and therefore is ideal for flooring products.

Although there are many varieties of walnut trees, just a handful are used for flooring. Of them, the Eastern Black Walnut, also called the American Black Walnut or American Walnut, is the one which attracts with its beauty and richness of colour.

Installation

With a 20 mm thickness, Timberlay Engineered Walnut Wood Flooring, Oiled, 190x4x20 Mm gives excellent rigidity and stability, and can even be laid as a suspended floor directly over battens or timber joists (typically at no more than 400 mm centres; always check the manufacturer's guidance). It can be secret-nailed, glued down or floated over underlay, and this thickness often comes with an extended guarantee.

Over underfloor heating (UFH) a glue-down installation is highly recommended, using a flexible wood flooring adhesive from our adhesives & damp-proofers range.

A thicker board usually also means a deeper wear layer above the tongue, so the floor can be sanded and refinished more times over its life. Explore our 20 mm flooring collection.

Maintenance

Lacquered wood floors are easy to look after. Vacuum with a hard-floor head or sweep regularly to remove grit, which can scratch the surface. Every so often, clean with a pH-neutral, lacquer-friendly cleaner that leaves no moisture or residue. For everyday cleaning we recommend the Bona Spray Mop with Bona Cleaner refills, available in our cleaning & maintenance range.

Avoid steam cleaners, wet mops, wax or oil-based polishes, which can damage the finish or make it slippery. Wipe up spills promptly, fit felt pads under furniture and use doormats at entrances to keep the floor looking new for longer.

When a busy area starts to look dull or worn, and the lacquer hasn't worn through to bare wood, it can be lightly abraded and given a fresh coat of floor lacquer without a full sanding.

Maintenance of Oiled Floors

Oiled floors bring a warm, natural feel to any room, but they need a little more regular care than lacquered floors. Sweep or vacuum regularly, then clean with a soap-based cleaner made for oiled floors, which nourishes the wood as it cleans. We recommend the Bona Spray Mop for Oiled Floors, available in our cleaning & maintenance range.

Depending on foot traffic, top up the finish with a maintenance oil typically every 1–2 years, and more often in busy areas such as hallways and kitchens. Regular re-oiling keeps the wood protected and can put off a full sanding, which preserves the wear layer of your floor.

A big advantage of an oiled finish is that light scratches and worn patches can be spot-repaired without treating the whole floor. Find compatible products in our oil & hardwax-oil range.
