How to Deal with Gaps and Warping in Reclaimed Floorboards
Reclaimed floorboards bring character, texture, and history into a space. They also behave differently from new timber. Gaps and warping are common issues. They are
Reclaimed wood flooring brings timeless character, rich patina, and organic warmth to any space – but like all real timber, it needs the right protective finish to perform well over time. The coating you choose affects not only durability and maintenance, but also colour, sheen, and the way natural grain features are showcased.
At Reclaimed Wood Flooring UK, we know that the right finish can enhance both performance and beauty. In this guide we’ll walk you through the most common and effective protective coatings for reclaimed wood flooring, how they work, and how to choose the best option for your home.
Hardwax oil has become one of the most popular finishes for reclaimed wood – and for good reason. Rather than forming a solid film on the surface, hardwax oils penetrate the wood fibres and create a durable, breathable layer that protects against spills, abrasion, and daily wear.
Hardwax oil offers a more natural look and feel than thick surface coatings. It enhances the wood’s grain and patina without creating a plastic-like surface. Because it’s breathable, the wood still responds to changes in humidity, which is important for older, seasoned reclaimed boards.
Benefits:
Natural, low-sheen finish that highlights texture
Easy to repair small marks without full refinishing
Improved slip resistance
Ideal for high-traffic living spaces
Considerations:
Requires occasional maintenance (re-oiling) depending on use
Not as “sealed” as some film finishes (but easier to repair)
For many homeowners, hardwax oil strikes the perfect balance between performance and aesthetic warmth.
Traditional oil finishes (such as tung, Danish, or linseed oil) have been used for centuries to bring out the depth and richness of wood. These oils soak into the timber, enriching colour and giving reclaimed boards a softer, hand-rubbed look.
Unlike harder, film-forming finishes, oil finishes preserve the tactile feel of the wood. They’re particularly suited to spaces where a subtle, natural atmosphere is desired – such as living rooms, studies, or bedrooms.
Benefits:
Enhances texture and grain depth
Maintains a gently matte, natural appearance
Simple to touch up in small areas
Considerations:
Less durable than hardwax oil or film finishes
Requires more frequent maintenance in high-use areas
Oil finishes are a classic choice for homeowners who prioritise character and comfort over maximum surface protection.
For homes that demand maximum surface protection, especially in high-traffic areas or spaces prone to spills and moisture (like kitchens or hallways), a polyurethane finish can be an excellent choice.
Polyurethane forms a tough, protective film on the wood’s surface that guards against scratches, stains, and water damage. There are two main varieties:
Water-based polyurethane: Dries clear, with minimal colour ambering. Great if you want to preserve the natural tone of the wood.
Oil-based polyurethane: Adds warmth and slight amber tone, which can enrich the character of darker or more rustic reclaimed boards.
Benefits:
Excellent abrasion and moisture resistance
Long-lasting protection with minimal maintenance
Suitable for busy family homes and commercial spaces
Considerations:
Film finishes can feel less “natural” underfoot
Repairs often require professional re-application to maintain consistency
When durability is your top priority, polyurethane is a strong contender – especially water-based for a neutral look.
Wax finishes provide a gentle sheen and can be applied on top of other oil or hardwax coatings to add an extra layer of protection. They’re often used in lower-traffic areas or on reclaimed boards with a very rustic aesthetic.
Wax creates a soft, tactile surface that wears gracefully over time. Small scratches can often be buffed out with a fresh layer of wax, making it forgiving for DIY care.
Benefits:
Soft, natural appearance
Simple to maintain with periodic buffing
Enhances tactile experience of the wood
Considerations:
Not as resistant to spills or moisture as oils or film finishes
Requires more frequent topical maintenance
Wax is best suited to serene spaces where ultimate durability isn’t the primary goal.
Selecting the best protective coating isn’t just about durability – it’s also about how you use the space and the look you want to achieve.
High traffic family areas: Water-based polyurethane or hardwax oil
Kitchens and dining rooms: Polyurethane for maximum moisture resistance
Living rooms and bedrooms: Hardwax oil or oil finish for warmth and texture
Rustic or low-use spaces: Wax or a combination of oil + wax
Also consider factors like floor colour, board texture, and light exposure. Some finishes slightly enhance colour or grain contrast, while others dry more neutrally. Your installer or supplier can show samples on your specific boards so you can see the effect before final application.
Even the best finishes perform beautifully when paired with the right care:
Clean regularly with a pH-neutral wood floor cleaner
Avoid excessive water – reclaimed wood and moisture don’t mix
Use felt pads under furniture to reduce scratches
Re-oil or re-coat surface areas as recommended by the product manufacturer
Protect floors from direct sunlight where possible to minimise colour shifts
Routine care extends the life of your floor and preserves that beautiful reclaimed character.
The right protective coating doesn’t just safeguard your reclaimed wood – it celebrates its history, texture, and warmth. From the natural, tactile appeal of oils and hardwax oils to the robust resilience of polyurethane, every finish offers a different balance of beauty and performance.
