Technical spec

The Calder Engineered Natural Oak Brushed and Oiled flooring combines classic natural oak colouring with a textured brushed surface, creating a floor that feels warm, characterful, and authentic underfoot. The oiled finish helps bring out the depth and detail within the grain while maintaining a softer and more natural overall appearance.

Each board measures 180mm wide, offering a slightly wider plank format that helps rooms feel more open and spacious. The broader boards reduce the number of visible joins across the floor, helping create a cleaner and more seamless layout once installed.

The surface is finished with a combination of brushing and oiling. Brushing lightly textures the oak by removing some of the softer grain, helping the natural grain patterns and markings stand out more clearly across the surface. The oil then enhances the natural colouring and character of the oak while allowing the texture and grain detail to remain highly visible.

This is mixed grade oak, meaning knots, tonal variation, and grain movement are all part of the floor’s appearance. These natural details give the flooring more warmth and individuality, ensuring the finished result feels authentic rather than overly uniform.

The flooring uses an engineered multi-layer construction, designed to provide greater stability than solid wood flooring. This helps minimise movement caused by changes in humidity and temperature, making the floor suitable for conservatories and water-based underfloor heating systems. Bathrooms and areas exposed to standing moisture should still be avoided.

With a 15mm overall thickness and a 4mm solid oak wear layer, the floor offers a reassuringly durable feel underfoot while also providing excellent long-term lifespan. The wear layer allows the surface to be sanded and refinished up to three times during its life. In most domestic settings, refinishing is unlikely to be required for many years, but it still offers valuable long-term flexibility.

Installation uses a tongue and groove fitting system, with boards designed to be glued together and typically installed as a floating floor. A 3mm underlay is generally fitted beneath the flooring to help improve sound insulation, heat retention, and provide protection from minor subfloor moisture. For installations over water-based underfloor heating, a 4mm compressed rubber underlay is recommended, with floor surface temperatures kept below 27°C.

As this is an oiled floor, the surface is not fully sealed, so spillages should be cleaned promptly to help avoid moisture marking. One of the advantages of oil is that smaller worn or scratched areas can often be repaired locally without refinishing the entire floor.

Each pack may include starter boards to help create a more natural staggered layout during installation.

When ordering, allow approximately 10% extra for cuts and wastage, plus an additional 5% for natural grading variation.

The Calder Natural Oak Brushed and Oiled has a beautifully natural appearance thanks to the textured brushed surface and softer oiled finish. The wider planks help create a spacious feel, while the natural oak tones make it incredibly versatile across both modern and traditional homes.
