Grading of Timber

AB Select/Nature Grade

Planks are selected to give grain and colour variation. There can be a small amount of light sapwood around the edge of the board. Small sound knots and smaller filled knots also add to the natural effect.

ABC Mixed Grade

Popular in species such as walnut. This grade displays more variation in grain and colour with larger sound & filled knots with more sapwood well distributed. Small filled cracks and dark streaks are also apparent.

CD Rustic Grade

More economical timber selection allows for more grain and colour variation with large sound knots and more filled knots well distributed. Small filled cracks and dark streaks are also apparent.

Different Finishes


The top layer is spray coated with five primer coats and at least two top coats of Treffert aluminium oxide lacquer which is UV cured. The finish can range from matt to gloss. The result is a smooth hard wearing and low maintenance surface which enhances the natural grain and beauty of the wood.

Natural Oil

Up to four coats of natural WOCA oil are applied by rollers, each coat is buffed into the top layer permeating the grain and adding a matt sheen to the surface which is then left to cure. This finish is the most natural of any, creating a deep lustre whilst maintaining a tactile surface.

UV Oil

Up to four coats of natural WOCA oil are applied by rollers and buffed into the top layer permeating the grain. Each coat is cured under ultra-violet light creating a slight satin sheen on the surface. This finish combines the natural lustre of the oil with a tougher surface finish.

Different Textures/Surfaces


A steel brush removes the soft grain from the surface layer creating a textured surface which enhances the beauty of the natural grain. Brushing is often used with stained products.

Hand Scraped

This process can only be done well by experienced craftsmen using traditional hand tools to scrape out the soft grain whilst expertly following the woods natural contours. The result is an undulating smooth surface.


To create this effect various methods are used to give the wood an aged well used appearance also that of a board milled using rudimentary rustic tools. The skill is in making the distressing look natural.


Stain is applied by rollers and buffed in to penetrate the top surface of the board and then sealed with either oil or lacquer creating some stand out floors.


Timber is stored in drying rooms filled with ammonia vapour or smoke for up to 3 days until the wood colour darkens. This means that the floor keeps its rich colour even after refinishing.


Timber is baked in a kiln room and the soft grain is consumed. The effect is dramatic causing the wood to blacken with an exposed textured grain; a hard wearing surface which retains its colour after refinishing.
