Galleria Classic Rustic Oak 189mm Unfinished Engineered Flooring is 189mm wide, has a total thickness of 14mm and comes in standard lengths of 1860mm. The floor has a 3.0mm hardwood layer which if need can be sanded and re-finished up to 4 times, but under a normal maintenance program and in a domestic environment the floor should not need to be sanded for around 20 years.This is a 3 ply engineered floor so it is made from 3 different layers, one being the hardwood wear layer with the other 2 being constructed from spruce.Each of the planks has bevelled edges (V Grooves) on the two long sides resulting in very distinctive groove between the planks, adding more depth and dimension along with giving an individual definition to each plank.The rustic grade of this hardwood is a very vibrant colourful floor full of character and excitement. The floor can display heavy grain markings, figuring, mineral streaks, colour variations, sapwood and frequent knots of varying sizes. Knot holes, checks splits and other imperfections are allowed, filled and finished. This floor comes sanded but unfinished, ready for the installers to finish the floor how the customer wishes. With the use of different colour stains and oils this allows you to really create a bespoke floor.
