What is Crag Oak flooring?

Crag Oak is a range of modern pre-finished flooring with a band-sawn appearance. Available in solid or engineered, Crag Oak floorboards are brushed and then scored across their width to produce a band-saw-like finish; scores are deepest and most distinct at the edges of the boards and become less prominent towards the centre. The oak is coloured with specially formulated hydro-stains before being finished with an Osmo Polyx® Hardwax oil. This creates an appealing variation in tone between the horizontal scores, brushed springwood and harder summer wood.

European Oak is widely considered to be the finest available worldwide due to it’s attractive colouring, figuring and durability properties. All Russwood oak flooring originates from the same highest quality raw material, making grade selection purely an aesthetic preference. 

Which colours are available?

Crag boards are supplied pre-finished in a choice of 8 different colours – from coastal whites, through blue-greys, to rich chocolate browns. These colours have been specially formulated to highlight the pronounced grain and beautiful figuring of the oak whilst providing appealing variations in tone between the horizontal scores, brushed springwood and harder summer wood.

We spent a great deal of time investigating wooden flooring suppliers and were immediately impressed with the superb quality and diversity of the products available from Russwood. Perhaps just as importantly, the team were wonderful to deal with; the depth of their knowledge, helpfulness, professionalism and friendliness helped make the project possible.
