Does the oak need any further protection immediately after it has been installed?

It is prudent to apply Osmo Polyx Oil (product code clear matt 3062) to the newly installed floor to give greater durability and stain protection. This treatment is especially recommended in areas of high traffic such as hallways, kitchens and any commercial premises. Always test an area to check you are satisfied with the appearance once dried before applying to the whole floor.

What is the best way to clean the engineered oak floor?

If the Polyx Oil has been applied then the compatible cleaning product is Osmo Wash & Care cleaner, always follow the manufacturer’s instructions. This cleaner is also recommended even if the Polyx Oil has not been applied.

General advice: Hoover as normal, mop up any spills with a damp cloth and keep your mopping to a minimum. Mop as dry as possible using a damp not saturated mop and never allow any surface water to stand.

What is the best way to install engineered oak?

The correct answer depends on your sub-floor. Briefly: if the sub-floor is concrete/screed, it must be dry and level then the best way forward is to fully bond the engineered oak board to the sub-floor by using a suitable adhesive. This dries like a hard rubber and never becomes brittle over time. If the sub-floor is timber, then you can either install as above using a suitable adhesive though the sub-floor does require priming first with a weak solution of PVA glue, or, if the board is 20mm thick, you can secret nail/screw the boards to the timber sub-floor. We only recommend a floating installation (not directly secured to the sub-floor and using an underlay) if you have different substrates within the same installation e.g. old timber substrate running into a new screed sub-floor.

 

Do I need an underlay?

Only if you have two separate substrates as outlined above. You may have specific issues that require a specialist underlay e.g. noise reduction, insulation and only your installer can guide you here. Please note we do not stock any fixing products for engineered oak including underlay.

What thickness of engineered oak board should I use?

We offer both 15mm and 20mm thick boards. If the board is to be fully bonded then either thickness is suitable. If the board is to be floated then both are suitable however the 20mm thick board will have less movement overtime so is preferable. If you are secret nailing or secret screwing the board then only 20mm is suitable.

Can I use engineered oak with underfloor heating?

There 2 common types of underfloor heating: wet, which is piped and part of the central heating system and then electric which is separate from the central heating system. Engineered oak can be used with both however a maximum thickness of 15mm only should be used on electric.
