Anyone who has the luxury of an old 1900s timber floorboards is, in my view a very fortunate Houzzer and would have a very difficult time trying to get anything today that remotely resembled those boards. I have a Queenslander from that era. All Queenslanders has tongue and groove Hoop PIne floors and they were nearly always covered in newspapers with "lino" ( made in England) over the top...so were well preserved. The advice I received about these untouched floorboards that had been seasoned naturally for many years prior to use was to initially "feed them" with a mix of kerosene and pale boiled linseed oil and then stain them if I wanted then give them a couple of sealant coats that would still allow them to breathe. I opted for just a kero and pale boiled linseed oil sprayover whenever they looked "thirsty" and I've used thick rugs to protect them from wear and tear. I've had them like this for 30 yrs or so and am very, very happy with my floors...and they are soft wood. Every couple of years I douse the floors with turpentine as this penetrates the timber and prevents termites, then continue on with the stain, kero and linseed oil mix...then get them buffed. That's just my story that may be or not a little helpful, I was born in Victoria so am familiar with the balck Japan satin that was used down the boards exposed each side of the hall runners....and the boards were the wider ones. Its a pity that multiple sandings compromise the tongue and groove..sometimes such floors need reinforcing from underneath. After acertaining that, maybe a light.soft timber "overfloor"rather than a hardwood would be the go although quite a bit of maintrnance for the first few years. You could stain it any colour you wanted. by getting a light to mid brown or teak stain and give it several coats allowing drying in between until you were satisfied with the colour. Its a good thing to keep in mind that timber flooring from that era was very well and naturally seasoned for years prior to being sold for use...the idea was to seel people timber that would last. I have put on a couple of decks here and am rather disappointed to see that the newer timbers are showing signs of wear and deterioration whilst the original timbers are still as unblemished and solid as the day they were used to build my old home. I think that was a very good lesson for me. All timbers today are kiln dried for expediency so, since they were not permitted to "age gracefully": and gently they are not naturally strong. If ever I do any more timber renos to this place I will be sourcing old timbers form places being demolished. These often cost more...but there's method in that madness! I'd say to anyone wanting their floors to stand the test of time...Buy old timber and treat it as it would have been treated of old. Should have some photos of these floors somewhere. I'll post them if I can

Hi I am in flooring The floor does not have to be water level you have a allowance of 3mm in 1mt or 6mm it 2mt or 9mm in 3mt get the picture The subfloor does have to be hard and smooth But you CAN NOT put the kitchen on the floating floor, the floating floor needs to be able to expand and contract with a min of 10 mm expansion or 1.5mm for every 1mt so a 10mt long room needs 15 mm expansion gap at ether end. Ask the kitchen supplier if he can leave the kick boards of a put them on are the floor is installed

Hi monicafowler96 There are pros and cons for either a solid hardwood timber flooring or a quality engineered flooring. Solid will give you a longer life span with more times it can be sanded and refinished but ususally more expensive to lay and finish in the desired finish. A roasted solid timber is a good option if you want a dark floor- also makes it harder and colour penetrates right through. Make sure the timber is acclimatised before laying to minimise movement (shrinkage and expansion) or cupping can occur. A quality engineered flooring with a thick wear layer is often chosen because it still gives you 2-3 sands. It comes prefinished so it's cost effective. Some are smoked so any scratches are minimal in appearance. Check out the Venture plank range from Havwoods for a product with a thick wear layer. https://www.havwoods.com.au/flooringsearch/engineered-timber-flooring/venture-plank Stay away from any of the thin or mdf backed products. Arena Venture plank pictured above Just a further thought- make sure you have alot of natural light if you want a very dark floor and they do require more cleaning as they show the dust. Best wishes

Hi Badobbs Structafloor will only span 600mm unsupported in the 22mm and 450mm in the 19mm version so no, it alone won't fix your issue. A simple fix would be to pull up the floor in the affected area and then 'pack' it up to level, THEN lay some structaflor over the new supported sub floor. This is done by getting a laser level and marking out the low points in the joists then making up packers to suit, or installing a packer and planing it down to suit. It depends on the level of dipping. It will be your cheapest option and definitely a job for your carpenter (unless you're handy). Regarding disturbing the floorboards that is nonsense. If there are other issues such as other sagging floorboards then you can address them at the same time, or fix them down properly with screws. I suspect that the real issue is that the wall removal did not take into account that the floor joists are usually fixed to it and they are now unsupported. If you get under there and find issues with your joists/bearers then it is not a big deal to install a couple of stumps/connect bearers to support them whilst it is open. We do it all the time. Either way laying a new floor over a subfloor without addressing it would be a waste of money and will degrade your new floor. Cheers
