How can I salvage this flooring (should I?!)

[Flora]

Hello, new user here looking for some advice. I am restoring an old cottage build in 1800s. Have removed ancient carpet in living room and hallway, discovered very old boards which so far I have just been cleaning as they were covered in dried plaster. Now looking for advice on what to do next once the clean is complete. There are different stains in different parts of the room, a couple of big gouges and splintering, but in general it seems to be in good condition and I'd like to keep it exposed with some rugs on top.

I don't mind the different colours and I really love all the old scratches and marks as it shows the history of the building. But I think it does need some level of sanding and refinish to ensure there aren't any splinters. Looking for advice about how to proceed, pls bear in mind I have NEVER done this before, and also that I am not looking to achieve an "as new" finish, I want to preserve rather than strip it back completely. The boards are pretty uneven and from what I have read a drum sander will potentially be too aggressive (and also tricky for a beginner, especially in narrow hallway).

Morning, I would avoid the large drum and belt sanders for the advice already given, noise, dust and knackered sheets if not fixed correctly.

 

If you are prepared to spend a lot of time on your knees I would use good quality sheet sander and a detail sander for the corners and against the skirting.

Do a test with different grade sanding sheets / rolls and then proceed.

Good quality dust mask and extraction if possible.

Lovely view from the window.

Do this before others encourage you to rip it all out, fit UFH, ASHP and external wall insulation!!

Enjoy the Forum.

What @Nestor is saying above is frankly, going to take you a lifetime. Belt sanders can be bought cheaply, and the use of them can be mastered in 10 minutes.

Due to the age of the property, i expect that underneath the floorboards is ventilated. The biggest issue will be that a lot of your expensive heat is going to be going through all the small holes between your floorboard, and will be washed away under your house. It's a nice idea, but i think you might be dissapointed in the end. Not about the boards, but about the cold.
