Hi, Injust had my oak floor sanded and varnished, the result is good except I have visible streaks throughout the floor, obviously caused by the drum sander they used. They say the floor was very damaged and this was the best they could do! my question is what are the options to put this right? should they have finished with an orbital sander as example? just trying to empower myself for a meeting with the company that carried this out tomorrow. thanks everyone!
That is awful, looks like it needed going over with the belt sander again, then a finishing sander such as an orbital. Just out of curiosity, did they make much dust?
No dust issues - we were away but I do have a camera in the living room so played it back to see what they did, they seemed to prep with an orbital and hand sander and then I reckon they figured a drum sander would give a better finish........I would have thought though it would need more sanding after that - and you just confirmed for me! thank you!
Also, the picture framing round the edges is probably caused by the sanding pattern of the two different types of machine, which is why they should have used a finishing sander to give the same finish to the edges and the field
The process as it appears on camera - they filled the gaps, they sanded with hand sanders, they then used the drum sander all over, they then applied two coats of varnish. Now I guess they would need to sand off the varnish and from what you are saying, probably drum sand again, then use an orbital sander to finish? B
I'd say they did because originally they had an orbital sander in the kitchen which I guess was theirs, later the drum sander arrived.
Should have taken at least 3 grits of sandpaper, that's 3 times with the drum sander, before they got to the finishing machines
so just went through the two days - they used the orbital, didn't like the results brought in the drum sander and Yes - just looked at the video again, they used orbital, seemed to be not happy brought in the drum sander, did one run, then hoovered and then painted. You are right. They needed to do at least two more rounds with the drum, then used an orbital to finish. Well the good news no harm done bad news they need to start again! They tried to tell me "it's because the floor is uneven".
each round of drum roller would have progressively higher or lower grit? what grit would you typically reccommend?
I would of gone drum sander first. Either start with a 36 or a 50 grit. Then again with 80 then 100. 45 degrees not straight up and down. Edger using 36 or 50 then 80. Orbital sander throughout with 80 then 100. prime then first coat, then orbital all over with 120 then a further 2 coats. Obviously not all on the same day most do 2 coats only but I prefer 3.
