Disaster Staining Floor

[getonwithit]

I hired a industrial sander and sanded off all the mega in my kitchen and hall floor which had yellowed with age it is a solid wood floor and sands back to a very pale light pine colour I don't know what the wood is , I then used a
Myland wood stain in brown oak as I want a darker floor which I then wanted to eventually oil with danish oil , the floor is now looking herendous almost black in some places and the stain has almost not taken at all in some areas all the lines from the edge ofsander show ,it looks a total mess I have left it for a couple of days to settle but have now started to sand it all off ,the mylands stain was very expensive and is water based what has gone wrong ? Thanks

Oh, what a shame. I hope someone can help you. What a disaster! It must look awful.

Just guessing here but if the sanding lines show it sounds like you needed to finish the sanding with lighter grades of abrasive paper to remove deeper scratches. Unsure about the stain not taking in some parts. Maybe the original surface wax (or whatever) went deeper than you thought and is shrugging the stain off ? If so you may need to sand further.

Or maybe hire a professional to redo the job ?

Also oak can come in various shades. Sounds like you may have one darker than you anticipated. Try a light oak first, and if too light try a medium over the top ?

Yes I think I needed a much finer paper for the last sand will have to hire a sander again maybe a spinning disc type , I have sanded countless Victorian floor boards over the years I think this wood is much more delicate ,I tried sample wood stains on prices of 2x1 and the brown oak I was happy with ,
Thanks for all your help

Natural wood flooring can be very porous especially after sanding. I think you will have to sand it again and look for a more suitable product.

I don't know if you've done this, but it's always a good idea to rent two sanders for floors. The big drum one plus the smaller circular sander with the two handles on the top of it.

I think OG is right when he said that some areas must have a lot of deeply embedded grease or varnish. That would explain the bits where the stain didn't take.

Wood dyes need a well sanded uniform surface to take evenly. To be honest, with an old floor, I wouldn't even attempt it. There are plenty of floor sealers around, but all the ones I've ever seen are clear, not coloured. "Junckers Strong" and "Dulux Diamond" are my favourites.

I'm sorry you have had such a disaster. It's going to take a lot of sanding to accept a dye successfully. Perhaps you could look at using a coloured varnish stain. A finish with the colour actually included in the varnish will be more successful.
