Been using Treatex stain and hardwax oil this week and really impressed with it! Last time I used a hardwax oil it was the bona oil and i couldnt get on with it (putting it on with a brush as they said to didnt help) Stain goes on really well and blends great.
I use Osmo as a rule, most of time I will use a Roller and Brush as I have never been a lover of the Oiling Brush. Have you tried a Double Blade Scraper and then buffing it with a buffing cloth on a buffer? I find it a lot easier to apply the Osmo oils/tints etc and there 2K oil with the blade, takes a while to get used to but worth it as you don't go through tonnes of cloths. From as much as I know the chap who runs Treatex was from Osmo originally.
I used a mohair roller and brush for the edges and it blended really well. Put the stain on with a buffer. What's this scraper then? Who makes them?
I came away from the mohair rollers the ones I use never gave a consistant finish, I use Microstar rollers for both Oil and Lacquer and they give me a great finish on both but I suppose pardon the pun its different strokes for different folks. The Double Blade Scraper is great for tints as I said above as you will only put a thin coat on the floor but it really loosens the oil up and makes it easy to move but the Europeans have been applying oil like it for years. Once you've got a an area done then buff it in. Its a bit painful on the wrists to start off but once you get the knack of it you'll never go back. One thing to bear in mind its only good for wood floors that have no gaps down the side of each board as you'll lose loads of it, so parquet and engineered are in but floorboards unless slivered or filled is a no no.. http://osmouk.com/sitechapter.cfm?chapter=64&page=0 https://www.youtube.com/watch?v=HhDZSbm21EM
Ha ha wouldn't know, I've never wall papered in my life. But if I had to guess I'd say yes but the osmo blade has another bit at the back strengthen it when scraping the oil across the floor.
