Hi Peter
Long time no speak.
I have extensive experience of using Osmo and Surfix.
I started using Osmo Polix oil about 6 years on Oak flooring, as yet I have not had to go back and reseal any of those floors. That is using a two coat system. I have also used Osmo on Oak worktops and table tops, if you apply the coats very thinly and wipe dry with a clean rag after about 15-20 mins the finish you are left with is far more superior. Another little tip when second coat of oil is dry hit with 320 grit very light sand then add liquid wax and buff, the finish is first class. As good if not better than any finishing oil I have used before.
As you know I have fallen hook line and sinker for the festoys so when Surfix came out I had to have it.
I have all 3 types I have used the heavy duty oil the most. I have bought the green & white vlois and may I say I have used them in my opinion I think Surfix is a waste of money and time.
My reasons, the finish, is not any better than the Osmo using only two coats
The rigmarole of finishing to 240 grit applying the oil and then weighting the 15mins to use the green vlois, then drying with a cloth. Second coat sand to 320grit apply oil weight 15 mins then use white vlois and dry again the finished effect is great but no better than Osmo paint on and wipe off
The pads in the boxes get clogged up and the do dry out so when you come to use it next time you have to change the pad more expense.
Not as cost effective as Osmo
Not very good at covering any thing that's not flat.
The positives about Surfix. You can put oil on quickly and cleanly
The finish is good but no better than the Osmo
I now pour Osmo into the Surfix container and continue that way the best of both.
If you want any more info on oiling wood pm me and I will give you a call
