Jarrah - Osmo Floorboard Finish

[arockandroad]

I’ve recently sanded back and finished my Jarrah floorboards with an Osmo Polyx Hardwax Oil (semi-Matt) finish. Boards were sanded back with 40-60-80 and finally 120 grit. Then vacuumed twice, mopped then vacuumed again. Thoroughly stirred tins prior to application. Applied first coat with microfiber roller then waited approximately 12hours and applied the second coat. Now it has been drying for 3 days since the second coat and is completely dry to the touch, however, a few areas in certain lights show an overlap of the finish. It appears slightly glossier than the surrounding areas and is clearly an overlap of the roller. Most of the floor came out beautiful but these few areas are starting to concern me that they are not blending with the surrounding finish. Can anyone advise on what may have happened and any ways to possibly blend these areas with the surrounding (eg light sanding and reapplying? - they market this product on its diy and easy to touch up) ? Or since it’s still in the curing stage (10-14 days) should I wait it out and hope it blends on its own? TIA

I have not applied it to floors but on tables this happens when too much is applied. Whenever I do this I just sand back area with some 240 with ROS, not down to the timber but so it looks pretty even, and then apply a thin layer. Easiest way to apply thin layer is to wipe it on with just a rag and then leaving it for a few mins and wipe off with clean rag.

Osmo recommends applying this stuff with a natural bristle brush, rather than microfibre roller unless you are VERY experienced with the product. The reason for this is that it is too easy to apply too much with the roller. It needs to go on very thinly, otherwise, as you have experienced, it takes a great deal of time to dry and will dry with a soft 'skin'. I did this with my first application to my bathroom vanity top. Lesson learned.

In addition and from memory, Jarrah is quite an 'oily' hardwood timber and should first be 'washed' with a solvent, such as the Osmo brush cleaner or citrus based turps to remove the surface oily layer.

I've just put Spotted Gum down and intend on using a layer of this first:

Woodwax Clear Extra Thin - Natural Timber Oils Victoria (https://www.naturaltimberoils.com.au/timber-oils/categories/interior-timber-finishes/woodwax-clear-extra-thin/)

Then a layer of the normal Polyx Hardwax oil, again, thinly.

Ya gotta follow the instructions to the letter with this stuff, but once you master it, it's unbeatable IMHO.
