Protection for oak doors?

aliasojo

I know this has been asked before, but people seem to be treating their doors not in accordance with the manufacturer's instructions so I'm wondering if there have been any issues?

I bought Howden's Dordogne Oak doors and wanted to use Osmo Polyx Oil on them and the skirtings & architrave etc. (Although the stuff I have is technically for floors and I see there is now an Osmo door version too.)

Sheet that came with the door states oils and waxes can't be used as the doors have a moisture content that should be sealed in and oils dont do this, they let the door breathe therefore the moisture content will fluctuate with the surrounding temperature and moisture in the air.

I know a few peeps on here have used Osmo or wax anyway regardless of the advice.

My main concerns are the bathroom and kitchen doors, mostly because of the heat/moisture laden air. Also, my joiner removed more than he technically should have, from the bottom of the bathroom door which is concerning me with regard to treatment for it.

I've bought some Sikkens Cetol TSi in clear satin which is classed as a protective woodstain and is recommended, but it's solvent based and I'm concerned about yellowing.

Not sure which way to go. Any advice?

Although the Polyx Oil is an "oil", it is actually a "hard wax oil" so dries to a hard dry finish and it states that it is water repellent - that would seem to suggest that it does actually seal the wood.

When we were considering it for our doors, OH rang Wickes and asked why it said not to use oil or wax. The only answer they could come up with was because the doors were veneered oak and you need to do light sanding before and between coats. Their worry was that the veneer was probably not thick enough to cope with multiple sandings. But if the doors were painted/lacquered/stained/varnished you'd have to do the same. He also rang a couple of Polyx Oil suppliers who both said that if you sand only lightly, and only one or two coats would be needed, then it would be fine.

We've been in six months now and the doors are looking good, the bathroom door remains unaffected but I do have the fan on during and open windows after bath/shower.

Why not ring Osmo and see what they say?

Me too. But I dont want to have to shell out for new doors if they start to delaminate a year down the line.

Me too, or rather OH but I tell him to . That's just reminded me - we had carpet fitted after doors hung, will have to check to see whether any had to be shaved off, I think they were fine though.

It's one sided I believe...i.e. it stops moisture from entering the door but lets it escape from inside the door iyswim. That's the problem, the door manufacturer says the moisture content of the door should remain stable therefore something that acts as a barrier is needed.

It's not to do with the sanding etc it's all about the moisture content of the oak door.

I take it they're veneered, same as ours from Wickes? Seems perhaps Wickes employees don't have enough product knowledge to answer the question we asked .

I think I'd still give Osmo a ring and see what they think, especially seeing as they do a door version.

Yes, they're veneered. As you might have gathered by now, I ask questions constantly. Loads of people haven't got much more than the very basic product knowledge about the things they sell, I've found.

Edit: Called Osmo. They don't recommend their products for doors with more than 20% moisture content and cant comment as to whether delaminating might be a possible occurrance or not. Cue me now shaking my head as I have no idea what the moisture content is of these doors. The door oil is basically the same product as the usual floor Polyx Oil. Marketing at it's best. :rolleyes:

Nor I about our doors, well as ours are done now we'll have to wait and see - pity nobody told us about that in the first place :rolleyes: . I wonder whether Howdens could find out about the moisture content of their doors, you never know, their product knowledge could be a lot better than Wickes .
