Well it's been a bit quiet of the Forum lately, so everybody grab a cream cake......
The walls of the GCF thread are already covered in jelly and custard so I started a new fight over here.
MDF
There I said it.
A year or two back, a certain Antipodean framer who shall remain nameless (Hi Ormond.

) said that MDF was a magnet for mold. I hadn't at that time actually seen this happen and I said so. But just to demonstrate that I do take notice of what people say, I started putting a polypropylene membrane under the MDF. Just to be on the safe side. Thus combining the strength and rigidity of MDF with the water-resistance of that corrugated cornflake packet stuff and that plastic crumbly stuff. (Sorry. I'm allowed One surely?

). Anyhow, a few weeks back someone did bring a framed picture of mine back that had been on a less-than-dry wall and the back did have a big moldy patch. Inside and out. But, the membrane did it's job and not a trace of damp penetration. Artwork totally unaffected. And yes, I did replace the back. With another piece of MDF.

But I did tell the customer not to hang it on the same wall.
Of course there is no way of telling if the same thing would have happened with 'alternative' backings. (Ok. Two.

)
Wasn't that a nice story?
No "Don't call me Surely" cracks please.
