I've just bought a cheap bench - all fine except it has untreated a 5mm MDF shelf and top.
As it's in the cellar, which isn't bone dry, I thought it best to seal it. I've got some PVA (just normal evostick, not the waterproof variety)
- would a watered down version of that work?
A google search suggests that it might not - contact with moisture would make it return to liquid, or somesuch, and to use specialist MDF sealant. But a lot of differing opinions.
