Hi all,
Would it be ok to seal chipboard with PVA and if so, at what ratio to
water, number of coats etc? This is piece will be going under a WC, btw.
cheers,
cd.

Note: "Waterproof" is not the same as "suitable for building a swimming pool"
but it should be OK under a WC.

In article <m6rpku$gaj$1...@dont-email.me>,
Set PVA is water soluble, so that won't work.
Is the aim to handle bad aim ;-) or a potentially leaking toilet?
Bathroom flooring grade chipboard (usuaully with a faint green stain)
will not rot when it gets wet, but it will probably still soak up
piss and smell.

You are right that just because something can be diluted with water
doesn't mean it's water soluble once set, but you are wrong to say
PVA is not water soluble once set, because it is - it causes the
polymer to slowly break down into acetic acid (which itself can go
on to damage some other materials in contact with the PVA).
If you want a similar product which is not water soluble once set,
that would be SBR.

PVA also supports mold growth, which might be an issue if used in
a humid/moist application.

Flawed logic at work here, I think. Just because PVA can be diluted with
water doesn't mean it remains water soluble after having been brushed on
and had the chance to dry out. If that were true, half the exterior
masonry paints you can get would be useless.

A lot more than half of them ARE useless.
