Hello

Im going to be tiling the front of my bath which I have made
from 12mm marine ply (as discussed a few months back)

It was also said to seal it with diluted PVA to stop the tile
adhesive soaking in to the wood to quickly.

What ratio water to PVA is it.

It's often listed on the PVA container; the last time I did some
sealing -- of some previously-untreated artex, before painting --
it recommended 5 parts water to 1 part PVA.

Add and mix in the water slowly initially.
If you pour all the water in one go, you end up with
a bucket of water with globs of PVA floating in it,
which is difficult to mix.

I did it the other way 'round, but with the same gradual approach. (I
put the 5 parts water in a bucket, then -- slowly -- added the PVA,
with constant stirring; it seemed to work OK.)
