Am I right in thinking it is best to use solvent (ie, not water) based
primer for chipboard? I have found a tin of aluminium wood primer. Is
there anything to stop me using that?

The background is that the chipboard was damaged (and swollen) and I
had to rub it down so I don't want it to become swollen again.

Thanks

Personally I would use something intended for another
purpose, like IsoFlex Special Primer. This is intended for
sealing concrete or sound felt roofing prior to coating with
Isoflex itself.

If the chipboard has swollen and is going to be used as flooring
then its strength will have been compromised, so a solvent-based
substance to soak in and seal all the fibres would be a good
idea.

Wickes sell Isoflex. Wilco used to do 'old fashioned' solvent
wood primer (haven't been in for a while).

But this aluminium primer is solvent-based.

Is it a floor?
If so consider replacing for strength. Swollen chip sounds like
it's already well on the way to turning back into

No, it's a window ledge. It is rock solid as I stood on it this
morning for another reason. All that is wrong with it is that it is
very slightly raised where the accident (leaking bottle) occurred and
I wanted to make it level before repainting.

I found a tin of solvent based aluminium wood primer, which I thought
would be ideal, but decided to check with some experts first.

How do I tell the difference? It is the colour of cardboard, and
dull. It could well be MDF.

If it is MDF, what are the prospects of using Dulux solvent based
aluminium wood primer?

There are 'special' MDF primers, which presumably don't raise the
'grain' (or the fibres in the case of MDF). If you have already
allowed some of it to get wet, maybe a small tin of ronseal
wood hardener might be appropriate before using a primer.

Its MDF. Sorry about the confusion.

The MDF is in surprisingly good condition considering it suffered from
a leaking bottle of some chemical cleaning agent that dissolved the
paint. It is now dry and solid.

I am happy to join the two metre queue and buy a tin of MDF primer but
before doing so I just wondered what would stop me using the aluminium
wood primer I already have (and will be using on some wood), which is
solvent based. I know water is to be avoided.

Looking at following posts and seeing that you are using solvent-based
paint, I would suggest that you try P5(?) chipboard and water-based primer.
Solvent might attack the binding substance and water will attack wheetabix.
I used P5 in the loft; some of it got rather wet when it was stacked outside
(no rain forcast...!) but even the exposed innards weren't affected. The
surface is so hard that I had to use a drill to start the countersink for
the screw holes.
Note: where ther's a danger of a drill 'picking up', a masonary bit does a
good job of 'scraping' a hole.

I met a 2 metre distance queue at a local decorators merchant, on Monday.
Two people ahead of me, it didn't take too long and it wasn't raining.

You can use any oil based primer.

How did the damp get in the first place, through the edges. If its near
water I ended up putting those plastic edging strips over the edges and part
way down the sides. Its a pity makers of units don't use some kind of water
resistant material fo or units so exposed.

Including an aerosol can of car primer !.

But I think he is keen to avoid an unnecessary trip and use aluminium
primer.

Dulux say is suitable for all hardwood and softwoods, MDF is just
sawdust 'glued' together, so I guess it won't hurt. It's main
use is for resinous hardwoods or old creosoted timber (!!).

No, it was a bottle of some cleaning chemical with a tiny hole in it.
The pool did not spread very far, nowhere near the edges. It did,
however strip off all the paint. The MDF is now fully dry and showing
no signs of damage other than a very small amount of swelling, which I
intend to sand down.
