In a temper my son decided to crack our wash basin. I presume it's
acrylic.

Has it got fibre-glass re-inforcement?

Are there any glues or methods of repair anyone here can recommend?

It's a coloured suite and I really can't afford to replace
everything.

What colour is it?

I'd sooner have hairline cracks and have it the right colour for the time
being.

Can you get at the underside of it? Is the underside "on show"?

You might be able to use a car body repair kit, the sort which
contain fibre-glass matting. Mix up some resin, fill the crack,
hold it together with stretched-on tape. Peel off the tape when
the resin has set. Patch the basin underneath with matting and
resin. Note, cellulose thinners on a cloth will wipe away resin
before it has set. Test to see what the thinners might do to
your basin before using them, just in case! You can polish the
resin by using wet'n'dry paper, used wet, fine grade. Use 600
grit for finishing off - rub the faces of two pieces together
to wear it a bit for the final polish, which you can use Brasso
for instead of water, then just Brasso on a clean cloth.

You can get clear-casting resin, various "proper" polishes, and
flour-grade wet'n'dry, but *if* polyester resin is compatible
with whatever you've got, the car stuff will do (don't use too
much hardener, or it'll make a pink resin! Clear cast may be
better).

This'll take most of a day, on and off, I should think.
