i've just glued some pink fire-proof plasterboard to the new metal beam
but have realised i've done it the wrong way round,
i've glued the pink side which should be on the outside..

does this matter?

should i rip it down and do it the other way round
or is it ok?

Its not OK.
You may be able to stick some more on top the right way around but you need
to check with the manufacturer.
