Just use it. Don't forget these labels have to cover people who may
work with these substances day in, day out and are to protect the
manufacturer for the 1 in 1000 or those that have a problem.
Occasional exposure for short periods is almost zero risk.

Just make sure the area is ventilated, use the stuff and leave the

I was worried, as I have just spent three weeks in hospital, for
respiratory troubles. So warnings about breathing problems got my

Keep a bag of Wickes fine surface filler that is out

of the hole with any suitable filling material like cardboard/papermache
and overfill with quick setting filler.
