Sorry Nige, if you have a power shower, as Dave rightly points out ( thanks Dave) it isn't suitable. Your only course of action is either rake out and use Microflex or easypoxy grout.Ah,
What else would suggest to use in that case ?
Nige
You could try an epoxy paint on solution....again not sure if suited to power showers, consult the manufacturer for details
