"Have used this in the past for sanitary products in my bathroom. Due to a damp problem on one wall, I had to remove the sink so the mastic had to be removed. This required another tube so again went for the same product as could not fault its performance over the last year"

Review 8 for Unibond 1439770 Sanitary Sealant White 300ml
"I used this to seal in my bath and shower. It started leaking a month later which I thought was down to movement in the bath but on removing it I found that it had never cured properly (I left it 24hours on a 5mm bead). Given everyone else loved this product maybe I had a bad tube. It didn't get mouldy but it was only in use for a month.
Have gone back to my tried and tested Mapei Mapesil."
