Thought I'd share. Just applied foam inside my cistern to stop Condensation forming on outside during the winter. It's supposed to work so we will see. Not much fun to do with knife and shaving form and sandpaper. Toilet wanted new insides so was on the to do list.Done now. If it all floats up in the next few days I'll go mad. Ha
You know what Wayners - I've often thought about doing that to eliminate the same problem. But I've always thought 'Naaaah that's a stupid idea'. Please let us know if it works !!!!!
Other way is to stick yoga matt inside. Stick with polymer mastic I guess. Tidy You can also stick polystyrene in but cutting that put me off. I went with foam though but second would be yoga matt
Ha. We get dripping all over tiled floor. Gets very wet in winter and dose my nut so fingers crossed it works. Can't see why not. Having now done it next one I'll try joga matt and CT1 or OB1 mastic I think. Can't say I enjoyed the foam application and sanding.
