Evening all,
Skimmer booked for upstairs for 2 weeks time and I still have a lot to do before he turns up, gulp.
In the bathrooms and ensuites I have used moisture resistant boards http://www.resistant.co.uk/tilebacker-moisture/ and my query is about these. Some will be tiled over (showers and around bath) and some will be skimmed and some walls will be partly tiled (straight onto the board) with the rest skimmed.
Should I fill in the gaps between the boards? We are not talking of wide gaps here - at most 3mm (with odd cock ups perhaps closer to 5mm - these are very rare), with most boards butted together fairly tightly. I'd hate to think of any water getting behind these boards through these gaps and then tracking down to the ceilings below. I am happy to tank them - I'd rather a 100% solution - peace of mind is better than worry and since I do it all myself the cost isn't a massive consideration. If the general advice is tank - then what products should I stick to?
Thanks in advance.
