Thanks for the reply George,

I know the plasterer did use tape underneath maybe he didn't put
enough. I used flexi-filler, and the flexible polyfiller? But didn't
think of using a rubber silicon, is there one you could recommend as
rather go for word of mouth.

Thanks


My guess is as you have stated never used enough, as the wall in my bedroom
had two cracks from floor to ceiling which were foundation movement I used
the method as I stated and putting scrim over the crack horizontaly and
vertically moreso in the crack areas,plastered it and tested it... when dry
by jumping up and down on the floorboards like a madman :-) stll no cracks
11 months on thereabouts?
