changing some misted up glass units no more than 300 mm sq, is it possible wrong silcone could have been used in the first place, if so what the correct 1 to use
The correct silicon to use is low mod neutral cure. as if you use high mod or assatoxic cure the assertones can damage the perimeter seal to a double glazed unit.
You need to ask the shop for low-modulus because the acetone in the high-modulus stuff will attack the sealing system on your glazing unit. Low modulus takes a long time to go off though.
