Many silicone-treated surfaces do not accept paint, at least not water-based paint (not sure about oil-based paint). Is there anything I can treat a silicone surface to make it wettable by a water-based paint?
Angle grinder?
afaik no. There may be some specialist primer out there somewhere.
Is this of any help?
Some youtube videos suggest that putting a non-silicon caulking over the top allows painting.
That looks a possibility - I'll give it a try. Thanks.
