APPLICATION / INSTALLATION DETAILS
Most pure silicone caulkings do not stick well to masonry and cannot be painted -- although special products are made specifically for masonry and some specifically for painting.
If humidity is below 30% RH, mist fresh silicone to help create a skin and avoid dust collection as silicone cures by reaction to moisture, not by drying.
