Masking Adjacent Surfaces

Waterproofing Block at the Bruneau Observatory | PRO Painting Tips
What happens here
Prepare the work area by meticulously masking any adjacent surfaces that should not receive the sealer, such as metal door jambs and curved metal work. Use painter's tape, specifically FrogTape Green, and masking paper or film. For applying the masking paper quickly and efficiently, a 3M Hand Masker can be utilized. This is critical because silicone-based sealers are difficult to remove from unintended surfaces and will prevent paint adhesion if the adjacent surfaces are meant to be painted later.
Goal: Thoroughly mask all surfaces adjacent to the cinder blocks, including metal door jambs and curved metal sections, using painter's tape and masking paper to prevent silicone sealer overspray and adhesion issues.
