The Dome Painting Job
Rich Cassidy on the rope harness and Eric comes to assist again on the right giving some experienced rope climbing advice
Below Rich operates the sprayer while Joe does the back rolling and John mans the paint pump
Triangle by triangle they work thier way around the dome on each level
After completing the upper 3 levels the lower level is then painted
There are 4 triangular levels of the dome shown here highlighted with different colors
The path of painting the upper 3 levels is illustrated below.
Note dark areas indicate areas that are painted last moving down the ladder
1. Starting from the top accessed by ladder on right side of balcony using rope and harness have 50 foot paint hose feed through pipe at top of dome to paint pump below in dome. Start at one side of ladder paint the seams and triangles of level 2 all the way around to the other side of ladder. When painting level 3 paint the tops of the dormers that are connected to those triangles.
2. Once level 2 is painted coil up excess rope so it doesn't drag on the painted triangles on level 2 and paint starting at the ladder level 3 all the way around to the other side of the ladder.
3. Once level 3 is painted coil up excess rope and drop it down pipe hole at the center to get it out of the way of painting level 4 and paint starting at the ladder level 4 all the way around to the other side of the ladder then paint the unpainted path back down the ladder, collapsing the ladder to allow the area underneath the ladder to be painted all the way down to level 1.
4. Once the upper levels of 2, 3 and 4 are painted, use a ladder to move around the dome and paint level 1 all the way to the ground, masking off areas such as the porch and exposed concrete floor to keep unpainted.
The above procedure is for first sealing the dome with concrete primer and allowing to dry overnight and then the same sequence is used to apply the Lexan paint afterwards the next day. Painting is done in the afternoon allowing the dome to cool after painting to avoid air bubbles from increasing heat.

Sealing the dome with silicone
After more than a decade of multiple water leaks coming through the concrete we have been searching for a solution
Map showing all the multiple leaks
Finally we found a local company that was able to give us a coating with a "10 Year Water Tight Warranty"
The company Hoag Roofing and it's workers did a fantastic job.
Below you can see after pressure washing the dome applying a two part expoxy primer.
This is done for optimal adhestion for the final silicone coating called EVER-SILIC® HS which is a single-component
pure elastomeric silicone coating system that provides superior weatherproofing and UV resistance.
