Happy Sunday.
Here is a picture of a section of my Pennsy Block retaining walls. A friend has a mold so I cast some out of plaster, I got tired of the typical Grey and went for another color. The plaster when thoroughly dried were stained with a watered down Woodland Scenics Burnt Umber. After the stain dried I took some hard pastels chalk and scraper off some black and Dark Brown then worked it on with a "DRY" brush. Last I sealed each section with Dullcote. What colors are your retaining walls?
BTW the 2-8-Consolidation was weathered by Harry Hieke
Lets see what you have this week
