G and Henry and I scrubbed and scrubbed and scrubbed the walls with TSP and hot water, yielding a creepily sticky texture to the vinyl. As a person inclined toward risk taking, I slapped the primer up anyways and rolled on the white dove. A week out everything seems to still be sticking.
For a top coat I rolled on a gallon of Vermont Natural Coatings Poly-Whey in three layers with a light sand with 220 between them. This is a neat product that uses polymers derived from a whey, a byproduct of the cheese industry, which surprisingly, is a pollutant if not treated properly. The finished surface looks great and will make building up from here a lot easier!
