Bill Seidel wasn’t surprised to hear of another new high-rise apartment building in Los Angeles failing so soon. But he was still unsure of how to best tackle this problem job that his painting and finishing contracting firm, Streamline Finishes, had won the bid to come in and fix.

The problem:

The exterior of the six-story building hadn’t originally been primed correctly when it was built two years prior, and paint went on too early. As a result, moisture seeped into the façade as soon as the first rain fell, and it quickly grew into efflorescence. The paint needed to come off before recoating the entire building’s exterior.

The solution:

Seidel tried “grinding, sanding, stripping, medium-blasting, nothing would take this off without damaging the plaster,” he said.

After trying 15 paint strippers, Seidel found PROSOCO’s Enviro Klean Safety Peel 1, which he liked because it doesn’t contain methylene chloride or methanol.

It also doesn’t require neutralization, as many paint strippers do, to restore pH balance and enable paint to bond to the substrate. This allowed Seidel to skip the step of neutralizing, saving him labor, time and money.
