What happens here

The project begins by identifying a problem area: an exterior wall stained with soot emanating from an interior gas-burning fireplace. It is crucial to address such stains, as painting directly over them will result in bleed-through and discoloration of the new paint. The surface must first be thoroughly cleaned. In this instance, the wall had already been power washed, leaving residual soot that still requires priming before painting.

Tools and materials

  • Power Washer — Initial cleaning of the exterior surface to remove loose soot
