I have been recently offering to lay down a mixture of softwashing chemical on pavers to help prevent the regrowth of moss and plants in the cracks and have had great success.
My question is will the same get up work for killing and removing organic matter from an asphalt driveway without causing damage? It seems to be a persistent problem many homeowners/municipalities experience and I am trying to capitalize on it.
You do not want to Softwash asphalt. Especially newly sealocated asphalt. our chems can stain then orange and white. They will have an adverse effect on the oils.
If it is a real old asphalt driveway it can be softwashed. You just have a clean old driveway needing seal coating. Stay away from the freshly sealed asphalt. We've done a couple with on problems. Most of the oils are off of the surface if old. No real profit chasing that work, but it can be a safety concern if moss is creating a slippery surface.
Spencer, this is the scourge of the NW - moss on asphalt driveways. It is a very real problem that I have still not dialed in, despite being in the exterior cleaning arena for 17 years.
Pressure washing will scar the asphalt before it will get all the moss out. Maybe you and I should put our heads together and come up with a good solution for this...
