Limestone siding
So I run a small company for about a year now that mostly I focus on driveways/sidewalks flat surfaces etc, but every now and again I get customers that want house exteriors done, depending on the level of difficulty I’ll do them. I’ve done limestone before using just SH and had sort of a mixed results, I’ve got a customer that I did there driveway/sidewalks already but wants one side of there houses that has a little algae/mold build up as you can see in pic hit too. With how mild the growth is, for those who have treated limestone siding like this in the past, do you think a pump up sprayer with 6ish% SH and some dawn and of course some light pressure washing after would do the trick?
