WASH-IT H.B.
New member
I went to do a treatment on an asphalt tile roof today. I was using SH, h2o and dishwash liquid. The ratios were 1>SH to 2>H2O to 200mls dishwash.
Because I can't get my downstream to apply treatment without watering it down all to hell I put it on with an electric back pack sprayer. I DON'T HAVE A ROOF PUMP!!. The Tiles are VERY black with them being nice and clean anywhere there is a lead flashing around back vent pipes etc.
I applied VERY liberally the roof mix [which I found on here] let it dwell for 15-20 minutes and then proceeded to rinse [owners request]. The water came off soapy [to be expected] and orange to brown. Obviously the formula was working but the tiles are still black but not as black as when I started.
The house is right by the coast and it is the south and east facing rooflines that are black {Southern hemisphere}
I have watched the video's of you guys applying you roof mix and the change appears to be all but instant.
Where am I going wrong?? I am suspicious of the viability of the SH. I bought it this week but it could have been in my suppliers stock for some time.
And NO I CAN"T GET ROOF SNOT I'm in New Zealand but if anyone wishes to share with me the roof snot formula, by all means feel free I'd love to have it.
Would make my life easier.
Any help is good help. In anticipation thanks guys.
