I recently bought some replacement jets for the nozzle and they cost £30 each. Nothing cheap with Falch but does save a ton of time. If I had constant work then I would buy another one. This would mean I have one for roofs and one for monoblock because at the moment I need to swap it over all the time.
What would you say is the best dilution of hypo starting at 15% for a roof clean? Also do you have to rinse the hypo off or is it best to leave it up there to do it’s magic? Got the roof clean in question booked in at £600. I think it maybe slightly under priced but wasn’t too bothered as it’s my first one and was really using it as a learn I curve although I have been practicing on my own property. Since advertising it I have also acquired a good few render and stonework cleans.
How long did your Marshall stuff take to arrive? I’ve just ordered a loaf of stuff off them and although their website says expected 28 days delivery I’m a little sceptical of the recent reviews they’ve had.
What is the roof surface made of concrete or slate ??? If concrete a stronger mix would be better as the tiles will absorb some of the mix you want the hypo on the surface not being absorbed intimacy the tile , wet the roof down well before applying the mix with a hose pipe , them apply a mix of 4-1 again strength of mix is dependant on what you are trying to kill/ accomplish, a stronger mix up to 50/50 can be used , just keel applying it and keep it wet for up to 30-40 muinits , it does need rinsing off or you will find it will turn white with salt deposits as the hypo breaks down
