To elucidate a bit on Colin's postwith the equipment you have, change the chem to SPM and you will do better than with your DF chem.get a cheap rotary with a shampoo brush, rotary can be as little as £80 and new shampoo brush can be £65 and you can attempt anything.ducks down and put's on tin hat
SPM, CRB, good porty (Jag) and a Zeta at 90 degrees! And it'd have eaten black top for breakfast...
Phil,I am not sure on this but because the restore brush is made of alloy, perhaps you can have the heater turned on? This would probably help quite a bit. As for blacktop, it's different from "normal" heavy soiling (which Restore is great on) and I've found Bactoshield fairly effective. If in doubt ask Shaun for advice. He's the main man.If there are two of us working, then one does the vacuuming then switches to the (separate) scrubbing machine. This will have either the PP brush or an XR scrub pad attached. The second person follows up using the DF machine throughout.
Buy yourself a reasonably good hwe set up even if you have to borrow the money.
That is defo not what blacktop looks like thats just a dirty carpetTony
If you got paid for this job then count yourself lucky and put the money toward a HWE portable. The next time you get a job like this get an experienced guy on the job with you and split the money. You will learn far more than posting on here.
