i was using 6mm dash there and every now and then i had a big lump of pebble get stuck. You can see the size of the nozzle, it will spray anything that goes through it. we can discuss rates if you want give me a bell.
dashing wont take long and so you wont need the kit for long.
you can use a wheelbarrow to fill it, just get your man to keep it full, ground level you can scoop outa the trays
That back was very awkward with them pipes, windows, cables hanging down, stupid scaffold blah blah and i dashed it complete in 1 hr 40 mins all swept up with 2 young apprentices. we have a load of these to do and a back like that usually takes us about 3 hrs without cleaning. Sometimes i get another spread in and it takes us about 1hr 30mins but he cost Â£150 a day.
the advantage here is by the end of day one both apprentices can use the gun and spray the reciever on
