you not use one of those flat surface cleaners? also how much is your PLI for this. And finally once you have washed the drive do you just use buildrs sand and brush it into the gaps again?
if ye ron msn i would like to chat with you if possible
Not on MSN but feel free to email any questions you have and i'll help where possible:
info@totusonline.co.ukPLI: I've just tacked it on to my window cleaning, gutter, and conservatory cleaning insurance and it went up £100....but i'm sure it depends on how long you've had PLI and if you've claimed before.
Rotary Surface Cleaners:Used one I borrowed but not bought one yet. They do save time as you don't make half as much mess, thus less cleaning up after, and a better hourly rate, but at £450 on top of your initial spend i'd start with the basics get in some dough and then buy one when you can afford it.
I wouldn't feel comfortable using them on all jobs as I've seen some really poor patios with bad pointing and with a rotary cleaner you'll probably blast out the concrete and then you'll have to re-point it
This is where the 25 degree nozzle would come in handy.
Sanding:
Just use Kiln Dried Sand..... about £2.50 a bag this will cover approx 25 m2. Any builders merchant.
Get a stiff brush to brush away all the excess water and crap that flies out of the gaps when doing block paved drives, when you've got rid of all this then give the area "once over" to get rid of any dirt still kicking about. Leave to dry before sanding.
When sanding make sure the drive is completely dry, don't sand as soon as surface is dry as it's the wet areas between the blocks that really need to dry out.... otherwise you'll find that the sand will "drop" and then the custy will want you to come back and re-sand again. Use a soft brush and get something BIG or you'll regret it.
As we are going into the winter months i'm guessing that sanding will make the job a little trickier what with cooler weather and more rain so it could be a couple fo days before you could re-sand. Also make sure that on the day you are going to do it that no cars are going to be on the drive...obvious i know but you'll be p**sed off if you turned up to see Mrs Custy's Beamer still on the drive. ;
Anything else just keep asking... i'm sure other guys will have different views/ideas and more experience than me, but i hope this is giving you a good idea about what you want to do.
