[mickey07]

ive done quite a bit of smooth rendering but aint done any pebble dashing im afraid,been asked to do a 12 x 6 foot wall and i want to have a pop....just advice needed if you can chaps,ive got no probs puttin the scratch on by the way...

 

[spunky]

Put loads of waterproofer in and make sure it's mixed well through if you're using beads keep you're scratch coat back 5 mm from the beads lay you're butter coat on nice and even take the lines out with you're trowel and throw the stones keeping whatever you're using to throw them flat to the wall or they'll group together if the gear on the Walls too wet it'll push through the stones or too dry they don't stick I'm crap at it mate good luck

Fcuk me he can give a sensible answer at times, Lol

 

[spunky]

That was a good guess then :RpS_lol:

 

[Jace]

youll be fine mate dashing is a peice of piss specially on a wall that size

 

[owls]

it aint a piece of piss if you dont know what you are doing,if it aint done right looks terrible.
a bit more to it then just launching spa at the wall,
ie keeping wet edges and avoiding bald spots etc.

We used to do a lot of pebbledashing, very rarely do we get asked anymore apart from matching up to existing
As others have said, waterproofer in the scratch to kill suction and let your top coat or butter coat mix for as long as possible.
We generally add a shovel of hydrated lime to the top coat to aid plasticity and brighten up the finish,
Some people use a bucket, others pick up and clean all the droppings off a sheet.
We use an aluminium tray and paddle.
Work in bands of about a metre and if there is suction when joining up, splash the surface with a little water.
You should test the suction of the scratch coat first, splash a little water on it and it should remain on the surface for a few minutes, if not, soak the wall first..

Many years ago dashers use to use bakers trays for catching what fell down.

My work is mostly Roughcasting which is simmilar to pebbledashing, like it's been said plenty waterproofer and dampen down scatch prior to hitting the area you have described could easily be fully coated first thus enabling you to save your cast, it's all in the wrist!

Im doing a bit of roughcasting myself this week, repairs to a big house we have started painting, (3 week job) started chopping out the cracks today and revealed a lot of wood rot in lintels so its turned into more than just a cosmetic repair.
Have not done much roughcasting before but i like this sort of thing, matching existing finishes, big formed bellcasts and the roughcasting curves up onto the soffits. i will post photos as job progresses. .

[Jace]

well mr owls i find dashing a peice of piss, same as you might find something a peice of piss and i might not

 

[Dirtybill]

It's only a peice of pish if you know how

 

[theblones]

good tip for dashing is load your dasher up and throw gently bently. You will start getting chippings to stick straight away and evenly, then you can perfect your technique.
I got my technique down ,dont be tickling or nutting

 

[nickelarse]

and wash ur stones first. and throw bently

My mate had some Easterns do a gable for him , i was to busy and they never washed the stones customer aint happy all got to come of.

You can hose the house down that usually does the trick we use noblow in bristol for sparing and that turns the spar dusty after a couple of days but a few hose downs and it sorts it right out other than that the elements will sort it out by weathering.

 

[lucius]

Cheers mate ile tell him to try it first

 

[Dirtybill]

What kind of chips/cast do you guys use which requires washing?

I have never washed any chip that i have used, ever!

What mixes do you normally use bod with the noblow, not done any sparring since i was 18 and can't remember the mix ratios with this stuff...

I've never washed stones before dashing, it's the worst thing ever to try dashing with wet stones, and god knows how long it would take to dry 'em all out before you could use them.
I have used limestone chippings on some walls and hosed them down a few days after.:RpS_thumbup:

 

[owls]

if you get them from derbyshire agg they come prewashed.
