[DominoRemoved]

i got called in on a rendering job last thursday.
To help a mate out as it was a nice sized job now what im struggling to get my head round is the mix he is useing .
Its on concrete blocks didnt even wet it first the mix is 6:1:1 scrach/6:1:1 top coat ???
now we have scrached 98% of it as the scaffold was in the way along with ha fence too.
toped both the frunt and back wetted the scrach coat and layed it on the used a spat too flaten it in didnt even use a straight edge??
its looking really good
BUT what are the come backs of not wetting the blocks first and using the same mix on both coats??
as i have allwase use a weeker mix top coat (how i was talt too)

[S a plastering]

dont wet concrete blocks down either before scratch as luc says very little wp on them blocks there is no suction at all from em

 

[Dirtybill]

Nothing wrong wi that, what kinda sand did you use and what type of sponge?

 

[DominoRemoved]

using plastering sand opc and lime water proofer and feb mix
used a tilers sponge and a jumbo spunge
if the work was there id render all the time love it

 

[s.p.t plastering]

That looks tidy that!....Sand looks like a different colour to i've seen before though

 

[henry]

what do you think would happen if you did the sides all in one day with out leaving the scratch coat what suction, do you have on them blocks.

 

[lucius]

Have done it Henry, there is very little suction on concrete blocks the only prob doing scratch and top same day is that the blockwork joints seem to grin through more.

 

[henry]

Yer that could happen but should dry out if we was doing the internal blocks we would slap it on all in one go.

 

[lucius]

So would i but i generaly lay internal blocks in a garage to face standard and joint them up.

 

[plaster man]

job looks good dont see sand the coulor to often looks nice

 

[henry]

The colour of the sand I think is due to the lime in the mix

 

[lctanner]
