It looks very old what are you rendering it with.

 

[martinemj]

yea its got to be a couple of hundred yrs old (the old part )

using lime render 3 coats

will need a lot of pointing and dubbing out

mix of block ,brick ,stone (most is stone)

had been rendered over pebble dash, so loads to hack off !!!

I wish it was my job better then re skimming for sure what are going to do about the salt in the brickwork.

 

[martinemj]

for lime they recommend not to use a salt Neutralizer

just to brush it off ??

sounds about right... salt neutralizer being acidic, lime being alkali, they'd neutralize each other.. :RpS_blink:

still, cements got lime in it.. then i went for a google for 'gypsum ph' and found this...

Gypsum immediately decreases the pH of sodic soils or near sodic soils from values often over 9 but usually over 8 to values of from 7.5 to 7.8. These values are in the range of acceptability for growth of most crop plants. Probably more than one mechanism is involved. Ca++ reacts with bicarbonate to precipitate CaCO3 and release protons which decrease the pH. Also, the level of exchangeable sodium is decreased which lessens the hydrolysis of clay to form hydroxides. These reactions can decrease the incidence of lime and bicarbonate induced iron deficiency. [SUB](3)[/SUB]

so i havent reaaallly learned anything except maybe its actually good for the garden to dig a little hole and tip your wash out in it... provided its clay soil... :RpS_bored:

needle gun was used on the front as it had limewash /loose stone to face
clean it up nice...

lots of straight joints in stone (additions and changes ) stainless steel eml fixed with s/s screws and washers

about 3 days of dubbing out /extreme pointing
