Recipe for parging

pghdan's picture

Just wanted to know what the recipe was for parging.  This will be going on a rubble


foundation wall  on the interior of a basement.  Would like to mix it up myself so any


help would be appreciated.

you gonna "shoot" it on or trowel...

I was hoping to fling/paint (don't know if there is a better word) it on with a mason's brush. 


This foundation is very uneven so I think it would be difficult to trowel it on.  The underlying  mortar is pretty loose.  So I was planning to brush out the worst with a wet mason's brush and then apply a bonding agent before proceeding.

keep in mind parging is a really thin top coat...


that loose mortar needs to be removed with more than a wet brush...


something tells me you'll have to repoint and then stucco to get where you wanna be...

Thanks IMERC,  I have started to remove some of the loose mortar and to fill in the


bigger voids with new mortar.   The only thing is the old mortar is so deteriorated


that I'm sure I could remove all of it ..... if I really put my mind to it.  At this point it


more resembles loose sand than anything aproximating mortar.

sounds like high lime/sand content vs portland ratios...


use a grouting bag to replace the mortar.. makes life more better....


do small sections as you go...


smaller sections still the closer to the floor ya get...

should have also asked you how dry is the foundation and what do you want the final to look like???

type "N" mortar with a polymer additive.... (bonding agent)...


prime the wall 1st with bonding agent....


limit parging to 1/8" max thickness....


or...


stucco it instead...
