Parging


I had a new garage installed and the contractor used temeco Polystyrene Insulation over the concrete blocks instead of parging with cement. He then put a thin coating of concrete over this insulation but it cracked and is coming off. What kind of concrete will hold to this insulation? I tried to put some on but it slide right off w/o sticking no mater how thick or thin I make it.

You're not likely gonna have any parge mix stick to it unfortunately. You could go to the effort of using stucco lathe (thin mesh) and that would be yer best bet to make 'er stick. I hate to be a downer but that's not gonna give ya much waterproofing/resistance even if it does stick. disbelief If that's the goal you need to use a membrane...Superseal makes good stuff and is available at most suppliers. Yer gonna wanna cover that up fer cosmetic reasons if there's much exposed. I have a decorative mix that can be sprayed and/or trowelled for cosmetic applications. It would stick as yer wantin' the parge to also but I assumed that you wanted some protection as well as cosmetic?

Right now It's more of a cosmetic look I'm looking for. I waterproof everything from the inside and even with large rain storms and heavy snow melts, it's held up pretty good.

Well, for a DIY cosmetic project, your best bet is to use the stucco lathe and any ol' parge mix should hold. It's not that much work...what kind of area are you needin' to cover? hmm
