Hello Everyone,
I am about to begin tiling in a 2nd floor bi-level home bathroom. A transition from Hardi Backer to sheet rock was taped and spackled using only general purpose spackle. Apparently, that type of spackle is NOT water resistant. I was planning on covering the spackle with an adhesive type grout for tile. Would I be best to crape off the general purpose spackle and replace with a spackle that is water resistant?? The transition between Hardie Backer and sheetrock is located just outside the margins of the jet tub. Am I flirting with disaster if I simply prime the spackle and use the adhesive over it to lay border tile?
Thanks,
Geoman9

No sir, it's done all the time. You will be fine.
If there was any possible trouble, it would be at the tub deck-and that would be one heck of a jetted party to continually wet that area.
Sigh of Relief
Thanks for responding Calvin!

you bet Jerry.
I would have applied durabond across the seam. I also would have feathered away from the seam (outside the tub area) with Lightweight 20, so I could get on it sooner.
And if I was at all concerned, I'd have slathered on (neatly) some Redguard (a waterproofing "liquid" ) which would have made any compound impervious.
But, you don't need to buy the 20 lb tub of redguard. If concerned, hit it with primer to seal the compound. You used reg . bucket mud and not topping-there's more adhesive in the regular, it should hold just fine.
I suppose there could be a first time the method didn't work, but I've not experienced it.

Use thinset for that tile.

Hi Paul,
Other than some spray that leaks out from a shower curtain or during cleaning, I would not expect the general purpose dry wall material (to be covered by some border tiles) would be subject to wetter conditions than just high humidity. That being the case, would you agree with Calvin in my situation and move on, or scrape off the general purpose and apply the setting type to be on the safe side?
Thanks for your responding to my post.
Jerry.
