Will Kerdi fix adhere over dried Kerdi fix?

[Jason Kay]

So I did a sloppy job on the tub surround with the Kerdi fix. I was thinking to redo a band of Kerdi band over the what I’ve already done. Will the Kerdi fix adhere to what I’ve already done? I want to redo the entire tub surround. Thanks.

It should bond to itself, but you may want to just call Schluter to confirm. Smooth it out to help avoid voids and make a nice filet next time. Practice helps.

FWIW, KerdiFix doesn't 'dry'...it cures - it's a chemical process, not a desiccating one. It cures at about 1/8" per day
