Mastic turning to toothpaste.

[jackplumb]

Has anyone had problems with mastic turning to a toothpaste like substance? I'm thinking that the sealant was attacked by bleach before it had fully cured. Any ideas?

Had it once before when I bought a load of cheap mastic. Never again!

Was it neutral as opposed to acetoxy?
