Hello everyone,

Our precast concrete slab is used as a roof covering for the terrace outdoors. I would like to fill the joints and then paint the entire ceiling. Indoors, this was done with a gypsum-based filler and joint compound. However, at least the gypsum filler is only approved for interior use.

Which materials are best to use here for outdoor conditions? What type of paint would be suitable, exterior paint?

Should I incorporate fiberglass tape?
