Install Siding over stucco?

Hi-

We have stucco and are considering siding over. Haven't decided yet on Hardi board or vinyl, so any recommendations there is appreciated. Our main questions is, can we install siding over stucco or will it require special prep work? Thanks!!!

Re: Install Siding over stucco?

i highly recommend not simply going over the old exterior finish, as this can hide any problems with the exterior of the house pertaining to leaks or rot

the issue with stucco is that its harder to go over anyway, as you have to know what its substrate is, some stucco gets installed over a layer of foam then chicken wire, some buildings just get the chicken wire. this being said it has to be known so that the proper method of installing a correct rain screen for harti. also a major thing is that tyvek or typar cannot be installed in contact with stucco, the stucco eats tyvek leaving it useless in turn a non water proof exterior

so my suggestion, strip off the exterior install new cap flashings on all windows and doors, then install 1" rigid foam, if going with harti install rain screen, if vinyl simply start the vinyl after foaming the house... now mind you you dont need the foam but it will help your heating and cooling bill a fair amount
