3 season sun room condensation and flooring remedies
I have 2 3Season -3 glass-sided sunrooms; one on the 2nd story deck and the other on the ground floor
They were both placed on treated plywood on preserved wood stringers, supported by steel framework. .
After 10 years both plywood floors and stringers had rotted out from condensation in the winter.
We replaced the stringers and treated plywood; then coated the floors with fibreglass cloth and resin.
I drilled 2 inch holes every two feet at the edge of the platforms, which has allowed the winter condensation to run out
This has worked very well for over 10 years. I would like to cover the floors with a tile, (ceramic, vinyl, slate, etc) for decorative
reasons. I want to know how I would attach the tile to the fibreglass flooring, bearing in mind that there might be
1. slight flex in the floor, and
2 temperature ranges from -40 to + 100 inside the sunrooms. We are away summer and winter for months at a time, with
all power disconnected, so ventilation fans would not be working.
Maybe the smartest solution would be to repaint the fibreglass flooring and forget about new flooring covering. Any ideas??
