... in response to Beach houses/Salt corrosion--questions, posted by Red Clay on Feb 24, 2005As a former long-time resident of the lower Florida Keys, Keys West and Cudjoe Key, I would recommend:
1. On the outside of the house, ie, lights, etc. plastic
locks a high grade brass. Strongly recommend nothing
but stainless steel screws. etc.. Aluminum will pit and is high
maintance. Never allow salt water to be used.
2. Using salt water to mix concrete will cause spalling.
ANY Slight rust stains coming out of an otherwise
innosymptom of spalling. If you see this there are
problems. A bitch to repair and expensive. I had
a porch that had to be removed and replaced.
Spalling is repaired by digging out the cracked
concrete, cutting off rusted steel, priming the
remaining exposed area and then concreting over the
hole.
3. There is not really a paint that is corrosion proof.
It may provide temp. aid but is also high maint.
In shot there are no quick fixes. Good luck
