Question
We're re-siding with fiber cement. The initial paint job is warrantied for 15 years. How long can we expect subsequent paint jobs to last?
We live in CT. We're re-siding with Hardiplank & Hardi Trim. To improve water resistance, windows are being replaced at the same time.
Answer
According to James Hardie, Inc., paint applied to the siding over the original finish has a life expectancy of about seven years. This is as long as you follow their specifications for painting as follows:
- Make sure all caulking joints are sound,
- apply one coat of acrylic latex primer, over spot priming for any damaged surface areas, and
- apply two coats of exterior-rated acrylic latex paint from any one of a number of manufacturers.
