There isn't one “best paint” for every Long Island house.
The better question is:
What coating system is best for this particular surface and exposure?
At Harbor Paints, we regularly work on homes exposed to Long Island's combination of moisture, strong summer sun, freezing winters and coastal conditions.
Benjamin Moore describes AURA Exterior as providing strong color retention and resistance to chalking, UV exposure, fading, rain, snow and wind. Benjamin Moore
Those characteristics make it worth considering for demanding Long Island environments.
We also use and specify other premium systems—including Benjamin Moore Regal Select Exterior—depending upon the substrate. Regal Select's formulation emphasizes adhesion and resistance to fading, cracking and peeling. Benjamin Moore
Suppose your cedar siding is peeling.
Buying a $90 gallon of paint doesn't magically correct:
The coating is only the final part of the system.
The Cedar Shake & Shingle Bureau even specifies Type 316 stainless-steel fasteners within 15 miles of salt water for cedar shake/shingle installations—an indication of just how seriously coastal exposure should be taken. Cedar Shake and Shingle Bureau
Premium paint cannot compensate for poor preparation.
For Harbor Paint, our exterior formula is simple:
Clean → Repair → Scrape → Sand → Prime → Caulk → Paint
Skip the important steps and even an expensive coating can disappoint.
