I have about 300 boards that are 12' long of HardiPlank Select Cedar Mill 5 1/4". With a 4” exposure you get 4 sq ft per board so for example 100 boards will cover will cover 400sq ft The material is primed and ready for paint. $4.50 per board (I paid about $6.00 a board at home depot) Location: newport it's NOT ok to contact this poster with services or other commercial interests rhodeisland
