The manufacturer recomends a circular saw (Skill Saw) with a blade specificaly made for Hardie Board. Diablo makes ones for a 7 1/4 saw, and it is sold at homeDepot. https://www.homedepot.com/p/DIABLO-7-1-4-in-x-4-Teeth-Polycrystalline-Diamond-PCD-Tipped-James-Hardie-Fiber-Cement-Saw-Blade-D0704DH/100627137 or better a miter saw with a blade for hardie board. Here is an example of a 12 inch. https://www.homedepot.com/p/DIABLO-12-in-x-8-Tooth-Polycrystalline-Diamond-PCD-Tipped-James-Hardie-Fiber-Cement-Cutting-Saw-Blade-D1208DH/203162564
By my calculations, assuming 1.25 inch overlap (7 inches exposed) it works out to 7 sq ft coverage per plank. 1700 sq ft / 7 = 243 planks 10 % loss would add another 24 for a total of 267.
I would say no. I solid stain might work, but I don't recall any mention of staining in the literature.
I bought blue but would like to edge it in a different coor what are my options
Hardie recommends flashing under each vertical joint with no caulk.
Ummm... I suppose you could... It is typically installed as a shiplap installation, with the boards running horizontally, and each board overlapping the one below by about 1 to 1-1/2 inches. That way when water strikes the surface, each board sheds the water OUT and DOWN. This gives you a weather tight shell on your building. If you run the boards vertically, the joints will catch and channel the water along the joint and into the building. Even with the best caulking job (and this would a long tedious caulking job), you will never get a water tight seal. Not good.
What neither of these answers tell you is they've assumed I think 8" plank - 1 1/4" in overlap = 6 3/4" net exposure per plank, multiplied by 12' lengths = 6 3/4 sq ft per plank# Thus 2600 SF divide 6#75 = 385 planks and add some for waste, maybe 5%# So it REALLY depends on plank size what you like to see or what fits in your neighborhood/region# For my detached garage in KC, I used 8 1/4 plank, thus 7" of exposure# This is 40% more exposure than the 6 1/4 plank, 5" exposure, and for only about $1 more per plank, much more cost effective# In this same example, 2600 sf divide 7 sq ft exposure = 371 planks - that's 20 fewer at at about $9+ per plank, that's almost $180 difference - not a lot of $ but something to consider.
Sorry, the formula is square footage you need to cover divided by exposure of plank. So 744 divided by 7 equals 107 pieces
Yes they can as long as you have a saw big enough to cut all the way through it or slide through it.
