Epoxy Stone Overlay – How Much Material Do I need

April 27, 2010

Q: How Much Epoxy.com Product #17 Do I need?

I am interested in your Epoxy  Product #17 – www.epoxy.com/17.htm – to overlay a patio and walkway.  I live in Michigan – is there a dealer or will you ship to Michigan?  My patio of 600 sq. ft. – how much epoxy #17 is required? 

You did not say what size stone you are using or how deep you are looking to install it at.

Each stone will take a different amount of resin to bond it in place, depending on the size, shape and how clean it is.  Also each stone size will have a different yield.  But here is how it is calculated (to a theoretical area and coverage).

The recommended starting point is 1.5 gallons of resin plus or minus to each 150 lbs of stone.

I measured a stone that I had that was 1/8 x 1/16,  and got about 0.6 cubic feet per 50 lbs.

So a yield of 3 gallons of #17 and 300 lbs of stone would produce about 0.6x 6 bags or 3.6 cubic feet.

600 square feet at ½ inch thick is (144/2)x600 or 43,200 cubic inches or 25 cubic feet (43,200/1728)

25 cubic feet /3.6 = 6.9 units

The unit size is 3 gallons or ( 7×3)  21 gallons.
