How Much Area Will A Gallon Of Roof Coating Cover

For example to cover 2000 sq.

How much area will a gallon of roof coating cover.

Square footage is based on multiplying the length of an area x width of that area. Square footage is based on multiplying the length of an area x width of that area. 1 gallon at 10 mils thick will cover 160 sq. One 5 gallon pail covers 250 square feet of roof with 2 coats.

1 gallon at 1 mil thick will cover 1600 sq. 1 gallon at 20 mils thick will cover 80 sq. Any derivative of 1600 based on the thickness of the coating will tell you how many square feet the product yields. 1 gallon at 5 mils thick will cover 320 sq.

What about non rectangular areas. Do not apply in temperatures below freezing above 120 f 49 c or if rain is expected within 2 hours. 22 dry mils applying temperature. Add the 2 areas 100 200 300 sq ft to get a total.

In those instances you need to break the area down into smaller rectangles. For all three products allow one gallon of roof coating for every 80 square feet of corrugated metal roof or 100 square feet of smooth metal roofing. For instance an l shaped surface can be broken into 2 smaller rectangles see illustration below. One gallon will cover 50 square feet of foam or modified bitumen roofing concrete or bonded tar and gravel roofing.

2000 500 4 5 gallon pails. For instance an l shaped surface can be broken into 2 smaller rectangles see illustration below. For two coats double that figure. What about non rectangular areas.

Ft divide by 500 sq ft to equal 1 coat application. In those instances you need to break the area down into smaller rectangles. Highly porous concrete roofs may require more coating for proper coverage.
