If your drum is a 55 gallon drum and your paint can cover 400 square feet per gallon then you may cover (one coat only) a square almost 150 by 150 feet.
A gallon of paint covers about 300 square feet at a usual thickness of one coat; your example of 0.1 cm thick is very thick coat, equivalent to about 6 coats of paint at least; you could cover about 300/6 =50 square feet at that thickness.
If your gloss white is good quality, then a single coat should cover a grey primer.
One coat of paint is a layer of paint applied and allowed to dry. Two coats is double this with proper drying between each coat.
Permanizer is the best one coat paint that is made by PPG Porter Paints.
Applying a second coat of paint is not necessary unless you are still able to see the original paint under the coat you just applied. If you were able to achieve an even, uniform coverage with the first coat then pat yourself on the back and admire your good painting work. Similar colors tend to cover with one coat. Trying to cover a dark shade of paint like brown, green or blue with something much lighter like antique white will invariably require 2 full coats for adequate coverage.
about 4 gallons for one coat for smooth surface; about 6 gallons if the surface is rough
A gallon of paint one coat will cover about 300 square feet; if surface is very smooth about 400 sq ft,and if very rough maybe 150-200 sq feet
One gallon should cover at least 300 square feet for smooth surface, 150 for rough. for one coat.
