| Rousos adds that a buildup of 40 to 60 mils is very important. |
| The average thickness of FPO in Europe is about 60 mils, and no product sold there is less than 48 mils. |
| The drops have to be small enough to hang in the air instead of immediately falling to the slab surface, which puts them in the range of about 5 mils or smaller. |
| Some sheet metal, particularly that used in the manufacture of steel studs and other steel-framing members, may also be referred to by its thickness in mils. |
| Research has indicated that the optimum thickness for the total paint coat is 4-5 mils or about the thickness of a sheet of newspaper. |
| Many have observed the benefit of using materials with a minimum thickness of 15 mils when ready-mix trucks or laser screeds drive directly on the vapor retarder. |
