A method for coating a porous fabric having multiple intersecting fibers that define a web having air-filled interstitial void spaces, comprising 1) applying a curable coating composition at a weight of 1 to 15 g/m 2 to at least one surface of the porous fabric by rolling, brushing, spraying or applying a puddle and scraping the composition into the porous fabric; 2) after step 1), removing air from the interstitial void spaces, and then 3) curing the curable coating composition on the porous fabric to form a porous coated fabric having a cured coating adherent to at least some of the intersecting fibers, wherein the curing is performed in the presence of free radicals and in a low oxygen environment characterized by a partial pressure of oxygen of no greater than 0.1 kPa and/or an atmosphere containing no greater than 0.1 mole percent oxygen until the conversion of monomer(s) is at least 50 mole-percent, wherein the coated substrate is maintained in a low oxygen environment from the time the interstitial air is removed until the conversion of monomer(s) is at least 50 mole-percent, wherein the curable coating composition comprises a) at least one free-radical-curable monomer having exactly one polymerizable group per molecule, the free-radical-curable monomer having at least one hydrocarbyl group that has at least eight carbon atoms bonded directly or indirectly to the polymerizable group, wherein the hydrocarbyl group may be nonfluorinated, partially fluorinated or perfluorinated, the free-radical-curable monomer having a boiling temperature equal to or greater than 100°C, and b) at least one crosslinking monomer having at least two free-radical-curable polymerizable groups and a boiling temperature equal to or greater than 100°C; wherein the coating composition at 22°C is a liquid or a suspension of one or more solids in a liquid phase and the coating composition contains no more than 10% by weight of organic compounds that have boiling temperatures below 100°C and no more than 5% by weight water and further wherein i) step 3) includes a step of contacting the coated fabric with an atmospheric pressure plasma to initiate polymerization of the at least one polymerizable monomer of the curable coating composition and/or ii) the curable coating composition includes a heat activated free radical initiator and step 3) includes heating the coated fabric to an elevated temperature for a time sufficient to decompose at least 50 mole-percent of the free radical initiator to form free radicals. 1) applying a curable coating composition at a weight of 1 to 15 g/m 2 to at least one surface of the porous fabric by rolling, brushing, spraying or applying a puddle and scraping the composition into the porous fabric; 2) after step 1), removing air from the interstitial void spaces, and then 3) curing the curable coating composition on the porous fabric to form a porous coated fabric having a cured coating adherent to at least some of the intersecting fibers, wherein the curing is performed in the presence of free radicals and in a low oxygen environment characterized by a partial pressure of oxygen of no greater than 0.1 kPa and/or an atmosphere containing no greater than 0.1 mole percent oxygen until the conversion of monomer(s) is at least 50 mole-percent, a) at least one free-radical-curable monomer having exactly one polymerizable group per molecule, the free-radical-curable monomer having at least one hydrocarbyl group that has at least eight carbon atoms bonded directly or indirectly to the polymerizable group, wherein the hydrocarbyl group may be nonfluorinated, partially fluorinated or perfluorinated, the free-radical-curable monomer having a boiling temperature equal to or greater than 100°C, and b) at least one crosslinking monomer having at least two free-radical-curable polymerizable groups and a boiling temperature equal to or greater than 100°C; <EOS>
