The process of applying a coating to a substrate which comprises; foaming a composition containing from about 50 to about 70 parts by weight of a synthetic resin coating agent; and from about 2 to about 8 parts by weight of an acid type catalyst; from about 5 to about 14 parts by weight of the expansion mixture for foaming coatings which comprises a foamable mixture of: (a) 15 to 53 weight % of a compound having the formulae: R－(OCH2CH2)nOSO3H-M+ and/or R1－(CH2CH2O)n+1SO3H-M+ wherein R is alkyl of 6 to 18 carbon atoms or hydroxyalkyl of 6 to 18 carbon atoms; R1 is hydrogen, alkyl of 6 to 18 carbon atoms or phenoxy substituted with not more than two alkyl groups each having 1 to 23 carbon atoms; n is an integer having a value of 0 to 10; and M is sodium, potassium, calcium, ammonium or an alkyl- or alkyloxy-amine radical of 1 to 6 atoms; (b) 5 to 42 weight % of a compound having the formulae: [Figure] and/or [Figure] wherein R3 is alkyl of 6 to 20 carbon atoms; R4 and R5 are independently alkyl of 1 to 4 carbon atoms; X is sulfate, halide or phosphate; m and m′are integers independently having a value of 4 to 20; and p and p′are integers independently having a value of 0 to 20; and (c) 5 to 45 weight % of a compound having the formula: [Figure] wherein R6 and R7 are independently alkylene of 4 to 22 carbon atoms; r and r′are independently integers each having a value of 0 to 15; w and w′are integers independently having a value of 0 to 1; and y is sodium or potassium; and from about 2 to about 26 parts of diluent per part of coating agent; expanding said mixture up to about 1,000%; contacting the substrate and the resulting foam to provide a layer of foam on said substrate; and drying said foam coated substrate at a temperature between about 175°F. and about 390°F. for a period of from about 30 seconds to about 60 minutes.
