Sealer composition for wood, concrete, porous materials

A C.sub.4 linear polymer water-based wax-free stable emulsion composition used as a sealer for wood, concrete, porous materials first prepared as a stable gel wherein said gel has a viscosity of less than about 5000 centipoise at room temperature from a non-hydrogenated liquid homopolymer selected from the group consisting of polybutene and polyisobutylene with a number average molecular weight of from about 300 to about 10,000, a gel-forming metal soap of a carboxylic acid of from about 12 to about 20 carbon atoms, an amine to reduce the viscosity of said gel selected from the group consisting of triethylamine, triethanolamine and morpholine, a hydrocarbon solvent, an emulsifier which is optionally a nonionic emulsifier, a cationic emulsifier, an anionic emulsifier and mixtures thereof, and an emulsifying-stablizing agent consisting of an acrylic acid copolymer crosslinked with a polyalkenyl polyether wherein said liquid homopolymer is present in an amount of less than 10 wt. percent, said metal soap is present in an amount of from about 1 wt % to 5 wt %, said amine in an amount of from about 0.1 wt. % to 2.0 wt. %, said emulsifier in an amount of from about 0.5 wt. % to about 5 wt. %, said emulsifying-stabilizing agent is present in an amount of from about 0.02 wt. % to about 2.0 wt. %, and said hydrocarbon solvent is present in an amount less than about 35 weight percent of the emulsion composition, wherein said amounts are in percentages of the weight of the water emulsion wherein pH of said emulsion composition is within the range of from about 7 to about 10.
