## Abstract

A solvent mixture of a petroleum distillate and toluene is disclosed. The solvent is used to dissolve a hydrocarbon resin and block copolymers of styrene and isoprene or styrene and butadiene and the solution is applied to newly constructed basement walls to provide a water-resistant elastomeric coating on the walls.

## Claims

### Claim 1

An article of manufacture, comprising a concrete foundation having an interior surface and an exterior surface, and a continuous water impervious elastomeric coating disposed on said exterior surface, said coating consisting essentially of a mixture of a hydrocarbon resin and a copolymer selected from the group consisting of a polystyrene-polyisoprene block copolymer, a polystyrene-polyisoprene-polystyrene block copolymer, a polystyrene-polybutadiene block copolymer, a polystyrene-polybutadiene-polystyrene block copolymer, and mixtures thereof, said coating being produced by adding toluene and an aliphatic petroleum distillate as solvents to said moisture to provide a homogeneous solution having a viscosity in the range of bout 3,000 to 5,000 cps at 70.degree. F., spraying said solution on said exterior surface of the concrete foundation, and thereafter evaporating the solvents.

### Claim 2 (depends on 1)

The article of claim 1, further including a protective sheet material applied to said coating on the exterior surface of said wall to protect said coating against rupture.

### Claim 3 (depends on 1)

The article of claim 1, wherein said hydrocarbon resin is a terpene resin.

### Claim 4 (depends on 1)

The article of claim 1, wherein the petroleum distillate is a mixture of paraffinic and cycloparaffin hydrocarbons and has a boiling point in the rang of about 190.degree. F. to 230.degree. F. and an evaporation rate of about 2.5 to 2.6, said distillate comprising from about 80% to 95% by weight of the combined weight of said distillate and said toluene.
