Cleaning and waterproofing composition

A cleaning and waterproofing composition, comprising:

• (a) from about 1.5 to about 4.5 parts by weight of a siloxane resin selected from the group consisting of a silanol-functional copolymer consisting essentially of SiO.sub.2 units and (CH.sub.3).sub.3 SiO.sub.1/2 units in a molar ratio ranging from 1:0.4 to 1:1.2 and a trimethysilyl-capped copolymer consisting essentially of SiO.sub.2 units and (CH.sub.3).sub.3 SiO.sub.1/2 units in a molar ratio ranging from 1:0.4 to 1:1.2;
• (b) from about 1.5 to about 4.5 parts by weight of a polydimethylsiloxane fluid having a viscosity from 5 to 100,000 cS at 25.degree. C.;
• (c) from about 1.0 to about 3.0 parts by weight of a titanate ester represented by the formula
• Ti(OR).sub.4
• wherein R is independently selected from alkyl radicals having 3 to 8 carbon atoms;
• (d) from about 0.5 to about 3.0 parts by weight of a polydimethylsiloxane-polyoxyalkylene block copolymer wherein said polydimethylsiloxane block has a molecular weight from 10,000 to 50,000, said polyoxyalkylene block is a copolymer of ethylene oxide units and propylene oxide units wherein the polypropylene content is between 0 and 50% on a molar basis, and wherein the weight ratio of said polydimethylsiloxane block to said polyoxyalkylene block is between 2 and 8;
• (e) up to about 95.5 parts by weight of at least one cyclic-dimethyl siloxane selected from the group consisting of octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane and dodecamethylcyclohexasiloxane;
• and
• (f) up to about 95.5 parts by weight of at least one solvent selected from the group consisting of petroleum hydrocarbons, chlorinated hydrocarbons and aromatic hydrocarbons, said solvent being present in such amount that the sum of components (a) through (f) in the composition is 100 parts.
