## Abstract

A composition is disclosed for spackeling or joint compound or as a stucco composition including hollow silica particles. Also, disclosed is a preferred composition comprising the following components in the indicated proportions: from about 3 to about 7 parts by weight of latex binder, from about 0.3 to about 1.5 parts by weight of water retention agent, from about 25 to about 36 parts by weight of filler, and from about 1 to about 5 parts by weight of hollow silica particles, said hollow silica particles having an average diameter of from about 25 microns to about 100 microns and a density of from about 0.10 g/cc to about 0.20 g/cc.

## Claims

### Claim 1

An non-leveling asbestos-free joint compound or stucco composition comprising the following components in the indicated proportions: from about 3 to about 7 parts by weight of binder selected from the group consisting of latex binder and polyvinyl alcohol; from about 0.3 to about 1.5 parts by weight of water retention agent; from about 25 to about 36 parts by weight of filler selected from the group consisting of calcium carbonate, calcium sulfate, mica, talc, sericite and mixtures thereof; and from about 1 to about 5 parts by weight of hollow silica particles, said hollow silica particles having an average diameter of from about 25 microns to about 100 microns and a density of from about 0.10 g/cc to about 0.20 g/cc.

### Claim 2 (depends on 1)

An asbestos-free joint compound or stucco composition according to claim 1 comprising the following components in the indicated proportions: from about 4.0 to about 5.5 parts by weight of binder, from about 0.5 to about 1.0 parts by weight of water retention agent, from about 33 to about 36 parts by weight of filler, and from about 3 to about 4.5 parts by weight of said hollow silica particles.

### Claim 3 (depends on 1, 2)

A joint compound or stucco composition according to claim 1 or 2, wherein said silica particles have an average diameter of from about 35 microns to about 65 microns and a density of from about 0.12 g/cc to about 0.18 g/cc.

### Claim 4 (depends on 1, 2)

A joint compound or stucco composition according to claim 1 or 2, further comprising from about 30 to about 55 parts by weight of water in combination with about 70 to about 45 parts by weight of said composition.

### Claim 5 (depends on 1, 2)

A joint compound or stucco composition according to claim 1 or 2, further comprising from about 2 to about 6 parts by weight of attapulgus clay.

### Claim 6 (depends on 1, 2)

A joint compound or stucco composition according to claim 1 or 2, further comprising from about 0.5 to about 5 parts by weight of montmorillonite clay.

### Claim 7 (depends on 1, 2)

A joint compound or stucco composition according to claim 1 or 2, wherein said binder is polyvinyl alcohol.

### Claim 8 (depends on 1, 2)

A joint compound or stucco composition according to claim 1 or 2, wherein said water retention agent is sodium carboxymethyl cellulose.

### Claim 9

A method for spackeling or stuccoing a wall or ceiling comprising applying to said wall or ceiling a non-leveling asbestos-free composition comprising the following components in the indicated proportions: from about 3 to 7 parts by weight of binder selected from the group consisting of latex binder and polyvinyl alcohol; from about 0.3 to about 1.5 parts by weight of water retention agent; from about 25 to about 36 parts by weight of filler selected from the group consisting of calcium carbonate, calcium sulfate, mica, talc, sericite, and mixtures thereof; from about 1 to about 5 parts by weight of hollow silica particles, said hollow silica particles having an average diameter of from about 25 microns to about 100 microns and a density of from about 0.10 g/cc to about 0.20 g/cc; and from about 30 to about 55 parts by weight water.
