Abstract
A composition for use as a construction compound is disclosed. The composition may include an inorganic particulate material treated with at least one surface treatment. The surface treatment may include at least one of a fatty acid, a salt thereof, or an ester thereof, silicone oil, silane, or siloxane. The construction compound may improve the workability and/or surface finish of a construction compound. Methods are also provided, including a method for improving the efficiency of application of a construction compound to a drywall joint.
Claims28
A construction composition comprising:
- a first inorganic particulate material;
- a second inorganic particulate material;
- and
- a base material,
- wherein the first inorganic particulate material has received a hydrophobic treatment, and
- wherein the first inorganic particulate material has a d50 smaller than the d50 of the second inorganic particulate, such that the first inorganic particulate material is dispersed among the second inorganic particulate material.

A construction compound having improved workability and/or surface finish, comprising:
- an inorganic particulate material treated with at least one of a fatty acid, a salt thereof, or an ester thereof, silicone oil, silane, or siloxane;
- and
- an untreated inorganic particulate material,
- wherein the treated inorganic particulate material has a d50 smaller than the d50 of the untreated inorganic particulate, such that the treated inorganic particulate material is dispersed among the untreated inorganic particulate material.
A method of improving the workability and/or surface finish of a construction compound comprising,
- providing an inorganic particulate material treated with at least one of a fatty acid, a salt thereof, or an ester thereof, silicone oil, silane, or siloxane and untreated inorganic particulate material in the construction compound,
- wherein the treated inorganic particulate material has a d50 smaller than the d50 of the untreated inorganic particulate, such that the treated inorganic particulate material is dispersed among the untreated inorganic particulate material.
(canceled)
A method of improving the efficiency of application of a construction compound to a drywall joint, the method comprising:
- providing a hydrophobic inorganic particulate material and an untreated inorganic particulate material;
- and
- applying the construction compound in fewer coats as compared to a construction compound devoid of the hydrophobic inorganic particulate material.
