Abstract

A drying type joint compound composition is provided, including: at least one binder, a filler and water, the water having a weight percentage in the range of 12-18% of the total weight of the composition.

First claim

What is claimed is:

1. A drying type joint compound composition concentrate, formulated for reduced shipping weight and said concentrate also being formulated for sufficient additional water being added by the user to said concentrate on the jobsite to create a usable joint compound, comprising: at least one binder, a filler having a weight percentage in the range of about 65-85%, and water, said water having a weight percentage in the range of 12-18% of the total weight of the composition, provided that the total liquid component of said concentrate is in the range about 14-20% of the total weight of the composition, and upon formulation approximately 75-95% of said composition passes through a #4 sieve for enhancing mixing of said concentrate with the additional water on the jobsite by the user as desired for creating a usable joint compound forming a mud-like spreadable material which can be applied to the wall surface.

2. The composition of claim 1 , further including at least one thickener.

3. The composition of claim 2 , wherein said at least one thickener is a cellulosic thickener.

4. The composition of claim 2 , further including at least one preservative and at least one suspending agent.

5. The composition of claim 1 , further including magnesium hydroxide for maintaining pH levels at approximately 9.

6. A drying type joint compound composition concentrate, comprising: at least one binder, a filler having a weight percentage in the range of about 65-85%, and water, said water having a weight percentage in the range of 12-18% of the total weight of the composition, said filler and water being present in a ratio of at least 4:1, provided that the total liquid component of said concentrate being in the range about 14-20% of the total weight of the composition and upon formulation approximately 75-95% of said composition passes through a #4 sieve, for enhanced on jobsite mixing, said concentrate composition is formulated such that in use on a jobsite additional water is added to said concentrate post formulation as desired by the user for creating an operational joint compound on the jobsite by the user, the compound having a viscosity of approximately 450 Brabender Units.

7. The composition of claim 1 wherein upon formulation, said concentrate has a moist, granular consistency.

8. The composition of claim 6 wherein upon formulation, said concentrate has a moist, granular consistency.
