Table 1.0: Composition of all-in-one putty paint composition and preferred % ranges.

The solvent used to dilute the all-in-one putty paint composition is preferably water and the percentage range of this may arbitrarily be determined depending on properties thereof as well as kinds and amounts of consistency required. The pigment which is preferred to be incorporated at a percentage range of 0.5 to 7.0 preferably includes titanium dioxide. The fillers used in the all-in-one putty paint composition include but not limited to kaolin, talc, or calcite. The particle size of fillers is 500 mesh or more. The type and range of fillers incorporated in the present invention depends on the physical properties such as color, opacity or texture, or simply to make the paint handle better.

In accordance with the invention, and also shown in Table 1.0, preferred amount which is used for the present composition comprises, by weight, 13 kg solvent (water), 0.2 kg wetting agent , 0.4 kg cellulosic thickener, 0.3 kg dispersing agent, 0.2 kg emulsifying agent, 0.3 kg in can preservative, 0.15 kg defoamer, 3.0 kg pigment (titanium dioxide), 8 kg china clay, 0.3 kg porbundar whiting, 10 kg talc, 35 kg calcite, 0.2 kg ammonia, 0.9 kg freeze thaw agent, 12 kg binder, 0.9 acrylic thickener, 0.3 kg pine oil, 0.35 coalescing agent and 3.0 kg opaque polymer.

Now, referring to FIG. l, which illustrates a flow chart depicting a method 100 for preparation of all-in-one putty paint composition. In an embodiment of the present invention, the all-in- one putty paint composition can be used as primer, putty or paint, and their combinations. The method 100 starts at step 102 involving mixing of cellulosic thickener and solvent. At step 104, ingredients such as wetting agent, dispersing agent, emulsifying agent, in can preservative, defoamer, and pigment are added to the above mentioned solution and grounded in high speed stirrer for few minutes.

At step 106, the mixture prepared at step 104 is then transferred to pug mixture for better grinding and mixing, to get fine and smooth mixture. At step 108, fillers and freeze thaw agent are added to the fine and smooth mixture and is stirred at high speed to grind all materials. In an embodiment of the invention, fillers used in the putty paint composition presented in table 1.0 are, but not limited to kaolin, talc and calcite. The particle size of fillers is 500 mesh or more. The type and range of fillers incorporated in the present invention depends on the physical properties such as, color, opacity or texture, or simply to make the paint handle better.

At step 110, the above prepared mixture is allowed to cool completely, to get a better base mixture for next step. At step 112, remaining ingredients such as acrylic binder, acrylic thickener, pine oil, coalescing agent and opaque polymer are added under slow stirring preferably for 10-15 minutes.

Finally, at step 114, the resulting mixture from step 112, having paste like consistency, is cooled completely before packaging. The pH range during entire said method is 8.5- 9 and the same is controlled using a basic pH controller.

The all-in-one putty paint composition obtained as above has a paste like consistency and is such that only one coat of it makes it possible to form a film having a thickness of several millimeters or more. Coating of the above putty paint composition may be carried out by spatula-application method, or using a roller or brush, or by a method of controlling a coating viscosity for a spray coating. The disclosed invention is an all in one product; it can be utilized as primer, putty or paint. In another embodiment of the present invention, the method for painting of substrate surface is described.

A user can use this all-in-one putty paint composition as a primer by preferably applying one coat on substrate surface in the thinning ration of 1 : 1 with water. This should be allowed 4-6 hours for effective results.

In another embodiment of the present invention, this all-in-one putty paint composition can be used as Putty. For this, preferably two coats of the all-in-one putty paint composition can be applied to eliminate undulations of the wall. It can be diluted with water, if required. It is generally dried for 4-6 hours for good results.

In yet another embodiment of the present invention, this all-in-one putty paint composition can be used as paint. For this application, one coat of all-in-one putty paint composition can be applied using a roller or a brush. This all-in-one putty paint composition can be used as a final paint coat with a thinning ratio of 1 :0.5 with water. Use of this all-in-one putty paint composition reduces 2-3 coats of application during the painting job. Hence it minimizes time, labor and material required which ultimately reduces the total cost of the painting.
