Abstract

A process of making a decorative resilient floor covering is disclosed comprising the steps of applying a first layer of a first curable polymeric material to a substrate. A tape is applied to selected regions of the first layer of the first curable polymeric material after the curing thereof. A second layer of a second curable polymeric material is applied to the cured first layer. A pigmented particulate material is applied to one of the first and second layers prior to the curing thereof. The tape is removed to reveal the first layer and the second layer with the pigmented particulate material.

Claims

1. A process of making a decorative resilient floor covering comprising the steps of:

applying a first layer of a first curable resilient polymeric material to a substrate with the resilient polymeric material consisting of a two-part water activated polyurethane;

spraying a first pigmented particulate material in the form of paint chips upwardly to fall by action of gravity onto the first layer of the first curable polymeric material prior to the curing thereof with the first pigmented particulate material having a first color;

applying a tape material in a decorative pattern to selected regions of the first layer of the first curable polymeric material after the curing thereof;

applying a second layer of a second curable polymeric material to the cured first layer;

spraying a second pigmented particulate material in the form of paint chips upwardly to fall by action of gravity onto the second layer of the second curable polymeric material prior to the curing thereof with the second pigmented particulate material having a second color different than the first color of the first pigmented particulate material;

removing the tape material to reveal the first color of the first layer and the second color of the second layer; and

applying a third layer of a third curable polymeric material to the cured second layer and exposed cured first layer.

2. A process of making a decorative resilient floor covering as set forth in claim 1, wherein the substrate is a substantially rigid substrate.

3. A process of making a decorative resilient floor covering as set forth in claim 1, wherein the substrate is a semi-rigid substrate.

4. A process of making a decorative resilient floor covering as set forth in claim 1, including the step of preparing the substrate for adherence by the first curable polymeric material.

5. A process of making a decorative resilient floor covering as set forth in claim 1, wherein the step of applying the first layer of the first curable polymeric material to the substrate includes troweling the first curable polymeric material onto the substrate.

6. A process of making a decorative resilient floor covering as set forth in claim 1, wherein the step of applying the first layer of the first curable polymeric material to the substrate includes applying the first layer of the first curable polymeric material on to the substrate to a thickness between 0.010 and 0.020 inches.

7. A process of making a decorative resilient floor covering as set forth in claim 1, wherein the first pigmented particulate material comprises paint chips in the configuration of flakes having a longitudinal and transverse dimension of 0.05 to 0.25 inches and having a thickness between 0.003 to 0.007 inches.

8. A process of making a decorative resilient floor covering as set forth in claim 1, wherein the step of applying the second layer of the second curable polymeric material to the cured first layer includes rolling the second curable polymeric material onto the first layer by a roller.

9. A process of making a decorative resilient floor covering as set forth in claim 1, wherein the step of applying the second layer of the second curable polymeric material to the first layer includes spraying the second layer of the second curable polymeric material onto the first layer to have a thickness between 0.005 and 0.010 inches.

10. A process of making a decorative resilient floor covering as set forth in claim 1, wherein the second pigmented particulate material comprises paint chips having a longitudinal and transverse dimension of 0.05 to 0.25 inches and having a thickness between 0.003 to 0.007 inches.

11. A process of making a decorative resilient floor covering as set forth in claim 1, wherein the step of applying a third layer of a third curable polymeric material to the cured second layer and exposed cured first layer includes rolling the third curable polymeric material onto the cured second layer and exposed cured first layer.

12. A process of making a decorative resilient floor covering as set forth in claim 1, wherein the step of applying a third layer of a third curable polymeric material to the cured second layer and exposed cured first layer to have a thickness between 0.005 and 0.010 inches.

13. A process of making a decorative resilient floor covering comprising the steps of:

applying a first layer of a first curable resilient polymeric material to a substrate with the resilient polymeric material consisting of a two-part water activated polyurethane to a thickness between 0.010 and 0.020 inches;

spraying a first pigmented particulate material in the form of first paint chips upwardly to fall by action of gravity onto the first layer of the first curable polymeric material prior to the curing thereof with the first pigmented particulate material having a first color;

applying a tape material in a decorative pattern to selected regions of the first layer of the first curable polymeric material after the curing thereof;

rolling a second layer of a second curable polymeric material to the cured first layer to have a thickness between 0.005 and 0.010 inches;

spraying a second pigmented particulate material in the form of second paint chips upwardly to fall by action of gravity onto the second layer of the second curable polymeric material prior to the curing thereof with the second pigmented particulate material having a second color different than the first color of the first pigmented particulate material;

removing the tape material to reveal the first color of the first layer and the second color of the second layer; and

rolling a third layer of a third curable polymeric material to the cured second layer and exposed cured first layer to have a thickness between 0.005 and 0.010 inches.
