securing firmly a laminate to the recreational court and also to exposed crack filling material to cover the crack, wherein the laminate comprises an adhesive applied to a flexible fabric material, and wherein the laminate is secured to the recreational surface and the exposed crack filling material by use of the adhesive applied to the flexible fabric material, and

securing a fabric to both the laminate and to the recreational court using an adhesive material wherein the flexible crack filling material is a polyurethane foam.

2. The method of claim 1 , wherein the crack filling material comprises a flexible sealant material.

3. The method of claim 1 , wherein the laminate comprises a flexible fabric covered with a rubberized, asphaltic adhesive material.

4. The method of claim 1 , wherein the adhesive used to secure at least the edges of the fabric to the laminate comprises an acrylic or latex adhesive.

5. The method of claim 1 , wherein the fabric secured to the laminate comprises a flexible polyester fabric.

6. The method of claim 1 , wherein the flexible, waterproof polyester foam substantially seals the inner edges of the crack.

7. The method of claim 1 , wherein the laminate, prior to application to the surface, further comprises a paper release backing secured to the waterproof adhesive portion.

8. The method of claim 1 , further comprises coating exposed laminate and fabric with a paint.

9. The method of claim 8 , wherein the paint comprises an acrylic paint.

10. The method of claim 1 wherein the adhesive of the laminate comprise a waterproof adhesive.

12. A method for repairing a crack in a recreational court or surface comprising

cleaning the crack to remove loose material from within the crack,

filling the crack with a flexible, waterproof sealant material, which adheres to the edges of the crack and accommodates expansion and contraction of said crack,

securing firmly a laminate to the recreational court and also to exposed sealant material to cover the crack, wherein the laminate comprises a waterproof adhesive applied to a flexible fabric material, and wherein the laminate is secured firmly to the recreational court and the exposed sealant material by use of waterproof adhesive applied to the flexible fabric material, and

securing a flexible polyester fabric to both the laminate and to the recreational court using an adhesive material wherein the flexible, waterproof sealant material is a polyurethane foam.

13. The method of claim 12 , wherein the laminate comprises a rubberized, asphaltic, adhesive material secured to the fabric material.

14. The method of claim 12 , wherein the fabric secured to at least the edges of the laminate comprises a flexible polyester fabric.

15. The method of claim 12 , wherein the laminate, prior to application to the surface, further comprises a paper release backing secured to the waterproof adhesive portion.

16. The method of claim 12 , further comprises coating the fabric and exposed portions of the laminate with a paint.

17. A method for repairing a crack in a recreational court or surface comprising

cleaning the crack to remove loose material from within the crack,

filling the crack with a flexible polyurethane foam, which adheres to the edges of the crack,

securing firmly a laminate to the recreational surface and also to the exposed polyurethane foam to cover the crack, wherein the laminate comprises a rubberized asphaltic material adhesive secured to a flexible fabric material, and wherein the laminate is secured to the recreational surface and the exposed crack filling material by use of this adhesive applied to the flexible fabric material, and

securing a flexible polyester fabric to both the laminate and to the recreational surface using an adhesive material, and

coating the fabric and exposed laminate with an acrylic paint wherein the flexible, waterproof sealant material is a polyurethane foam.

18. The method of claim 17 wherein the adhesive of the laminate comprise a waterproof adhesive.
