Abstract

Engineered stone, and methods of manufacturing same. An engineered stone comprises: a surface of the engineered stone, wherein the surface comprises one or more pores; and a sealant mixture including a sealant material and a functional component, wherein the functional component modifies one or more properties of said engineered stone.

Claims (17)

1. An engineered stone comprising:

a compacted and cured composite stone material comprising about 85-95% by weight natural quartz aggregates and about 5-15% by weight polymer resins, which forms an entirety of the engineered stone, such that the composite stone material forms both (i) a top surface of the engineered stone and (ii) an entire height of the engineered stone;

wherein said top surface has surface pores therein that are spaced apart by said composite stone material, wherein said surface pores have different sizes;

wherein only said surface pores are filled with a cured and dried functional sealant filling which directly touches said composite stone material;

wherein the functional sealant comprises a functional component which modifies one or more properties of said engineered stone,

wherein said functional component is selected from the group consisting of: an insect repelling agent, an insect eliminating agent, a scent material, an anti-slip material, a dirt repellent agent, a stain repellent agent, an ultraviolet protective agent.

2. The engineered stone of claim 1 , wherein the functional component removes one or more properties of said engineered stone.

3. The engineered stone of claim 1 , wherein said functional sealant comprises a polymeric compound.

4. The engineered stone of claim 1 , wherein said functional sealant comprises wax.

5. The engineered stone of claim 1 , wherein said functional sealant comprises sealant material cured with ultraviolet light.

6. The engineered stone of claim 1 , wherein a top surface of the engineered stone having the pores filled with the sealant is flat.

7. The engineered stone of claim 1 , wherein the pores are filled with at least a heat protective agent.

8. The engineered stone of claim 1 , wherein the pores are filled with at least a fluorescent agent.

9. The engineered stone of claim 1 , wherein the pores are filled with at least a phosphorescent agent.

10. The engineered stone of claim 1 , wherein the pores are filled with at least a surface tension modifier.

11. The engineered stone of claim 1 , wherein the entirety of the engineered stone, including the regions of the engineered stones that surround said pores, are uniformly and exclusively formed of said composite stone material.

12. The engineered stone of claim 1 , wherein said pores comprise pores that are filled with said sealant that was brushed into said pores.
