Method for undermounting a sink
A method for undermounting a sink to a countertop includes preparing a countertop and a sink. Thereafter a primary channel is routed within the backside of the countertop, the primary channel including a base and being shaped and dimensioned for receipt of the sink flange, and a secondary channel is routed within the base of the primary channel along an interior circumference of the primary channel. Substrate material is then removed from the secondary channel to expose an underside of the decorative laminate and adhesive is applied within the secondary channel so that the underside of the decorative laminate is fully covered. A bead of adhesive is applied to the base of the primary channel and the sink flange is placed within the primary channel. A support plate is secured around the sink flange to provide support and a central portion of the countertop defined by the primary channel is cut out to expose the bowl of the sink.
1. A method for undermounting a sink to a countertop, comprising the following steps:
preparing a countertop including a backside and an upper surface, the countertop being composed of a decorative laminate secured to a substantially rigid substrate;
preparing a sink for installation, the sink including a bowl and an outwardly extending sink flange;
routing a primary channel within the backside of the countertop, the primary channel including a base and being shaped and dimensioned for receipt of the sink flange;
routing a secondary channel within the base of the primary channel along an interior circumference of the primary channel;
removing substrate material from the secondary channel to expose an underside of the decorative laminate;
applying adhesive within the secondary channel so that the underside of the decorative laminate is fully covered;
applying a bead of adhesive to the base of the primary channel;
placing the sink flange within the primary channel;
securing a support plate around the sink flange to provide support; and
cutting out a central portion of the countertop defined by the primary channel to expose the bowl of the sink.
2. The method according to claim 1 , wherein the step of preparing includes ensuring a height of the sink flange is approximately ⅝-inch, or less, and trimming the sink flange to a desired thickness if the height exceeds ⅝-inch.
3. The method according to claim 1 , wherein the step of routing the primary channel includes preparing a template substantially conforming to a sink cut out required for undermounting of the sink to the countertop and fastening the template to the backside of the countertop.
4. The method according to claim 1 , wherein the primary channel has a width of approximately 1⅞-inch to approximately 2⅛-inch and the substrate in the primary channel has a thickness of approximately 3/32-inch to approximately ⅛-inch.
5. The method according to claim 1 , wherein the secondary channel has a width of approximately ¾-inch and the substrate in the secondary channel has a thickness of approximately 1/64-inch.
6. The method according to claim 1 , wherein the step of removing includes cleaning the underside of the decorative laminate.
7. The method according to claim 1 , wherein the adhesive matches the sink color.
8. The method according to claim 1 , wherein the substrate is medium density fiberboard or particleboard.
9. The method according to claim 1 , wherein the decorative laminate is high pressure decorative laminate.
10. An undermounted sink and countertop assembly, manufactured in accordance with the method comprising:
preparing a countertop including a backside and an upper surface, the countertop being composed of a decorative laminate secured to a substantially rigid substrate;
preparing a sink for installation, the sink including a bowl and an outwardly extending sink flange;
routing a primary channel within the backside of the countertop, the primary channel including a base and being shaped and dimensioned for receipt of the sink flange;
routing a secondary channel within the base of the primary channel along an interior circumference of the primary channel;
removing substrate material from the secondary channel to expose an underside of the decorative laminate;
applying adhesive within the secondary channel so that the underside of the decorative laminate is fully covered;
applying a bead of adhesive to the base of the primary channel;
placing the sink flange within the primary channel;
securing a support plate around the sink flange to provide support; and
cutting out a central portion of the countertop defined by the primary channel to expose the bowl of the sink.
11. The method according to claim 10 , wherein the step of preparing includes ensuring a height of the sink flange is approximately ⅝-inch, or less, and trimming the sink flange to a desired thickness if the height exceeds ⅝-inch.
12. The method according to claim 10 , wherein the step of routing the primary channel includes preparing a template substantially conforming to a sink cut out required for undermounting of the sink to the countertop and fastening the template to the backside of the countertop.
13. The method according to claim 10 , wherein the primary channel has a width of approximately 1⅞-inch to approximately 2⅛-inch and the substrate in the primary channel has a thickness of approximately 3/32-inch to approximately ⅛-inch.
14. The method according to claim 10 , wherein the secondary channel has a width of approximately ¾-inch and the substrate in the secondary channel has a thickness of approximately 1/64-inch.
15. The method according to claim 10 , wherein the step of removing includes cleaning the underside of the decorative laminate.
16. The method according to claim 10 , wherein the adhesive matches the sink color.
17. The method according to claim 10 , wherein the substrate is medium density fiberboard or particleboard.
18. The method according to claim 10 , wherein the decorative laminate is high pressure decorative laminate.
