Wood edging a quartz countertop

Zach Nelson Member

I have a client requesting an island top that is quartz with a 12" wood band around the perimeter. I have attached a picture of a top she likes.

I'm trying to figure out the best way to mate the two surfaces to mitigate as many issues as I can with movement of the wood and lack of movement of the quartz.

Would MDF veneer be a better choice than solid wood as it is more dimensionally stable?

Is mechanical fastening or gluing the best route?

Thanks for any input

I wouldn't mate them. I'd just drop the quarts into the hole of the frame.

I did this by simply inlaying the quartz worked well

Dropping into a hole is fine, as long as the opening is fixed. Miters, as shown, are one way to provide a fixed size, correct?

But, how do you keep 12 of miter tight over the days, or weeks ahead where it will move? Ever seen a real miter 12 that was tight and more than a year old?

I see that as your real problem, shy of not knowing the opening will be fixed in your illustrated application.

So, how do you overcome the miter problem?

Veneered substrate will solve that. Not sure if your client will go for it though. I agree, a 12" miter will be tough to keep together over time. Mortise and tenon with no glue and wood pins from the bottom side would allow things to move and prevent splits from forming.

This was recently discussed in the custom furniture forum

1/8 shop sawn veneers over 1 thick suitable substrate has worked for me many times. Make sure to veneer both sides. See if you can hide the edge of the veneer with a profiled edge on the top.

That's a kitchen countertop. Thin veneer could easily get damaged. I would go with the 1/8" shop made thick veneer. Glue the thing up properly with epoxy/splines. Seal the bottom with a coat of epoxy(do not thin it) as well.

I would not use mdf as the substrate. Moisture resistant particleboard would be my choice. Just like a laminate countertop.

I would also fill the gap between the stone and wood with a polyurethane sealant. Water will get spilled across that countertop and find its way between the two materials.

Sikaflex 291 poly adhesive/sealant would be my choice. It comes in black as well as white. This stuff has become the standard on boats for most deck adhesive/sealing.

That looks like a fun project.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
