Plywood Substrate For Granite Under Table Top

In general should i be putting in 5 8 or 3 4 plywood on top of these cabinets to receive slab.

Plywood substrate for granite under table top.

Neil thackery allendale mich. Many won t stand behind them anyway due to its nature. Quartz table tops are designed for indoor use. That would take something much more substantial and rigid such as the vertical.

I am helping my sister install her 3 4 quartz countertop this week. Finished installing cabinets for my kitchen and getting ready to call a vendor to take measurements for granite slab. I have a granite remnant left over from a kitchen remodel and want to use it as a top for a coffee table. The type and thickness of plywood you use depend on the weight and type of the finish material.

Sides and top are 3 8 thick quartz. Do you think i will need more support under the mdf substrate to keep the 500 pound granite table top from cracking. In your experience how long does it take for the smell of cdx fir to go away. Granite table tops can be used both indoor and outdoors.

The cabinets are job built currently nothing on top of them. I ve seen several overhangs snap from not so hard hits. You can use a variety of types of products as finish materials when building counter tops ranging from granite slabs and tiles to butcher block wood ceramic tile and marble tiles. 3cm granite does not need underlayment.

The weight of the granite will keep the table top in place but if you prefer you may attach it directly to the table frame. I bought 5 8 cdx for the counter to sit on. On top of that will be a 60 inch diameter sheet of mdf 3 4 inch which will serve as the substrate to glue a 72 inch diameter granite table top 1 1 4 inch thick. Quartz table tops are about five times stronger than granite table tops and require zero maintenance outside of daily cleaning.

I also plan on setting a stainless steel undermount sink. Use a power drill with a masonry bit to predrill holes through the plywood on the table frame into the underside of the granite. So you might use a plywood substrate to help replicate a thicker top or to reinforce poorly built cabinets or to help maintain position by adhering the stone to it or for other practical reasons but you don t do it to support stiffen or strengthen the stone. Granite companies will not stand by a top not correctly supported.

Any advice would be appreciated on this. She is complaining about the smell of the cdx and that she would like to use something without added formaldehyde because that s what all her cabinets are. Drive masonry screws through these holes into the granite to secure it. How do i attach the slab to my table assembly.

Their plywood core helps reduce the weight of the top significantly. What would you guys reccomend. I m guessing drilling into the granite is not an option. I m not sure if it needs it or not.
