Plywood Substrate For Granite Under Table Top

I m not sure if it needs it or not.

Plywood substrate for granite under table top.

So the reason it doesn t sound like he s going to put decking underneath the granite. How do i attach the slab to my table assembly. 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. 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.

The type and thickness of plywood you use depend on the weight and type of the finish material. Drive masonry screws through these holes into the granite to secure it. Many won t stand behind them anyway due to its nature. In general should i be putting in 5 8 or 3 4 plywood on top of these cabinets to receive slab.

Quartz table tops are about five times stronger than granite table tops and require zero maintenance outside of daily cleaning. Granite companies will not stand by a top not correctly supported. I am helping my sister install her 3 4 quartz countertop this week. Their plywood core helps reduce the weight of the top significantly.

Granite table tops can be used both indoor and outdoors. Quartz table tops are designed for indoor use. In your experience how long does it take for the smell of cdx fir to go away. Sides and top are 3 8 thick quartz.

What would you guys reccomend. Any advice would be appreciated on this. However i highly recommend support for overhangs over 9 because while granite is hard and strong to a point it is brittle. That would take something much more substantial and rigid such as the vertical.

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. I have a granite remnant left over from a kitchen remodel and want to use it as a top for a coffee table. The cabinets are job built currently nothing on top of them. I m guessing drilling into the granite is not an option.

I bought 5 8 cdx for the counter to sit on. Use a power drill with a masonry bit to predrill holes through the plywood on the table frame into the underside of the granite. Do you think i will need more support under the mdf substrate to keep the 500 pound granite table top from cracking. Neil thackery allendale mich.

I ve seen several overhangs snap from not so hard hits. Finished installing cabinets for my kitchen and getting ready to call a vendor to take measurements for granite slab. 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. 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.
