Removing the Old Countertop

There is a good chance you will not be able to simply remove the old countertop and replace it with a new one. The marble tile that was used as the counter surface may have been set into a bed of mortar, or onto some type of adhesive material. In either case, if the countertop has become cracked and damaged, it will remain attached to the cabinet.

Determine Countertop Damage

Since this tutorial steps through removing and reinstalling a countertop, take time now to determine what type of damage has occurred. If necessary, separate the counter from underlayment (the wood substrate beneath). Use care when cutting and prying away sections; avoid gouging the wood. Or you can call where you bought your marble countertop. Natural stones all have the same supplier. Like if you buy marble, they must also be a granite countertops supplier so maybe you can change it or they will help you to fix it. 

Prep Countertop Edges

Once the countertop is detached from underlayment, you can begin to work on removing damaged edges. Start by using a chisel and hammer to chip away at the mortar or adhesive that has been used to secure tiles in place. You can also use an oscillating tool with a diamond cutting blade for this task. Be careful not to damage surrounding tiles when working around their perimeter.

Cut Tiles from Counter Surface

When all other means have failed, it’s time to cut individual tiles free of the counter surface. This should be done by scoring into the grout joints with an oscillating tool fitted with a diamond blade then wiggling the tile back and forth to break it free.

Prepare Countertop and Tile for Installation

Once all the damaged tiles have been removed, you can start preparing your countertop and tile surface for reinstallation. Use a carbide rotary tool bit or diamond blade on an oscillating tool to prepare the mortar bed or adhesive underlayment for installation. This will ensure that proper adhesion can occur during reassembly.

Replace Countertops

Before beginning the process of replacing your old countertops with new ones, be sure you measure accurate dimensions and cut outboards as necessary. You can use a circular saw fitted with a masonry blade to do this task; just take care not to damage surrounding tiles and grout. For added protection, cut out a board larger than the countertop surface area and use it as a shield while sawing. You can also have professionals like marble or granite countertops suppliers so they will help you to replace it easily. Reattach the counter, clean the surface. 

Reattach Countertops to Cabinets

After all the new tiles have been installed in their proper positions, you can reattach your countertops to cabinet bases. Make sure each counter is properly aligned before attaching it by screwing through predrilled holes in top boards into matching pilot holes in cabinets below. Of course, follow manufacturer instructions when doing this for any kitchen appliances that are attached to countertop surfaces.

Seal Countertops

Use a specially formulated grout sealer to protect your newly installed countertops. Apply the sealant according to manufacturer instructions, then allow it time to dry before using new kitchen counters once again. Now you’re ready to prepare meals on your beautiful new marble countertops!
