Tips for installing marble countertops

Before installing marble countertops, remember that marble countertops usually come in sheets, and sometimes a single iron covers the entire surface of a countertop. However, the most common is that two or more marble slabs have to be bonded with epoxy to create the entire marble surface.

Carefully remove existing countertop material and disconnect all gas and plumbing pipes before removing appliances.

Before installing marble countertops visit https://countertops-more.com, make sure all cabinets are level, flush and securely attached to the floor and wall. To avoid too many recesses and wide spaces that require an excess of filling material, make sure that the cabinets are leveled with a difference of less than ⅛ of an inch in a 10-foot section and that the walls have a variation of less than ⅛ of inch against a straight plane (to lead and without excessive curves).

Some marble countertop installations do not require any lower bases: cabinet frames are strong enough to support marble slabs. But, to install marble countertops with protruding edges or many large and open cabinets, you will probably need to rest the countertop on a sheet of contra inch plywood exterior or a ½ inch cement panel installed on the frame of the cabinet and use decorative brackets under the protruding edges to support the weight.

Use Kraft paper or something harder but lighter to create an exact countertop template and other surfaces that will be covered with marble, including splash guards. Mark precisely the openings for the sinks, the stove or any other cut that you will have to make to the marble plate. If you are installing a new sink, make sure that it will fit in the corresponding cabinet and that it is in the proper position before creating the template. This will allow you to make the necessary alterations to the cabinets to ensure a perfect fit. Be sure to include the protruding edges in the template. Once your customer has selected the color, pattern, and type of border, take the template to your nearest Home Depot or any other material supplier and order the custom countertop. If the new countertop needs more than one iron,

Steps to install marble countertops
Before beginning to install marble countertops, wrap the fronts of the cabinets with plastic to protect them from drops of adhesive and / or that workers reload on them with their tool belts, buckles, etc.

Step 1
When installing multiple countertop plates, start with the end pieces first and then insert the middle sections. Fit the front edges to make sure they are flat and level along the entire edge. Place shims on solid points on top of the cabinets, not in the middle of a long cut or fill piece. Make sure everything is tight, square, level and level. Any small variation can be sanded with an electric sander.

Step 2
Once the plates are adjusted correctly, remove them and apply the silicone adhesive. Place adhesive balls every 6 inches on the plywood substrate. If your installation does not require a substrate, place smaller balls on cabinet frames so that excess silicone does not drain from under the iron.

Step 3
Put the plates back in place carefully by first placing the back edge in place, and then lowering the rest of the iron until it touches the silicone. Be careful not to slide or push the plates, as it could smear the silicone and you won’t get the desired seal. Secure the iron at various points with the help of clamps to keep the assembly in place.

Install splash guards after securing the plates with clamps.

Apply an intensifier sealant to the countertop after installation. The intensifier will make the colors more vivid and the sealant will protect the stone.

Step 4
Once the plates are level and well adjusted between them, apply strips of masking tape along both sides of each joint. Apply the tape as close to the edge as possible to prevent excess epoxy from draining on the marble surface. Most epoxy adhesives need some pigment mixed to match or complement the color of the marble. Mix the pigment slowly until the desired color is obtained and then pour the mixture over the joints and use a spatula to force it into the joints.

Step 5
Overfill the joints, as any excess can be sanded when it dries. Mix a little more epoxy than you think you will need and be sure to fill in the joints completely, as it can be difficult to fill in the gaps or cracks, and repainting the same color as the first batch of epoxy can be difficult.

Step 6
While the epoxy joints dry, apply a smooth line of silicone adhesive between the top of the cabinets and the bottom of the countertop to seal these joints. Once everything is completely dry, remove the tape and use sandpaper to sand the excess epoxy and / or silicone adhesive.

Step 7
Apply an intensifier sealant to the countertop after installation. The intensifier will make the colors more vivid and the sealant will protect the stone. Advise your clients to reapply the intensifier sealant approximately every one or two years, or when they notice that spills are not cleaned so easily.
