Installing granite countertops on concrete requires a selection of tools that suit your intended goal. The countertop installer won’t use foreign materials but a caulk gun, personal protective gear, silicone caulk, earplugs, a diamond blade, and a circular saw. However, they should also obtain these instruments in conjunction with them.

4. Clear Away the Previously Installed Countertops

You should remove the old countertops carefully to avoid damage to the concrete base. With a utility knife, cutting the part off from the base is a simple task that you can do. But if the old countertop is still firmly attached, lift it with a broom and throw it away slowly and carefully. This step is crucial to prevent any damage to the concrete base, especially if you plan to have granite countertops installed, as they can be messed up if the base is not in good condition.

5. Correctly Measure the Concrete Slabs

Accurately measuring the granite countertop size is crucial to ensure successful installation.

  1.   Use a measuring tape to measure the concrete area.
  2.   Consider the obstacles and corners.
  3.   Double-check your measurements to avoid mistakes.

6. Reinforce and Secure the Countertops

This step is one of the most vital ones in the installation guidelines for granite countertops to concrete because it ensures flawless placement of the granite slab. You should clear away the debris and level the concrete base with sandpaper. Check to see if reinforcement and security require plywood or additional support brackets.

7. Carefully Cut the Granite

You should contact countertop-supplying companies like Granite Nations to learn if they will bring the already-cut granite to the location or have it cut at your home. If the granite is cut at the client’s house, they should know the process.

  1.   Transfer the measurements onto the granite slab and double-check them.
  2.   The installation team can use various tools and equipment to cut the slab, like a wet saw with a diamond blade.
  3.   They may take their time and follow all safety instructions for installing granite countertops to concrete.
  4.   They may carefully cut the granite, wearing gloves and goggles for protection.

8. Check the Fitting of the Slabs

Before permanently fixing the granite slabs, check if they fit perfectly. Place the freshly cut granite on the concrete surface and ensure you have cut it correctly. You can also make on-the-spot adjustments, like trimming the corners and edges.

9. Apply Adhesive on the Concrete

After confirming that the granite is cut correctly and fits perfectly on the concrete base, it’s time to apply the adhesive. The installation team will lift the granite carefully and use construction adhesive. This solution is specially designed to keep heavy construction materials bonded together.

10. Place the Granite Slab and Secure It

The team will carefully place the granite on the concrete surface and press it down firmly. To check if the granite slab is sitting evenly, use a level. This is a vital step of the granite installation process for concrete countertops because it ensures durability and longevity.
