Granite counters are a great embellishment for a kitchen or bathroom. By its nature, granite is not easy to handle. But now there are pre-shaped models on the market, with detailed installation instructions that make them suitable even for beginners. If you need to install a counter in an area that has more than one corner or has a particular shape, you should consult a professional. In other cases it shouldn't be difficult to install a one- or two-piece surface following these instructions.

![Install Granite Countertops Step 24 Install Granite Countertops Step 24](https://i.sundulerparents.com/images/009/image-25339-24-j.webp)
Step 3. Add 3% catalyst to the resin
Apply the resin to the joint with a putty knife. Repeat with the other colors until you find the one that matches best. Work quickly, as once the catalyst is added the resin hardens quickly.

Step 4. Once the application is finished, remove the tape
When the resin dries you can smooth it with the special tool.
