Considerations Before Installation

Process of Installation
The process of installing porcelain countertops over existing ones typically involves several key steps:
- Preparation: Thoroughly clean and inspect the existing countertops. Repair any damage and ensure they are level and stable. Remove any old sealants or adhesives that could affect the new installation.
- Measurement and Cutting: Accurately measure the dimensions of the existing countertops and cut the porcelain slabs accordingly. Precision is essential to ensure a proper fit and alignment.
- Adhesive Application: Apply a suitable adhesive recommended by the manufacturer to both the existing countertop surface and the underside of the porcelain slabs. Follow manufacturer instructions regarding adhesive type, coverage, and drying times.
- Placement and Alignment: Carefully place each porcelain slab onto the adhesive-covered existing countertop. Ensure proper alignment and adjust as necessary to achieve a seamless fit.
- Sealing and Finishing: Once the porcelain slabs are in place and the adhesive has cured, apply a sealant to the seams and edges as recommended. This helps to prevent moisture penetration and enhances the durability of the countertops.
