Sintered Stone Flooring Install: A Step-by-Step Guide

Understanding Sintered Stone Flooring

With its exceptional durability and low maintenance, sintered stone flooring is gaining popularity in residential and commercial settings. This guide will provide a detailed installation process overview, addressing key concerns to help you make informed decisions.

The Unique Nature of Sintered Stone

Sintered stone flooring, such as MERQI Sintered Stone, is prized for its strength and resistance to wear. However, its rigidity demands meticulous installation to prevent damage.

Pre-Installation Considerations

Before you begin, inspect the sintered stone for any defects like discoloration, bubbles, cracks, or warping. A pristine starting point is essential for a perfect finish.

Substrate Preparation

Ensure the substrate is smooth and level by removing any loose particles and debris.

Tracing and Grid Layout

After allowing the base to settle for 3-4 days, mark the surface for segmentation and grid layout. This step is crucial for maintaining the flatness of the final surface.

Adhesive Preparation

Prepare the adhesive according to the product instructions, using an electric mixer to ensure a uniform consistency.

Adhesive Application

Apply the adhesive to the substrate using a notched trowel, creating a uniform layer. The thickness of the adhesive should be adjusted based on the size of the sintered stone tiles.

Back Coating of Sintered Stone

Apply a layer of adhesive to the back of the sintered stone, approximately 6-8mm thick, using a notched trowel.

Laying the Sintered Stone Tiles

Install the sintered stone from the center outward, ensuring full coverage of adhesive to prevent hollow sounds. Use spacers to maintain consistent grout lines.

Compaction and Leveling

Once the sintered stones are placed, use a rubber mallet or plastic plate to tap the sintered stone into place, ensuring a flat and even surface. The adhesive can be adjusted within 30 minutes of application.

Using Leveling Tools for Joint and Leveling Assistance

Utilize leveling tools to assist in maintaining even grout lines and a level surface.

Hollow Sound Inspection

After an hour of installation, check for any hollow sounds by tapping the tiles with a rubber mallet. Any tiles that produce a hollow sound should be relaid.

Joint Cleaning

Before the adhesive fully cures, clean out any excess adhesive from the grout lines. Use a flexible grout for filling, ensuring a uniform width of at least 3mm.

Surface Cleaning

Clean any contamination on the sintered stone surface without causing tile movement. After the installation is complete, use a neutral cleaner to thoroughly clean the surface.


Mastering the installation process of sintered stone flooring is vital for making informed purchase decisions. By following these steps and considerations, you can achieve a high-quality, durable, and aesthetically pleasing flooring solution. Remember, precision and care are key when working with sintered stone.
