To install laminated rubber tiles for a seamless finish, start by cleaning and preparing the subfloor, ensuring it's dry, level, and smooth. Apply a high-quality adhesive using a notched trowel. Lay tiles, starting from the center, and press firmly for adhesion. Use spacers to maintain even gaps. Trim edges for a snug fit. Finally, roll the floor with a heavy roller to ensure proper bonding and a smooth, seamless appearance.
