The floor tiles in the living room should have gaps, so is it better to leave wide gaps or narrow gaps in the floor tiles? Answer: There are generally two kinds of seams left in living room floor tiles, wide seams and narrow seams. Narrow seam: commonly used in vitrified brick masonry, generally, it is enough to leave a seam 1- 1.5 mm, and at the same time, use a jointing agent close to brick color for jointing treatment. Pay attention to leaving seams when paving, mainly considering the shrinkage of thermal barrier. Wide seam: commonly used when paving antique bricks. Generally, the joint is 5-8 mm, so you can choose the jointing agent close to the color of the brick body or the jointing agent with strong contrast to deal with the brick joint.
