Tile Fixing and Maintenance from The London Tile Co.

We want you to be totally happy with your new tiles and making sure that they are installed and looked after properly is a big part of that. Read our guide to fixing and maintenance below for tips and advice.

Checking Your Tiles

The most important thing you can do is check your tiles carefully as soon as they are delivered. Although we do our best to avoid picking and quality problems these do occasionally occur and it's best for everyone if we know about these as soon as possible. Any issues must be reported to us within 14 days of delivery of your order. Once the tiles have been installed we cannot do anything, so it is imperative you check you have received the correct tiles and are happy with the colour, shading, calibration and sizing before they are installed. If you have any questions please get in touch with our customer services team.


When tiles are fired in a kiln they can come out slightly bowed. This is usually only a small amount which is not noticeably once the tiles have been installed. In longer tiles, such as planks or large oblong shaped tiles, this can seem more pronounced - particularly if the tiles are laid in a stack bond pattern. If a wider joint is used the lipping will be less obvious, however with more large format tiles being finished with a rectified edge (a very precise square profiled ground edge) and a narrow joint, the problem becomes more apparent.

Before fixing lay the tiles out on a flat surface and butt-joint in the pattern you will be using to check if there will be excessive lipping. If lipping looks excessive try laying the tiles out in a 1/4 or 1/3 broken bond pattern, or use a square bond.

The European standards for bowing are as follows;

  • Centre curvature for Porcelain B1 is +/- 0.5% of the diagonal size.
  • For porous tiles B111 it is +0.5%/-0.3% of the diagonal size.
  • Installation

    Make sure you are using a suitable adhesive for your substrate and tile material. As part of the Hampshire Tile Warehouse group we have over 65 years experience in the tile industry so give us a call if you have any questions about the best type of products and preparation for installing your tiles.

    In larger tiled areas movement joints, or expansion joints, may be required to avoid the tiles cracking, bulging, debonding, and/or tenting. All tiles will expand and contract due to changes in temperature and moisture, and almost all substrates will move differently to their tiled covering. We recommend including expansion joints at intervals of at least 6m for heated floors, and 8m for unheated floors. Therefore if your room measures only 3m wide but is over 8m long, you will need to add an expansion joint.


    The majority of our porcelain and ceramic do not require sealing. If you are using a natural stone product a specialist sealant can be used to protect and enhance the look of the material. Some tiles such as polished porcelain or those with a crackle glaze finish do require sealing to protect the tiles against staining - this does need to be done prior to grouting.

    External Tiles

    Our range of external porcelain tiles can be installed using one of three recommended methods; onto a solid base using tile adhesive, onto terraces or balconies using Eterno Ivica pedestals, or onto MOT type 1 sub base using PorcelQuick Adpeds. See the external porcelain installation and fact sheet for information regarding the installation and maintenance of your outdoor tiles.
