Can I tile onto a wooden floor?

Modern bathrooms look stunning with tiled walls and floors.  It creates the perfect haven for you to relax. However, chances are that your bathroom or en-suite has some kind of wooden flooring.  This could be either traditional floorboards or newer green chipboard slabs.

Is it easy to tile onto a wooden floor?

It is possible to tile onto a wooden floor but your floor must be prepped in advance to prevent problems in the future.

Why do I need to prep the floor?

The aim of prepping the floorboards is to create a wooden floor which is sound with no flexing. Basically, you are trying to reduce or remove the amount of flex in your sub-floor (the base layer of flooring).

What happens if I fail to prep the floor correctly?

Unfortunately, excessive flexing will cause your adhesive to come loose, possible de-bonding of your tiles and ultimately allowing the grout and tiles to crack.

Is it expensive to tile onto a wooden floor?

There are costs associated with prepping your floor but it will save money and hassle in the long run. You really don’t want to be replacing the floor a few months down the line because of inadequate preparation.  How depressed would you be to have a beautifully tiled floor start cracking and all you can do to fix the problem is rip it all up and start again?

Stages of preparation to tile onto a wooden floor

  1. Choose the overlay board to use.
  2. All boards must be screwed at 200mm centres.  Fixing further apart will limit the amount of flex you take out.
  3. If using No More Ply you will also need to use Mega Strength Adhesive to fix the boards.
  4. If required, apply one coat of primer to the wood as determined by the floor tile adhesive used. Allow to dry.
  5. Solid bed fix the tiles using Ultra ProFlex 2 part, a cement based highly flexible rubber crumb adhesive. For No More Ply boards ONLY, you can save money as you only need to use a single part flexible adhesive, 20kg Ultra ProFlex SP.
  6. Once dry, apply a cement based wide joint grout with added flexibility such as Ultra Flex Joint (3kg – several colours available) or Bostik SGS Flexible (10kg grey).

What different types of Overlay Boards can I choose from?

You can choose between a tile backer board, plywood, No More Ply or an alternative product. If using plywood, we recommend using a minimum 9mm board.

Will my floor tiles crack?

If you prepare the sub-floor correctly and use the right products, you are taking every effort to prevent cracks from appearing.

Is it better to remove the sink and toilet beforehand?

Yes, if your bathroom is completely empty it will help to speed up the process not only with over-boarding but also with tiling. Cutting around your sanitary ware can be quite time consuming.  If you don’t have to cut around the sanitary ware, not only will it save time, your tiling will have a neater finish.
