Can You Tile Over Floor Tiles?

Are you about to tackle a refurbishment or renovation project? If yes, then you might be worried about the removal of your old tiles before installing the new ones. Being fully aware that this process can be time and money consuming, it can only make sense to consider whether you can tile on existing tiles. The answer is yes, however, there are a few details you must take into account when embarking on this cost-effective journey. Here’s our advice:

lSelect The New Tiles

• Take into consideration the surface behind the tiles and the weight it’ll be able to withstand.

• For plasterboard, the surface can withstand about 30kg to 32kg per m2 (28.5kg of tile/square metre and 2.5kg to 3.5kg of adhesive and grout).

• For skimmed plasterboard, the surface can hold about 18kg to 20kg per m2 ( 16kg of tile/square metre and 2.5kg to 4kg of adhesive and grout )

• Consider the existing tiles, if heavy enough, then your choice for the new tiles should very light.

lPrepare Old Tiles

• Confirm that the old tiles are well glued to the substrate.

• Check that the tiles are level. If not, use a grinder to flatten out any humps.

• Remove the sealer for the old tiles, if any.

• Clear out all dust and dirt.

lLay New Tiles

• Spread a layer of flexible adhesive.

• Lay the new tiles

lFinish The Project

• Fill the joints with an appropriate tile grout.

• Seal the edges with a sealant.

It’s as simple as that! However, it must be said that if you’re lacking the appropriate training or experience to pull this off, then you probably would not want the first trial on your prized asset. For a top quality job and to avoid unnecessary costs, you can reach out to a tiling professional for help.

How To Remove Tile Floor

Removing old tile can be a very tricky process which require lots of skills and experience to get right, the first time. Here, you’ll learn the best approach to removing your old tile by yourself. During the removal process, be sure to incorporate the necessary tools while also protecting yourself by putting on the recommended safety requirements. These includes a floor scraper, paint scraper, dust mask, handheld chisel, safety glasses, drop sheet as well as leather gloves or top quality riggers.

Tile Removal Process

lBreak The First Tile

• Use a hammer to break the first tile (target the centre of the tile with the hammer).

• To protect yourself from the sharp edges of the broken tile, use a drop sheet to cover the surfaces.

lRemove The First Tile

• With a chisel, remove the broken tile that’s still bonded on the floor.

• Position the chisel on the grout line at the tile’s edge to remove the broken but glued tile.

lBreak Up The Remaining Tiles

• Break up several tiles at once and use the floor scrapper to remove it.

• Ensure that the bonding agent used is pliable to make the job a soft work. If the bonding agent is a bit more permanent in nature, then you might want to consider a dynamite to dislodge the flooring.

lRemove The Mortar

• Hit the mortar with a hammer on a 2 to 3 foot square section to remove it from the underlayment.

• Scrape off the mortar’s broken pieces using a floor scraper

• In the event whereby most of the mortar is not removed, your best bet would be to change the underlayment.

• Bonding agent (adhesive) removal is not the easiest of tasks. To make it a bit simpler, you can softening the adhesive with a heat gun before scraping with the help a wide putty knife.

Tile removal is not only a tedious task, but can also be harmful if adequate care is not taken. If you’re inexperienced or not well trained, we’d recommend you hire the services of a professional to avoid making mistakes and incurring extra costs.

How To Lay Tiles On Concrete

Installation of tiles on concrete sub-floors can be done with relative ease under adequate guidance. Here is what you have to do.

lPrepare The Concrete Subfloor

• Ensure the concrete is dry, clean and must be at least 6 weeks old.

• If there are dips and humps, level the concrete using a levelling compound.

lSet Out

• Working from the centre outwards, take a measurement of the floor (both length and width) and draw a cross at the centre.

• Lay out the tiles from the cross with a space of 3mm between each tiles. This will allow for movement stresses within the floor and later to be filled with grout upon installation of the tiles and adhesive dried.

lCut The Tiles

• Due to the particularly had nature of some floor tiles such as natural stone and porceclain, high quality tools are usually required to produce a clean cut through the tiles. With the help of an electric wet cutter alongside a slide cutter and nippers, your job would be made a lot easier.

• For a better result during intricate cuts, make use of a cardboard template.

lFix The Tiles

• The tiles should be fixed using a cement-based adhesive.

• Ensure to refer to the packaging or product data for the mixing ratios information.

• Stir the mixture till its lump-free

lApply The Mixture

• Spread the mixture onto the concrete sub-floor to create parallel ribs with the help of a floor trowel.

• Push the tiles into the parallel ribs.

• Clear out any excess adhesive from the tiles surface with a damp sponge.

• Do not walk on the tiles for at least 2 hours.

lGrout

• Once the adhesive is dried, wipe out any dust, adhesive or dirt from the tiles’ gaps.

• Mix about 4 to 5 parts of grout powder with 1 part of water and ix together.

• Apply the mixed grout diagonally across the tiles using a soft rubber grout float.

• Wipe out excess grout from the tiles surface and allow the tiles to dry.

• Stubborn residues can be cleaned using any washing up detergent with warm water within 24 hours after grouting.

Removing floor tile is always a simple task until you get started. Then, you’d realize not only is it a tedious and time consuming task, but also one with multiple hidden challenges that’s only revealed once the project is underway. If you have no experience or perhaps you lack the confidence required to pull this off, we’d highly recommend you call in a professional who can guarantee the best outcome and save you some unnecessary spending. However, if you wish to tackle this yourself, this guide would be your perfect partner to ensure a successful outcome.

To get started, you’ll need the following tools; hammer, chisel, pry bar, scraper, trash can as well as a broom or shop vac.

1. Remove fixtures. Ensure the room is empty and remove all fixture that may get in the way.
2. Pick a starting point. Use a hammer and chisel to chip out a tile and create a starting point for the task. Depending on how the tile is affixed and the underlayment type incorporated, the tile may remove easily or require some effort. Use a hammer, chisel, pry bar or pole scraper to remove the tiles.
3. Remove the tiles. From the starting point created, proceed to pry up the tiles. Deposit then in a trash can or large bucket in order to reduce clutter.
4. Access underlayment. There are cases whereby the tiling is attached directly to a concrete floor or subfloor, however the common practice is having a plywood or mortarboard underlayment. The damaged underlayment should be detached to expose the subfloor.
5. Clear debris. Wipe out all debris from the floor using a broom or shop vac.
6. Remove nails. If you removed the damaged underlayment, you may have to either remove or pound in some nails to get a level surface.
