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.

Do you wish to have your residential or commercial space tiled? With a plethora of benefits that comes with a tiled floor, it’s little surprise more and more home and property owners are going for this special flooring type. Not only are they able to improve the curb appeal of any property, but they’re also resistant to moisture helping to increase the durability of the house – be it wall or floor tiles.

Tiling a floor is not the simplest of tasks and should be done with utmost care and attention to details. If you lack the confidence to pull this off, we’d recommend you hire a reputable professional who can guarantee the best outcome the first time.  In this guide, you’ll find processes involved in floor tiling to help put you in the right direction.

Floor Tiles Installation Procedures

1. Floor Preparation
   The first step is to prepare the floor by moving all objects like mortar, adhesives and more. Use concrete patching compound to fill ill low spots and cracks, until the floor is levelled.
2. Ensure the floor is dry and clean.
3. Pattern Layout
   Take the measurement of each wall’s length while also taking into account the room’s diagonals.To help place the tiles in an orderly manner, make use of a chalk to mark down lines on the levelled surface in question and ensure it’s parallel to the walls.
4. Adhesive Preparation
   Mix the appropriate amount of water with the adhesive (bonding agent). The mixture should be toothpaste-like thick to ensure the durability of the tiles.
5. Tiles Placement
   Depending on the tile’s size, evenly spread the mortar on the floor using a notched trowel. Lay the first tile on the bonding agent (adhesive or mortar) and apply a gentle and little pressure on the tile.
   
   Repeat the technique for other tiles using plastic spacers to ensure the edges and corners are properly aligned.
6. Tiles Cutting
   Cut the tiles (if necessary) with the help of a wet saw or scoring cutter featuring a diamond-tripped blade.
7. Grout Application
   Filling of the tiles’ gap is done using the grout. It can be applied to the joints with a rubber float. After application, allow the grout to set up for some minutes. Use sponge and a bucket of water to clear out any adhesive leftover.
8. Grout Sealing
   Use a foam brush or applicator bottle for the sealants’ application. Clean out excess sealer within 10 minutes.

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.
