How-To’s and Other Useful Watch-Out’s for Your Tiles

Even high-performance tiles need your care to last. So it’s handy to have a few simple preventive measures up your sleeves to keep them looking great.

DAILY
CLEANING

Daily Cleaning

Clean and sweep or vacuum your tiles regularly to prevent dirt from building up
A mixture of vinegar and warm water is a proven cleaning agent that’s also naturally gentle on tiles but you can also opt for a mild, soapless detergent as an alternative
Avoid abrasive cleaning agents to prevent minute scratches from appearing on tiles
To remove a stubborn spot, scrub with a paste of bicarbonate of soda and water
For remnant grout on tile surfaces, use only trusted grout cleaners to clean it off

PROTECTIVE
MEASURES

Protective Measures

Use good mats at doorways to keep out sand and grit which may scratch tiles outside
Avoid wearing spiked shoes on high-gloss or glazed tile floors as they may hurt your tiles
Use rubber gliders under furniture which may damage the surface of the tiles when dragged
Avoid dropping heavy objects on to the tiles
Be careful of gold and silver finishes on your tiles as they’re delicate and vulnerable to abrasive cleaning methods

PROACTIVE
STEPS

Proactive Steps

With wear and tear, one or two tiles may chip or crack, so always keep spares as you may not be able to find the same ones later
When laying tiles, ensure the tiler lays them evenly with no edges protruding up, and beds the tiles into the adhesive with no voids under the tiles
Always go through the tiles in the batch you’ve purchased with your tiler to ensure that flawed tiles are put aside, not accidentally installed
As the walls of your house move against each other with fluctuating temperatures, remember to check if the flexible sealant put in to accommodate these movements have become brittle or come away with age. If so, remember to replace them to prevent moisture from leaking through

What to Do When This Happens

1

Dirt & Stains

Concern

Why do my tiles get dirty or stained very easily?

Causes

Grout haze — Remnant grout that has trapped dirt on tile surface over time
Residual detergent — Improper rinsing will cause detergent residue to dry on tiles and trap dirt, causing them to look white
Improperly sealed tiles — Tiles that haven’t been properly cleaned or sealed during installation or usage of an inferior sealant
Spill — A spill that has been left on the tiles for too long can stain and penetrate the sealant

Solutions

Grout haze and residual detergent build-up:

Clean with a heavy-duty tile and grout cleaner and rinse off thoroughly. Otherwise, try a phosphoric acid cleaner with poultice Improperly sealed tiles
Carefully remove stains with a poultice, water and a white nylon scouring pad
Clean with heavy duty tile and grout cleaner
Seal only with reputable sealant in the market

  • Changing Shades

    Concern 1

    Why do some tiles of my tiles look darker than the rest?

    Causes

    Leak and excess moisture due to:

    A leak in the pipes behind the wall or failed water-proofing in wet areas
    Taps that haven’t been water-proofed and sealed where they meet tiles
    Constant flooding on floor due to bad drainage
    Cracked or dislodged tile grout

    Solutions

    Call plumber to check for leaks in the pipe-work or tap-ware
    Get tiler to repair faulty grouts or silicon joints that might be causing the leak
    Ensure drainage system in shower areas is working properly
    Never let water collect and pool on tiles for extended periods of time

  • Changing Shades

    Concern 2

    Why are of my tiles fading in colour?

    Causes

    Harsh acidic and alkaline detergents can cause tiles to fade over time
    Soap build-up in shower recesses or improperly cleaned grout haze can trap remnant soap and lead to faded look

    Solutions

    Replace faded tiles
    For prevention, use pH-neutral detergents (sparingly), and use only warm water

  • Defects

    Concern 1

    Why do some of the tiles I’ve installed look imperfect in parts?

    Causes

    Lack of quality control by tiler before installation, or tiles that have slipped past sorting and grading process in factory

    Solutions

    Before installation, talk to us about replacing affected tiles
    Examine your purchases prior to installation to avoid installation of faulty tiles

  • Defects

    Concern 2

    Why are there tiny spots or marks on my tiles?

    Causes

    ‘Tile blisters’ — These are tiny discoloured spots or marks on tiles which can sometimes slip past sorting and grading process in factory

    Solutions

    Avoid using affected tiles; check with us for replacements prior to installation
    Buy spares beforehand so you’ll have options available during installation

4


  • Scratches & Chipping

    Concern 1

    Why do my tiles have scratches?

    Causes

    Incidental scratches caused by friction between tiles during the journey between showroom and destination

    Solutions

    Speak to Johnson Tiles for replacements prior to installation
    Ensure tiler doesn’t install these tiles
    For light scratches on installed tiles, engage a glass repair service to remove them

  • Scratches & Chipping

    Concern 2

    Why are my tiles chipped in places?

    Causes

    Hard object that has been dropped or hard knocks caused by heavy objects
    Dragging of furniture with feet that aren’t capped with protective rubber
    Stones trapped in the soles of shoes that chip tile surfaces
    Imperfect glazing

    Solutions

    Remove affected tiles and replace them with new ones
    If chipping is due to imperfect glazing, call Johnson Tiles for assistance during installation

5


  • Cracks

    Concern 1

    Why are my tiles cracked in the corners?

    Causes

    Tiles with ‘firing cracks’ on them are faulty tiles that have slipped past factory sorting and grading process

    Solutions

    Do not install these tiles; talk to Johnson Tiles for replacements
    If some have already been installed, have your tiler replace them before installation’s completed

  • Cracks

    Concern 2

    Why are there cracked lines across my tiled floor?

    Causes

    Foundation ‘rod stress’ that occurs during the curing process of fresh concrete upon which tiles are laid
    Excessive movement in substrate caused by faulty installation of concrete foundation
    Absence of expansion joints along meeting point of two different surfaces, causing movement to travel through surface of tiles

    Solutions

    Replace damaged tiles
    Ensure tiler makes allowances for substrate movements with correct adhesives and expansion joints
    If allowances have been made, tiler needs to ensure joints used have been brought all the way to tile surfaces right from the start

6


  • Glaze Concerns

    Concern 1

    Why do my glazed wall tiles have hairline cracks on them?

    Causes

    ‘Crazing’ — A phenomenon when the two materials used in making the tile bond during the firing process
    Continuous movement of a substrate or structural wall

    Solutions

    Replace tiles if there’s enough of crazing to dissatisfy you
    If caused by movement in the substrate or structural wall, enlist the help of your contractor

  • Glaze Concerns

    Concern 2

    Why is the glaze at the edge of my tiles missing?

    Causes

    Flawed tiles have accidentally slipped past sorting and grading process at factory

    Solutions

    Check purchase and ensure tiler doesn’t accidentally install affected tiles
    Get replacements from Johnson Tiles; make a note of the batch number of your purchase in order to get new ones that match

  • Glaze Concerns

    Concern 3

    Why is the glaze on my tiles flaking off?

    Causes

    Kilns contaminated with dust have created bubbles in the glaze during firing process

    Solutions

    Avoid laying affected tiles; get replacements from Johnson Tiles
    Make a note of the batch number of your purchase in order to get new ones that match

7


  • Grout Matters

    Concern 1

    Why has my grout gone crumbly and soft?

    Causes

    Poor mixing and application that lead to ‘hydration’ syndrome, especially if tiler:

    Doesn’t wet the joints before applying grout
    Doesn’t fill whole grout joint and compress it into joint when grouting
    Uses old grout that’s past its expiry date or shelf life

    Solutions

    Ensure tiler wets the joints between tiles before installation to slow down hydration process
    Use rubber trowel and firm sweeping action across tile joints to compress grout into joint
    For crumbly grouts, scrape off old grout with grout rake and apply new grout mix properly

  • Grout Matters

    Concern 2

    How did my grout become dark?

    Causes

    Dirt from feet or water as well as detergent residue have collected in grout joints over time
    Mould has accumulated due to continued exposure to damp or wet conditions

    Solutions

    Scrub off grime in tile grouts with dependable, heavy-duty grout cleaner
    Once thoroughly clean and dry, apply grout sealant to make it water-resistant and easy to clean

7


  • Loosening & Buckling

    Concern 1

    Why do my floor tiles seem to be popping up?

    Causes

    Incorrect use of adhesive by tiler over concrete slab that’s still curing
    Lack of allowance made by tiler for substrate expansion around perimeter of tiled area
    Incorrect installation of movement joints

    Solutions

    Engage tiler to ensure movement joints can travel through tile and adhesive to the substrate
    Ensure movement joints are fully filled with flexible silicone or rubber compound
    For prevention, speak with tiler or Johnson Tiles before installation

  • Loosening & Buckling

    Concern 2

    Why do my wall tiles sound hollow and seem about to fall off?

    Causes

    Uneven application of adhesive behind tile base by tiler
    Installation done under very hot conditions and adhesive, left on wall too long prior to installation
    Water leakage behind tiles have caused adhesive-erosion

    Solutions

    Contact tiler to rectify flaws if wall tiles sound hollow upon installation
    If hollowness only surfaces after a while, post-installation, get tiler to inspect for possible substrate damage
