Site Preparation

For our team to commence work, please ensure that all necessary preparation work is completed:

  • All surfaces to be tiled are level, firm and rigid enough to hold the weight of tiles.
  • Loose or damaged sections should be fixed or patched and allowed to dry.
  • Screws, nails or any other items sticking out have been removed or made flush.
  • Plumbing and electrical work has to be complete and isolated where necessary.
  • All architrave’s and trims need to be fitted.
  • Timber floors must be prepared and sheeted with a quality tile underlay and glued and nailed to comply with the Australian Building Code.

Just a few points you need to note - or tell your builder:

  • All joints on wall sheets should be left unplastered in shower areas.
  • Try to avoid having a joint in the sheeting on the shower floor area.
  • Sheeting on all external corners should be “point to point” and not “butt” joints.
  • All showers require a minimum 50mm waste to accept a puddle flange.
  • Where channel drains are being installed the centre of the waste pipe needs to be set back off the wall by between 100mm – 150mm.
  • Apart from channel drains the best position for a shower waste is dead centre.
  • No vanities should be fitted until waterproofing and cement bedding is completed.
  • Do not paint any areas that are to be tiled.

Painted Surfaces

Paint is not designed to hold the weight of tiles and ideally should be removed. However, if this is not possible you’ll need to roughen the surface of oil based paints mechanically (such as with a grinder or sander), and a cement based tile underlay board should be fixed over the top of all water-based and PVA paint.  Tilers and Waterproofers can take care of this for you!

Concrete Floors

Before tiling, new concrete floors should be left to cure for a minimum of 6 weeks to allow for shrinkage. However some specialist adhesives are available if tiling must be done before this full curing period. Check that the floor is straight and true, and wherever necessary, self- levelling compounds may need to be applied. Tilers and Waterproofers can take care of this for you!

Plastered Walls

If there’s new plaster on your walls you’ll need to make sure it’s had enough time to dry, usually 3-5 days. New plaster may still need a coat of primer before tiling.

Wooden Floors

If you’re planning on tiling over wood, you’ll need to prepare the surface with cement tile underlay sheets. These sheets should be glued down and nailed at 150mm centres throughout the whole sheet. All of the joints need to be butted and nailed at 100mm intervals. Your tiles can then be glued straight onto the cement sheeting, so no further preparation is needed.  Tilers and Waterproofers can take care of this for you!

Existing Tiled Areas

We often get asked if it’s alright to tile over the top of existing tiles. The simple answer is yes — there are special adhesives designed specifically for tiling over tiles. But, in the majority of cases, it’s better to just remove the old tiles first, especially in bathrooms and wet areas where condensation may occur. 

If removing the old tiles isn’t an option, then all of the grease and dirt will need to be removed with a suitable detergent.  The tiles may then have to be mechanically scored to ensure the new tiles will stick. Care must be taken to ensure all existing tiles are firmly bonded and in a sound condition.

Other Surfaces

Cushioned vinyl, lino or thermoplastic tiles and their adhesive must be removed.
