Tiling over Timber Floors

Product System

System Overview

 CLEANING, SHEETING & PRIMING

All floor Substrates are to be fixed and secured as per manufacturers instructions.

All substrates are to be checked for soundness, cleaned, swept, vacuumed and wiped over before works can begin.

Once cleaned and prepped, the installation of Ceramic Tile Underlay (CTU) can commence. Ceramic Tile Underlay should be installed as per manufacturers instructions. Once sheeting is completed the floor sheeting needs to be primed using SAS Tradies Choice Master Primer and should be applied with a sponge or roller ensuring full coverage to all surfaces. Tradies Choice Master Primer is to be diluted-3parts water to 1 part primer.

For wet areas, once primer has completely dried, Polyurethane sausage can be applied to all substrate intersections as bond breakers and tap/spout penetrations. When P/U has cured, waterproofing can commence.

*Please refer to SAS Tradies Choice WATERPROOFING spec sheets.

SCREEDING IN WET AREAS

For screeding over Ceramic Tile Underlay in wet areas, please follow information set out in the SAS Tradies Choice Waterproofing & Tiling Bathrooms Specification            

WALL AND FLOOR TILING 

After all waterproofing membranes and screeds are fully cured, set out tiling. Floor tiles must be laid first and once dry, wall tiling can commence.

TILE INSTALLATION

Tiles should be fixed in accordance with Australian Standard AS 3958.1-2007 Apply the adhesive using a notched trowel onto the substrate. For tiles up to 300 x 300 mm use a 10mm notch trowel, and for Tiles greater than 400 x 400 use a 12mm notch trowel on the substrate and butter the back of each tile. Apply only up to 1m2 at a time. Press the tiles firmly into the adhesive before it skins. Do not spot fix, remove all excess adhesive from the tiles before it sets. Tiles should be fixed in accordance with the Australian Standards AS3958.1-2007.

Ensure the back of each tile is clean free form dust and other contaminants.

Apply the adhesive onto the substrate but do not exceed more than 1m2 at a time.

When back buttering is required use the straight side of the trowel and apply a thin coating of adhesive onto the tile.

When laying the tiles make sure you move the tile forward and back 90 degrees across the direction of the beads of adhesive leaving no voids under the tile. It is important to lift a tile every now and then to check that sufficient coverage is achieved 90-100%.

All adhesive residue must be removed from the tile and joint while the adhesive is still wet.

For all other applications not mentioned please contact the SAS Technical team.

Note: Protect tiling from other trades and weather. Do not allow traffic until all the tiling and grouting is completed For information not listed please contact SAS  for further information

PRECAUTIONS

All Tile installations must comply with Australian Standards AS-3958.

Expansion/movement joints in the substrates must be continued through tile finish and screeds.

DO NOT use premixed adhesives  to bond tiles over membranes as prolonged drying will occur.

Always protect tiling work in progress from bad weather, inundation of water and from other trades until such time all works are completed.

Do not use SAS Tradies Choice Waterproofing membranes, Adhesives or our LITOKOL Grouts below 50Cor above 350C

GROUTING

When all adhesive is dry/cured and all spacers have been removed from all joints. Clean up ready for grouting can begin.

Be sure to scrape out any excess adhesive that was missed during tiling so joints are empty. Vacuum all joints and prepare the grout. We recommend our LITOKOL Cementitious or Epoxy range of Grouts.

CAULKING/SILICON WORK

Once grouts have completely cured, caulking/silicon of all internal and external junctions can commence. 

Always leave the finished job clean, tidy and protected from other trades.
