Clear entire room of debris and remove any protruding nails or screws.
Also remove any quarter round or cove moulding in room.
Ensure subfloor is stable and install additional screws if necessary.
Mix and apply a thinset mortar that is suitable for the substrate as per instructions on Schluter Ditra packaging.
Apply mortar using a 5/16”x 5/16” V-notched trowel. This mortar mix should be soupy yet able to hold its shape when trowelled on.
Lay orange Ditra sheet in place (fleece side down) and press in place using a small piece of 2x4 or a trowel so that the fleece is solidly embedded in the mortar throughout. You can check by lifting the corner up and inspecting the underside.
Adjacent pieces can be laid by butting them to each other
Keep Ditra from edge of walls and from corners by approximately 1”
Tile can be installed over Ditra immediately.
Start by laying out your pattern.
Consider every wall that tiles will end against and ensure that you have the optimum centering position in the room. You don’t want any small cuts in doorways or against features in a room such as fireplaces. You can dry lay tiles two perpendicular rows of tile in the room to visually determine your layout. When you are satisfied with the layout and the positioning, mark the edges of your tile line-up.
Using a chalk line and your markings, snap guidelines to follow when laying tile.
Using a notched trowel, that is appropriate for the size of tile being used, apply the bonding mortar (ALWAYS USE UNMODIFIED MORTAR) and solidly embed tiles in the material. Ensure that the cavities of the Ditra matting are fully packed with mortar.
Start with the farthest full tile from the entrance to the room and work along your chalk line to ensure a straight run. Work your way to the front of the room laying only the full tiles. Use a level or a straight edge to ensure that the tile faces are flush. You can use spacers if you wish to maintain a consistent spacing between tiles.
Once the full tiles have set, you can then go back and cut and install all of the cut tiles in the room.
Once the cut tiles have set, clean all of the joints of excess mortar and grout the floor.
Install new quarter round or base cove moulding.
Straight cuts can be made using a manual tile cutter, a glass cutter, a wet saw or a grinder with a diamond blade. You can make circular or curved cuts using tile nippers or a grinder with a diamond blade.
Holes can be drilled using a diamond or carbide hole saw or a Dremel tool. To ensure the blade stays lubricated and cool, apply water to area while cutting using a spray bottle or hose. Use a cordless drill in order to avoid electrical hazards.
