• If the surface is too smooth, consider lightly sanding to improve adhesion.

Do's	Don'ts
Clean thoroughly.	Skip repairing damage.
Ensure surface is level.	Leave loose or chipped areas.
Roughen smooth areas.	Flood the area when cleaning.

Drying the Surface:

• After cleaning and repairs, let the concrete dry completely. This can take 24 to 48 hours depending on conditions.

Properly preparing the concrete surface is a vital step to ensure the success of your outdoor tiling project.

Planning the Layout

When laying outdoor tiles on concrete, planning the layout is a critical first step. Start by measuring the area to determine how many tiles you need, keeping in mind to accommodate for cuts and waste. Use these measurements to create a scale drawing of the space.

Measuring Your Area:

• Length: Measure the longest side of the area.
• Width: Measure the side perpendicular to the length.

Next, decide on the orientation of your tiles. Do you prefer them aligned with the walls or diagonally placed? This decision influences the visual impact and the number of cuts required.

Tile Orientation Options:

1. Straight: Align tiles parallel to walls.
2. Diagonal: Place tiles at a 45-degree angle to walls.

Marking the Starting Point:

Identify your starting point. It could be the center of the space or an edge, depending on your preferred layout pattern. This ensures you achieve a symmetrical finish.

• Center Start: Tiles radiate evenly from the middle.
• Edge Start: Full tiles at one boundary may mean cuts at the opposite.

Dry Layout Trial: Before applying mortar, lay a row of tiles without adhesive to get a sense of the end result and make necessary adjustments. Check for:

• Tile Fit: How tiles lie against walls or fixtures.
• Tile Cuts: Identify where and how many cuts are needed.

Lastly, when certain of your layout, mark reference lines on the concrete to guide your installation. These guidelines help to maintain a straight and professional-looking tile arrangement.

Mixing and Applying the Mortar

Before you begin mixing mortar, ensure you have all necessary materials and tools at hand, including a bucket, trowel, mixing paddle, and electric drill.

Materials Needed:

• Mortar mix
• Water

Tools Required:

• Bucket
• Electric drill with mixing paddle
• Notched trowel

1. Measure the Mortar Mix: Start by reading the manufacturer's instructions on the mortar bag. Measure out the amount required for the area you are tiling.

2. Add Water: Pour the recommended amount of water into the bucket first to minimize dust.

3. Mixing Process: Slowly add the mortar mix to the water while the mixing paddle attached to the electric drill is on a low speed setting. Mix until you achieve a smooth, peanut butter-like consistency. Let the mortar sit, or “slump,” for about five to ten minutes, then mix again briefly before applying.

4. Applying Mortar: Use the flat side of the trowel to scoop and spread a thin layer of mortar onto the concrete, covering an area slightly larger than the tile. Then, using the notched side, comb over the mortar to create even ridges.

5. Setting Tiles: Press tiles firmly into the mortar, using a twisting motion to ensure good adhesion. Be mindful of maintaining consistent spacing and alignment by using tile spacers.

Remember: Do not mix more mortar than you can use within a 30-minute period, as it will begin to set and become difficult to work with. Always check the mortar's working time and follow safety precautions indicated on the packaging.

Laying the Outdoor Tiles

Before starting, ensure your concrete is clean, dry, and level. Imperfections can affect the tile placement, so be attentive to the surface condition.

Materials Needed:

• Outdoor tiles
• Mortar
• Notched trowel
• Tile spacers
• Level
• Tape measure
• Chalk line

Step 1: Planning Measure your area and plan the layout to avoid narrow tile strips at the edges. Use a chalk line to mark your guide for the first row of tiles.

Step 2: Mixing Mortar Mix your mortar to a peanut butter consistency. If it's too wet or dry, it won't hold the tiles properly.

Step 3: Applying Mortar Use a notched trowel to apply an even layer of mortar. Comb the mortar with the notched side to create uniform ridges.

Step 4: Laying Tiles Set the tiles onto the mortar with a slight twisting motion. Ensure they are level and straight. Insert spacers between the tiles to maintain even gaps for grout.

Step 5: Cutting Tiles For edge tiles, measure and mark your cut line on the tile. Use a tile cutter to achieve accurate cuts for fitting.

Step 6: Setting Tiles Allow the tiles to set in the mortar as per the manufacturer's recommendations. Walk on the tiles only after the mortar has fully cured.

Remember:

• Double-check tile level after placement.
• Use safety equipment when cutting tiles.
• Keep joints clean for grouting.

Cutting Tiles for Edges and Corners

When laying outdoor tiles on concrete, you'll often need to cut tiles to fit edges and corners. It's crucial to measure accurately and use the right tools for a clean, precise cut.

Measuring and Marking:

• Measure the space where the cut tile will be placed.
• Transfer these dimensions to the tile, using a straight edge to draw your cut line.
• Make sure to subtract the space for grout lines in your measurement.

Tools for Cutting: Choose your tool based on the tile material:

• Tile Scribe: for scoring and snapping thinner tiles.
• Wet Saw: for cutting thicker tiles and natural stone.
• Tile Nippers: for making curved cuts.

Cutting with a Wet Saw:

• Secure the tile to the saw's platform.
• Align the cut line with the saw blade.
• Cut the tile with a steady, slow push to ensure a smooth edge.

Snapping the Tile:

• After scoring with a tile scribe, place the tile on a solid surface.
• Apply pressure along the score line for a clean break.

Smoothing Edges:

• Smoothen rough edges with a rubbing stone or sandpaper for a finished look.

Safety Tips:

• Always wear safety glasses to protect your eyes.
• Gloves can prevent cuts from sharp tile edges.

Practice Makes Perfect:

• Consider practicing on spare tiles to perfect your cutting skills before attempting the actual project tiles.

Applying Grout

After your outdoor tiles are securely set in place on the concrete and the adhesive has dried, it's time to fill the joints between the tiles with grout. Begin by selecting a grout suitable for outdoor use to ensure longevity and resistance to the elements.

Materials Required:

• Outdoor grout
• Rubber grout float
• Grout sponge
• Clean water
• Buckets
• Grout sealer (optional)

Step 1: Mixing Grout

Mix the grout according to the manufacturer's instructions until you achieve a smooth, peanut butter-like consistency. Let the grout sit ('slake') for a few minutes if required by the product instructions.

Step 2: Applying Grout

1. Using a rubber grout float, apply grout at a 45-degree angle to the tile surface.
2. Press down firmly to ensure the grout fully penetrates the joints.
3. Work in small sections to maintain control over the grout's drying time.

Step 3: Cleaning Excess Grout

• Wait for the grout to set slightly — typically 15 to 20 minutes.
• Gently wipe the tiles with a damp sponge to remove excess grout. Rinse the sponge frequently.
• Be cautious not to remove grout from the joints.

Step 4: Final Touches

• After 24 hours, check for any grout haze on the tiles and buff it off with a soft cloth.
• Optional: Seal the grout with a silicone-based sealer for added protection.

Remember to wear protective gloves and take your time to achieve a professional and durable finish. Regular maintenance will ensure the longevity of your outdoor tiling.
