How to tile an outdoor area

Adam_W

Difficulty: Intermediate

Tiling can be a great option for creating an attractive and low-maintenance entry or outdoor area.

 

The slip-resistance ratings you are most likely to encounter in Australia are P-value and R-value. In both cases, the higher the number the greater the degree of slip resistance.

 

Bear in mind that the tiles with the most slip resistance have coarser surfaces, so they collect more dirt and grime – and remember that you have to keep them clean to maintain their slip resistance.

 

Step 1

Thoroughly clean the area so that the tile cement will stick properly. Pressure cleaning is ideal, but heavily soiled areas should also be pre-cleaned with a product such as 30-Seconds Outdoor Cleaner.

Step 2

With your straight-edge or long level as a guide, use a pencil to mark a large grid with centre lines across your work area. Now try a few different tile layouts, using the marked lines to keep your tiles aligned.

 

In our case running our 600mm x 300mm tiles side-to-side made the area feel bigger. We made sure that our first tile, at the small step, was a full one, and we kept the cut tiles against the walls.

 

Tip: It’s important to allow enough tile overhang on a step. You need to allow for the thickness of the tile that will be used as kick-plate on the step face (riser), the tile cement beneath that face tile and a drip-lip of about 5mm on your top tile. You might find it easier and get better results if you install the face tiles first.

 

Step 2 Decide on your tile layout.png

Step 3

After you’ve decided on your layout, measure and mark your tiles for cuts. A tile cutter is an easy way to do this and gives you a professional finish. You can buy or hire a cutter, but make sure it’s big enough and has the right cutting wheels for the tiles you’re using.

 

Step 3 Use a tile cutter for professional cuts.png

Step 4

Use the mixing paddle fitted to your drill to mix a batch of tile adhesive in a bucket. The adhesive sets reasonably quickly, so don’t make big batches and run your drill at a low speed. Starting from a corner or wall, use the notched trowel to spread adhesive evenly over an area of a size that you can reach across to position your tiles.

Step 5

Lay tiles, starting at the furthest edge and working towards yourself. Check each tile with your level as you lay it. Spread new sections of bedding adhesive as needed. You can use exterior-grade painter’s tape to hold fiddly side tiles in place until the bedding adhesive sets. Painter’s tape won’t leave sticky residue on tiles. Use tile spacers standing on end at all corner joints. Spacers should never be laid down in corner joints as they are difficult to remove once the adhesive has set and they cannot be left in place and grouted over.

Step 6

Do not walk on the tiles until the adhesive has set. Once it has set, mix up grout and then use your squeegee to work it into all gaps, removing excess as you go. When the grout has set use a scrubbing brush to remove loose material before applying an acid wash mixed following the rates recommended on the label.

Step 7

For a professional touch, add trim (a smaller version of the skirting in a house) to hide the join between the tile and the wall. We used quarter-round or “quad”. For exterior use any trim must be H3 treated and painted on all sides before installing. Touch up any nail holes with suitable filler and paint afterwards.

Materials

  • Tiles, exterior grade with slip resistance rating of P3/R11 or higher

  • Tile cement

  • Tile spacers

  • Grout

  • Cleaning acid.

Tools

  • Tape measure and marking pencil

  • Short or torpedo level, long level or straight-edge

  • Notched trowel

  • Mixing bucket and mixing paddle fitted to suitable power drill. You can hire or buy "mixer" drills, or use a corded, variable-speed power drill of 800W or above or a larger battery drill with side handle fitted with a high-Ah battery pack.

  • Tile cutter and/or angle grinder with a suitable tile-cutting blade

  • Tile-grout squeegee

  • Scrubbing brush and cleaning sponges

  • PPE – Eye protection when cutting tiles and breathing protection if using angle grinder. Eye, hand and breathing protection when mixing and applying bedding cement and grout, and when acid cleaning.

Hi, is there a way to successfully tile over existing tiles (on a patio)?

Hi @torilee

 

Let me tag @Adam_W to make him aware of your question. Would it be possible for you to post a picture of your patio? We would need to see its current condition to make an assessment. We can then make recommendations if it's possible to tile over it. Can you please tell us a little bit of history about your patio? How long has the patio been there? Is it still in good condition? Anything you can tell us would be greatly appreciated.

 

If you have any other questions we can help you with, please let us know.

Hi @torilee

 

Thank you for posting that picture of your patio. Your patio looks to be in good condition. Just keep in mind that if you decide to tile over it, the current height of your patio will conservatively increase by 10mm. If this height interferes with your door entrance it will become a tripping hazard. I suggest checking your house entrance to make sure that there is enough height to clear the addition of new tiles in front of it. 

 

I recommend following @Adam_W's directions in preparing the area for tiling. I suggest using   Davco 20kg SMP Evo Tile Adhesive or Dunlop Universal Tile Adhesive. Both these products are rated for tile over tile use. Just make sure that you schedule it when it seems like there'll be sun for a least a week.

 

Please note that any loose tile or cracked tile must be repaired first before you tile over the old set. 

 

If you have any other questions we can help with, please let us know.

Hi, 

In preparing a slab for tiling, I was wondering how far I need to recess it so that the finished height is the same as the adjacent driveway. The tile I plan on using is 12mm.

Hello @Jujooi 

 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about tiling.

 

When using 12mm tiles the amount of adhesive used is about the same thickness. You would be technically using a QEP 12mm Square Notch Handyman Adhesive Trowel to spread the adhesive. Taking into account the amount of settling that will occur, lets say it goes down anywhere from 1 to 2 mm. 

 

This would give you a total height of 22mm with the glue and tile together. This would be conservatively the amount of space you would need to have in order for your tiles to line up with your driveway.

 

Would it be possible for you to post a photo of the area you are planning to tile? It will give our members a better idea of what your project looks like. We can then make recommendations on how to proceed.

 

If you have any other questions we can help with, please let us know.

Hi @Adam_W , this is great post, thank you.

Can you please explain how to lay tiles on a crusher dust please, i'm planning to put synthetic grass and outdoor tiles in my backyard, so i'm currently preparing the land with crusher dust, I would like to understand from you what's required to be able to lay the tiles on it if it's possible.

Thanks in advance.

Hi @ososbg crusher dust is suitable for laying paving but not tiles as such as the tiles need to be bedded into a tile cement to stay level and in-place.
There's a step-by-step guide I wrote on paving if that's of any use to you.

Hi @Adam_W , thanks for your quick response and for the link, my plan for this area is to be like an outdoor area with a table a chairs, would the pavers will be able to handle this or what other things I need to consider ? the area is about 2.5x5m.

 

Thank you.

@ososbg That’s the perfect situation for paving. Just make sure that everything is well compacted before laying them so they don’t sink or tilt from the pressure of chair legs.

Great, thanks Adam, one last question, this can work on any pavers with any size in there https://www.bunnings.com.au/products/garden/landscaping/paving-stones/pavers, is it right ?

Hello @ososbg 

 

Let me tag @Adam_W to make them aware of your question. I'm sorry, but the link you've provided is not coming up properly. Can you please provide us with the actual name of the paver you'll be using. 

 

Generally, any paver should work with your proposed layout unless it's extremely thin. As long as the area is flat and compacted, the pavers should sit in properly.

 

If you have any other questions we can help with, please let us know.

Thanks @EricL , I've not decided on the pavers, but i'm looking for something 60x60 or something like that from the Tuscan Path Taupe collection, for example

Tuscan Path 600 x 600 x 20mm Taupe Porcelain Paver

Hello @ososbg 

 

I'm sorry, but the Taupe Porcelain paver you've mentioned can only be laid over a concrete base. As an alternative, I suggest looking at the Brighton Masonry 400 x 400 x 40mm Charcoal Mypave Paver or the Brighton Masonry 600 x 300 x 40mm Charcoal Mypave Paver.

 

If you need further assistance, please let us know.

Hi, I've recently lifted two layers of old outdoor tiles from our front landing to expose the original concrete slab ready for re-tiling. I purchased an Ozito Rotary Hammer drill and chiseled away as much as I can, but the slab still isn't perfectly smooth, as it looks like the first layer of tiles were laid into a cement mix rather than adhesive. There are surface irregularities of only around 1 or 2 mm. Is this sufficiently smooth to apply tile adhesive, or will I need to have it completely smooth?

Many thanks.

Rod.

Hello @Smithrj 

 

If you're looking at knocking down that remaining 2mm of adhesive, I suggest using a Full Boar 125mm Double Row Diamond Cup along with a grinder. This will re-surface your un-even top and you'll have a good flat surface when applying tile adhesive. This would be a much better option than trying to level every single tile because of the uneven surface.
