How to Lay Porcelain Tiles for Outdoor Space

Laying porcelain tiles is just as easy as laying slabs like natural stone. For a stylish makeover and to bring home the elegance of porcelain tiles, you must follow each step with utmost care. Once you are done installing these tiles, you’ll get a completely new look to your outdoors. So, here are the step-by-step instructions to install porcelain tiles for outdoor space.

Step 1 – Marking is Important

Before preparing your tiles or base mixture, you should mark out the area with string and posts where you want the porcelain tiles to be. Calculate the area, and according to that, purchase your porcelain tiles. You should buy some extra pieces if there are any damaged tiles.

Step 2 – Protect Your Porcelain Tiles

Porcelain tiles don’t need to be sealed as they are not porous. But for the safer side, apply a layer of tile protector, so the mortar and slurry do not get ingrained in the surface and make the cleaning post-installation a lot easier. You can use a foam roller to apply the coating to the surface of the tiles. But make sure you only coat the surface, not the edges, as this can weaken the grout bonding.

Step 3 – Prepare the Ground

Once you are done with the protective coating, start digging the ground where your porcelain tiles will be installed. Dig to a depth of around 160-200mm, and make sure to add a bit of slope to allow water drainage. Make sure to give the slope that will drain the water away from your home.

Step 4 – Prepare the Base for a Strong Foundation

You need to make a strong base mixture that guarantees the proper placement of porcelain tiles. As your outdoor area expects traffic the most, you must ensure they are correctly placed on a solid base.

First, fill the dug-out area with gravel and crushed rocks to a depth of around 100-15mm and spread it evenly. Use a spirit level or line level to check that your ground has enough slope. You should not forget to give a slope of 1:80 for water drainage. Once you are done, apply a mortar mixture of 4 parts sharp sand and 1 part cement to lay a strong foundation.

Step 5 – Apply Primer to Your Tiles

Apply a layer of primer to have a strong grip between the tiles and the mortar bed. Take a bucket full of clean water and add the slurry primer powder. Mix it well for up to five minutes to create a smooth and lump-free consistency. Apply this mixture to the underside of the tiles to make them stick properly with the mortar bed.

Step 6 – Installing Porcelain Tiles for Outdoor Space

Once you are done with the primer coating, start installing porcelain tiles for outdoor space. You should begin placing the porcelain tiles from the corner. Lay all the tiles, leaving a gap of around 4-5mm between each tile. Once you are done placing a tile, press it into place and adjust the level using a spirit level and rubber mallet. Don’t forget the water drainage.

Step 7 – Fill the Grout

Now give the finishing touches to your porcelain tiles for outdoor space. Infill the joints with grout for outdoor tiles specially designed for exterior use. Fill them evenly and use a pointing trowel to firm the grout into place.

Once you are done with the complete installation process of porcelain tiles for outdoor space, leave it for around 24 hours to allow it to dry. Avoid walking on the surface till it gets dried. Clean off the surface with a clean and wet cloth to have a shiny and new look to your outdoors.


You should follow these steps if you want to lay your porcelain tiles for outdoor areas perfectly. You can even hire a professional if you are unsure about your handwork.
