How to Install
Laying porcelain pavers is really quite straightforward. Although these 24” x 24” pavers weigh 36 lb., that’s a lot lighter than equivalent sized concrete pavers, so they are much easier to handle and accurately position.
Here’s how to lay them in three different applications.
Over existing concrete
Because of their strength, you can lay porcelain pavers over solid surfaces supported only at each corner, essentially as a ‘floating floor’. So no adhesive or thin set is used. The pavers must be raised a little since you need to avoid any rocking of the pavers due to minor unevenness or cracks in the concrete slab. Our HD-PAD10 3/8” high rubber pads, with their inbuilt spacer tabs have been specifically designed for laying porcelain pavers over concrete. The rubber composition offers excellent sound absorption, making them quieter when walked on, and since rubber has excellent frictional properties, it stops the pavers from moving.
To lay your pavers, firstly place these rubber pads on the concrete slab approx. 24” apart in a grid pattern. Then take your first paver and place it so that each corner is resting on a pad and positioned tightly against the spacer tabs. Then take your 2nd paver and lay it alongside the first paver, again with all four corners resting on rubber pads and the paver edge hard against the spacer tabs. Then just continue laying the rest of the pavers the same way.
In some places you might need to place a thin rubber shim between the paver and the support pad to stop the paver from rocking. For this, either use our HD-SHIM2 1/16’ thick rubber shims or simply get a small sheet of rubber and cut shims to suit.
And that’s all there is to it. You don’t need to fill the gaps between the pavers with grout as they are left open. Apart from the cost saving, this offers the bonus of letting water drain away quickly under the pavers.
Maybe you’ll need to cut some pavers for the final row against a wall. To do this, you really need to use a wet saw. You can generally hire this equipment from a hire shop but if you’ve only got a few tiles to cut, we suggest you talk to your local tile shop who would hopefully be prepared to cut a few tiles for you at a modest charge.
Over sand or gravel
Laying porcelain pavers over sand or gravel is just as easy as laying them over concrete. But you do need to make sure the surface is well compacted and as level as possible.
Essentially you lay the pavers in a similar manner to laying them over concrete except instead of using rubber support pads, you use plastic tile spacers between the pavers. Whilst you could use spacers purchased from any hardware store, you’ll achieve a better result by using our specially designed SPACER . The main advantage of these spacers is that they have a small round plastic base, and the corner of each paver sits on this plastic base ensuring where the corners of four pavers meet, the top surface of all the pavers will be perfectly level with each other.
Stepping stones in a grassed area
Although you can lay porcelain pavers directly over grass, it’s always better to remove the grass where you want the pavers are to be laid as well as removing a shallow layer of topsoil. This guarantees better stability of the pavers. For the best results, proceed as follows:
Lay your pavers over the grass in the final positions you want and mark the outside edges of each paver with a spade. Remove the pavers and dig out the square(s) of grass plus a layer of topsoil to a depth of about 2”. Partially fill with a layer of fine 3/16”-1/4” gravel and compact well. For easier levelling of the pavers, we suggest you also add an extra 1” layer of sand, but this is optional.
Carefully lay the pavers so they protrude above ground level by about ¼”, tapping them carefully with a rubber mallet so they are bedded properly. They must not protrude above the lawn level as you could damage your lawnmower blades.
