How to lay sandstone patio slabs

Let's look at a step-by-step of how to lay sandstone patio slabs.

1, Choose Your Area: The first thing you'll need to do is decide where you want to lay your sandstone pavers. This area should be level, firm, and have good drainage. We recommend marking the area using some spray paint.

2, Start Digging: Using a small shovel or your hands, start digging until your sandstone area is 125mm deep + the depth of the pavers. When finished, your area should be about 150mm deeper than the surrounding area.

3, Level It Out: Create a level plane using a rake and string line. Once you have a level space, you can compact the area using a tamper or garden roller.

4, Fill In The Sub-Base: You'll want to provide some sub-base beneath the stones for better hold and drainage. We recommend using a mixture of crushed stone and dust, filling and compacting at least 50mm.

5, Wash Your Stones: Remove any dust or dirt from your stones with some water.

6, Prime Your Stones: Using fine mortar slurry or a proprietary priming product of your choice, prime the backs of your stones.

7, Mix Up Your Mortar: To create your mortar mix, you'll use one part water and cement and four parts sand. To make sure you can work with it, your mortar mix should be a “wet” consistency.

8, Spread It: Take your mortar mixture and spread it evenly across the area that you just dug out, and use a roller t level it off. This should fill out another 30mm of your bed.

9, Lay Your Stones Down: Lay your sandstone units down. You'll want to make sure that they are around 8-10mm apart from one another. To make sure they are firmly locked in the bed of mortar, you can use a rubber mallet to tap on the stones lightly.

10, Fill The Joints: Next, you will want to take your mortar mix and fill in the joints using a trowel. Again, make sure that your mortar is “wet” in consistency so that you can work with it. You can then use your pointing tool to compress the mortar mix.

11, Allow It To Sit: Before walking on your sandstone, allow it to set for around 24 hours at least. If you live in a wet climate, you can allow it to sit for a bit longer.
