…. from a pile of slabs……. to a classy stone floor ….here’s how…
You need to decide beforehand on which widths you are going to use. Commercially available flooring in this pattern usually come in 3 widths; for example, 60cm, 45cm and 30cm. The lengths of the individual slabs will vary so that each width will have say a couple of rectangular sizes and maybe a square size.
“Sounds complicated?” “Not really, once you see a picture or two of how the pattern works, it all pretty obvious.”
…….so onto a few ‘Tips & Tricks’…….
- Sizing the Flagstones : This is perhaps the trickiest part of the job! There are no hard and fast rules—you need to assess what you have to work with and try and work out the best width options to choose—to achieve a pleasing pattern without undue waste.
- Essential Tools — Angle Grinder (preferably with a diamond/carbide disc), club hammer and bolster cold chisel, eye protectors, ear protectors and face mask, tape measure, T-square and marking chalk or pencil.
- Cutting stone with the grinder – make the straight cuts with the grinder steadily and evenly, letting the machine cut gradually to its maximum depth, around a few cms or so. It isn’t necessary to cut a stone “all-the-way-through.” Then with the bolster chisel inserted around the middle of the cut, give it a few sharp blows with the club hammer—and it should split away cleanly and easily.
- As you can see in one of the images above, I’ve angled the grinder slightly “off-vertical” — undercutting the edge. This is a little trick to make it easier to lay the cut edges of the flags closer to each other, avoiding the chances of odd lumpy bits left after breaking stopping the close fitting of two adjacent flags.
- Then carefully and gently tap along the top of the cut edges with the club hammer, chipping little fragments away to leave a more natural looking stone
- Finally, should it be necessary to remove some stone from the underside of a particularly thick slab, make a series of close parallel cuts, and repeat again at 90°, and then chip these away carefully with the hammer and chisel. (A great way, incidentally, to make your own stone dice!).
And if the floor is exposed to light and rain, then you’ll need to weed the cracks from time to time if they haven’t been grouted.
So give it a try and “Bonne Chance!”
