how to remove nibs from paving blocks?

[Harold Davis]

Hi,

What's the easiest reliable way to get rid of the nibs that stick out from concrete paving blocks?

I'm considering using blocks that are 200mm x 100mm x 50mm - widely used in block driveways, coming in yellow, pink, grey, etc. - to make the outer edge of a hearth. The show surfaces need to be flat.

I don't think an angle-grinder would leave a flat surface. Would a hand- held carbide file do the job?

Thanks in advance!

Even if you grind them off, they will have a different surface texture and look awful. Think again for material sources I reckon.

Couldn't the right kind of sealing deal with that?

Yep, don't think they'd look great indoors, when cutting them you usually reveal more aggregate than is visible on the surface.

Try one, dip it in mud, wipe it off & see how it looks. I'd probably use an angle grinder.

It sounds an awful lot of work with unknown result.

I would get the bricks / blocks I didn't need to modify. How many are we talking about?

Yes, on consideration I think you're right. We're talking about 3 linear metres.

I would look for a matching kerb block and use that along the edge.

I presume 15 blocks? Plus spare and for corners.
