Tiling Onto Hardboard

Hardboard is really a little too flimsy to tile onto. You'd be much better off using 1/2" ply or MDF.

Thanks for the reply but in this situation ( 4 foot long x 3 1/2" wide strip) I think 1/2" ply or MDF would be overkill. I can go purchase 3 or

Cheers

If your 4 x 1 uprights cover the whole 4ft length, you'll have 2 edges to stick the tiles to. You may not need anything across the top, but it's a nice little ledge for glass bottles and things, which will crack the tiles if dropped. Hardboard is really no good at all but I suppose you could glue 3 or 4 pieces together if it's quicker than going to B&Q

I would normally fake that up from scarp cip.pluyy, bits of old kitchen units and spare bits of MDF, or even plasterboard.

Hardboard never. No stiffness. The tiles will crack off.
