hardboard splashback

[2020Tiling]

tiling a kitchen splash-back soon but where the extractor is there is shinny hardboard the rest is plaster , i wouldn't normally tile on hardboard but the extractor has already been installed, so can't really take it off and put up plaster board ,so was wondering if i would get away with priming the hardboard then tiling it ? tiles will be ceramic ?

It is compressed paper, you should not tile to it..

Hardboard will flex like no other, how big an area is involved

the whole area is 5 mtrs but the hardboard area is about 3ft by 2 ft.

Can't you use a fein or bosch 180 to cut it awy at the edge of the extractor then plasterboard it.

I would be inclined to replace with something more substantial
