Urgent advise needed on wall prep please

[Fekin]

Just need a quick bit of advise here guys

I've already had a thread about this customer.

Kitchen splashback, areas of wall in bad condition, ie, channels chiseled out for electric sockets and standard holes upto 30mm deep here n there.

I've already been down the route of it need repairing propperly, but now I've had a call from the customer to say the walls have been filled... either with polyfilla or cement, she didn't know which as someone has done it for her.

What I could do with knowing is, can this be tiled onto, it isn't massive areas, just channels up the splashback to sockets and spots say around 3 to 4" by 3 to 4" here n there.

And finally if it can be tiles over with say cement, how long at a guess is the minimum time before I could tile over it, and for polyfilla too if thats whats been used on the flippin walls, lol

Thanks for reading

Just had another call from customer, lol

In the kitchen theres an old fire place, in the fireplace shes got an oven there already and a hob to be fitted into the work surface inside the chimney.

Now the chimney has been boarded out at the front with thin plywood years ago, it did have a lerge thin metal sheet covering the ply to protect against the heat from the oven.

This sheetings now been ripped off, leaving the thin plywood backing blocking off the chimney and the gas fitter won't fit a gas hob in there because the backings obviously flammable.
She now needs this tiling but I think it is far too thin fto tile onto and as a hob needs to be fitted there might be a large degree of flwxing in the ply backing which would ruin any tiling and grouting, so im looking at replacing the ply backing with something stronger to tile too.

Since a gas hob is going to be close'ish to the backing thats going to be tiled anyway, do I need to use any special backboard, or will thicker plywood or plasterboard be ok for legal requirments ?

[Dave]

backer board and tiles will be fine.use flexi products.....tiles are fired at more temp than wot that hob will give them..lol.lol.......dave...

[Fekin]

Yeah I know, just I didn't know much about heat transfere

Cheers as ever Dave

Just be careful with the filled channels Fekin. Did a job last week and the sparky left it in a mess. Polyfila everywhere. Had to sand it down levelish as half off it came away when i touched it. It was plastered everywhere,on the sockets and everything.
