photo might help, but in general;
Yes start from the centre of the cooker hood and work outwards as thats most likely to be your focal point BUT you should dry lay out to check that it doesnt leave you stupid (tiny) cuts on either side, and then continue dry laying out to make sure the cuts...
Morning.
Use a plastic tile trim on the corner of the window reveal.
For the bath, make the boxing 10-12mm lower and bring the tile flush with the end of the bath. Baths move and tiles dont so bring it over the lip doesn't work well
silicone is perhaps the only option, looks like he used a bucket load of that at the bottom too.
The plasterboard should have been tanked before tiling, to be honest that whole job just looks like a recipe for leaks so i'd view any fix as a temporary one
granfix is a premium adhesive, no worries there. you'll have full technical backing. We specify it for very large jobs in brand name stores all the time. You can use grey behind the hardiebacker and white between it and the limestone to keep the cost down. Mapei certainly isnt considered a...
its not really my area, but watch it on chipboard if its the green 'water resistant' stuff. its waxed/treated and not a lot sticks to it - most addys require sanding it to get a key.
call mapei would be the best advice
you can tank the area, which is what i think your referring to, but be warned if you do use them in a wet area, you will have a hell of a job keeping them clean.

if your a competant diy'er you would probably be able to do it, but weigh up £180 against hiring/buying the kit and taking time off work etc etc - personally i'd pay the cash
It really depends on the adhesive as each addy manufacturer has their own guidelines.
Slurry coat is a common method for tiling low porosity surfaces such as when tiling over tiles or vinyl. Basically mixing priming agent (acrylic or SBR) with a few handfuls of your chosen dry adhesive to form...
not in a wet area, mould loves them...
tiling over can work IF the existing ones are solid and you dont choose anything too big, but usually your better off taking the old ones off
