Me and my tiling partner have travelled the length and bredth of the country from Middlesborough to Canterbury doing changing rooms in new Gyms for a local contractors.
The walls are easy work, sometimes in excess of 500 sqm all 6 x 6 white tiles 2mm spacer, 6mm trowel with bucket addy straight onto new studded moister proof green plasterboard walls...don't forget to fill the board joints with addy on the back of trowel...
Aim to
tile and grout 100sqm a week to make a decent wage after taking out hotel, we always stayed in travelodges (booked early enough you can share a decent clean room for around £twenty per night £tenner a piece), and travel time and costs.
Cant emphasise enough the use of a laser to mark a datum line and make a staff to guarantee lining adjoining rooms up as putting on battons with a spirit level over 500 sqm just will not work no matter how good a level you've got.
Speed is the name of the game on these jobs, get the pallet of tiles and addy in the middle of the room your tiling, so to avoid wasting time carrying buckets and boxes all over the site, keep
tile cutter and ruler to hand and get a pouch for your spacers, wedges and pencils and markers, anything to avoid wasting time as its all about the meters per day.
Set a target for the day, and don't go back to hotel till you've hit it.
I'd say its best to have at least two of you doing this kind of work as some days it pays to let one do the trim work round doors and corners etc while the other bangs the tiles on and keeps your meterage up, also nice to have someone you get on with to have a pint and something to eat in a strange town after a long day...oh and don't have too many pints and end up going on the lash... you'll end up spending all you've earnt that day.
We always had one good booze up at end of job to celebrate finishing.
We always measured up at on a Friday afternoon and by the following Friday the cheque was through the letterbox, that way your only a week behind with pay...
