Must admit I haven't really got the hang of getting customers to agree to test areas being done. It's not always as straightforward as it sounds - there is a big conundrum here!
The biggest obstacle is if you are looking at quite a neglected floor, there's no point doing a test area up a clean corner... you have to do it in one of the worst bits to show how it'll turn out. So then you have to ask the customer if you can make a nice shiny clean little area in the middle of their otherwise shabby-looking floor. A lot of people have a problem with that! They don't want visitors coming round and seeing it like that.
As it is only at quote stage they obviously have not agreed to having the work done so they could potentially be left with it like that, if they don't accept the quote... I know the point of this is to secure the work but they don't want to feel obligated into accepting the quote because it (in their view) will be the only way of getting rid of the clean patch in the middle!
Also... depends on what type of floor I suppose but in some cases if you put a sealer on just a test area is there not a chance of never getting that bit looking exactly the same when you do the whole lot? I'm thinking of "Enrich n Seal" here, which cannot be fully stripped out once cured, according to the labelling.
I know it's a different thing but I did a metre square test area on a vinyl composition floor in a working men's club, cleaned & applied several coats of topical sealer as you do... they accepted the job and when I was finished you could still see the test patch! Bit embarrassing, that! I had scrubbed and stripped over the area really well but it just did not look the same.
I know some stones will not have this problem but I'm thinking more towards limestone hone & seal kind of jobs... it's quite a worry, when you've had your fingers burnt in the past!
Any tips Kev?
