When I worked for Topps I dealt with a few customer complaints which BAL took over. Although I don't know the outcome of them all I do know BAL did go to every complaint and did their tests and asked their questions and they got back with a report for each complaint.

So even if it's not down to the adhesive they're willing to help find the problem to get it sorted out asap.

To be honest from what I could tell, usually most of them were down to using the wrong product or applying it incorrectly, which really was down to the advice they got etc.

So yes, the guarantee's are good and they will sort out your problems if they go wrong in the guarantee life-time.

I know a rep at BAL who once had to go out with a Fein and re-grout due to simple grout discolouration when it states on the bag 'will not discolour' or something along those lines.
