How do I open the bottle? I've tried cutting, piercing, everything... Can't get it open!!

People could be a little less patronising, some of us don't have an much knowledge of /have never before used hardware tools and products as others :)

If need be, can it be sanded?

It doesn't really need to be sanded as it has quite a smooth finish. Just squeeze it into the gap and with a slightly damp fingertip, smooth it out. I always have a damp cloth to just wipe off any excess that goes somewhere I don't want so I don't run into the problem of needing to try and sand it. If you have gaps between the skirting board and wall (like some of mine have), it's great for filling these in, but I always make sure after I have run my finger over it to wipe off any excess that may go up the wall a bit so it doesn't leave any sort of ridge. As it has some flexibilty I find that if you try to sand it, it tends to ball up a bit. Hope this is of some help. Noelene

Can i use it to fill in between liner paper as some of it has gaps in between liner paper.

Caulk can be used for all D.I.Y and decorating tasks, great stuff for filling all gaps,holes,cracks, can be painted over, no problem. Hope this helps
