Bostik Blu Tack
Advantages: Re-usable and cheap
Disadvantages: Occasionally damages surfaces
Blu Tack is another household product where the brand name has become synonymous with the product much like Pritt Stick (glue) and Hoover (vacuum). I had to look up the official name to describe this and apparently it is a "reusable putty-like pressure-sensitive adhesive" (so there!). Many companies have tried to imitate Blu Tack and a lot of them do a pretty good job of it but in my opinion Blu Tack is the best because it is the most re-usable. A standard 60g pack costs about £1.50. You get two sheets of non-stick paper with a flat layer of Blu Tack between the sheets all packaged up in a cardboard box. Savour the item when it is flat like this because never again will your box of Blu Tack look so pristine. Of course all of the "fake" Blu Tacks are white in colour, but still get called Blu Tack because let's face it "reusable putty-like pressure-sensitive adhesive" is a bit of a mouthful!
The main use of Blu Tack is to be able to stick something on to something else without it being a permanent adhesion. So if you wanted to stick your Christmas cards up on your nice wooden door, you probably wouldn't use UHU glue (too strong and damaging!) or Pritt Stick (not strong enough), this is where Blu Tack comes to the rescue. It is like a piece of non-sticky chewing gum or putty that sticks to the surface and peels off easily without damaging the surface. However, be aware! The longer something is attached to a wall with Blu Tack, the more likely it is to damage the surface. I find after a while (few weeks) it has a greasy residue that comes off and would stain wood. Occasionally plaster may come off if you pull it off too hard too. I think it is when you leave it up too long, it goes quite hard rather than being flexible. However, for temporarily putting items on walls or doors, Blu Tack is great. I usually use it with card or paper but I have been known to use it to stick fairy lights round at window at Christmas and with enough of the stuff you can get them to stay up for quite a while, but obviously the heavier the item you are sticking, the more Blu Tack you need.
Once you have finished with the Blu Tack you can just peel it off and roll it up into a ball and usually place it into a drawer or more usually, place it back in the packet looking a lot less neat than when it came out. Of course being stuck to doors and walls means that it will inevitably pick up dust and dirt and the more you re-use the Blu Tack, the more dust and dirt you will pick up and the harder the Blu Tack becomes. All of this leads to it being less malleable and more unlikely to stick items to the wall. When Blu Tack gets to this stage in it's life you know its time for it to go to the big Blu Tack cemetery in the sky.
I think this is a very useful product and I'm not sure where I'd be at Christmas time or party time without it! For the price and the level of re-use you can get out of it, I would rate this highly and definitely say it has more re-usability than any of the cheaper brands. However, due to the occasional damage to the plaster and doors if left up for a long time, I'm taking one star away from it so just 4 stars from me.
Summary: Best reusable putty-like pressure-sensitive adhesive on the market !
