Bostik Gripfill 350ml Grab Adhesive Box of 12

I've used this since it first came to the market (in the 80's) since then another type has turned up (this is the original stuff)First off this really does work. I've attached sinks to walls, stuck floor tiles down with this and hung wooden shelf brackets up too. This is the normal adhesive version and is suitable for porous and non porous application. There is another version which can be used only if one surface is porous (Gripfill Solvent Free) and that one has a much milder smell but is effective esp when wood is used.I would recommend this type for tougher items that need securing but would caution on a few areas. Firstly this sticks very firmly so make sure you won't want to move whatever it is you are fixing as removal could pretty much destroy the item (it sticks that well) the other point to note is in some cases you might be better off looking at the solvent free option esp if you are fixing wood be it skirting boards or joints (or the various other options such as no more nails and equivalent products). This original one though is the champ for sticking thanks to the strong adhesive used, but there is quite an odour off of it until it's cured.Do note that this is "flexible" where as some adhesive offerings are not this won't snap or crack so use it where some movement or strain might occur (for skirting this isn't going to move so use the water based adhesives there)As a side note whilst this is great for fixing plasterboard I wouldn't recommend trying to stick heavy items to plaster board with this, purely because unlike a "solid fixing" this sticks to the surface (which is fine if it's a normal wall) the surface of plasterboard though won't hold heavy loads but it can be useful in other areas as an additional adhesive (I've put bathroom units with fixings and this to help with extra bonding) Thanks to the gap filling properties this works a treat on many areas where you need a fix "and" to fill gaps hence the name, it's really extremely useful to have around. Working with gripfill is fairly straight forward but I'd be somewhat less generous with application so cut the top to a small point to give a moderate flow of the adhesive don't over apply. Also avoid contact with clothes once this has set it's difficult to remove easily.I've used this for many years and certainly has a place in the house/shed for various jobs.
