    Agreed, it’s just one of those jobs where there’s several ways to achieve the same result, depends on your own preference and materials to hand

    I do read on the forum that spray foam seems to be gaining popularity also as an adhesive, not soley as a gap filler

    From fixing plaster board, skirtings and several other areas, including injecting up peoples bottoms in prison :eek:

    Although that last use could be argued that it’s a gap filler not an adhesive ...... perhaps .... dunno

    Thanks chips

    Always use sand and cement tap it with a hammer get it to whatever level you want . Let it set a bit. Drill and plug it.

    Plasterboard adhesive works very well.

    Hate when boxes have been set with cement. So hard to remove / adjust later on. And a pig to chase in a spur. Please, just use bonding. Cheap, easy to get, fills large spaces, dries quickly

    Seen plenty fixed with expanding foam. Seen plenty fixed with gripfill too.

    Cant see any problem at all with using foam.

    Used right foam is a superb fixer, filller, insulator etc.

    Use a gun, set it right and you will be fine.

    When using foam I've found its best to place the can in the hole to be filled. Stab it quickly with a screwdriver and then run as fast as you can! :D

    Using bonding, board adhesive as long as the box is fixed to the brick and make sure you stop AIR being able to get drawn into cavity if dot and dabbing .
