fischerInjection Mortar FIS P Plus 380 C, Polyester Resin, 522178

Of course this is used for wall anchors, but it's just an excellent masonry repair filler and glue.An example is that I used it once on engineering brick, where the entire face of the brick I was drilling though blew out and shattered. I stuck it all back in, using the Injection Mortar like glue, and it's been there for, oh, five years now.It's fast setting, strong and completely weatherproof.For anchors, you are supposed to drill a few mm larger than the threaded bar. Blowing the dust out is important. You can make a better bond by moving the bar around a bit to ensure that any remaining dust in the hole is absorbed in to the resin.I will often use masking tape. Putting a little around the hole and some on the bar if it needs to be neat and if you don't want to get any on the bar threads. Have a cloth handy to remove any spillage.I always have to think ahead, how it will be held in the right position while it sets. Often that is just offering up the item you are attaching to the wall, setting everything in position, then firing the glue and then the pushing the bar through the fixing holes and in to the masonry. Sometimes that's not possible and you can just use a set-square to hold the bar in place until it sets. It only takes a minute or two. Just wait until it starts to set.I tend to wait about 90 mins before I do the nuts up, and 24 hours before I put the final torque on them, but I am probably being too cautious.Buy some extra nozzles. You will need them.Highly recommended.

Will buy again, easy to use and really strong.

Reviewed @ 4 due to the description... Description said it would fit any filler gun...This tube was too chubby; bought the Normal skinny one and it works a treat...The product is a 5 ...the seller's description is a 4

Great stuff! it does harden quickly ,so you need to plan out your work before application.

Ive bough a bunch of these to anchor M12 bolts for my timber garden office construction to the concrete base they are rock solid and I'm delighted with the resultNote: They came with the mixer nozzles

The description said it fits one, but it doesn’t. The back part has to push in a donut shape, because the centre doesn’t move forwards as it pushes.On the plus side, it comes with 2 tips, with is also not mentioned. 12h later it wasn’t fully dry and did not meet expectations, but that could be due to the application issues i had.

Works well and as described to secure studs into masonry.
