Marshalltown The Premier Line GB692 12-Inch by 24-Inch Vinyl Grout Bag with Metal Tip

I'm a bricklayer and have tried almost every tool for repointing available but always come back to the 'icing bag'. This is my second one which will replace the exact same model which I've had for 10+ years.Some bad reviews point to the fact you need the mortar mix to be very wet, but this is the case with all repointing tools. The key is to mix the mortar in small batches, thoroughly mixing it dry before adding water. This helps to avoid any lumps which will clog up the nozzle of the mortar bag and make the process highly frustrating. I recommend using a drill with a cheap mixing paddle attachment in a standard bucket, mixing no more than half a bucket full at a time.You're essentially trying to push a coarse sand and cement mix through a nozzle three times the size of the centre of a Polo Mint, so it's never going to be easy and need to manage expectations accordingly. You need to fill the mortar bag no more than 50% and use the remainder of the bag to 'tie up' and put enough pressure behind the mortar mix for it to work. It's tiring on your hands but fairly easy to control once you get going.In summary; not the easiest to use, but a tried and tested tool which is often preferred by professionals.

This is great for pointing brick slips just make sure no small stones in the sand

Very good quality, reasonably priced

I bought this thinking I might save some time pointing brickwork. The bag is very robust with quite a large capacity but after some experimentation I reached the conclusion that It only works on condition that more than the recommended amount of plastisicer is added to the mortar and excessive water to produce a mix with the consistency of toothpaste, both of which will weaken the finished mortar. Reverting to the old trowel and tuck pointing tool it is easy to see why these aren’t used by professionals

Not fit for purpose... if you're a contractor, avoid.. I had 14m x 2m wall to repoint... I knocked up the mortar with a mass of plasticisor so it was fluid/runny...nozzle blocks frequently and its incredibly messy.. if you hold the bag perdicular to the wall it just drips out the back end of the bag..Complete rubbish...

How did we not use them years ago .The way we use them for pointing brickwork is to mix a 4 plastering sand, 1 cement, 1 lime, plasticiser, the mix has to be very wet so the mortar runs out the bag /like a grout/ we don't use the metal tip.To use full half way or less , and pipe in ,over full joints and point.

Brilliant bit of kit . Just make sure the mortar is clear of stones

When I first bought this the material was thick and lasted longer but the last two times I had these they were thinner material. Didn’t last a week for my job
