I have used pointing guns for brickwork and patios they are ok but still time consuming refilling. For patios you could try ready mixed brush in wickes do some it is expensive but is so easy and has resin built in and very esay to work with will take you so little time it is the bees knees

I've used both guns and geo-fix. The guns are quite time consuming as you have to keep filling them up and they tend to get blocked quite easily. The geo-fix works well but after a year or so there will be moss growing from the joints. I have pointed a lot of patios and tried different methods but still go back to trowel and jointing iron.

The Guns which are like oversized silicone guns are great providing you get the consistency of your mortar mix to be perfect.

I would advise using more mortar plasticiser than in a usual mix. with a pointing gun you will probably exceed your current pointing time by 500%. they fill gaps so much easier than with a pointing bar.

Dont be bothered about over filling and it coming out of the joint, just wait till its drying and bar the mortar in as usual then scrape the excess away to reduce staining chances.

The pointing guns which use a compressor arent much good if you ask me, their rep came out to meet me after I said I could do it faster with a silicone style gun and I did.

Slightly bare information but I Hope it helps, in short there definatly better than the traditional bar.

You have had some good answers, I have used the skeleton gun type, we found that you need good fine sand, with extra feb than usual, always have a screwdriver in your pocket to unblock the nozzle, as they do get blocked quite often.
When refilling always clean out the last bit of mortar as it does dry out stiff.
For patios the better gun is the Point Master, it has a larger 10mm slotted end, same size as perp joints in brick work, and doesnt block up.
These guns are heavy when filled right up.
Being a traddional builder I much prefer to point by hand, ie, bucket hand or small tool.

Hi. I always use a jointing compound called Geofix, its available in buff and grey. Open it up, sweep it around the paving and point it up with a jointing iron, simple as that. It saves a ridiculous amount of time and it doesnt stain the paving like the more traditional methods. Drawbacks are that it can go off very quickly in warm weather making it hard to sweep around and also that it costs around £30 a tub covering about 12 square metres. Its definitely worth it though, saves you hours, perhaps days in labour!!

They are aimed at the DIY market and are a waste of time.I point up as I go and then you dont have to go back over it when the slabs have been laid.After 30 years doing it this is more cost and time effective.
Regards Doug.

geo- fix by everbuild tidy as any thing and setts like iron try and you wont look back .

hi there are 2 types of gun for sale in screwfix ,the dearer one is better quality ,you do have to make the mortar quiet runny to get it to flow out of the nozzle ,,but you must make sure it is cleaned really well after use,once you get the hang of it it makes pointing much cleaner and quicker hope this helps ,brushing in a dry mix is also quick but it stains the slabs and tends to crack and leave voids in joints

I have found it depens on who supplys your sand and the quality of sand they stock, otherwise they just jam-up, i find it quicker and more efficient to do it with a jointing iron or pointing trowel.

We have re-pointed brick work with guns before and found that it speeds up the job but the mix has to be right otherwise the gun will just push out the water from the mortar jamming the gun.

Personally I can't stand using guns I've bought 2-3 over the Years but apparently if you get used to them and the right mix to use they are good and I've seen people use them effectively but there just not for me I mostly use easyjoint... Something that would take a day to point can be done in an hour I know its expensive to buy just remember to keep beds full so you don't loose too much compound. Tried it once and never gone back

The guns are very time consuming. I would use a traditional pointing method.

Guns are no good because after putting it in with a gun you still have to trowel it up so its no quicker a proper pointer would never use one its done in the same move put in pushed back and troweld

Pointing guns are handy for small areas but they block up a lot, I like the old fashioned hawk and pointing tool Method but also the newer brush in compound is good and a quick method

For standard bucket handle pointing I would always use a pointing gun as you'll save alot of time but be sure to buy a seived sand like rock common so the gun sees the block.
I'd also highly recommend faithless guns. 👍

Pointing guns take too much time up and mix has to be spot on inside them for them to be decent, brush in grout I find the best aslong as you compact properly you get no come backs 👍🏽
