Mixing NHL lime mortar how to mix nhl 3.5 for beginners the easy way 

Haha A few of my videos I seem to get a call or message If I can help in anyway just ask Or whattsapp me pictures of your project I will try to guide you if needed

No problem I'm here to help

@@davidcongour61 mix it at a 1.2.5 structural mix at a 1.3 pointing Use a good quality nhl with washed sharp sand

Lol yeah it's to show the different stages of mixing I have a shorter video up 😜

​@@GMTpointingspecialistsltdlove the extended videos though! They give a more realistic idea of what it's like to be a repointing apprentice.

@@NAFO_Badger_Brigade I'm after an apprentice if you live near buckley 😁

Lol

It's true. I knew a man once who was happy in life, had a family, money and wanted for nothing. he was in as good a place in life as you could be....... Until the day he looked directly in to the mixer. I'll never forget that day. It was a belle with a Honda engine, petrol, mixed beautifully she did. One minute I was chatting to him about the weather, I turned around and when I looked back he was after doing it, he had looked directly in to it and from that moment his life was irrevocably changed. I tried to pull him away but like a dog with rabies he went for me,..... tried to bite my leg......... doctors did all they could for him but that man is now on the streets, begging for money so he can get his next sand and cement baggy for his mixer fix. He will never be right again. Some say that when he's really desperate he will even try using beach sand...... Makes me shudder to even think of it. So remember kids, when you're tempted to look in to the mixer, just say no!!

@@GMTpointingspecialistsltd free consultancy? .. I do have one question. I have a wall in the hallway of an Edwardian house which I’ve had to take all the lime plaster off. It was cracked and failing partly due to a WW2 bomb landing close and shaking the foundations. It’s the exterior wall which goes up the stair well so it’s 2 floors high so a big drop to plaster. Seeing as it’s the exterior wall and the wall is Flemish bond I thought that gypsum may cause problems over time for not letting the wall breathe. I was thinking then , instead of lime plastering the enormous was, instead to lime wash it with a watered down lime putty to soften the appearance of the brick and then to paint the lime wash with a good emulsion. I’ve never used lime wash or lime putty. As an idea do you think that lime washing an internal wall like that would be ok? Would I need any aggregate in the mix? Would it take ages to dry? I’m going to have to repoint the house in lime so I’m trying to keep the construction as traditional as possible without introducing too much cement or gypsum in areas I think may cause future issues. Any wisdom would be great fully received.

@@Scribe3168 hi I don't do lime plastering I only do the lime pointing If your on FB search in the lime There plenty of people on there that do internal work

@@GMTpointingspecialistsltd ok. Cheers for your time. I’ll have a look.

Yes NHL 2 or 3.5 You can do it in a hot lime depends on area you live in and how hard or soft your brick work is there's a few factors to take into consideration

@Rgeneb No mate, it's never had an Aberdeen number. I'm in North Wales 20 minutes from chester,and I've been here since 2004 If you need any advice on a project just message me

If you whatsapp me some pictures I can advise you a lot better Or take a bit of the original lime out Put it in white vinegar it will eat away at the lime and leave the sand granules

@@GMTpointingspecialistsltd Ah good plan. Yep I've got some sizable chunks of loose lime so I'll do that.

@alexbalrog where you are near wrexham borras sand, was mainly used a brown sharp sand mixed with soft

Its so each grain of sand gets coated with the lime And when you add the water it's so it coats the lime and sand so the calcification kicks in You leave it 10 minutes to fatten up It's good practice to thoroughly mix it

Gruelling!

The dry mixing is really important gets the lime coating the whole of the sand When you add the water and finished mixing let it sit for ten minutes then you can use it

Yes just mix it in a cup But give it a good mix while it's dry Add as little water as possible and give a good few minutes while it's damp

You can use a rough sponge Wire brush White vinegar or a light acid But becarful not to get it on the pointing

@@GMTpointingspecialistsltd thanks for the advice. I'll give it a go.

Yes it is saint astier and lafarge are the best in my opinion I mix at a 1:3.

@@GMTpointingspecialistsltd Thank you. I live in the Cotswolds and so the stone work it soft. I was just told i would be better with NHL 2

@@chrissmith841 yes NHL 2 has a higher free lime content if you use a good quality one

@NAFO_Badger_Brigade that was a slip of the tongue I couldn't edit it out. For some reason, over 50000 people have watched that video, and you are the first to notice It was 1 lime 3 sharp sand

@@GMTpointingspecialistsltd I'm Ur virtual apprentice!!!!

@NAFO_Badger_Brigade that will do. If you have a project you want me to talk you through just send me a wattsapp and I will help

@@GMTpointingspecialistsltd Cool thanks - I will do.

No problem I'm here to help

Hi yes you can as it's inside use a NHL 2 or 3.5 Or a putty what ever is easier for you to get

@jimmymcmenemie1427 yes hydraulic nhl means natural hydraulic lime Hydrated lime is a plastasiser for cement Sorry I 'm shattered playing international pool in malta atm

Hi yes depending what your data sheet says on the lime your using try to use a good quality nhl It's 1:3 or 1:2.5 When using lime the binder always goes first And mix by volume not weight unless the data sheet says other wise

What’s the binder?

@@GMTpointingspecialistsltd thanks for sharing all this information!

@@ellenphelan6475 the lime is the binder

@@ellenphelan6475 no problem if you have any questions feel free All I ask is people to subscribe

September is ok to point Use a good quality lime Lafarge or Saint astier I use Use a soft and grit sand together Well mixed If the brick work at the bottom under the render is fine just repoint it if not lime render it Make sure you cover your work with damp Hessian And use not to wet a mix as it will dry and shrink on narrow joints Dampen the wall before you start to point and work from the top down pointing in the rain as long as it's not landing on your fresh pointing is fine I just work under a sheet Hope I've answered all your questions

@@GMTpointingspecialistsltd Thank you, that's great! Really appreciate the advice.

Brilliantly done very informative

I prefer a bell mixer as it's lighter for me to get in and out of my van

Hi if you check the data sheet it always says mix by volume Just put hansons data sheet in Google I use lafarge or Saint astier much better product You will get people saying nhl is as hard as cement only use hot lime I dont do tuck pointing I don't get asked for it Join the fb group the fine art of repointing

@GMT Pointing Specialists Ltd Much appreciated. What's better in your opinion about the lime you use? Yeah, I certainly don't want lime to be hard as cement as my bricks are soft red rubbers. Perhaps I'll mix 4:1 to keep the mortar weak. Facebook group joined much appreciated.

@plummetplum lafarge and saint astier have a higher free lime content less clay content If you can use a nhl 2 that's higher free lime than nhl 3.5

If your a beginner I'd say an NHL 2 or a 3.5 Depends what's local to yourself Or if you can get a premixed putty That will be easier just tip the water out and mix you can choose the colour of putty you want as long as your walls don't get hit with 80 plus miles an HR winds

@@GMTpointingspecialistsltd thanks by nhl 2 or 3.5 is that the lime type 😊

@@jacobbenger-pereira3514 yes that's powdered lime I use lafarge or saint astier as it has hi free lime content mix at 1 lime to 2.5 or 3 sharp sand read the specs of what lime you use and what you can get local

@@GMTpointingspecialistsltd your a beauty! thank you man !

Hi sorry to bother you on a Sunday trying to get the lime sorted is Hanson lime hydrated ok to use . Hope your having a nice weekend

Depending on the time of year it's about 8 weeks at the moment Keep it covered as long as possible This weekend is supposed to be a hard frost so would need Hessian sacking Bubble wrap or tarpaulin sheets

Hi yes you can use a hand mixer Just make sure each particle of sand is covered with lime before you add water Backfill push small stones into the backfilled lime it stops the lime from cracking and you don't use as much lime

Love your channel. What ratio would you recommend on a 50’s semi? Originally done in lime (bright white) and redone over the years in Portland

@@jmabarker1 the ratio on the data sheet of most bags of good quality lime is 1:2.5 I do a 1:3

@@GMTpointingspecialistsltd thanks. Just had an agent from Conserv tell me their stuff is pre-mixed and ready to use with the addition of water. Does that sound right to you?

​@@jmabarker1 I have just bought some Conserv NHL 3.5 material. There is a large bag of grits/gravel/sand substrate with a smaller separate sealed pouch of lime inside too. You mix the contents of the lime pouch into the substrate, add water, and it's good to go. All the proportionate and relative quantities (ratios) are are pre-defined at the factory, so I am going to accurately measure one fifth of the lime (by weight) into one fifth of the substrate (by weight) at a time, simply to 'batch' it into smaller 5 kg hand mixed quantities. You could batch it down to 1/4, 1/3 or half, just keep the proportions correct.

Yes sand is prewashed before it's delivered Mix usually takes 30 minutes Years ago the would have had one or 2 guys doing a mix But back then they used hot lime putty type material with ash and charcoal even gypsum straw in the mix Still much better than cement though lol

Yeah there's always several ways to do somthing I just wanted to show To use a small shovel Not to grip the handle But main thing is stop the mixer So no risk

Inside is different you use a softersand The wetter the mix more chance of it shrinking I work by myself so it's not quicker for me to use a gun I've done it 25 years 5 different types of pointing guns I still do it by hand the reasons for this is I use a dryer mix I use a mush sharpersand so won't go through a gun the sharper the sand the more it allows watter to wick away You get a neater finish And less shrinkage

@@GMTpointingspecialistsltd , Cool, I try to stay away from pointing jobs, especially strap pointing like we have a lot of in Yorkshire. I take my hat off to you fellas who like doing it. Just checked out your video because I have just quoted to lime point a garden wall and rebuild another. I was double checking to see if its Hydralic or hydrated lime to quote for, haha, 30 years in the trade and used lime twice.

@@chrisbow1776 hydrated now a days is just used as a plasticiser for cement on newer bricks If it's old bricks hand mades always use a hydraulic or hot lime used hot or cold

You would have to use a washed soft sand It won't be smooth it will be slightly stippled as you don't want a skin on lime If the joints are wide you need a sharp sand What project are you doing

@@GMTpointingspecialistsltd that's brilliant I've been a site brickie for over 30 years but my back gone I've started doing pointing jobs I've done a few with nhl 3.5 but it's. New learning curve for me

Many thanks for the reply

@@timclarke1791 any questions just ask or any videos you want me to put up just let me know Just choose your NHL well there's good and bad NHL 3.5 on the market

@@GMTpointingspecialistsltd that's brilliant would love see you pointing with nhl and washed sand .. I use saint astier 3.5 is that good stuff

It depends If your in a protected area you can use a hot lime or a putty If not a NHL 2 or a 3.5 On tight joints make sure you keep it damp for a few days Never use any cement on accringtons

Hi, What sand should you use on Accrington's , Thanks @@GMTpointingspecialistsltd

@mickeytherye hi I use a brown grit sand It compacts perfect If you look at one of my videos on different sands

I have never done a swimming pool this is lime 1-3 3-1or 4-1 is cement based you would need to talk to someone that does that type of work to find out the best mix to use

Is it a putty that it's premixed with

@@GMTpointingspecialistsltd its in a jumbo bag your just chuck straight into mixer and add water

@@GMTpointingspecialistsltd its all sealed its 450 pound for a jumbo bag

@@kierenboimufc5940 I'd find out what lime it is first sounds like a NHL Then if your adding water If your bricklaying with it you wont be able to go as high with it in a day like cement bricklaying If your pointing with it I'd of got it in smaller bags if you were going to point As how can you know what consistency it is Or if they have used a good high free lime content NHL I always mix my own so I know what ratio it is

depending on the stone yes You can use a NHL putty or a hot mixed lime Depends on weather and location I'd personally never use putty or hotline in a bad weather area

I'm using lafarge nhl 3.5

Its means the strength Nh2 has high free lime content, and 3.5 has as well if you use a good quality one Saint astier or lafage 5 has more clay I never use nhl5

Yes thanks I could of put a sheet down but it didn't splatter on to the road as I normally do a dryer mix It's for begginers so tried to keep it simple All input is good If you have any videos put a link to it on a message so people can have a watch Thanks

Can always use a dustbin lid to stop splashes

@@markanderson6969 yes you can the old rubber bin lids were the best or o gorilla bucket but if you mix it properly it won't splatter If it does wash it straight away it won't stain

Thanks new to all this RU-vid stuff I prefer to be behind the camera I'm from North Wales not far from Chester What area do you cover

@@GMTpointingspecialistsltd I’m literally on the south coast near Brighton A lot of salt in the air around here. You have a new subscriber mate

You're a good bloke. 👍

1 : 3 I use for lafarge nhl3.5 You can do a 1:2.5 depends what your doing What ever make of lime you use just go on Google you can download a free data sheet It will tell you the free lime content and mix ratio Hope that helps

@@GMTpointingspecialistsltd Thanks mate. Just for repointing a sandstone cellar wall which let damp in recently. Wet lower to the ground.

Yeah I was given it to try I've used a pointing hod for 25 years so I prefer to use the hod as it keeps the moisture in the mix the pointsman I didn't like very much tbh

@@GMTpointingspecialistsltd its ok for weather struck because of the lip but they are expensive for what they are

@@kierenboimufc5940 yeah thought I'd try it f But I work with lime so I don't do wether struck If you have any videos feel free to put a link

Ive seen somewhere on here but this was years back. Your work looks really nice i would like to to more of the historical work but at the moment just currently doing house bashing

@@kierenboimufc5940 thank you I've only just started doing the videos on here I normally just put them on my FB page But I will start adding more soon

Hi there's different quality of lime The lime I use is mixed by volume just download the data sheet it's free on Google It's 1 lime 3 sand always put the binder first (lime) Lime burns so be careful use PPE

Yes, you probably watched the guy with the dreads 😃 same as me and I had your question.

It by volume just read the data sheet Lab testing to see what the strongest possible strength you can get from lime is done by weight as they use a powdered sand and a different type of sand So people who think NHL is to hard at 9 mpa or newton's that's not what we get when we mix on site strongest is about 5 mpa after 200 days

@@GMTpointingspecialistsltd Thank you! I've watched a dozen or more videos and yours is the first one that actually said look at the data sheet! Thanks again you solved my mystery!

Yeah I said 1 1 3 It's another lime I put in that was a slip of the tongue I always try to say the binder first but its hard when I talk to people like yourself I do a mix standard 1 hydraulic lime Nhl 2 or 3.5 lafarge 3 sharp sand or a mix of sharp or soft must be washed no building sand I also do a 1 1 3 mix It's a 1 hydraulic 1 putty 3 sharp sand I must of edited that bit out as I just wanted to keep it as simple as I could I did another video on mixing hydraulic lime If I say 5 1 1 and put the sand first I'm talking about cement mortar 5 sand 1 hydrated lime 1 cement 4 1 1 or 3 1 1 there is too much powder to the sand I'd never mix like that Any questions just message me I'll help you out

What do you mean talk to people like myself, and what is this other lime you put in as well, i,m not criticizing i thought the video was very informative its no good doing a training/information video if you don't like feedback if you were in front of trainees/students would you not ask { any questions } .

@horserider9578 people like yourself that say sand first not binder first And don't mind people asking questions that's the whole idea of my channel

​@@GMTpointingspecialistsltdwhat is the purpose of adding the extra free lime?

@Smuggler300 as the sandstone was very poor in places, it softens the compressive strength of the lime

Always read the data sheet on what lime you use Normally a 1:2.5 or 1:3 NHL 5 if it's in a high wind heavy rain area or if not you can use a 3.5

Always use a washed sharp sand you can compact it back well and it lets moisture in and out

@@GMTpointingspecialistsltd it’s north east scotland so nhl5 1 sharp sand 3 building sand and one lime I was recommended.

@@shaunstewart5400 not building sand to many impurities Read the data sheet free online It will probably say 1:3 sharp or grit sand You don't want to lock moisture into a chimney and that's what building sand will do Search lime suppliers near me and they will tell you what local washed sharp sand is the best for you to use

@@GMTpointingspecialistsltd ok what about the mix ratio what would be best then ? Just all washed sharp sand yes?

Never had a problem with a bell mixer And I mix on site have you tried picking a forced action mixer up and putting it in a van At the end of a long day Belle mixer £300 to £400 Forced action mixers £2500 to £3500 Massive difference in price These videos are for beginners

@@GMTpointingspecialistsltd yep I use a baten to roll it up. I suppose it is a specialist bit of equipment. Not everyone's cup of tea.

@@benweaser9901 I had a Barron was really heavy when I do big jobs and I can secure it on site I use it but small jobs like this I use the belle mixer And like the video says it for beginners to show them that lime takes a while to mix not a couple of minutes in a bucket

I dont really understand that comment

@@GMTpointingspecialistsltd Meaning it takes a long time to have ready to use when you grew up around cement/concrete. BTW that was a very good video. Thank You for sharing and teaching.

@normhowes2975 yeah the video was to show it take 25 minutes to mix but you can do other things while it's mixing Thanks for your kind words

Ok can you recommend one that's cheap as I do this free If you press cc on the video it puts subtitles on it gets 95% of the words I say lol

​@@GMTpointingspecialistsltd Boya BX-XM6 wireless mics.

@onanysundrymule3144 OK thanks ill have a look at them

Yeah bad for lungs and eyes

@user-dx2td9ft6p totally disagrees if you read the data sheet it tells you Just because you do it that way doesn't make it right All my videos are for teaching beginners, so I'm teaching them the correct way
