Finishing lime mortar off using a piece of wood, then a churn brush 

Thank you any other videos you would like just ask I will see what I can do

Thank you for your kind words much appreciated

Thank you for the compliment it means alot , Soak the wall before pointing ie with a hose pipe if you can and then after you have repointed it mist it over as often as you possibly can for a minimum of 3 days for this time of year if your pointing in a windy area cover it with a sheet as the breeze will dry it out alot quicker

He said he used NHL3.5 on this wall

Please feel free to subscribe it helps getting my channel out there Depending on the temperature I would keep it on 5 days dampen the Hessian each day If it's hot the next day if it's gone of hard enough soak it two or three times a day with a hose pipe You want it to slow set The slower it sets the less chance of it cracking and drying out too quick Hope that helps

@@GMTpointingspecialistsltd thanks for the advice much appreciated

You knock it back till it follows the stone and looks tidy I should of done a close up After you do the knocking back put damp hessian over it

Hi this is hydraulic lime NHL 3.5

Yes lime releases water it wicks away Cement will lock moisture behind it

You can use Hessian inside it just keeps the wall damper for longer Mist over as often as you can Try and keep misting over for a minimum 3 days or as long as you can You want a slow set

Yes it will be lime probably black ash mortar or mixed with soot out of a chimney So you are going to repoint it then you want to lime wash it is that correct?

@@GMTpointingspecialistsltd it's quite soft and hasn't been done the neatest! Fortunately the render hasn't stuck very well to the stone so hasn't done too much damage. I've been looking at mineral paint as they seem to promise a good lifespan. I'd love to whitewash but unfortunately we don't have a very nice neighbour on the one side so access would be difficult to get every few years when it needs another coat!

@@shaunawilliams2739 mineral paints are good as there breathable Cleaning the stone depending how bad it is use a doff cleaning system or uses low pressure and steam Or acid are the only things you can use

I'd use a washed sharp sand choose the sand carefully make sure it's not sea dredged

​​@@GMTpointingspecialistsltd Will that come out like the colour your doing just now using washed Sharp sand.? Ive been pointing granite for years but using cement. Have you any tips for using lime in summer time. Someone wants me to point a house in lime that was built 100s of years ago in North East Scotland. It was all harled but was pointed originally and its patchy with cement and lime from over the years of patch work. Thanks in advance

@zeusricochant7357 I'd use a lafarge or Saint astier nhl2 or 3.5 Talk to the Scottish lime center they might know the area that you are working in If its to hot take the day off or rake out don't point I work under sheets so the wall is in a shadow Plenty of damp hessian and keep soaking the walls before and after you point

I dont do brick laying only repointing Try izzie the brickie he does bricklaying and was asking me about lime so might have done some by now

Covering with hessian In the summer stops direct sunlight drying it out to quick In the winter or cold weather Frost freezing rain and wind Clings to hessian rather than the pointing As long as the temperature is staying above freezing overnight its fine I'd still cover for 7 days to prevent frost damage Hope that helps

@@GMTpointingspecialistsltd amazing, thanks so much. Just googled your website, you're based in Buckley, not too far from where I grew up in Ruabon. I'm going to repoint my Mum's house there in the last week of March and am binge watching your videos in advance. I note you're fully booked up for most of 2024. Would you have say 30 mins for a video call for me to run some ideas past you and show you the sandstone itself and whether the existing mortar under the cement render is lime based? I'll pay you for your time of course

@hugh3sy7 yeah wattsapp me some pictures or videos And I can give you some advice and a rough area where the property is

Hi hot lime has its place I'm in north Wales the rain comes sideways So NHL 2 and 3.5 I use most of the time I switch to hot lime if it's a protected area And I can leave the Hessian on longer Compacting it back gives the lime it's strength not just it setting

Hi you need to speak to your conservation officer He will let you know what type of lime you need to use

@@GMTpointingspecialistsltd 👍

@@amyntas97jones29 also check the bag see what date it says on the side And use the lime that you have opened within a week and seal the bag up as tight as you can after opening if you don't use the full bag

Thank you means a lot as there's a lot of key board warriors trying to put me down for helping others Cracks appear for a few reasons Water drying out of the mix if you mixed it to wet The size of aggregate in the mix Did you mix it long enough Hard isn't always better as it needs room for movement Did you give the walls a good soaking before you started Did you compact it back with a piece of wood and chin brush How long ago did you do it I'm here to help send some pictures if you like I can talk you through how to repair it

@@GMTpointingspecialistsltd how long should you mix?

@bootangy I've done a couple of videos on it About 30 minutes I mix for 10 to 15 minutes dry mix Then when I add water 10 minutes minimum then after I stop mixing I let it sit for 10

@@GMTpointingspecialistsltd ty

Depends how long it's been on the bricks butWater and a rag give it a good rub Or failing that a light acid but if you get acid on your pointing it will change its colour

Black dye if it's a cement dye it's no good for lime Google lime supplies Ask them for grey brick dust or a grey colour pigment you can add to lime Wind will dry your lime out really quick so either wait till it's not windy or sheet your scaffolding up But be very careful as there been a few scaffolding jobs collapsing in this wind

@@GMTpointingspecialistsltd thanks mate. Will I still be able to rub it up the next day if it does dry a little faster than usual?

@@GMTpointingspecialistsltd I thought with the temperature being low that it will slow down the setting time?

@@ryandoyle1793 yes setting time will slow down in the cold but high winds will speed it up It could fail If it's a bit stiff or started to go white just missed it over with water and knock it back when it's ready

@@ryandoyle1793 just light mist it mate with a fine spray

You can build a wall out of anything really But if it was a choice of putty or nhl I'd choose nhl

Thank you, Glenn. As a boy I saw my father make putty for plaster. Some of the RU-vid videos are confusing hence my question. I work in construction in the states and everything here is Portland. Very few masons here understand lime mortar let alone use it.

@peterfcoyle9127 yeah a lot of miss information out there but the states have different temperatures to us But I try to make sure people understand that harder doesn't mean better You want to sacrifice the pointing rather than the brick or stone

Here it is all about production. Lime mortar sets too slowly. They want to be on the wall the next day running it up higher. Lime mortar goes up 6-8 lifts and you must wait for carbonation. I mentioned this to a brick ie once and he looked at me like I had two heads.

Hi I'm pretty sure I've done one If not I will soon

Your compacting the sharp grit and sort sand together it gives the mix it's strength

@@GMTpointingspecialistsltd cheers

Hi mist the first couple of days Then soak it after that it will have gone of enough but keep the hessian over it as well

@@GMTpointingspecialistsltd why soak it mate? I did mine last year first time was great, this year somone else's and cracking must be from sun getting on it can't think of anything else, But mine dried in 8 hours a day max and its not cracked odd, may be tho weak seem ok, ill have to do mine again if i get problems seems ok tho, nhl 3.5 like u and 3:1 I do It's 7pm got home hour ago and now gonna go back to they house and scrape it nooo lol

@mikede2331 what brand of nhl did you use Cracking can be You didn't mix it long enough It's too wet when you put it in the wall and it shrinks Soak it if its warm days to stop it shrinking as misting will dry in seconds

@@GMTpointingspecialistsltd it was secil 3.5 And sand was Aggregates for Mortar (Blaenavon) Mix 3:1 My house was also same lime same mix But sand they use in cardigan castle.. I need to look at that chart I think forgot what's it called now have heared some talk about it I'm south wales Swansea

You have to ring round to get the best deals I buy them in boxes of 10 £6.50 each they were last time

Probably 6 to 8 a year depending on the job

This is an NHL I'm using so it needs water to set Knocking it back with the churn brush gives it it's strength as it's compacting different shapes of sand together after care is protecting your work from drying out to quick Use Hessian and sheets and mist over with water

There's a few factors On how hard it is to take out and how many days it takes How much material your going to use What lime as some bags are £13.50 to £22 a bag What area you live in I'm north Wales so people from down south charge a lot more

I'm from the states I charge minimum for BRICK-POINTING by the square foot is $15 but for stone minimum is $18 minimum sound about right

@@jamiewatkinson4123 stone sounds cheap are you using sand and cement Or a NHL or hot lime

@@GMTpointingspecialistsltd $18 a square foot is cheap? I thought so what would I charge$25 a square foot?

@@jamiewatkinson4123 I'm in the UK so you need to find out what your competition is charging in your area Depending on there skill level compared to yours

The nhl is white It's the sand that dictates the finished colour I used a brown washed sharp sand

@@GMTpointingspecialistsltd thanks

If it kept damp depends on temp If it's hot do it within the first day If it's colder you can knock it back 2 to 3 days

@@GMTpointingspecialistsltd so this weather where I am it's about 19 at the moment keep it damp for a few days and just knock it once?

@@richardreese1974 What I do is when it goes thumb print hard is push it back with a stick first let it go off a bit more then hit it with a churn brush You don't want to over work it with the churn brush

@@GMTpointingspecialistsltd ok great! Yeah I've finished it off and gone over it with the churn brush once so keep it damp for 3-4 days

@@richardreese1974 give it a good soak after you take all your sheets off Sounds good what you have done

To put a shadow on the stone to keep it out of full sun

Lol I'm just a beginner at you tube videos It was the wind honest 🤣😅

?

If you actually watched the video 4 minutes in on the video you see me doing what you described I use the wood first to push any lime back into voids as just using a brush can still leave voids I'm compacting the 5 different sizes of sand together and giving that aged look If my videos aren't for you there's plenty of other videos for you to put down without watching them 😤

I'd have to do a site visit Or see some pictures first But I can't do it this year as I'm fully booked
