Great videos mate, love it, building my own house here in donegal, plasterd my shed last year from watching your videos, having a crack at the house this year.

You decorated that wall with cement to perfection despite those scorching temperatures. Definitely worthy of an ice cream after that job :)

Have a nice time my

HI Mac, you always make a job look so easy, great work, liked, have a great new week :)ms

[krzysztofjastrzebski]

Hi Mac, hope you're well. If possible would you mind to advise please:
1. Is scud coat required for this fence wall?
2. For scratch coat is better sharp sand?
3. Is better to add lime for a scratch coat or no need ?
4. How much sbr should I add to mixture?

Thanks a million for that

[duckman]

Thankyou Mac, great helpful vid, cheers

[paulgorman]

Would you ever scud a wall like this first, or when would you scud a block wall? tks

[mingyang]

I wonder if the other side of the wall needs damp-proof process before you do rendering on another side?

[HSilver]

Can’t beat that time of year outside cracking on with that 👍

[AyiviTV]

Very nice👍🏼 Please, for concrete wall plastering, how many square meters of surface area will a 50kg bag of cement cover on average (outside and inside)?

[henn]

Lovely job 👍
What ratio sand/ cement do you use for scratch coat and finish coat?

[TheNomadicTrader]

Making that gear look lightweight! Top job

[bootsmclaughlin]

Yes lad long time no see...hi did you put any waterproofing in the mix on the scratch coat what's the ground being hired behind The Wall would it make any difference to put something cheers big lad

[dariaszymanska]

Great job thanks for sharing Mac ! Did you use SBr prior to applying render ? And did you use mesh on your scratch coat ?
I've built similar garden wall /flower bed recently (all constructed of breeze blocks) and was wondering if sbr / mesh is any good on new build walls? Also did u add any placticiser to your sand /cement mix?

I’m 3 weeks into plastering course at college nice vid mate

[Billy-Handler]

What about the damp course? Or doesn't it matter with it being a wall. Thanks

[eire]

Good quality video Mac, what ratio was ur scratch coat

[jameselliott]

Do you have any information on ratios for airtec blocks I can't find anything anywhere. I am panicking that they will blow with a to strong a mix

[kevfitzy]

Great Job, what kind of mix did you use? and would the same mix work on an interior wall?

[battonfive]

Great job :-) I like how you consider the diffrent moisture levels for top and bottom with ground water and sun exposure, I can see that making a really big diffrence in long term strength of bonding to to the block i must admit :-D Thanks for the share, I can really see your technique here, like it would be hard to replicate to your extent as you make it look so easy but it gives a great idea for folk like myself who are still early learners of the trade :-) My best my friend.
