HOW I PATCH DRY DASH RENDER,ROUGHCAST,PEBBLE DASH DEMO PART 1

dry dash is a very hard plastering / rendering job to undertake both physically and mentally demanding on large and small jobs. Plastering and rendering is physically demanding in the fact that you have to use your body to get the job done and sometimes you gotta work hard and fast to complete the job to a high standard. plastering and rendering is also more than meets the eye as you have to know a lot of info for certain jobs as in when a big key to plastering and rendering is timing when to do what and why also knowledge of the suction the wall might have in certain areas and why and what to do about that what chemicals to use when and why and where such as bonding agents in the mix or painted on the wall and also water replants there is a lot of let's say sciences and maths in plastering and rendering. This is why I say there is more than meets the eye but I plan on helping all my viewers out trying to make the videos enjoyable and keep them as short and sweet as possible while at the same time make them knowledgeable and put as much info into them as possible, so I hope you enjoy and learn something from the demo on HOW TO PATCH PEBBLE DASH RENDER , DRY DASH , ROUGHCAST

Roughcast or pebble-dash is a coarse plaster surface used on outside walls that consists of lime and sometimes cement mixed with sand, small gravel, and often pebbles or shells. The materials are mixed into a slurry and are then thrown at the working surface with a trowel or scoop. The idea is to maintain an even spread, free from lumps, ridges or runs and without missing any background. Rough-casting incorporates the stones in the mix whereas pebble dashing adds them on top. According to the Encyclopedia Britannica Eleventh Edition, roughcast used to be a widespread exterior coating given to the walls of common dwellings and outbuildings, but it is now frequently employed for decorative effect on country houses, especially those built using timber framing. Variety can be obtained on the surface of the wall by small pebbles of different colours, and in the Tudor period fragments of glass were sometimes embedded

Does the waterproofer make the mix stickier? I tried today with a mix of 1 part white cement and 3 parts sand and a few drops of washing up liquid as plasticizer but the plaster wasn't sticky enough for the smooth, rounded, 1/2 inch size river pebbles to adhere properly to.

Any tips for getting the plaster sticky without any additives except for cement and sand?

I noticed that the stones stick well to a paste made from just cement + water (zero sand), so could I use that?

I always wondered how this was done. Thanks Mac :)

Hello Mac thanks for showing us how this is done I have a project down here in Victoria Australia on an 100 year old house it has weatherboards running at around 900mm in height then a solid looking timber sill then the dash mix above that to eave height around 3mts I am quoting that requires a similar type finnish. My question to you is the existing stone seems to be around a 20mm-40mm stone I plan to hard board the existing stud wall ( cement sheet based product designed for flat rendering) fix chicken wire as a reinforcing then build out with a mortar mix sand, cement, waterproofer mix . The stones being the size they are would you still flick them on like you have .
Cheers mate love your work Trevor

Great video! Plastering is a real skill 👍🏻

Fair play to you doing pebble dash on your todd Mac. I used to hate it. Probably psychologically damaged at a young age, as my first solo job was an office courtyard (Old Brick) it had loads of suction and it was a baking hot day.
Thought I had it all sussed out until I went back to throw the dash on most bounced off again Had to put a load in by hand :-) :-)

The worst thing was all the office staff were 'down-tools' and watching me :-(

Thanks great video you make it look so easy

Nice job Malc. Been using my ox dasher the last couple of years, had the 6inch Refina one before that, expensive but lovely to use, lost it somewhere 😂.

That heat was a killer Mac . I had smooth cement render wall shrink 2 quick and crack and was hydrating it for a few days after . Do u put waterproofer in both coats and how much ml u use in each . Some guys I know use about 500-600 ml in a scratch for a barrow full . Others about 100ml.we generally use Free Flow.

Super Klasse DEMO Video !!! Great work :)

Hi, my pebble dash looked great yesterday when applied but today there are some dark patches. Do you know why? Please help stressing out 😂🙈

[scottmclean]

I can't find the grey pebble dash in wickes, b and q or Travis perkins.
Can I use 10mm pea gravel or will it be too heavy and fall off?
I'm painting it anyway so the colour doesn't matter

[pictlandpickers]

What mix are you using and would you pva a scratch coat that has been up for a while

[nom]

what is the white plaster your putting over the sand and cement scratch coat?

[irishguy]

Is that sand and cement that is plastered on for the stones. How come it looks so white, Is there lime on it

[Ali-kgsh]

Good luck with the videos and channel 😀👍

[MrPaulie]

Alright mate,
It's been a while.
Quick question with render I am going to do a project inside with render. What do you reckon I could use to put render on plaster board to prevent it from soaking moisture through it!

[michaelcollins]

what is the best way to get my house roughcast to be pure white? would that have to be white sand and white cement scratch and top coat?

[irishguy]

How does the pebble stick so easy to it.

[scottmclean]

This is great as it's exactly what I need to do on a small area of my wall.
Is that jus a normal sand and concrete mix, looks very white. Can I message you on Facebook messenger for a couple questions if you have time. I know how busy self employed guys are so no probs.

[scottmclean]

Can I use the product U CAN REPAIR RENDER from B and Q for the coat to the wall then dash it?
