Waterproofers a retarder Danny you're talking shite if anything you want render to breathe as much as poss if we didn't 2 coat we'd use lime to allow the building to breathe
What do you think we've got cavities for and stone Walls where you haven't got a choice and then we have this magic product obviously freed hasn't looked up yet which is masonry paint which waterproofs the outside of you're building mental innit
Traditionally in the uk we 2 coat render w/p is used to re***d the mix because if you're getting a 40m gable on on you're tod in the middle of summer you'd struggle
And we use lime to soften the mix plastercise it and reduce cracking
I've never used and never seen anyone use waterproofer in the top coat in my life
If it was that good why aren't damp proof companies using it instead of injecting it or using bitumen......it's a retaaaaaaarder it does fook all else
 
Why all the worry about frost on the surface & water soaking into the render??
Don't people have painted render anymore then LOL.
A good quality masonry paint let's moisture out but not in!!



Edit:
Oops... didn't see your post about paint Spunky before I posted. :RpS_biggrin:

Why is it bullshit?
Youve not got a clue youve been on a short course and now your turning into a bigtime subby lol Oasis springs to mind again another bloke who wouldnt listen to good advise, only what he wanted to hear. So come on smart arse explain why its bullshit and dont just say "it is".

It wasn't a short course and I spent 2 years with spreads after I finished college. Just because i didn't do an apprenticeship doesn't make me any less a spread technically or knowledgeably than you. And yes I do sub alot of work out, got a problem with that? I tell u now if some1 like you came along to me with an attitude like yours and a big chip on their shoulder asking for work i'd tell them to f**k off.

Yeah, I've used the everbuild 3 in 1, not bad but I don't rate it as good as Freeflo for giving you plenty of time on pebbledashing especially. Do you make a lime putty the day before or just add powder to your mix?

I totally agree on the Freeflo and used this before changing to the 3 in 1. I prefer the 3 in 1 for the exact reason in allows more water back in. I usually keep wetting my first coat down for the first two or three days after application to make sure it cures nicely and often found that the Freeflo just wouldn't allow enough water back in even a lower doses.

That's a blast from the past Bubbles, I remember years ago in Ireland mixing the sand and lime days before to let it 'sour'

Lime putty makes for a superb mix - we were always told that it 'de-activated' the lime by mixing it into a putty and standing for at least 24 hours. It was always a laugh trying to mix a big water-butt full of it with a plodger, everyone taking turns to have a go :RpS_laugh:

If you want render to breathe you shouldn't be using sand and cement in the first place. Paint is for further protection and decoration.
 
Sorry Bubbles I forgot to say I just put the lime powder straight into the mixer, always first thing into the water.
 
Do you cover the mixer Andy? I learned a wee tip just the other week (never too old) the lab was throwing lime into the mixer (belle size) and then placed an old dustbin lid over it. Perfect fit and everyone could breathe :RpS_thumbup:

I think you're the one that doesn't have a clue. :RpS_lol::RpS_lol: Why do you want it to breathe?

It isn't JUST a retarder it also weatherproofs to an extent.......ok scratchcoat 2 walls. One with a pint of "3 in 1" in per mix and another with none in. Top them with the same mix and tell me again that it's just a retarder. :RpS_lol:

I've done s**t loads of rendering dave with a load of different plasterers and got trained by a few teams of old schoolers.....they all used waterproofer in the topcoat. Just because you haven't seen it doesn't mean that it's doesn't happen.
 
Of course you want the render to breathe as much as possible you're the one going on about water ingress and it blowing the top coat which is b*ll***s :RpS_lol: water will still penetrate a waterproof topcoat left unpainted it will penetrate a 5-1 with lime and a 4-1 with waterproofer
You don't have to use sand cement with any waterproofer you could use it just with lime if you didn't want a brittle mix it will still offer good enough resistance to weathering

I've never covered one for that reason but have covered it with a piece of tarpaulin tied on so as not to splash everywhere when cleaning out on a tight job. I've got a little Belle mixer for home use and I'll remember the lid trick for next time.

Thankyou Danny, my point exactly.

BTW never said leaving waterproofer out of the top coat is wrong, but its just common sense that if you leave it out the building will retain more moisture, and be less resistant to the weather. This in turn will have an overall effect on the building as wet render is a poor insulator, and can cause problems internally with condensation.

Putting waterproofer in the top coat won't cause the problems like Flynny is describing it is perfectly safe to do so.
I don't know where Flynny has got this complete nonsense about problems when putting waterproofer in the top coat have you personal experience that can be put down to this Flynny that you would like to share? or is it just something you have read/made up?

Also please explain Flynny why on some jobs you would put waterproofer in your top coat, e.g ''seafront, 3 coat ashlar work'' why are these the exception to the rule? whats going to stop these falling prone to the same top coat blown phenomenon?

Look Mr knoiw it all here is a thread you started in Jan "Ok so whats the score I've never rendered this time or year"
"Does the bellcast have to follow the damp proof course? or can you leave a gap to it roughly 10mm."
Heres another classic from november "If using wet sand do you just dilute the waterproofer less." and "If the mix isn't wet enough is it ok to whack some clean water in?
And this shows how much of a prick you are "On a building with a cavity where the cavity is the barrier to water a more breathable render with lime no waterproofer would be best as it can naturally dry out between exposures."
Stop talkin like acunt im nearly convinced your oasis but with the missus typing, im not gonna waste any of my knowledge on a little jumped up prick like you so **** off xxxxxx

Grow up Flynny. xx

That post you refer to was from 2008 Flynny and you gave me the wrong advice. There are certain circumstances where I would leave waterproofer out as I said and this is why we were taught this way in college. Thought you would like the above lol

I gave you the same advise, i cant read that post above the picture is too small. Youve not answered why you would leave it out or put it in, your trying to find out arent you? I read your prevous posts coz im sure up until last week you wasnt an expert on rendering i think the "How do i skim a bullnose angle without a special trowel" thread gave it away. Dont bite the hand that feeds you that was oasis's mistake, aint that right xxxxxxx
 
Lol you just don't stop do you Flynny. Do you want me to blow that picture up above or shall we keep it hard to read? Considering you just took the piss out of me for a post I made that you actually clearly put you 'agree' with maybe we should leave it small.

As for the bullnoses heres the finished job xx

Blow it up i cant read it and that skimmin looks ruff as **** and will never dry :)
 
LOL just read it and i was agreeing with the last bit, which ive been goin on to you about, but in four years youve found a better way or lets call it a fools proof way just waterproof the lot, so good luck. xxxx
 
Flynny you really are pathetic and have shown your true colours in this post. I spoke to the decorator yesterday and he said the work was excellent, no prep required, in fact Flynny he and all my customers say exactly the same lol. The quality is poor so that you don't try and nab it and pass it off as your work.

£800 for that job xx

Lets see some of your work on the forum Flynny? need a laugh.

Put us side by side and I reckon I'd f**king rinse you on speed and quality.

LOL i was jokin about the ruff bit, put us side by side but you better hope theres no bullnose angles coz you will need a special trowel xxx
 
we only use waterproof additive for dashing, in the scratchcoat.
you must increase the cement content with waterproof as it will make the mix weak.
we use lime in top coat, we also think that lime quickens setting time
 
everyone has dfferent methods of doing thngs, but as long as you all get the same result, its here nor there.
