Accelerators for K-REND FT

[owls]

Not sure how the batch mixer mixes it as I never used that type of machine. @owls will tell I he had one.

Krend ft certainly does work better if it is mixed twice as stated on the bag but egrade and k1 will be different to ft and ft won't be going any where near a pump asbit won't mix or convey

Yep I used it with batch mixers in the past a v2 and sp11,
We had nothing but problems with it, hence we've never used it since.
For me it's the quality of sand they use quarried from Larne it's not very good.
The rep has given me a pallet of k1 for nothing to get me back on with it, but it's still in my unit, that tells its own story. It's a shame because there base render such as hp12 etc are a good product but there top coats are dross.
Our problem was shade variations in the batches aswell this was 2009 so they may have rectified it by now, but why take the chance with good renders such as monorex, enewall, pral m etc about.

Spoke to him yesterday and basically he said it can be a one coat application but pretty much all substrates bar dense block have to have a pre base ie hpx- hp12/14 which basically makes it two coat but suppose same with webber/rendaid and parex

I thought it was a 2 coat after speaking with Steve in Ireland. Treat as sand and cement he advised but buoldbase wanted alot more than sand and cement prices.

Weber OCR Parex parmurex etc can be applied straight to the substrate in one coat finished coated with acrylic or paint will be warranted.

That's one of the specs I've been given
One coat of gpmortar

 

[Kylewesley]

We always pre base every thing unless dense block, it gets charged and top quality job.

So how would they guarantee shrinkage from suction on hack off or celcon?

Or on old face brick that it won't blow?

I know what your saying about s&c prices compared to any bagged system but most of our work revolves around hacking off failed render or new build on celcon or render face brick.
My days of hand balling a 40m flank with s&c are a thing of the past when you can do the same pumping on in half the time and get another 40m on on top of that

Aye I just can't see how it can compete with one coat renders if it needs a hpx or a hp12 first. Time and cost are beyond Weber OCR.

Shame cos I hear its nice to work with

But surely if your rend-aid and meshing it the same?

Or are you just applying OCR straight up?

If the background needs rendaid yeah it is but if its straight masonry block then direct onto with one coat

Load of bollox really isn't it?

What was the spec before they made gp mortar lol [emoji12][emoji106]

They'll spec whatever is needed to sell more gear

If agree with that but ultimately it's more for us.
Charge accordingly and clean up.
We don't compete with the traditional and used to hand ball tonnes of it on 10 years ago

I've stuck to using UF base it can be done in one coat and is really nice. The mortar is just a cheaper product but buildbase are cashing in on the mark up I think. I pay 5.25 for OCR the kmix would need to be 3 to 4 would it not? Buildbase want about 6.90

That is a rare occurrence that the building has been constructed witha dense block

 

[BigK]

So did I, all handball, used less of it in recent years in Ireland.
A lot of people actually use k rend as a sand/cement replacement for top coating for a knap finish.
It looks good, and goes twice as far as its on lots thinner.
Just to save them painting.

If you were to go by specs on self builds it would never get used at all over here on houses

Do they spec that on celcon?

Sig do it cheap all the systems work out about the same give or take but sometimes worth paying bit more, sometimes not

Fair enough
We try and stick to the high end guarantee everything just peace of mind I guess.

7n block most commercial buildings we do.

House builders using 3.6 or 4 it seems I was only saying that on here about wrong block getting used on houses

7n blocks are minimum to render straight into but IMO unless they were dense concretes we would still want to base/ fully mesh the lot.
Or get rep to spec it but just stops suction and shrinkage
I suppose just the way we work.

You shouldn't ever get shrinkage on 7n with Parex or Weber. We use a warranted spec direct to that block for years. Less than 7n and you need microgobetis or rendaid.

All blockwork meshed regardless of strength

 

[BigK]

What's this 7n business fellas?
Educate me!

 

[Kylewesley]

It's the compressive strength of a block under 7 and spec will be a base product.

Still get 7n that look like lightweight but as said we base and mesh pretty much all jobs.
Kills suction too.
I know they spec that it can go on with certified guarantee for product but we always go full works unless conkers

 

[BigK]

What would 4 inch solids be then?

 

[User___removed]

No builders round my way give a f**k about guaranties or mesh in first pass.
Most want cheap sand & cement then painted.

We stay away from these jobs mostly as we work on reputation and sell our work with the guaranteed spec .

Can be either mate.
Usually u can tell with the weight of them.

There low suction so u get plenty of time where as 3.6n suck in like B####

7n takes a pass with your mesh then a top out and sits nice, sometimes on lower strength you can be chasing it.
You don't see many cracks in 7s or above where as with 3.6s there is a crack in every building before u render see pic

 

[BigK]

What is it measured in? 3.6 what? 7n ? What's the n stand for?

 

[owls]

newton strength

the problem is now aswell is the compostion of 3.6n blocks bits of recycled glass coal allorts of rubbish.
