I'm trying to Narrow down the best modern render for me, and Method, I've just brought the detached bungalow all the render needs hacking off I was going to base coat and mesh it and give it a scratch finish I'm primarily a plasterer not used much modern render other than a bit of K Rend, which I have heard is cracking a lot on old brickwork, I've heard a lot of good things about johnston's render, any advice on the best product to put straight onto old brickwork and the best bonding agent/seal, to put on the brick work prior to rendering would be much appreciated
 
i would either use rend aid or sbr. if i was going on to brickwork.
if you are going to replace the whole bungalow i would consider an external wall insulation.
 
I now there's the added benefits of insulating the bungalow but it doesn't need it and it's extra cost

i am sure it is law now that when you have a complete render it has to be ewi.
i have had the local council after my customers over this.
 
That's b*ll***s its up to the customer what they have .

Nothing wrong with k rend. I use it all the time . You'd need a R7 prime then a base coat either hpx or hp12 with mesh bedded and then k rend top coat . I never had it crack once ?

talking about b*ll***s, are we talking about your or a clean pair?

there are new rules about external insulation. we are carrying out ewi on properties that are to be rented out to the dhs. they will only pay the top rent if the property is properly insulated.
some of our customers have received a visit from the local council , on a main road, after we had removed the render from a private property, telling them that a ewi system was required.

You didn't state that earlier Einstein.
 
K rend was my first choice but a few people have put me of it, but I suppose there's more k rend jobs than any so if you see s**t modern render job it stands more of a chance it will be a k rend job because there's that many of them been done over the years, properly s**t application not render, there's definitely no law saying you have got to have ewi, housing association's and council's probably have to meet standards with it but not private.

If you are re-rendering more than 25% of a property building control need to be notified and the u-value needs to be up to current regs.
 
It's a very grey area,
Local building can't inforce it only as a guide, as well as if you can argue it would be undue cost to fix 90mm of eps (current building regs of around 0.3) that you'd have to alter roof lines or extend cills etc. I wouldn't inform any building control unless the buildings grade 2 listed or in a conservation area.

I explained the situation to one customer and they decided to fly under the radar so to speak and just re-render. They had a letter from building control and had to insulate a couple of rooms inside instead.

I'm happy to do as the customer asks,just as long as they know what is what but some of these BC officers are like coppers and are always on the job!

The mesh should be in the topcoat of krend
 
This insulated render as a must with the council is a complete surprise to me I'm primarily a plasterer but I do about 3-4 sand and cement rendering jobs a year complete houses, probably for the last 15 years to, and a lot off them for builders with building control in and out the jobs as I'm rendering nothing's ever been mentioned, like I said it's a complete surprise, surely this must only be for authority houses.

Yeah you are and i ain't your f**k**g pal
 
I mention the building regs stuff briefly so if the customer gets caught I don't get the blame.

Regarding meshing the top coat, the manufacturers prefer it in the top coat but I disagree.

I fully reinforce the coat stuck to the substrate and put decent size stress patches in the top coat.
