Great to see you back, i hope everything is good, thanks for your videos over the years, you and Kirk Johnson, have giving me soo much confidence to plaster and rendering, thank you 👍🏻

Thanks matey - I’ve taken a little break ha! Hope you’re well my friend and all the best to you and your family. Speak soon 👍

@@PlasteringForBeginners this is the opposite of future proofing. Ensuring in the future this rotting garbage will need removing. How do you sleep at night? How many elderly people have you sold this scam to?

[@bluevanmani]

Good work Blaine I did the Baumit course a few years back as well but we use a 1.5m toothed straight edge for the first coat and put the second pass on wetter and finish with spats. To be honest never really got on with the star contact like you said tends to tear up a bit, think ecorend FX4 is a much nicer product to work with but we’re all different 👍

[@ComeWhatThey]

Worth mentioning that there are limited scenarios where this insulation system is appropriate. On a ventilated cavity wall the benefit is undermined by the fact that you have outside air circulating behind the insulation layer. And on a solid wall you risk issues with interstitial damp, where they're designed to work with vapour open materials.

Would also be interested to know if the insulation boards are flammable - so much insulation these days is not fireproof

[@bluevanmani]

@@coolmonkey619very true. I don’t price for this system unless it’s a council grant. Don’t know if there’s any truth in it but was told what you save on your energy bill would take 40yrs to recuperate the cost of the work. So for me not worth quoting for just price for a straight out thin coat render

[@kevinhartle4494]

You may need to add ventiation to control moisture/humidity levels in the house after installing external wall insulation.

[@loneturk3y]

For the plugs you can get a eps router, perfectly cuts the recess. Tighten the mexhanical fixing so its snug into the eps inside this recess, then the plug finishes level and gap free.

[@TheMaintenenceGroup]

Been waiting for this video, thank god cz know am doing it to my house

[@ericmu4397]

You can use a special tool that will cut the insulation around each screw. So when you push the screw, the insulation is localy pressed down and then you can use more efficiently the insulation slice.

[@ontimecontractorsinc6513]

If moisture comes thru the outside or inside and gets trapped between insulation and OSB (assuming the USB sheeting is used) OSB would rut, probably need to use a thick vinyl mesh between insulation and OSB so the moisture could run down? Thx for the vid. USA is way behind on this, never seen it used in the US.

[@ontimecontractorsinc6513]

If it is to be used over USB, I would probably install Tyvek over USB and glued insulation only using PU or mortar and run the mortar vertically only on the insulation so the moisture could run down between Tyvek and insulation. Great, I answered my own question :)

[@Jonathan_Doe_]

Have you tried point a blowtorch at some to see what kind of smoke it kicks out?

[@mateo_dequ]

For those who have cavity walls I recommend filling the cavity first and then adding 75 or 100mm EWI. On top of that proper ventilation, ideally heat recovery system. Tricky areas are usually around roof eaves where often it's hard to insulate properly. In terms of durability of renders, for those who have some doubts i recommend going to Poland where over 90% of houses have EWI installed and you can check it for yourself. Most of my friends have it for 20-30 years and there is absolutely no issues at all.

[@Mobile-pd1uc]

Why if you need to put ladders on the top floor, do you need to be extra careful in the future? Does the render crack easily. Thanks

[@Gandalf4137]

I don't think that will be a problem. Good luck

[@weejim48]

Hi there , I’m a time served plasterer from way back and I’ve not done any rendering for over 30 years. I don’t know about modern materials but I am doing a job at home. I’ve removed all the vertical roof tiles from the front of the house ( trendy when the house was built in 1960 ) . I’ve put Eco therm insulation up and put cement board over the top of that, now I want to flat render it to match the rest of it. My problem is what material to use ? Like I said I haven’t done any rendering for over 30 years and I’m in my very very late 60’ . Any advice would be greatly appreciated. 👍

[@Gandalf4137]

A basecoat with mesh embeded in it and a top coat that appeals to you. 🙂 Silicone based top coats are nice, but they're not your only option. There's also mineral and acrylic top coats. Best of luck.

Blaine can the silicone render be applied to a masonry background after the base coat, or is it just insulation system and cement boards? Keep up the good work 👍

It most definitely can. Best of luck with your project.

Very informative video as usual - I'd be interested to know if such a system can be repaired. Ours is 10 years old and areas of the coloured render have cracked and come away to reveal the undercoat. Is it possible to apply a new layer of coloured render to patch?

[@DamnDealDone]

Well done. You just figured out the scam.

[@Gandalf4137]

Maintenance can be a bit of a problem with this system. Buying a 25kg bucket of silicone render for a small patch isn't cost effective. The answer is yes, but a patch is a patch. It's considerably cheaper than doing the whole wall all over again, though.

[@TejashPatel-z2r]

The only thing i regret about my ewi is then having to make repairs where I've had work done or moved things. Finding a way to renew the ewi is the biggest pain

Denser xps boards can be used below grade, if that's what you are asking. You can even apply a coat of tanking (hydroinsulating) membrane to the section that's going to be below grade. Hope this helps.

[@nsilva8334]

It makes no sense insulating the cold side of the wall . In building regs when you apply pir to cavity you fix it to inside block work leaving a 10mm gap between external wall and pir. Does this comply with current regs for something like an extension ?

I fail to see the real return on investment with external wall insulation on properties where there’s a cavity. If you have the space internally it’s far more efficient to insulate the inside of external walls.

It’s overkill. Just drill a few holes and fill the void behind the brick with expanding insulation foam. Cheaper and quicker

I'm in the process of doing mine and about to apply the base coat render, but will spray the silicone. Installing the insulation boards is relatively easy, but it takes a lot of time on your own. If I struggle with the applying the render I will hire a pro for that part. Doing the install yourself is about a quarter of the cost of hiring someone.
