Help with kitchen renovation/ 1st house.

[zoothorn]

Ah that's odd: my Jewson confirmed order code saying tho only 2x edges tapered.. short sides > but asked her to check & no its the 2x LOOONG sides tapered. Great. I guess thats -better- then than 4TE, not having the taper at ceiling?!

 

onoff do you have a rule of thumb no. of screws for an 8'x4' PB..? maybe I can use as a guide as to how many zillions I'm gonna need.

 

And what distance between the reveal sections' screws a good figure-?  sorry if Ive asked these Q's before.. just I'm onto this tmrw.

 

What I do have is one 5mm deep plaster area 'blown' (I had to resort to a steamer to get the godawful disaster-paint off other walls hence dmg) adjacent wall to the PB to put on. do I need to address this before the PB get whacked up next to it?

[Onoff]

If you go 150mm centres then about 68 per full board sitting over 4 vertical studs at 400mm centres. At 200mm centres then 52 screws.

 

Squirt some low expansion foam in the gap behind the batten and cut flush with the batten when dry. You can patch plaster the missing area later on. Shouldn't affect what you're doing now.

[zoothorn]

Good plan.. will do. glad I don't have to address this before, it looks a pig of a job/ never done plastering.

 

Ive got similar blown areas on the 2 'other' walls. All day stripping one, about 30 holes in, alot of my smaller graft/ scrape marks all over, plus blown areas to fill.. a horrible day. As bad as walls get/ in a terrible state, badly built > then plied with awful diy jobs + 20 yrs of paint layers caked on to strip inch by inch. urgh..

 

 

[zoothorn]

How long to wait after applying soudal LoExp foam for it to cure/ to cut flush? And how much does this stuff expand by? no info on can in either case..

 

if I'm using it as an adhesive to stick the insulated PIR down to the mortar, plaster in reveal area.. won't it push the PIR sections up/ or out (sides) when it cures/ expands-?

 

Wednesday didn't happen for me.. no idea where it went.. so Im a day behind/ the PB boards delivery today PM. How do they get delivered by the way.. upright or flat? if flat, is it possible to lift one of these 8'x4' up alone, or will this split it? maybe I can ask deliver guy to help me into hse with them/ store upright (longways).. not sure if that's wrong to ask.

Right .. read carefully and follow to the letter ..!!!!

 

Trim your PIR to a reasonably tight fit. 

 

Lay it flat on the floor and put two lines down the board about 75mm from each side. Aim for the lines to be about 30-40mm wide. 

 

Give the foam a quick spray of water and then leave it alone for 5-6 mins. 

 

Foam will expand but stay tacky enough that when you lift it up and push it in it will stick but not push the board back out. Just hold it in place for a minute and job done. 

[Onoff]

You're going to have to experiment! 

 

The deeper you fill with foam i.e. the more volume in the hole, the longer it takes to set. Temperature etc plays a part too. 

 

Squirt a couple of lines on a bit of scrap. First it's as sticky as. Then it forms a skin but is still squishy if you push it with your finger. When set its quite hard. You can give a flick with your finger and it'll sound like a sharp knock. Try cutting your test bit with a saw/kitchen knife. If the blade comes out sticky it's not set!

 

Just do some say 5mm beads on the mortar of the sill spaced a couple of inches apart. Lay the sill atop and weight with a couple of bricks. It's LOW expansion, the weight of the sill and bricks should be heavier that the foam can push up.

 

Pb usually gets delivered flat, maybe on a pallet. If moving yourself then transport it "landscape" with the carrier you bought. Lift the sheet upright from the long side. Have the carrier ready and lift one end up and drop the board in the carrier about mid point along the boards long edge.

He's going to moan now about who's suggestion to follow...

Soudal Low Expansion foam...all about it:

[zoothorn]

No way he's not! I'll do ~midway between suggestions.. appreciate the replies/ good timing the boards are here in an hr.

 

is getting them into place from landscape to portait able to be done alone do yoy think? or is that a defo-disaster idea..

Ah yes thanks, this info is on the can too.. but oddly zilch on the 2 basics I need to know.. how long to set/ how much it expands to.

How long is a piece of string ..?? Basically this stuff is temperature and moisture dependent - warm and humid it expands more and sets quicker. Cold and dry, it’s lower and slower. Manufacturer gives the expansion I think at 19c and “average” humidity. They don’t know if you are using this on an unheated building site in winter or in a warm bathroom ....

Ok understood, I guess its sort of mid/ average temp now: I'm just trying to guage what 'low' may be relative to std 30x, 60x cans.. no probs as I'm yet to get screws. I'll try email the Co..

 

[PeterW]

Just follow my instructions and it will be fine

[zoothorn]

Ok Peter thanks. I need all help as feeling like cr*p! (I did read but overlooked onoff's link/ which is different ["low to minimal expansion ~50%"] sorry I thought just the same can spiel again.. odd not on it IMO.

 

Once I get reveal 4 bits in place I'll have some mojo back I think.. this ev I hope. godawful walls/ terrible strip job & prep to do, & general pickle in here is getting me down a bit tbh. I need to see progress for a pickmeup.

All good things come to those who wait! ?

 

Can you set up a webcam for when you next use the foam? 

 

 

[Onoff]

Have a practice like I said with the foam on a bit of waste board. It is not as aggressive as the other stuff but doesn't mean you can go nuts with it! It doesn't need much against it that it won't push the board out but rather fill the gap.

 

This is one where you're going to have to do it to get a feel for it. Short of someone standing at your shoulder it's the only way. 

[zoothorn]

Got my TE 6x PB's all stacked next door room.. that's progress. omg sooo big & scary tho.

 

no more pics of my foam beings no.

 

 

[Onoff]

Take it EASY. If stuck don't panic just post up. Nothing worse that effing up good materials!

[Onoff]

So you got them in, in landscape mode using the tool I said to buy?

 

All intact?

[zoothorn]

Got them in hse longways, helped by friendly Jewson guy.. so great I can rtn that whatnot.. until he promptly ripped it open to show me how! damn there goes a tenner..

 

Ok now I got a silly no. of 50mm screws (they only had 60mm): I need 50x but smallest box 500x. Then a box of 1000x 32mm (need 450 max). Then a whopping great roll of (paper) jointing tape.. from here to the moon looks like, & a whopping great 25kg bag of compound to mix.

 

Is that all OTT flippin daft?? still no extension boxes in town.. another week.

 

 

 

 

 

[newhome]

Plenty of supplies for when you come to do the rest of the rooms then ?

 

 

[zoothorn]

Yes.. blimey this job might put pay to my considering that whopper job, but let's see how it goes.

 

Just had the C'tex (both sides foiled/ good) & the 1x ins PB.. but its tapered edge.. the tapers along the long edge too. Is that the wrong stuff?

Is Welsh your first language?

[zoothorn]

I've cut the 4 insulated sill panels ~ok.. going over your pg6 stuff again/ just noticed the cupboards Q: may have to put a noggin or 2 in before the reveal sections. You see how things you've kindly said ping out -only- once I'm actually on the job in Q.. that's just a total newbie.

 

The Ins PB isn't great quality- 2 sections separating at one edge, so I hope whatever is gluing the PB to the polystyrene won't fail over time/ not giving me huge reasurrance tbh. Anyway whether or not tapered was meant to be (for the 1x insulated reveal PB) its cut now.. so has dips @ sill sides, top sides & side panels twds top/ hope they won't look shoddy. The polyS didn't cut well at all/ rough edges even using much as much precision as I could with a new knife blade.

[Onoff]

Pictures help massively in trying to understand this.
