zoothorn Posted July 30, 2018 Author Share Posted July 30, 2018 Cheers Ferdinand.. useful having some encouragement. I took the plunge today & ripped off bits Peter noted (BFO red marker) & altho I scratched the frame to chisel superglued bits off, & altho the window -does- seem to be fixed in by foam alone (alarming!).. job done. Frame seems solid & no gaps to fill in fact top or sides, just the sill. So I'm ready to tart the sill up. I'm ok foam-filling the gap, but how to make a new level area in front of it? is it a Q of mixing some mortar stuff up making a wood surround to put the mix in front of or s'thing? a 5min job for the experienced.. but a head-scratcher for me. thx zoot Link to comment Share on other sites More sharing options...

(S'fix do a No Nonsense uPVC cream cleaner which is good). Foam the cavity. Let it go off. Cut it level. I use a cheapo, bendy old bread knife but a hacksaw blade will do. If the blade is coming out sticky as you're cutting then it;s NOT gone off. If you cut foam too early you get left with hollows. Tbh you could do your pb up to the underside of your new / extended sill and bed the sill down on some dot n dab low expansion foam making sure you do along the back, sides and front with a thin line too to seal the edges. Another option is chuck some mortar in there and level off then tile above the worktop and tile the sill too. Link to comment Share on other sites More sharing options...
zoothorn Posted July 30, 2018 Author Share Posted July 30, 2018 Ive foamed the cavity, stuffed eps in there before. so waiting for it to go off.. then I'll cut flat (@ the 3 'resting' white things line/ the 3 do-da's the frame seems to be resting on- I left them as is in case doing s'thing re. support).

What to do for the majority on which the sill sits, in front of the foam rear strip? and am I using 27mm PIR insulated stuff for the sill itself?

It takes some time to go off in the middle. I have a video of the process. If it is threatening to hit any surfaces you could put tape or a thin board there before it arrives (are any of those trims scrap?) to avoid any of the sticky being on the surface .. tough to get off afterwards. If it does go too badly into corners etc you can usually cut it flush using eg a hacksaw or reciprocating saw blade or craft knife or eg bread knife that is ready to be thrown. I had a foam that lost its top by accident once. You do not forget when that happens. But it will be OK afterwards. You need to worry more when it has nowhere to go and forces your wall facing out wards. Edited July 30, 2018 by Ferdinand Link to comment Share on other sites More sharing options...

Onoff Posted July 30, 2018 Share Posted July 30, 2018 (edited) You really never have used this stuff before have you? At least it'll be well filled! Norm is to 50% fill with the regular expanding foam. That amount will take a while to set. Says on the can only fill 50-70% of the void you're filling. It'll be dry tomorrow. Did you try and fill the WHOLE cavity with it or just the top few inches like I showed with the eps? Use the foam gun cleaner as an aerosol to clean off the wet foam from anything you don't want it on. You did get the gun cleaner I said was a must?

I read that whilst in a meeting. Made me laugh and everyone stared at me lol. I was going to use that foam once. My brother told me ‘don’t use too much and don’t panic if it starts expanding like mad, let it settle or you’ll make a mess of it’. I decided to let someone else loose on it ?. I imagine next time you will use it more sparingly? ? Link to comment Share on other sites More sharing options...

I get in a pickle with it every time. if you look at the Co's video clip to promote it- I'm not on it. Not the whole cavity- I stuffed a good polystyrene 'rail' in 1st so just a 4" x 3" area to fill.. then I just went beserk with the foam can. I think its these pills. I've just cut most of it off, & hit it with a hammer to make sure its quite dead.. but I'm left with an uneven sill 'bed' to put the PB ins stuff onto.

zoothorn Posted July 30, 2018 Author Share Posted July 30, 2018 (edited) No I didnt use the foam gun- cos the can I had way before to use with it was the other type, drinking straw etc. I might use it for the blue low expandi stuff (not got yet).. unless there's something else I can attatch the PB ins stuff on with instead.. thereby returnng it/ £25 refund as screwfix are good like this: I bought it for this foam can tbh/ got mixed up with your info. Could I use the no-nonsense grab adhesive to stick the PB ins stuff on the reveal 4 sides instead? would save me ~£35 or so if I could. Didnt get the gun cleaner/ poss not needed(?). Another day of little done sheesh- 2 battens on other wall (1 a total bitch that took off a lot of the other inside window reveal side wall I now have to fill/ had to re-attatch it 4x) & the sill filled/ impromtu zoothorn foam party. I plan to do this wall 1st before starting 2nd, as that wall has sink/ needed till last minute as it'll take me a good day or two to fit the new one & its unit onto the wall. (I did compression joints once last year.. but can't remember how the heck I did them). Edited July 30, 2018 by zoothorn Link to comment Share on other sites More sharing options...

zoothorn Posted July 30, 2018 Author Share Posted July 30, 2018 No- I can't cope with mine let alone follow another! I need a productive day tmrw. Can someone advise how I do my sill 'bed' once Ive tidied up the foam? it'll need something to fill & make a flat area, in front of the foam 2" twds back, on which it'll sit. Ive seen onoff's info, but its so neat.. & I can't tell exactly how he's done it.. esp to get flat & level as will be pretty important I guess. Then I can crack on with the C'tex/ that should be a productive & satisfying job > then onto the dreaded PB job. Link to comment Share on other sites More sharing options...

Just cut that foam monstrosity level and stick your insulated pb direct to that. I stuck my insulated pb on with a combo of Sikaflex EBT and some low expansion foam as said above. Tbh the screws attaching it to the batten are doing most of the work. Screw yours around the edge like I did and on the back of the pb put some big blobs (don't skimp on it) of the No Nonsense grab adhesive under the sill, behind the side bits and the bit at the top of the reveal. It's cheap enough. Put some bracing timbers between whilst it sets to keep all square. If using LOW EXPANSION foam then weight down the insulated pb with bricks. You will need long dry wall screws ideally. I think ordinary ones might rust and show through? Remember the side bits support the top and keep the ends of the sill bit down. Yes I'm neat...but if I look back at what I did way back on my first house I probably wasn't. New things are scary until you try 'em! I'm putting off tanking my bathroom because I've never done it. Does mean that today I've sorted a few niggly bits instead though! Edited July 30, 2018 by Onoff Link to comment Share on other sites More sharing options...
zoothorn Posted July 30, 2018 Author Share Posted July 30, 2018 The foam monster's cut roughly flat, but Ive been a muppet & forgot the batten addition at front. Bugger- this sill bed is prooving the trickiest bit. What the heck do I do? the surface is so rough its not feasable to fix the PB onto it surely.. Ive also got to add the batten which will mean building it up again with something/ what Ive no idea, or trying to trim -along/ longways- a batten to get it to 1" > then cut the foam down a fraction. I'm not happy about it as a base for the sill to fix to- it seems just not right it seems to me Do I have any other ways of doing this?. Link to comment Share on other sites More sharing options...

Hand on heart you could stick insulated pb down to the brick with low expansion foam. If you're really set on doing something more solid though... Put another batten in then to form a lip. Your 27mm insulated pb will sit on that at the front and screw to it. Screw from the side thru the other battens as @PeterW says. Pilot drill it so the wood doesn't split at the end. Then stick it as best as you can along the wall with some No Nonsense stuff. Let it go off. Dig out some foam to expose the "bricks" . Give it a Hoover. Soak with pva (or sbr) mixed 5:1 with water. Kid's craft glue if you're stuck even. Mix up a strong sharp sand / cement mix say 4:1 using the same 5:1 pva mix. Not too runny, and pack it in and level off. Have a beer. With the drugs you're on it should be a ride! When the cement has dried loose fit your 27mm insulated pb. Try and make sure it sits level to the window horizontal lines. Blob with No Nonsense grab adhesive and weight down. Have a beer! Edited July 30, 2018 by Onoff Link to comment Share on other sites More sharing options...
Onoff Posted July 30, 2018 Share Posted July 30, 2018 My weapon of choice for trimming foam. Old bread (?) knife. Wavy one side and serrated the other. I seem to remember it was forked at the end at one time. It's seen use for weeding before! And my other weapon of choice. Reminds me of the Party Sevens as a kid! A winning combination!

zoothorn Posted July 30, 2018 Author Share Posted July 30, 2018 I wish I could have a beer.. havent had one since mid world cup/ not allowed to. I think its looking good.. but worried about once the PB is on re. the contours over my battens a bit. once Ive got this bloomin window area done. driving me mad. Can you see tho the flat splat isn't brick or old mortar.. its the foam beast, cut down. I don't alas have anything solid to glue anything onto. If I went sharp sand/ cement > do a mix Id have to buy a bucket of sand min & a bag of cement > 95% left.. And costwise too just for this.. What I need is some stuff I can as you point to (I think?) pour in & it'll level itself. Is there not some sort of small bag of gubbins, fit for the job?
