Everbuild PUREX Foam Eater (Expanding Foam Remover) 250ml by Everbuild

it is over priced

We had a new radiator fitted and the pipework hidden within the wall. The plumber used an expandable filler and left yellowish remains on some of the radiator pipework. We found this residue unshiftable without doing damage to the radiator, so it has been baked on for two winters. I then came across this product by chance. Using multiple applications of this Purex foam eater, the residue has been gradually but completely removed and the white gloss finish of the radiator has not been damaged. A first class result!

This stuff worked for me on thin areas of foam overspray that had been left to harden for 18 months on a painted wooden window frame. Note that the foam doesn't just simply wipe off with the product. After leaving it to get to work for the recommended time you need to rub the area quite hard with a cloth to lift the foam. But it does disappear with a little effort. Note, it also has a tendency to remove any paint it comes into contact with.

Warning, perform a small 'tester' patch before use. I used this on a new oak front door that had several expanding foam stains (not my doing!) on both surfaces. Long story short, it worked okay internally but not so good outside and left stains marks on both sides. It looked as if there were damp patches where it had been applied. I had to very carefully sand it back by hand and reapply the rather expensive [osmo x12 UV Protect] oil. So it ended up taking several hours and £20 to put right. You could say It was my own fault for not doing a tester patch first, but either way.. you have been warned. The picture was taken a couple of days after application / removal. There are a lot of people here moaning about their husbands getting expanding foam everywhere, all I can say is don't mock until you have used the horrible stuff.. you think you can take your eye off it after 30 minutes but no.. that's when it starts going everywhere.

I ordered this as my hubby and I had some expanding foam fizz out from the upvc sills and surrounds we were replacing around our front door and windows. The expanding foam had dried and was looking really unsightly like a giant orange slug had oozed a streak down the front door and sneezed all over the window frames. We'd tried a few things on tester patches where they'd not be noticed and found nail varnish remover would not work on dried expanding foam (that discoloured the upvc on the small tester patch we did, taking the sheen off the upvc and making it look matt white and didn't lift a thing off), tried gently scrapping away at it (which did take some flecks off but left very fine though barely noticeable scratches, we were worried that in time the scratches would gather dirt and end up looking just as grubby), and we tried soaking WD40 into the dried expanding foam before trying to peel it off the upvc (which unless you want to spend a few months on this process it would work but even watching paint dry would be a more fun prospect than this). The reviews on this Foam Eater are quite mixed but I thought I'd get some and give it a go anyway - why not when we'd already tried other options. Ever hopeful we set about using it and we're super happy that it's worked! I give this review 4 stars because the info on the tin about how to use it can be a little vague but try to follow them as best as you can. The first time we used it, it actually appeared to do nothing! But we thought to ourselves, we have a whole tin of this stuff so let's try again. We did a test patch on just clean upvc to make sure it would not melt or discolour it and I suggest you do as well because though it was fine on our stuff, other upvc compounds might react differently. The test patch came out fine (we'd left a pea sized bead of it on for 2 hours before wiping it off) and then we tried a test patch on some cured expanding foam. The tin says leave it on for an hour and we did that but only to be disappointed that it didn't remove anything. So we thought we'd try again. This time instead of applying it quite thin and sparingly we lashed it on good and thick with a decorating scrapper/ palette knife (which we found great for mixing and stirring the tin up with no mess if you use a small one that will fit into the tin) and rather than leaving it for ONE hour, we left it for FOUR hours. This was actually by accident first time as we got caught up with some other tasks of renovations we were doing in the house and only after about four hours did we think "Heaven's the expanding foam eater goop might have eaten the window sill off!" but thankfully, the upvc was quite alright and after wiping away the goop with a sponge with warm water we found that low and behold - no more dried cured expanding foam! HUZZAH! So it did work in the end but you need a little bit of patience with it. If it doesn't work first time then it's definitely worth trying again but leaving it on longer and really well coated. We used this stuff on quite a crisp, chilly and dry day (which was around 12C-15C) so if anyone buys this to use in summer I would think a good word of caution is to watch it carefully and don't just go right for the full four hour whack we have resorted to as it might be likely to work faster in warmer weather.

So I got some expanding foam on my brickwork and needed something to remove it. I tried acetone which had a bit of an effect but not much so I decided to try this product taking into account the mixed reviews. I tried it on a spare brick I had too and it didn’t stain as such but left a white residue which I needed to apply lots of water to to remove - but I could cope with that. So I applied it and left it an hour like it said. Instead of a wet cloth I used a wet toothbrush to remove it. And the result......absolutely no effect whatsoever....the foam was still there despite me stripping it down as far as I could get it to start with. Now I was left with white residue to clean. In the end I had to lightly sand the brick and it doesn’t look too bad. I complained to amazon and they were so good and gave me a refund. I’d be cautious about this product. I think it depends what surface you want it removed from. My bricks were rough faced.
