Hello all.

Right, I'm going to sort the spongey floor in my 92 Avondale Malvern. It's right in front of the sink/cooking area.

I'm looking to use the One Shot Floor delam kit as stated in the topic, anyone used this stuff and did it work ok?

Seems to me it would be easier to use but thats not much consolation if it doesn't work so well.

As seen on the bay item no. 320198193758

Cheers

i purchased 2 bottles last year for my daughters coachman.it does the job. it does just under a mtr per bottle .cant say if its as good or better than 2 pack as ive never used it.i also did part of the floor with expanding foam it really does do a good job.

Hi TbirdX , welcome to UKCS , here's some info that may be of help delamination .

Did you try the one shot glue?

Has anyone else tried it?

I am guessing that without a hardener it will take a while to set.

Cheers

The one shot glue is a MCPU - Moisture Cured Polyurethane.

The panels would be bonded with either a single pack or twin pack version of this during its original manufature.

The only poroblem with it, apart from the fact that you cannot get it off your hands, is that it is moisture cured and must be applied in a thin coating. If you have a hole in the floor either from damage or a pipe in there, you might get an adverse reaction. i.e. it will cure around the outside ofthe 'lump' of glue, sealing it away from moisture. The glue within this sealed lump can remain liquid for months until you step on it funnily, or something happens (speed bump in the road) to break the glue bubble. It can then start to cure this bit.

MCPU's expand when they cure so you MUST ensure that you have weighted it down.

In the case of the glue bubble, you might get a lump appear in the floor many months after your repair. Then it's a floor out job to repair

sorry but the one shot i used was not a moisture cure like gorrila glue that does expand. the one shot i used was called 2525 green and is a resin.

Ooohhhhh yes it is LOL

Single pack glues either cure from solvent (including water) evaporation, a reactant on one surfcae, or are moisture activated.

2525 is made by Chemique as is XP2525, a single pack MCPU with a green colourant. I don't know why they make it green?

Gorrilla Glue, expanding foam, LTM4, Bison single part PU, Purocol, and this 'one shot' are all based on similar technologies where the Polyol is activated by an isocynate hardener which has been reacted with it. The moisture kicks the isocynate off, and hey presto, according to the amount of C02 released, is how much it foams.

PUR is PolyUrethene Resin (although some prefer to name it PolyUrethane Reactive)

Oooooooh no it isnt.yes it is i just been outside dampened two pieces of timber wacked some 2525 green on it15 mins later no sign of it expanding.so im thinkin tee hee got ya.then 10 mins later it started to very slightly bubble and expand.its not as vicious as gorrila glue. so my appologies you were right i was wrong.but i bet i know more about plastering than you do lol.

I bet you do.

Did you really go to all the trouble with the 2525? LOL

yes needed to know as im doing a section in my avondale.i used it in my daughters coachman which was very damp so that must have set it off.so with mine i will have to drill the holes and squirt water in.wish i had the 2 pack now doh.but if you hadnt told me it would never have set so thanks for that.

well i have now used the one shot in my avondale.unlike my daughters coachman where the polystyrene had dissintigrated  (think thats how you spell it} mine had just parted company.i drilled the holes but because there was no cavity the one shot just filled the holes i had drilled.i bought wooden dowels from b&q as i filled each hole with the one shot i put in a dowel,the dowels were in a pan of water  because quattro says it needs moisture to cure.i have not used 1/2 a bottle to glue the floor where it worked in my lasses caravan i dont think it will in mine.will let you know tomorrow.
