Best adhesive wood to fibreglass any ideas please.

[shawbags]

Hi all,i have recently aquired a Citroen C15 motorhome that needs a little updating inside and i am looking for any idea's on the best adhesive to bond timber to fibreglass to support the cieling lining,is no nails any good and if so what make or any other ideas you might have that works well and won't break the bank,cheers Shawbags.

gripfill,its what all the others try to copy,tubes are cheap,try a small piece of wood overnight then see what it takes to shift it

i use ct1 stick like sh 1 t to a blanket

Fibre glass resin and tape. It is what some boats are made with, ie mirror dinghys.

Epoxy resin. Araldite or West 'frinstance

If it was a boat we would use various methods to bond timber battening to a GRP hull.
These include glassing in with chopped strand mat and resin , Davids p40 for small areas,or sikaflex (screwfix). If an area is subject to particularly high loadings we might use epoxy resin with some microfibres (Google Robbins timber or try sp resins also Aquafax now supply epoxy).
My feeling is that for a motorhome sikaflex is probably the best option, but remember that battening out is like the foundations for a house, just because it is hidden doesn't diminish its importance, it should be neat and accurate and when the lining is in and the fit out complete it almost shouldn't matter if the battening comes detached ( with emphasis on almost) as the entire work should lock together to create an interlocking whole.
Good luck

From my experience of Gripfill I wouldn't use it as it isn't very flexable and proberbly not adhere to the fibre glass.
I would go for something more flexable.

Like stan I would use ct1 saw it at a demo filled a paper cup cut it with a Stanley from o/s sealed it with ct1 then did it again and sealed the cup from the inside, also had a large heavy concrete block with wood glass plastic ct1 bonded to it and an handle glued on each with ct1 and picked up very impressive

Yeah Ct1 would be ok but small word of caution for silicone based sealants/adhesives.
When using these they tend to be very messy and get spread around a lot (as do many of the alternatives)so you need to be careful that they are not spread around on clothing or your hands etc as they can cause terrible problems with paint or internal finishes. We dont use them for this reason but its true they do work well as adhesives

ct1 is not silicone based ! stan

 

[Martin P]

Ha ha jokes on me then!
Well I actually used some ct1 last week and it looked like silicone , smelt like silicone and behaved like silicone.
I used it as a panel adhesive and it worked very well
I noticed it had an ingredient list on the tube so I am going to investigate this further as i suspect there may still be silicone in it of some form
Just goes to show you learn something new every day

and paintable

One of the polyurethane (single pack) adhesives such as Sikaflex (but need to get the correct one) will do the job. Adhesive, not sealant.

Don't make the mistake of squeezing the joint close together. 2mm adhesive thickness is about right and can be achieved by cutting thin strips of inner tube and using them as spacers. They can either be left in, or once the adhesive has started to cure, pulled out from one side.

Surface preparation is essential. Clean and abrade and use the correct primer if you want it perfect, but not all applications need the primer.

My OKABox is held together with adhesive and has so far survived thousands of miles of corrugations and potholes with zero failure.

Ok gents thanks for your replys,i think i might go for CT1,two 4-5 foot lenths of light timber only need to hold aproximatly 2 pounds in weight,cheers Shawbags.

 

[Martin P]

I had a play around with some ct1 today and it does seem to be pretty good stuff. I was particularly impressed by its fast grab with virtually no slide even on vertical surfaces. Quite pleased about this as I have 2 boxes about 20 tubes (long story) of the stuff
Good luck with your build

Ct1

I must get some of this CT1 as I have NEVER been able to glue anything sucessfully 'except wood using PVA'.
This could be a new beginning for me on the glue scene....:dance:

 

[Martin P]

Glad your'e sticking with it

Ct1

I think i will go with CT1 as it will only be holding a couple of pounds in weight,thanks for all the info gents,i will put the photo's of the job from start to finish when it is done but i will have to become a full member first,cheers Shawbags.
