discussion Fibreglass gone tacky

[slupanter]

Hi guys

I've been building a large fibreglass hull. The hull was bought pre moulded in fibreglass. I've fill the centre with No More Nails and now the certain patches have gone very tiniest tacky. Could this just be the moisture escaping as the No More Nails dries or is it a reaction between the fibreglass and No More Nails?

Alexander, No More Nails and the like are a kind of acid, so I would put money on your second suggestion....A reaction.

Best use fresh fibreglass/resin or body filler for any filling or bonding on the hull interior.

If the sticky is on the outside gel coat, you can get gelcoat in a tube(various colours) Use it to repair the affected area after removing the offending sticky......

The sticky areas should go hard again in time....if not scrape it off and use the above stuff.

Others could well be along soon with their own ideas too!

Cheers,

Ron

Bugger!,

If I get what No More Nails I can out can I save the kit?

I take this is a boat hull? The reaction is the no-nails, not suited for applications like this, you need a fibre-glass repair kit to do the job properly. Clean out as best you can and sand back so all clean then repair using the fibre glass kit.

Thanks,

I need to fill a large area of the hull. What is the best Fibreglass filler?

No More Nails is rubbish!

 

[slupanter]

So what's the best why to fill it?

Something like this will do the job, or you can get separate items from any good motor-factors.

Try Davids P38 or P40. Both compatible.

One is a 2 part filler, the other is Fibre Glass used regularly in the motor body repair profession.

Both can be purchased at the likes of Halfords (expensive) or ant car body repair suppliers.

I have used both on my plywood/balsa/fibre glass boat hull.

The P38 is easily sanded and can be primed with any type of primer!

THANK YOU THANK YOU! All of you. I got the no more nail rubbish out and clean the kit with warm soupy and a tooth brush. No sign of any tackiness.

So, P38 it is then.

And that's safe to use on my fibre glass hull?

 

[eddiesolo]

Yes, as Gregg points out P38 will be okay to use, many use it on their boat hulls.

Great thanks all.

So what can I use on the outside to harden the fibre glass up and remove any tackiness?
