tacky fibreglass

[MUTL3Y]

Hi all,
can water be added to tacky fibreglass? or do you have to completely wait until the gel coat has gone off?
reason being is that we are up against a rising water table and it keeps lifting the resin and matting up by a long way.
so was thinking if the water is drained from below then resealed, resined, gelcoat and water in, then the water going in would stop the bottom from lifting.
but don't know if the tacky gelcoat would still set under the water? can anyone advise please (Bob:))
cheers

Ian,

The flowcoat has to cure completly. If you cover it and put heaters in there it should cure OK. Justin phoned me today, so I know what you are going through, but do get it to cure completly before filling.

I'd add that if you get any moisture into the resin before it has fully cured during any part of the process it will ruin the fibreglass - so you have to find a way to get the pond completely dry before you start and keep it that way until you finish. Also, you really need to get the temperature up to 16-18 degrees for the resin to cure properly as well.

The normal solution for a rising water table is an adjacent, slightly deeper hole with a sump pump pumping any water to waste. (At least for the duration of the glassing)

Hope this helps.
