I have a small plastic water tank that is cracking in multiple places. I'm
looking for a sealant that can be applied to the outside and encapsulate
the entire tank. Any ideas?
The only thing I've thought of so far is fiberglass resin. Does anyone
know if this will work?
Any help would be greatly appreciated.
thanks in advance
Nothing will stick to some of the plastics (polyethylene) used in tanks.
What if the tank was to fail? What is the potential damage? Is an unknown
repair worth the risk rather than a replacement? When plastic starts to
crack, it is going to continue to weaken.
The tank is rather small, if it were to fail, I'd have a quart of water on
my floor - no big deal. The replacement cost of the tanks is $200 - quite
a rip off.
Not sure what the tank is made of - hard, clear, molded plastic of some
sort. If I were to dip the whole thing into resin and make a shell, would
A quart is not such a big deal. Not like a 100 gallon tank where the feed
water will run as the float drops.
Clear is not polyethylene. Could be polycarbonate or crystal styrene. I'd
try a resin and fiberglass cloth as you originally suggested. That would in
effect make a new molded secondary tank. I can't imagine any one quart tank
being worth $200.
