FLEX SEAL has been mentioned in the past as a possible way to seal a wooden enclosure or to waterproof other structures.
One of my cement tortoise pools has been lined and re lined with fiberglass resin. It lasts about a year and then delamination starts.
So, this time I'm trying FLEX SEAL liquid.
My initial impression is that it's very expensive. I bought two tiny 16 ounce cans for about $40.
White. Because it was cheapest.
I applied it with a paint brush. It brushes on like thick latex paint. (In fact, that might be exactly what it is)
There is no real odor. No noticeable fumes. And it claims to be 100% non toxic. Wet or cured and totally safe for fish and animals.
That's GREAT news since about an hour after I applied the first can, one of my stubborn Redfoot knocked over a small barricade and walked through the area. That animal now has FLEX SEALed feet.
The stuff wipes/peels off just like latex paint. (Again)
Aside from the little pond now having footprints all through it. The job seems to be a success.
I'll get photos tomorrow when I either fill it up with water, or ad the other can.
From what I'm seeing. I don't think it's going to be durable enough to hold up to tortoise claws.
