Hi Les,
Thanks for your question. We recommend mixing Drybase TS-PLUS with Drybase 5-Bar Waterproofer for ponds.
Once TS-PLUS has set (as with any cementitious coating), it is no longer corrosive to bare skin.
Once applied, you must allow the coating to fully cure over 7-28 days, then wash the finished surface to remove any residue before refilling the pond.
If you have any further questions, please get in touch via 01403 210204 so we can advise you further.
Is Drybase TS-Plus suitable for repairing cracks in a concrete pond?
The small print on the packaging states that when mixed with water it becomes corrosive.
This begs a few questions: First how persistent is the corrosive effect. second Is the toxicity sufficient to affect aquatics if used to repair cracks in pond concrete?
