| You can have a sealent mixed in the concrete, a variety of mortor spreads that are easy and cheap to apply youself, products like "sure-wall"/stucco-like products, pool paints, exopy paints and other paints, concrete sealents, variety of chlorinated rubber products (intended for pools), CIM, Herco, etc. Most of these easy to apply and very cheap. Poly has a wider selection of applications than just a sealent for gunite ponds. I would probably use Herco. |
