I've finished applying Xypex on one pond and about to begin the second one. This second pond raises an important question.
This other pond has several previous coats of RapidCrete Waterproofing (RapidCrete™ Waterproofing is a polymer-modified waterproof coating for masonry and concrete surfaces.)
How well will Xypex Concentrate generate the desired "non-soluble crystalline formation deep within the pores and capillary tracts of the concrete"?
I don't expect it would do as well here as with standard concrete. However, 50% effective would be great. I'd even live with 10%, but 0% wouldn't be worth the trouble.
Thanks in advance for you help. I'll keep my fingers crossed.
