Be 100% sure that any repair mortars “do not” contain waterproofing admixtures such as polymers.

Radcon should absorb into the entire job including the patching material. This cannot occur if manufacturers are supplying mortars with their own water repelling materials contained therein.

Crystal growth mortars such as our Radmyx material are acceptable as they are compatible with Radcon and allow for necessary penetration after curing. This cannot occur where mortars with waterproofing additives exist in such products.
