Walttools has developed the Tru-Pac Mortar Convert Kit, which helps contractors perform vertical concrete work with a standard 60-pound mortar mix found at home improvement stores.
After the product is added into the mortar mix, the mixture can be stamped almost immediately after it is smoothed onto the surface. Its lightweight design allows for build-outs of up to 4 inches with the appropriate scratch coat, and its extended set time provides significant carving time for full-detail effects. It dries to a realistic buff gray and can be used with Walttools Tru Tint stains.
