Can Seal-Krete Original Waterproofing Sealer be used on split-face block?
Due to the porosity and profile of this substrate, we do not recommend application of Seal-Krete Original Waterproofing Sealer. For split-face, decorative and fluted block, use Seal-Krete Heavy-Duty Waterproofer, a 25% solids version of Seal- Krete Original Waterproofing Sealer. This product was formulated specially for lightweight, low-density block.
