- Recommended Application Specifications
DISSCO 521 can be applied as a one or two coat application, by roller, brush or sprayed with adequate airless equipment. It is recommended that the DISSCO 521 be spray applied on below grade concrete and masonry structures so that a proper coverage can be achieved. An application by spraying causes the coating to be forced into the porous surface characteristic of concrete forming and masonry block. Spray equipment should maintain at least 600 psi at the spray tip to achieve proper penetration. While spraying pay close attention to surface irregularities to prevent shadows.
DISSCO 521 is ready to use directly from the container, no thinning is required. Heating of the product may be required in cold climates or during the winter months. It is recommended that DISSCO 521 be warmer than the surface it is to be applied to improve set time and adhesion to the surface. Ensure the surface to be coated is clean and dry. All honeycomb, rock-pockets, porous surface characteristics and/or surface irregularities should be parged or filled with a nonshrink cementitious grout or similar material compatible with the surface to ensure a uniform surface. It is recommended that masonry block be parged over the entire surface to be coated prior to dampproofing so that a better seal can be achieved. It is recommended that down spouts and surface irrigation be directed away from the structure and a functional perimeter drainage system designed by a registered engineer be installed by a qualified installer.
For a one-coat application it is recommended that the DISSCO 521 be applied at a rate of 1.5 to 2 gallons per 100 square feet of area with a finished dry film thickness of approximately 12 mils.
For a two-coat application apply the first coat at a rate of 1.5 to 2 gallons per 100 square feet of area. The first coat should be allowed to dry for at least four hours before a second coat is applied. Apply a second coat at a rate of 1 to 1.5 gallons per 100 square feet of area with a finished, two coat, dry film thickness of approximately 20 mils.
