NON-FIBERED FOUNDATION COATING
DISSCO 521 is a nonfibered asphalt base coating designed for use as a
below grade foundation dampproofing compound for applications where a
high water content is not present. DISSCO 521 is designed to prevent moisture
and/or dampness that may be present in the soil from penetrating a foundation
wall providing corrosion protection and preventing the damp or musty feeling
common to many basements. For applications where a high moisture content,
hydrostatic head or high water table is present it is recommended to upgrade
to a true waterproofing compound such as the DISSCO 540 Mastic. DISSCO
521 will adhere to almost any material such as concrete, masonry block,
wood, steel, plastic, and many other surfaces. DISSCO 521 is manufactured
from high grade industrial type blown asphalt and industrial grade mineral
521 can be applied as a one or two coat application, by brush or sprayed
with adequate airless equipment. It is recommended that the DISSCO 521
coating 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. It is recommended that masonry
block be parged (cement grouted) prior to dampproofing so that a better
seal can be achieved. Spray equipment should maintain at least 600 psi
at the spray tip to achieve proper penetration, though it can be sprayed
with as little as 100 psi.
RECOMMENDED APPLICATION SPECIFICATIONS
DISSCO 521 is ready to use directly from the container, no thinning or
heating is required. It is recommended that a one coat application of
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 two 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
and shall achieve a two coat, dry film thickness of approximately 20 mils.
