FIBERED FOUNDATION COATING
DISSCO 520 is a fibered asphalt base coating designed for use as a below
grade dampproofing compound for residential and commercial applications.
Manufactured from industrial-grade blown asphalts, high grade mineral
spirits and select mineral fibers, the DISSCO 520 is designed to keep
ground moisture from penetrating the foundation wall providing corrosion
protection and help eliminate the damp feeling common to most basements.
However, where a high moisture content, hydrostatic head or high water
table is encountered the coating should be upgraded to a waterproofing
compound such as the DISSCO 540 MASTIC.
520 will adhere to almost any type of material such as concrete, masonry
block, wood, steel, plastic, etc. Due to varying types of applications
the DISSCO 520 is available in four viscosities, and is available in packaged
sizes of 5-gallon pails, 55-gallon drums and in bulk.
DISSCO 520 is manufactured from high-grade industrial type blown asphalts,
mineral fibers and industrial grade mineral spirits.
DISSCO 520 can be applied as a one coat or two coat application, by brush
or sprayed with adequate airless equipment. It is recommended that the
DISSCO 520 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 800 psi
at the spray tip to achieve proper penetration, although it can be sprayed
with as little as 400 psi.
RECOMMENDED APPLICATION RATES FOR BELOW GRADE
One Coat Application
DISSCO 520 is ready to use directly from the container, no thinning or
heating required. It is recommended that a one-coat application of DISSCO
520 be applied at a rate of 2.5 to 3 gallons per 100 square feet of area
with a dry film thickness of approximately then 20 mils.

Two Coat Application
For a two coat application it is recommended that each coat be applied
at a rate of 2 to 2.5 gallons per 100 square feet of area with a finished
dry film thickness of not less then 30 mils. The first coat should be
allowed to dry for at least four hours before the second coat is applied.
