How to Use HD-150

If concrete walls and floors are moist or wet due to water seepage through the pores of the concrete, then
XYPEX HD-150 can simply be applied with a brush to the concrete surfaces. However, if water seepage is
occurring through construction joints (where the floor and walls meet), cracks or other defects, then these
areas must be repaired prior to applying the Xypex coating.
WATERPROOFING CRACKS AND JOINTS
||Chisel or chip out a rectangular "U" shaped groove (not "V" shaped) along crack or
construction joint. For best results, groove should be approximately 1" wide by 1½" deep.
||Remove all loose debris from groove by flushing with water and scrubbing with a stiff
Fill groove with Xypex Patch'n Plug or other fast-setting hydraulic cement compound
available at building supply stores (to enhance its waterproofing characteristics blend 3 parts hydraulic
cement with 1 part HD-150).
||Apply HD-150 coating over the repaired area and to the concrete surface in accordance with directions below.
BRUSH APPLICATION OF HD-150
Once leaky cracks and construction joints have been repaired, the waterproofing of walls and/or floor can be
undertaken by applying a slurry coat of HD-150 to the concrete surface. To ensure best possible results,
follow the application instructions carefully (detailed application procedures can also be found inside the
container). Coverage for one coat is approximately 6 sq. ft. per lb.
||A clean, open-pore surface is required.
Remove any substance (e.g. dirt, oil, paint etc.) that could prevent the penetration of HD-150's
crystalline growth deep within the pores and capillary tracts of the concrete or concrete block. Smooth
steel-trowelled concrete (e.g. some floors) must be roughened or etched to provide proper "tooth and
suction" for the HD-150 treatment.
||Wetting the Concrete
||Moisture is also required for HD-150's
chemical ingredients to penetrate and crystallize deep within the pores of the concrete. Therefore, dry
concrete must be thoroughly saturated (soaked) with clean water before application of the HD-150 coating.
This can be accomplished by spraying with a hose or garden sprayer, or by filling a pail with water and
brushing the water onto the concrete surface. Excess surface water should be removed prior to application.
||Mix 5 parts HD-150 powder with 2 parts
clean water (by volume) until a thick creamy consistency is obtained (a paddle mixer on a slow speed drill
may be used for larger batches). Mix only as much as can be applied in 10-15 minutes. If mix starts to
set, agitate briefly but do not add more water. Protect hands with rubber gloves.
||Apply slurry mixture with a thick nylon
bristle brush (cement brush) or push broom for large horizontal surfaces. The mixture must be uniformly
applied and should have a thickness of 1/16" (1.25 mm). When a second coat is required (e.g. concrete
block walls), it should be applied after the first coat has set but is still "green" (less than 48 hours).
Spraying a light mist between coats may be necessary to prevent premature drying. HD-150 cannot be applied
outdoors in rain or freezing weather (see Limitations).
||The curing process is important for the
growth of the crystalline formation and proper hardening of the coating. Curing should begin after the
coating reaches an initial set and begins to dry (normally 1-2 hours). Cure by spraying the coating with
a fine mist of water or apply water from a pail with an applicator brush. Under most conditions it is
sufficient to dampen the HD-150 treatment three to four times a day for 2-3 days.
Care must be taken to prevent puddling of water over the HD-150 application on floor applications. In cool,
damp conditions, water curing of the coating may not be necessary. In hot dry conditions the treatment will
need to be dampened more frequently to prevent premature drying.
