- Usage
Formulated for on site, two-coat spray or roller application, Hydro-Seal 75 forms a positive, high quality, integral protective barrier against mass water penetration.. When minimum down time, high pressure resistance, coating strength and longevity are major factors in choosing coating suitability, Hydro-Seal 75 can be specified for use on all types of damp interior or exterior, above or below grade masonry surfaces including concrete, brick, various types of masonry block, mortar, stucco, adobe, cast-stone, or sandstone.

- Coverage
This chart assumes the masonry to be in good general condition. Old masonry, however, often becomes more porous after long exposure and weathering. Steam cleaning, sandblasting, and acid etching will also make masonry more porous. These recommendations will have to be adjusted on the job to the condition of the masonry. When estimating coverage, allow 10% for overspray. Winds of over 15 MPH will result in further loss of material.
- PACKAGING
Hydro-Seal 75 is available in 10 gallon kits (2 five gallon pails marked A and B), 6 gallon kits, 1 gallon kits and in 55 gallon drums.. Colors available include white, gray and beige.
- Advantages
Resists Hydrostatic pressure Interior, below grade walls with stands hydrostatic pressure of over 40 PSI without leaking, exceeding Federal Specification TT-P-001411.; Water Resistance Will effectively protect substrate and prevent the absorption of exterior moisture as tested using Wind Driven Rain Machine in accord with Federal Specification TTC-001224; Efflorescence Control The passage of water through masonry units dissolves free lime and other salts including sodium, calcium or potassium, carrying them to the outer surface. The salts then crystallize to form efflorescence, an objectionable discoloration of the surface. Hydro-Seal 75 prevents the major cause of efflorescence deposits.; Alkali Resistant Excellent resistance to alkalis in accord with ASTM D-543.; Non-Oxidizing Does not contain silicone or oxidizing ingredients such as marine oils, or vegetable oils. Will not oxidize in accord with ASTM D-822.; Flexibility Retains ability to flex with movement of the structure. Passes 1/8th" Mandrel test as per ASTM D-822; Solvent Free Contains water extended resins that cure by catalytic polymerization.; No unpleasant odor Since there are no toxic or odorous solvents in Hydro-Seal 75 it can be used in occupied areas with no discomfort including schools, homes, and hospitals. It is also ecologically safe and acceptable.; USDA Approved Hydro-Seal 75 is USDA Approved for use in food preparation areas.; Vapor Transmission Does allow some vapor transmission in accords with ASTM D-1653. Perm 1.75; High Solids Solids are 56% by volume. The high resin filler ratio give Hydro-Seal 75 superior waterproofing properties over a prolonged period of time. Thixotropic additives allow for uniform vertical spray applications with high film builds up to 30 wet mils without sag, surface checking or mud cracking.; Labor Saving Sprayed with a minimum 2/3 gallon per minute capacity pump (Graco 433 or equal). Use a minimum .019 or .021 tip and 3/8" I.D. material hoses.; Cleanable May be easily cleaned with normal cleaning compounds.; Fast Dry @ 72 degrees, 50% relative humidity Hydro-Seal 75 sets to touch in one hour; dries hard in 3 hours - with a total cure in four days.; Pot Life Mixed material will last about 45 minutes @ 72 degrees.; Shelf Life Hydro-Seal 75 will last 6 months in unopened containers.
