BIO-SEAL™ 192 is based on pure liquid epoxy polymers and proprietary polyamine curing agents.
BIO-SEAL™ 192 is formulated with no volatile solvents and is so completely tolerant of water that it may be applied to damp or wet surfaces yet still function well as a reinforcing seal coating. Applications may be made using brush or roller with no especial ventilation requirements -odor during application is almost completely absent.
The standard “00000” version may be shipped “Non-Regulated” by air or surface -this material is ideal for most applications however it will yellow on exposure to UV light. A UV resistant version is available which uses the same epoxy base and curing agent BS 192-ll111B, this material ships UN1760, “Corrosive Liquid N.O.S.” PG III.
Used to seal and protect concrete, brick and similar surfaces against chemical attack and penetration by water leading to freeze-thaw damage.
REPAIR MORTAR RESIN:
Used to prepare repair and smoothing mortar by stirring in clean silica sand. Typical sand loading of 100 lbs sand per three (3) gallons of BIO-SEAL™ 192 resins will make about 7.5 gallons of a fully wetted, stiff mortar with excellent adhesion to cleaned concrete.

Bare Concrete: surfaces should be allowed to cure for a minimum of 20 days before coating. Excessive weak surface laitance must be removed by either acid etching or, preferably, abrasive sweeping before coating. Aged, uncoated concrete surfaces are best prepared by abrasive sweeping. Unless carried out properly acid etching can give unpredictable results due to inadequate etching or inadequate rinsing, for this reason abrasive blasting is the preferred method of preparation. Contamination by oil or grease should be removed, with an industrial degreaser before either abrasive blasting or acid etching.
BIO-SEAL™ 192 is supplied in 2 gallon kits of comprising epoxy base in a part filled 2 gallon plastic pail with curing agent packed in a part filled one gallon steel can. A “Jiffy” type mixer with a high torque motor is recommended for proper blending. Pour the curing agent into the base and mix for about 2 minutes taking care to stir in all base material from the edges and base of the plastic pail, unmixed material will never harden. No induction or “sweat-in” time is required and the mixed material may be used immediately.
When using with sand or other inert mineral aggregate as a mortar first thoroughly mix a two-gallon BIO-SEAL™ 192 kit using a 1/2″ “Jiffy” type mixer then pour this mixed material into a larger container such as a clean five gallon pail. Using the same Jiffy mixer add the desired mineral aggregate while stirring until the desired viscosity is obtained. As a guide it will be found that a two-gallon kit of BIO-SEAL™ 192 will accept about 66 lbs of sand to yield five gallons of a heavy but flowable mortar. This mortar can be used to smooth and level concrete, set safety railings into holes and so on. Addition of more sand will yield a stiffer mortar, which can be applied in heavy thickness without sagging. Fine sand makes a stiffer mortar than coarse sand. Sharp sand makes a stiffer mortar than rounded sand.
Pot life and reaction time is heavily dependent on temperature, as a general guide figure that each 18°F, (10°C), variation in temperature above or below 77°F, (25°C), will respectively halve or double the pot life and cure times.
Brush or roller application is straightforward and requires no special technique. Application on a floor is assisted by using a squeegee to distribute the BIO-SEAL™ 192 then backrolling to achieve an even coating. The material will thicken in cold weather and will be noticeably heavier at temperatures of 50°F and below. If permissible to use solvent it will be found that 5 -10% of lacquer thinner or MEK will greatly reduce viscosity in cold weather allowing much easier application.
CURING BEFORE SERVICE:
BIO-SEAL™ 192 will cure to a hard film within 24 hours and is suitable for traffic after this time. Allow at least three (3) days at 77°F before subjecting to aggressive chemical service from industrial solvents and similar materials.
