BIO-FILL™ 456 is a specially designed void filler and repair compound used for filling and leveling concrete surfaces damaged by physical or chemical exposure. BIO-FILL™ 456 is based on liquid epoxy resins, aliphatic polyamine curing agent and proprietary pigmentation and additives to yield a strong yet lightweight filler with excellent chemical and physical properties and outstanding adhesion even to wet concrete.
BIO-FILL™ 456 may be applied up to 2″ thick on vertical concrete surfaces with no effective thickness limit on horizontal applications. A thin, “block filler” application is easily made using straight edged spreaders. BIO-FILL™ 456 will not soak into porous surfaces such as cinder block and has excellent “bug hole” filling properties. It may be left uncoated or may be over coated with finish coats such as epoxies, polyurethanes or latex. The formula is “Not Regulated” by IATA, IMO and USDOT and ships without complication as “NonHazmat”.

BIO-FILL™ 456 is formulated without solvents. This makes it possible to apply any thickness without shrinkage. It will adhere to almost all clean surfaces including previously coated surfaces and such solvent sensitive substrates as asphalt. In order to obtain good adhesion, it is necessary to provide a firm clean substrate. This may be achieved by abrasive blasting, chipping, high pressure water blasting and so on. Residues of oil or dust and debris will impair adhesion and must be removed before application.
BIO-FILL™ 456 is supplied in pre-measured containers to yield a 1/1 mixing ratio by volume. The Black epoxy base and White curing agent blend to produce a Haze Gray finished material. Streaks of black or white indicate inadequate mixing. Small amounts may be mixed by using plastic cups or similar containers to measure two volumes of base to one volume of curing agent. Whenever possible use heavy duty geared mechanical mixers to blend the curing agent into the epoxy base, mixing large volumes of heavy material by hand quickly becomes tedious. The product may be poured or applied immediately after mixing without waiting for a “sweat-in” or induction time.
(A) Horizontal areas: Pour the mixed components into the prepared void area taking care to ensure that the BIO-FILL™ 456 will be able to displace trapped air or water. It will be helpful to paddle the mixture around the void space if there is a possibility that trapped air or water is present. BIO-FILL™ 456 is less dense than water so although it will bond strongly to damp concrete, it will float above standing water preventing a bond.
(B) Vertical areas: BIO-FILL™ 456 may be applied up to about 2″ thickness over vertical concrete surfaces. Apply the mixed material against the concrete using a straight edged spreader or similar tool and press into the void to be coated in order to “wet” the interior surface. Excess product is easily removed and returned back to the pot or spread out in a thin layer using the straight edged spreader.
BIO-FILL™ 456 is formulated using entirely liquid resins in order to avoid the use of solvents. Substantial polymerization has to take place before hardening becomes apparent. The rate of the polymerization reaction is very dependent on ambient temperature and will be quite slow at temperatures below about 55°F, (13°C). If low temperature use is anticipated and curing rate is critical an accelerator may be used which will speed up curing at the expense of pot life. At 80°F, (27°C), the mixture will show a significant exotherm about 50 minutes after mixing and will be set firm but elastic overnight. The curing will proceed for several days ultimately yielding a resilient, very tough plug or surfacing.
The cured product may be over coated with a variety of topcoats if desired. Materials such as BIOGARD™ 251 will give an extremely durable surfacing ideal for flooring or secondary containment applications. Where strictly cosmetic effect is desired it is possible to overcoat with latex, vinyl-acrylic or similar paints.
