FX-263 was used in the following case studies:

Repair New York City Parking Garage

DESCRIPTION:

FX-263 Rapid Hardening Trowelable Mortar with Migratory Corrosion Inhibitor is a one component trowelable patching mortar designed for overhead and vertical use. FX-263 is a special blend of fiber reinforced rapid setting cement with silica fume, polymeric compounds and aggregates which achieves structural properties in a short time. FX-263 is ready to use with just the addition of clean water which activates the modified cement mortar.

ADVANTAGES:

Meets specification of Virginia DOT.
Very rapid hardening cement patching material for vertical and overhead use
Single component—just add water to activate modified cement.
Excellent bond to clean concrete and masonry surfaces.
Can be applied in layers up to 3" thickness.
Consistency of the material is controlled by the amount of water added.
Not a vapor barrier.
Fiber reinforced for high tensile strength.
Extremely good abrasion resistance.

WHERE TO USE:

Overhead and vertical patching mortar for: broken or spalled concrete, pavement, curbs, beams, underside of concrete bridges, repointing mortar, stucco. Ideal for setting beds on uneven surfaces where good gap filling properties are essential, and ideal for rapid setting of brick pavers and tiles outdoors or indoors.

SURFACE PREPARATION:

Remove all dirt, grease, oil laitance and curing compounds from concrete, mortar and stone by sandblasting or mechanical roughening. On metals, remove grease, oil, rust and mill scale by abrasive blasting or wirebrushing.

MIXING:

Pour 135 fluid oz. (4.0 L) of water in pail or mortar mixer. In pail, mix with a slow speed drill and paddle, while adding FX-263 powder slowly to avoid lumps. (Do not over mix; three minutes is sufficient.) If a more plastic consistency is required, add additional water to mix. Should small quantities be required, be sure to use smaller quantities of water. Masonry surfaces or other absorbent surfaces should be dampened but free of standing water. For economical purposes when lift thickness exceeds 1 inch, dry pea gravel or #7 stone may be added to the grout mix.

APPLICATION:

Lowest application temperature is 40°F (4.4°C) at the time of application. Be sure mortar is mixed thoroughly to a uniform consistency. Trowel FX-263 Rapid Hardening Trowelable Mortar with Migratory Corrosion Inhibitor in prepared area and allow mortar to stiffen, then produce desired finish by using float or rubber gloves, forcing mortar in voids. If steel trowel finished is required, wet trowel with water. FX-263 should be protected for first 24 hours after placement from oil, acids, and alkalies. Protect from wind and heat for the first 24 hours. On very porous or weak surfaces, use FX-752 Bonding Agent as a primer. To improve bond, apply FX-752 Bonding Agent at a rate of 100 square feet per gallon (9 m²) on smooth surfaces, 60 square feet on rough (6 m²). Must apply topping while FX-752 is tacky; if dry, recoat. On large surface areas, the use of a good curing compound, meeting ASTM C 309, Type I, such as FX-15, may be necessary.

LIMITATIONS:

Store in cool, dry place. Material should be stored at temperature of 40°F (4.4°C) or higher.

PACKAGING:

50 pound multi-wall polyethylene lined bags and 50 pound (22.68 kilo) pails. Yield is approximately 0.45 cubic feet per bag. 50 bags per shrink wrapped pallet.

SHELF LIFE:

12 months in dry protected storage. All materials must be stored indoors.

CAUTION:

Cement powder or freshly mixed concrete, grout or mortar may cause skin injury. FX-263 contains silica sand. Avoid breathing dust and contact with skin; wash exposed areas promptly with water. If any cement powder or mixture gets into eyes, rinse immediately and repeatedly with water. Get prompt medical attention! Use a NIOSH approved dust mask when needed.
