FX-261

DESCRIPTION:

FX-261 Polymer Repair Mortar is a one component polymer-modified, cementitious repair mortar enhanced with silica fume. FX-261 can be pumped, poured, or placed in concrete structures. The polymer modified silica fume mix provides highly durable abrasion resistant concrete.

ADVANTAGES:

Easily mixed and applied.
Simple to use labor saving system.
High early strengths.
High compressive & flexural strengths.
High bond strength.
Compatible with coefficient of thermal expansion of concrete.
Superior abrasion resistance over conventional portland cement mortar.
Good freeze/thaw resistance.
Not a vapor barrier.
Not flammable, non-toxic.

Where to use:

As a structural repair material for parking facilities, industrial plants, walkways, bridges, tunnels and dams.
On horizontal, vertical and overhead surfaces.
On grade, above, and below grade on concrete and mortar.
Free-flowing repair mortar for hard to reach areas.
Leveling mortar.

SURFACE PREPARATION:

Steel surfaces should be abrasion blasted to a commercial metal finish as specified by the Steel Structures Painting Council SSPC SP-6. All work blasted shall be coated the same day with FX-408 Zinc Rich Primer.

Concrete surfaces shall be cleaned to remove dirt, curing compounds, existing coatings or laitance to provide a clean, sound bonding surface. Cleaning may be accomplished with FX-Masonry Cleaner and water blasting, acid etching and water blasting, abrasion blasting, or other methods that would achieve a similar result.

MIXING:

Mix (1) one gallon of water per 50 lb. bag of FX-261 Polymer Repair Mortar. Start with 0.8 gallons and mix in more to desired consistency.

APPLICATION:

For best results apply FX-752 Bonding Agent, and while bonding agent is still tacky, place FX-261 and thoroughly work into the substrate. For economical purposes when lift thickness exceeds 1 inch, dry pea gravel or #7 stone may be added to the grout mix. 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. Damp curing or use of a curing compound such as FX-15, that meets the ASTM C-309 standard, may be necessary to prevent rapid drying of FX-261. Curing compounds may need to be removed prior to coating.
