Epoxy Concrete Floor Patching & Topping Compounds

FLEXI-TOP 500 & 555 are heavy-duty, 100% solids, odorless epoxy mortars far patching and topping of commercial, institutional and industrial floors.

FLEXI-TOP 550 is a self-leveling surfacing system providing heavy-duty protection at l/8" to 1/4" thickness or more. Blended with select aggregates, it forms a fluid mixture which easily spreads with a V-notched trowel or squeegee. Upon curing, it forms a dense, non-porous flooring that resists chemical and water penetration, dirt pick-up, and heavy traffic. It may be sealed with a number of protective topcoats for improved skid resistance, gloss and color retention.

FLEXI-TOP 555 is a versatile trowel-applied mortar used for patching or toppings of 1/4" or more. Blended with specially graded aggregates, it forms a dry, trowelable mortar that can be applied by hand or power trowel. This mortar is then grouted and sealed with 100% solids resins to eliminate porosity and produce a dense, non-porous, slip-resistant finish.

* Working and cure times are affected by temperature and mass. For reduced cure time, see instructions on addition of FLEXI-SPEED 599 Accelerator.

APPLICATION:

1. Conditions & Surface Preparation:

a. Substrates must be above 55⁰F, dry, and free from hydrostatic pressure, moisture vapor transmission, paint, curing compounds, oil, dirt or other materials which could hinder adhesion. For colder temperature (39⁰F - 55⁰F) a similar system with better low-temperature curing properties can be recommended by your Edison Coatings Technical Representative.

b. New concrete should be cured 30 days minimum, and must be acid-etched or mechanically abraded prior to coating. Old concrete should be inspected for structural soundness and mechanically prepared prior to topping.

c.Wood surfaces must be clean, porous and free from wax, varnish, or other materials.

d. Metals must be clean, rough and free of oil, coatings, rust and scale. Abrasive blasting is recommended prior to topping.

2. Application:

a. Mix and apply primer 30 minutes to 8 hours before topping. Primer may be neat resin/hardener or special primer as recommended by your Edison Coatings Technical Representative.

b. Mix resin and hardener at specified ratio for 3 minutes. Add aggregate and mix until uniform in consistency. Spread material to desired thickness.

c. Finish-trowel as required. Minor trowelling inconsistencies may result from normal installation procedures, but will not affect system performance. Experienced mechanics are required to achieve best results.

d. Cure overnight, or add FLEXI-SPEED 599 Accelerator to accelerate curing to 4-6 hours. Level of addition: 8-24 ozs. per 4-gal. unit. FLEXI-SPEED 599 may be pre-added to hardener component without compromising stability. Do not add to uncatalyzed resin.

e. FLEXI-TOP 555 is then flood-coated with neat resin/hardener mixture, squeegee-applied to eliminate porosity.

f. For greater skid, impact and wear resistance, selected aggregate (quartz, silica, aluminum oxide, etc.) may be broadcast into the wet slury on 550 toppings, or into the resin flood coat on 555 toppings. Once cured, the resins will bond to this aggregate and make it an integral part of the system. To lock in this aggregate, a second application of resin/hardener is applied over the dry aggregate.

g. For greater gloss and color retention, chemical resistance, and easier cleaning, a seal coat may be selected for application over the topping. Consult your Edison Coatings Technical Representative.

3. Application Cautions:

a. Conditions affect handling characteristics of this system. Cool temperatures slow reaction and ncrease epoxy viscosity, making application more difficult. Store materials for 24 hours before use at 70-75⁰F, if possible. Warm temperatures accelerate cure and reduce pot life. Blend only as much material as will be used prior to gelling time at your particular working temperature.

b. Observe all warnings, procedures and guidelines contained in Material Safety Data Sheets for these products.

c. Heavy traffic, over time, may cause visible wear patterns, requiring a maintenance application of finish coat. Consult your Edison Coatings Technical Representative regarding refinishing procedures.
