Description:
AES-250 is tough and flexible protective coating for concrete. AES-250 is a 100% solid Polyamide epoxy resin used in applications where chemical and corrosion resistance is required.
Resistance:
AES-250 is highly resistant to acids, solvents, caustics, hydrocarbons, freshwater, and saltwater. It was developed to withstand extreme corrosive and abrasive conditions, with excellent outdoor durability.
Application Areas:
AES-250 is excellent as an anti-corrosive and protective coating for concrete floors and structures. AES-250 retains a resilient body, even after final cure. It can even be used under constant spillage and highly abrasive applications. AES-250 is used in commercial, industrial, and residential surroundings.
Preparation:
To begin, the surface should be etched to provide a profile or “tooth” for optimal adhesion. Surfaces must be cleaned free of grease, oil, wax, mastic compounds,
paint, waterproofing compounds, form release materials, and all other contaminants prior to application.
New concrete and masonry should not be coated for at least 28 days to permit the concrete or mortar to cure and dry out. Concrete should be visually inspected and tested for moisture content before coatingAES-250 will not develop optimum adhesion to concrete unless Latinate and other loosely bound materials are first removed from the surface. Latent must be removed by abrading. Shot blasting, scarifying, grinding, sand-blasting or other abrasive mechanical means are recommended. Acid etching is an option but not recommended because of environmental concerns or accidental damage to non-target areas.
For aged concrete, remove old coatings and/or other materials previously applied. Abrasive or mechanical means are recommended. Infiltration of oil, grease, gas, etc. into the concrete will retard adhesion. Contaminated concrete must be sufficiently removed or thoroughly cleaned with a cleaning agent appropriate for the removal of petroleum-based products. After the surface cleansing, continue on with directions for the new concrete application.
The preparation procedures above are general guidelines. Detailed preparation methods are available through SSPC at www.sspc.org or NACE at www.nace.org.
Mixing:
The mixing of Part A and B is very important! Material is supplied in two containers as a unit.
Agitate part B separately in container supplied before pouring. AES-250 has a (1:1) mixing ratio of 1 part “B” to 1 part “A”. Use a jiffy mixer to thoroughly combine both parts, mixing for 1 minute per gallon. Allow idle activation time for at least 2 minutes.
Thinning:
If thinning is necessary, use no more than 1 pint of Xylene per 2 gallon of epoxy. Thinner can only be added after activation process is completed. Thinning will extend pot life and retard curing time.
Application:
Apply AES-250 with a brush, 3/8” nap roller or airless spray equipment. Caution! Without the use of aggregate, AES-250 is slippery when wet. Apply only when air temperature is 40° F and rising.
DRY FILM APPLICATIONS
To get dry film of: Apply Sq. Ft. /gal.
8 mils 200 sq ft
16 mils 100 sq ft
DO NOT apply product heavier than (8 wet mils) on vertical surfaces. Heavy coats may be applied (up to 16 mils) on horizontal surfaces without danger of bubbling or pinholes in film. For heavier film, apply additional coats. Additional coats must be applied as soon as the surface is tack free or within 36 hours.
Clean Up:
Application equipment should be cleaned immediately with Xylene. Use white vinegar to clean hands and skin. Do not allow AES-250 to remain on tools! Once it sets and is cured, it is extremely difficult to remove.
