- Coverage
Approximately 220 square feet (ft²) per kit at 10 mils dry film thickness (DFT). Allowances should be made for waste.
- Surface Preparation
Steel: Apply only to clean, sound surfaces. All metal surfaces should be degreased and decontaminated prior to abrasive blast cleaning. For immersion service, surfaces should be abrasive blast cleaned to a white metal (NACE No. 1 or SSPC SP 5) condition with a dense 2 to 4 mil anchor profile depth.
Concrete: Do not apply this product directly to concrete. At a minimum, concrete surfaces should be primed with MADEWELL 927 Penetrating Epoxy Primer. Deteriorated concrete may be restored using MAINSTAY ML-72 or ML-72F Sprayable Microsilica Restoration Mortar followed by MADEWELL 927 Primer
Rough Substrates & Deep Voids: Extremely rough or deteriorated concrete could be more economically smoothed and/or repaired using MAINSTAY ML-72 or MAINSTAY ML-72F.
Smooth Minor Surface Irregularities: Use MADEWELL 1312P Sprayable Epoxy Putty to smooth minor surface irregularities (less than 1/8” deep).
- Priming
Not required for steel surfaces. Concrete surfaces should be primed with MADEWELL 927 Primer.
- Mixing Ratio
Mix components at a volume ratio of 3 parts A to 1 part B. Whenever possible, avoid mixing partial kits.
- Mixing
This is a two component system. All components (liquids A and B) should be between 70° Fahrenheit (F) and 90° F prior to mixing. The entire contents of each component should be thoroughly mixed individually before combining separate components together. If it is not possible to mix an entire kit, pour carefully measured quantities of both components into a clean container and blend thoroughly using a power agitator, such as a Jiffy® mixer, and a high strength industrial drill for 3 minutes. Do not mix more material than can be used within stated working times.
- Working Time
Approximately 15 minutes at 70°F. Working time will be extended somewhat at lower temperatures and shortened when higher.
- Application
This product is to be applied by trained workmen using specialized equipment. MADEWELL 525 can be applied by conventional airspray and or rolling with a mohair roller.
- Number of Coats
Depends on service requirements. Generally speaking, linings or coatings for immersion service should be holiday free. The number of coats required to attain a holiday free lining or coating may vary depending on surface profile or roughness. Single coat applications should be done in multiple passes, each made at right angles to the last.
- Cure Time
Foot Traffic: 4 hours at 75° F.
Immersion Service: 24 to 72 hours, depending on the chemical service and cure temperature.
- Clean Up
Use Methyl ethyl ketone (MEK) to clean application equipment. Skin should be cleaned using warm, soapy water or commercial hand cleaner.
- Recommended For
Most concrete, wood, and steel surfaces, including:
- Aquarium decks and floors
- Garage floors
- Commercial floors
- Warehouse floors
