- Coverage
Approximately 16 square feet (ft²) per gallon at 100 mils; 72 ft² per 4.5-gallon kit at 100 mils. 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 Mortar.
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. Apply MAINSTAY DS-5-S to primed surfaces when the MADEWELL 927 Primer has cured dry to the touch (but as soon as possible thereafter to avoid contamination of the primed surfaces).
- Mixing
This is a two component system. All components (liquids A and B) should be between 70°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 45 minutes at 80° F. The working time will be extended at lower temperatures and shortened when higher.
- Application
This product is to be applied by trained workers using specialized equipment. Both components must be preheated between 70º F and 90º F prior to application. A 56:1 airless spray pump with an air input pressure of approximately 45 pounds per square inch (psi) may be used to feed material through up to 50' of 3/8" diameter hose to a standard airless spray gun with a 0.031" - 0.035" reversible tip. It is recommended that 30 mesh in-line strainers/filters be used. Other equipment, such as whip hoses, heaters, or plural component equipment may be employed. MAINSTAY DS-5-S can also be applied by brush or roller. MAINSTAY DS-5 can be applied to MAINSTAY ML-72 or ML-72F within one to two hours after the MAINSTAY ML-72 has been placed and finished (when the MAINSTAY ML-72 or ML-72F has just become firm to the touch).
- 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: 24 Hours at 70°F
Immersion Service: 24 to 72 hours, depending on the chemical service and cure temperature.
- Clean Up
Use Xylene or methyl ethyl ketone (MEK) to clean application equipment. Skin should be cleaned using warm, soapy water or commercial hand cleaner.
- Recommended For
Steel structures in industrial environments, such as:
- Tanks
- Trenches
- Sumps
- Floors
- Clarifiers
- Scrubbers
- Digesters
- Pulp and paper mills
- Chemical processing plants
- Mixing Ratio
Mix components at a volume ratio of 2 parts A to 1 part B. Whenever possible, avoid mixing partial kits.
