Applications & Uses
- Applications
- Limitations
Applications should not exceed 250˚F.
- Substrates & Surface Protection
Remove oil & grease from the surface with solvent or a commercial cleaner, which does not leave a residue according to SSPC-SP1.
Abrasive blasting to a Commercial finish per SSPC-SP6 to obtain a 1.5–3 mil profile is preferred. For non-abrasive environments, Hand Tool cleaning per SSPC-SP 2, Power Tool cleaning per SSPC-SP 3 or high-Pressure Water cleaning per SSPC-SP12/NACE 5 WJ-4 is recommended.
- Application Equipment
- Conventional Sprayer - Industrial sprayers such as DeVilbiss MBC or JGA and Binks 18 or 62 having double regulated pressure pot, 3/8’ I.D. minimum material hose and a .070” I.D. fluid tip and air cap are recommended.
- Airless Sprayer - Sprayer such as Graco’s Bulldog with a 30:1 ratio and a 0.017” - 0.021” tip is recommended
- Power Mixer - Use only explosion proof power mixers
- Brush or Roll - Use a medium brush and short nap roller with solvent resistant fibers and core.
- Application Conditions
Material Surface Ambient Minimum 50˚F 50˚F 50˚F Maximum 90˚F 110˚F 110˚F Special reducing and application procedures are required outside these temperatures. Surface temperatures should be 5˚F above dew point to prevent condensation.
- Mixing & Reducing
- Mixing - Power mix each component, then blend Part B into the Part A and mix until uniform at the following ratio:
2 Gal. Kit 10 Gal. Kit M-250P Part A 1 gallon 5 gallon M-250P Part B 1 gallon 5 gallon - Reducing - Reducing is not required for most applications; however M-250P may be reduced up to 1 pint/gal. Reducer 1 - 250 is recommended for applications temperatures below 70°F and Reducer 2 - 250 is recommended above 70°F. Reducer 2-250 is recommended for overcoating inorganic zinc primers as well as for brush and roller applications of M-250P.
- Pot life - Four hours at 75°F. Less at higher temperatures.
- Clean Up
Cleanup with Reducer 1-250 or Reducer 2-250.
- Dry & Cure Times
The following minimum times are based on a 5 mil DFT and adequate air ventilation. Higher thickness and reduced air circulation increase drying times.
Surface Temperature To Touch To Handle Final Cure 50˚F 20 hours 48 hours 10 days 60˚F 10 hours 24 hours 5 days 70˚F 5 hours 12 hours 3 days 80˚F 3 hours 6 hours 2 days 90˚F 2 hours 3 hours 1 days M-250P can be applied in a wet-on-wet manner with itself, which eliminates the dry time between coats.
M-250P has a 30-day recoat window. It is imperative to remove chalk and surface contamination prior to recoating. High-pressure washing is an acceptable method of removing chalk and surface contamination. For applications requiring longer than 30 days, please contact Mascoat for recommendations.

Safety & Health
- Safety
For minimum protection, Mascoat recommends an N95 particulate respirator mask. For additional protection, a half mask respirator with organic vapor cartridge can be utilized. Eye protection recommended due to spray application method.
