The Awlgrip 545 Epoxy Primer is a versatile primer for application over filled and repaired surfaces, before the final topcoat is applied. It is suitable for use both above and below the waterline.
Surface Preparation:
Aluminum: Sandblast or grind to 100% clean silver color, or treat with Alumiprep 33/Alodine 1201.
Steel: Sandblast/grind to SSPC-SP5-85 or Sa 2 1/2.
Gelcoat/Fiberglass: Sand with 100-150 grit paper.
Wood: Smooth sand with 80-100 grit paper.
Theoretical Coverage: 497 square feet per gallon at one mil dry (25 microns) or 165-248 square meters per gallon at the recommended dry film thickness. Calculated based on a theoretical transfer efficiency of 100%.
Mixing and Thinning:
This is a two-part system. You need to order the base primer either in gray or white along with the D3001 converter in the appropriate size. The mixing ratio is 1:1, so if you purchase 1 liter of primer, you will also need 1 liter of converter, making a total of 2 liters. Additionally, you must purchase the appropriate reducer (spray or brush) for application. For spray application, reduce up to 25% with T0006, and for brushing, reduce up to 10% with T0031.
Spray Application: Mix by volume one part 545 base with one part D3001 to a smooth, homogeneous mixture. Reduce up to 25% with T0006. The total mix ratio is 1:1 1/2 by volume. Example: 8 oz 545 base, 8 oz D3001, 4 oz T0006.
Brush/Roller Application: Reduce 5-10% with T0031. Below 75°F, you can use the Cold Cure Accelerator M3066 to maintain drying and curing times. The expected pot life at 77°F and 50% relative humidity is 16 hours.
Application:
Spray Application: Apply smooth, wet coats to fill and cover the profile of the surface. Two to three coats may be required, with 5 – 6.5 mils WFT, yielding 2-3 mils DFT.
Brush and Roller Application: Apply two coats at 3-4 mils WFT, yielding 1.0 – 1.5 DFT per coat. Allow 12-14 hours between coats. Light sanding between coats will improve the finish. For large rolling surfaces, back-brushing is recommended. Do not apply paint materials to surfaces hotter than 105°F or colder than 55°F. Do not attempt to cure products at temperatures below 55°F.
Note: Do not apply paint materials to surfaces less than 3°C or 5°F above the dew point, or to surfaces warmer than 41°C or 105°F. The ambient temperature should be at least 13°C / 55°F and no higher than 41°C / 105°F.
